  • [Title] Interobserver agreement in the interpretation of anal intraepithelial neoplasia.
  • BACKGROUND: Anal carcinoma incidence is increasing, and is highest among men with human immunodeficiency virus (HIV) infection who have sex with men.
  • Anal carcinoma and anal intraepithelial neoplasia (AIN) are ascertained on tissue histology, but requires invasive procedures.
  • Screening for AIN using anal cytology was suggested.
  • The authors evaluated agreement on cytologic and biopsy specimens from HIV-positive men undergoing anal carcinoma screening.
  • METHODS: One hundred twenty-nine HIV-positive men with a history of anal-receptive intercourse underwent anal cytology, anoscopy, and biopsy.
  • Fourteen of 29 (48.3%) cytology specimens and 36 of 47 (76.6%) biopsy specimens with consensus interpretation of high-grade squamous intraepithelial lesions (HSIL) were interpreted originally as HSIL by > or = 3 pathologists.

  • [Title] Human papillomavirus genotypes in anal intraepithelial neoplasia and anal carcinoma as detected in tissue biopsies.
  • Human papillomavirus (HPV) infection strongly correlates with the development of anal intraepithelial neoplasias and carcinomas; however, few studies have characterized the distribution of the specific subtypes of the virus in the varying grades of dysplasia.
  • This report characterizes the distribution of HPV 16/18 in surgical specimens with anal intraepithelial neoplasia (AIN) I-III and histological variants of anal carcinoma.
  • A total of 111 anal surgical specimens with no dysplasia (10), AIN I-III (53), and anal carcinomas (48) were evaluated for the presence of high-risk HPV infection and subtyped by nested PCR or the Invader Assay.
  • High-risk virus types were detected in progressively greater number of anal intraepithelial lesions from 56% in low grade to 88% in high grade.
  • Type 16 was the prevalent subtype and was noted in 28% of low grade and 68% of high-grade lesions.
  • Moderate dysplasias showed type 16 in 20%, a prevalence similar to that in low-grade lesions.
  • Most (89%) squamous carcinomas were associated with high-risk viruses, 68% with type 16, a prevalence similar to that noted in high-grade dysplasia.
  • The similarity in the prevalence of type 16 in high-grade dysplasia and squamous carcinomas suggests that anal intraepithelial lesion III is the true precursor of squamous carcinoma and warrants aggressive management.
  • Anal intraepithelial lesions II showed a virus distribution that was similar to low-grade dysplasia.

  • [Title] Frequency of occult high-grade squamous intraepithelial neoplasia and invasive cancer within anal condylomata in men who have sex with men.
  • Human papillomavirus causes anal condylomata, high-grade anal intraepithelial neoplasia, and anal squamous cell cancer.
  • We found high-grade intraepithelial neoplasia or squamous cell cancer in 75 (47%) of 159 HIV-seropositive men who have sex with men (MSM) and in 42 (26%) of 160 HIV-seronegative MSM with anal condylomata meriting surgery (P<.001, determined by use of the chi(2) test).
  • Anal condylomata in MSM often harbor high-grade intraepithelial neoplasia and squamous cell cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Penile intraepithelial neoplasia is frequent in HIV-positive men with anal dysplasia.
  • These patients have a strongly increased risk of HPV-induced anal cancer and its precursor lesion, anal intraepithelial neoplasia (AIN), and a moderately increased risk for penile cancer.
  • Only limited data exist on penile intraepithelial neoplasia (PIN) in HIV+MSM.
  • All high-grade lesions had high-risk-HPV-DNA-loads > or = 1 HPV-copy/beta-globin-gene-copy.
  • Cutaneous beta-HPVs were found in PIN and AIN, but beta-HPV-DNA loads were very low, irrespective of the histological grade. p16(INK4a) Expression was detectable in all PIN lesions and correlated both with the histological grade and with high-risk HPV-DNA loads.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Blind sampling is superior to anoscope guided sampling for screening for anal intraepithelial neoplasia.
  • OBJECTIVES: Anal cytology smears are either collected "blind" (swab inserted 4 cm into anal canal and rotated) or guided through an anoscope (transformation zone visualised and then sampled).
  • RESULTS: Regardless of smear order, guided smears were less likely to detect higher grade abnormalities than blind smears (15 v 27 cases, p = 0.001).
  • Regardless of smear technique, first performed smears were more likely to detect a higher grade abnormality than second performed smears (23 v eight cases, p < 0.001).
  • CONCLUSIONS: Blind cytology smears are superior to anoscope guided smears for screening for anal neoplasia in homosexual men.

  • [Title] Anal human papillomavirus infection and abnormal anal cytology in women with genital neoplasia.
  • OBJECTIVES: Describe the type-specific prevalence of anal HPV infection in women with lower genital tract intraepithelial neoplasia and cancer.
  • Describe the prevalence of abnormal anal cytology and identify risk factors for anal HPV infection and abnormal anal cytology in this population.
  • METHODS: We performed a cross-sectional study of women attending 2 university-based colposcopy clinics with high-grade lower genital tract intraepithelial neoplasia or cancer.
  • Participants received anal HPV testing/typing, anal cytology and completed a questionnaire detailing medical history and sexual behavior.
  • RESULTS: Of the 102 women enrolled, 92 (90%) had adequate beta-globin for analysis of HPV DNA status, and 47/92 women (51%) had detectable anal HPV.
  • Overall, 9 women (9%) had abnormal anal cytology, and 7 of those had corresponding anal intraepithelial neoplasia grade I (AIN I).
  • Women with vulvar disease had the highest proportion of abnormal anal cytology (21%) compared to women with cervical disease alone (7%), but this difference was not statistically significant (p=0.10).
  • Neither anal HPV infection nor abnormal cytology was significantly associated with anal sex practices, smoking or number of sexual partners.
  • CONCLUSIONS: Anal infection with high-risk HPV types is common in women with high-grade genital neoplasia, but was not associated with known risk factors for genital HPV infection.
  • Other unidentified risk factors may play a role in the anal HPV infection in this population.
  • Abnormal anal cytology was rare and larger studies are needed to identify risk factors associated with abnormal cytology and anal intraepithelial neoplasia in this population.

  • INTRODUCTION: Anal intraepithelial neoplasia is a precursor condition of squamous anal carcinoma.
  • The aim of this study was to analyse the results of a diagnostics protocol of Anal Intraepithelial Neoplasia in high risk population using anal cytology.
  • PATIENTS AND METHOD: The protocol is based on a visit in the outpatient department, clinical interview, physical examination and anal cytology evaluated by Bethesda criteria.
  • The cross-sectional observational study was designed to study the anal smear results and their relationship with risk factors.
  • In the overall series, 25 patients have been diagnosed with abnormal anal cytology: 9 atypical squamous cells of undetermined significance (ASCUS), 15 low-grade and 1 high-grade squamous intraepithelial lesions.
  • There were no significant associations between abnormal cytology results and the presence of anal condyloma (p = 0.22).
  • CONCLUSIONS: Our diagnostic protocol of anal intraepithelial neoplasia revealed 25% of patients with pre-invasive lesions of squamous anal cancer.

  • BACKGROUND: An association between human papilloma virus (HPV) infection and progression to anal intraepithelial neoplasia (AIN) and epidermoid cancer has been established.
  • OBJECTIVE: To know the prevalence of low and high grade AIN, as well as HPV infection in an anoreceptive patients group, infected or not, by human immunodeficiency virus (HIV).
  • Patients who accepted anal citology and high definition anoscopy and biopsies with a follow-up not minor of 3 months were included.
  • Anal cytology showed inflammatory alterations in 21 patients (28%), low grade intraepithelial lesion in 23 (52%); there were not patients with high grade epithelial lesion.
  • According to the high definition anoscopy, there were low grade intraepithelial lesion in 42 patients (95%) and high grade in 2 (5%).
  • Biopsy showed low grade intraepithelial in 26 patients (59%), high grade in 4 (9%) and inflammatory alterations in 14 (32%).
  • The HIV infection was associated with the presence of high grade AIN (p=0.002, OR 47.7) CONCLUSIONS: There is a high prevalence of AIN and HPV infection between patients with anoreceptive sexual relations.
  • The HIV infection is a risk factor for the development of high grade AIN.

  • [Title] Anal intraepithelial neoplasia in women with genital intraepithelial neoplasia.
  • OBJECTIVE: To estimate the prevalence of anal intraepithelial neoplasia in heterosexual women with genital intraepithelial neoplasia, and to compare anal cytology with colposcopy for their effectiveness in anal intraepithelial neoplasia screening.
  • METHODS: Women with confirmed intraepithelial neoplasia on the cervix, vagina, or vulva were referred for gynecologic oncology care.
  • All patients underwent anal cytology and high-resolution anoscopy.
  • RESULTS: Women with average age of 39.6 years (range 14 to 83 years) underwent anal cytology and anoscopy (N=205).
  • Of the 205 patients with genital intraepithelial neoplasia, 25 patients (12.2%) had biopsy-proven anal intraepithelial neoplasia.
  • Twelve patients (5.9%) had abnormal anal cytology (nine with atypical squamous cells of undetermined significance [ASC-US], three with low-grade squamous intraepithelial lesions [LSIL]).
  • None of the nine patients with anal ASC-US had biopsy-proven anal intraepithelial neoplasia.
  • Of the three patients with anal LSIL, two had anal intraepithelial neoplasia II and one had condyloma on biopsy.
  • However, 78 patients (38%) had abnormal anoscopy findings that resulted in 25 biopsy-proven anal intraepithelial neoplasias (8 anal intraepithelial neoplasia I, 5 anal intraepithelial neoplasia II, 12 anal intraepithelial neoplasia III)), condylomas (n=11), and hyperkeratosis (n=8).
  • Anoscopy identified 32% (25 patients) with anal intraepithelial neoplasia out of 78 abnormal anoscopic examinations.
  • In diagnosing anal intraepithelial neoplasia, anoscopy has 100% sensitivity and 71% specificity; anal cytology has 8% sensitivity and 94% specificity.
  • CONCLUSION: Patients with cervical, vulvar, and vaginal intraepithelial neoplasia have 12.2% prevalence of anal intraepithelial neoplasia and should be screened with high-resolution anoscopy.
  • In anal intraepithelial neoplasia screening, anoscopy is more sensitive but less specific than anal cytology.

  • [Title] Human papillomavirus and anal intraepithelial neoplasia.
  • PURPOSE OF REVIEW: A review of recent developments in the understanding of the natural history of anal squamous carcinoma arising from areas of high-grade anal intraepithelial neoplasia.
  • RECENT FINDINGS: Anal intraepithelial neoplasia is a consequence of chronic human papillomavirus infection in the anal canal and appears to be driven by high viral loads of human papillomavirus.
  • Anal intraepithelial neoplasia is equally prevalent in different age groups of men who have sex with men, but in other respects what is known of its natural history resembles that of cervical intraepithelial neoplasia.
  • Low-grade lesions frequently resolve, but high-grade lesions are much more stable.
  • HIV-positives who practise receptive anal intercourse are at highest risk of anal intraepithelial neoplasia.
  • Screening is easy to perform using cytology; the limitations of anal cytology being similar to those of cervical cytology.
  • Patients with any grade of cytological abnormality require further investigation, ideally with high-resolution anoscopy, every 6 months.
  • Successful treatments for individual small to medium-sized high-grade lesions include trichloroacetic acid, infra-red coagulation and laser.

  • [Title] The frequency of high-grade intraepithelial neoplasia in anal/perianal warts is higher than previously recognized.
  • A retrospective review of the prevalence of intraepithelial neoplasia (IN) in surgically removed perianal/anal warts from December 1995 to December 2004 was undertaken in patients referred to the Sexual Health Clinic at Royal Perth Hospital.
  • Perianal/anal IN within the warts was found in 78% (52% high grade) of men with HIV infection.
  • In men without HIV infection, the overall rate of IN within warts was 33% (20% high grade).
  • The IN rate was 8.3% for HIV-negative women (2.8% high grade).
  • Rates of IN within perianal/anal warts in men with or without HIV infection are higher than previously reported, and suggest the likelihood of a substantial increase in the future incidence of anal cancer.

  • BACKGROUND: The natural history of anal intraepithelial neoplasia (AIN) is uncertain.
  • METHODS: All patients were diagnosed with high-grade AIN (AIN III) between 1994 and 2003.
  • Diagnosis was by full-thickness biopsy and histopathological examination.
  • Excision of localized high-grade AIN was carried out in 28 patients with minimal morbidity.
  • Six patients were systemically immunosuppressed at diagnosis, all of whom had multifocal perianal lesions.
  • Three immunosuppressed patients developed invasive anal squamous carcinoma during follow-up.

  • [Title] Anal intraepithelial neoplasia: correlation of grade with p16INK4a immunohistochemistry and HPV in situ hybridization.
  • Accurate diagnosis and grading of anal intraepithelial neoplasia (AIN) can be problematic, especially in separating AIN from anal transitional-zone epithelium.
  • To investigate if p16 would help in more accurately diagnosing and grading AIN, particularly when attempting to distinguish benign transitional-zone epithelium from high-grade AIN, we separately assessed these stains in a blinded manner on a large number of consecutive anal biopsies and anal tissues and correlated the findings with the diagnosis and grade of AIN.
  • One hundred thirty-three consecutive anal tissue specimens, from 128 patients were studied.
  • One hundred and eight were anal biopsies and 25 were hemorrhoidectomy specimens.
  • The comparisons included AIN grade (negative, 1, 2, 3) with nuclear intensity of p16 IHC (0 to 3+), AIN grade with IHC nuclear staining patterns (contiguous, patchy/rare), AIN grade with HPV-ISH [negative, low-risk (LR), high-risk (HR)] and, nuclear intensity of p16 IHC with HPV-ISH.

  • [Title] Study on the prevalence of human papillomavirus in the anal canal of women with cervical intraepithelial neoplasia grade III.
  • OBJECTIVE: The objective was to evaluate the prevalence of human papillomavirus (HPV) in the anal canal of women with cervical intraepithelial neoplasia (CIN) grade III.
  • The women in group I who presented high-grade neoplasia in colpocytological tests underwent collection of material from the uterine cervix and anal canal for investigating HPV DNA using the Hybrid Capture II technique.
  • RESULTS: In group I, 39 women (97.5%) were positive for HPV in the uterine cervix and 14 women (35%) in the anal canal.
  • In group II, only four women (10%) had a positive HPV test, for both the uterine cervix and the anal canal.
  • CONCLUSIONS: The prevalence of HPV in the anal canal of the women with CIN III was greater than in the women without CIN III.

  • [Title] Clinical spectrum and virologic characteristics of anal intraepithelial neoplasia in HIV infection.
  • BACKGROUND: Anal intraepithelial neoplasia (AIN) represents a precursor lesion of invasive squamous cell carcinoma with a clear association to high-risk human papillomavirus (HPV) types.
  • HIV infection is strongly associated with a higher prevalence of genital HPV infection, a higher incidence of AIN, and, consecutively, an increased risk for anal cancer.
  • OBJECTIVE: The aim of this study was to determine the clinical spectrum of AIN and lesional HPV colonization in a cohort of homosexual men who were HIV positive and had a history of receptive anal intercourse.
  • RESULTS: Of all patients, 86% had anal HPV infection at their first visit.
  • Histologically, 7 (35%), 7 (35%), and 6 (30%) of the patients had AIN grade I, II, or III, respectively.
  • All verrucous lesions were graded as high-grade intraepithelial lesions in cytology, whereas 6 of the 11 leukoplakic lesions (55%) were low grade.
  • Standardized screening programs for anal cancer prevention and treatment protocols for AIN in patients infected with HIV must be implemented.

  • [Title] Performance characteristics of anal cytology and human papillomavirus testing in patients with high-resolution anoscopy-guided biopsy of high-grade anal intraepithelial neoplasia.
  • High-resolution anoscopy with biopsy was used as the standard for detecting high-grade anal neoplasia and was compared to detection of high-grade anal neoplasia by anal cytology, human papillomavirus testing, or the combination.
  • A specimen was taken for anal cytology and human papillomavirus testing, followed by high-resolution anoscopy with biopsy of any lesions.
  • RESULTS: Ninety-one percent of HIV-positive and 57 percent of HIV-negative MSM had anal human papillomavirus infection.
  • In HIV-positive men the sensitivity of abnormal cytology to detect high-grade anal neoplasia was 87 percent, and in HIV-negative MSM it was 55 percent.
  • Among HIV-negative men, 9 of 20 cases of high-grade anal neoplasia would have been missed because cytology was negative, but the addition of human papillomavirus positivity increased sensitivity for the combination to 90 percent.
  • CONCLUSIONS: Sensitivity and specificity of anal cytology and human papillomavirus testing are different in HIV-positive and HIV-negative MSM for detecting high-grade anal neoplasia when patients have high-resolution anoscopy-guided biopsy of lesions.
  • High-resolution anoscopy is an effective tool for diagnosing high-grade anal neoplasia.

  • [Title] Immunohistochemical expression of p16 and Ki-67 correlates with degree of anal intraepithelial neoplasia.
  • Anal intraepithelial neoplasia (AIN) is a human papilloma virus related lesion.
  • The objective of this study is to correlate p16 expression and cellular proliferation measured by Ki-67 staining with the degree of dysplasia in the anal canal and to determine the efficacy of these markers in diagnosing high-grade AIN.
  • Seventy-five anal specimens from 55 patients (37 men; 18 women; mean age: 48 y; median: 44 y; range 25 to 96 y) were studied including 35 normal/reactive lesions, 23 low-grade AIN (AIN I and condyloma), and 17 high-grade AIN (AIN II and III).
  • High-grade AIN often demonstrated p16 staining in more than one-third of the thickness of the epithelium in a diffuse/continuous fashion. p16 expression in low-grade AIN was often restricted to the lower 1/3 of the epithelium and/or was focal and discontinuous.
  • When positive p16 staining was defined as the presence of diffuse/continuous staining in more than one-third of the thickness of epithelium, the sensitivity, specificity, and accuracy of p16 as a marker for diagnosing high-grade AIN were 76%, 86%, and 84%, respectively.
  • When positive Ki-67 staining was defined as the presence of nuclear staining in more than 25% of the cells in more than one-third of the thickness of epithelium, the sensitivity, specificity, and accuracy of Ki-67 as a marker for diagnosing high-grade AIN were 71%, 84%, and 83% respectively.
  • Both p16 and Ki-67 are reliable markers for diagnosing high-grade AIN.

  • OBJECTIVES: Evaluation of anal intraepithelial neoplasia (AIN) is subjective.
  • Previous studies have shown p16 and Ki-67 expressions to correlate with AIN grade.
  • MATERIALS AND METHODS: Seventy-seven anal specimens were retrieved.
  • Fair agreement was observed using H&E diagnosis alone (kappa = 0.38, S = 0.56).
  • CONCLUSIONS: Interobserver agreement for diagnosis of AIN was fair when based solely on H&E preparation. p16 alone improved interobserver agreement and demonstrated superior agreement when compared with H&E, Ki-67, and H&E/p16/Ki-67 combined.

  • [Title] Expression of proliferative biomarkers in anal intraepithelial neoplasia of HIV-positive men.
  • BACKGROUND: Anal intraepithelial neoplasia (AIN), a human papillomavirus (HPV)-associated precursor lesion of anal carcinoma, is highly prevalent among HIV-infected individuals, especially in men having sex with men (MSM).
  • Early diagnosis and treatment of AIN might prevent development of anal cancer.
  • OBJECTIVES: We aimed to evaluate the expression of 8 promising proliferative biomarkers in anal dysplasia and to compare the efficacy of these markers in diagnosing high-grade AIN.
  • METHODS: Immunohistochemical analysis of minichromosome maintenance proteins (MCM3, MCM4, MCM6, and MCM7), p21, Ki-67, p16, and proliferating cell nuclear antigen (PCNA) was performed in a total of 49 specimens of normal anal mucosa and high- and low-grade anal dysplasia.
  • In the progression from normal epithelium to high-grade dysplasia, we found significant differences in the expression of all biomarkers.
  • A cutoff of 25% or 50% lesional immunopositivity for the 4 MCMs, Ki-67, and p16 resulted in 100% sensitivity and 100% specificity to diagnose high-grade AIN.
  • Sensitivity and specificity of PCNA and p21 for a high-grade AIN diagnosis were lower.
  • HPV-DNA was detectable in 100% of high-grade AIN and 87.5% of low-grade AIN lesions.
  • All MCMs, p16, Ki-67, and PCNA, but not p21 correlated with cumulative lesional high-grade HPV-DNA loads.
  • CONCLUSIONS: MCMs, Ki67, and p16 are reliable immunohistochemical adjuncts for diagnosing high-grade AIN.

  • [Title] Human papillomavirus and anal neoplasia.
  • Anal cancer is a rare disease in the general population, but the incidence of anal cancer is higher in certain at-risk groups, such as men who have sex with men (MSM), and immunosuppressed individuals, including those with HIV infection.
  • Among HIV-positive MSM, the incidence of anal cancer may be as high as 10 times greater than current rates of cervical cancer in the general population of women.
  • Anal cancer is associated with human papillomavirus (HPV) infection and may be preceded by high-grade anal intraepithelial neoplasia (HGAIN).
  • HGAIN and anal HPV infection are both highly prevalent in groups at risk for anal cancer.
  • Current issues include determining the effect of antiretroviral therapy on the natural history of HGAIN and the incidence of anal cancer, optimizing diagnostic and therapeutic approaches to HGAIN, and determining the potential for prophylactic HPV vaccines to prevent anal HPV infection and anal cancer in at-risk groups.

  • Anal dysplasia is common in HIV patients, especially in HIV-positive men having sex with men (MSM).
  • High-grade anal dysplasia can progress to invasive anal cancer.
  • As in cervical carcinoma, there is a cause and effect relationship between anal cancer and human papillomavirus (HPV) infection, especially with high-risk types such as HPV16.
  • Several experts have recommended screening programs for anal cancer, including anal cytology along the lines of the Pap smear in women.
  • Clinical inspection, lesion biopsy, and treatment of anal dysplasia are performed under high-resolution anoscopy.
  • Anal cancer is divided into cancer of the anal margin and cancer of the anal canal.
  • Early cancer of the anal margin is excised akin to squamous cell cancer of the exposed skin, whereas cancer of the anal canal is treated by radiochemotherapy.
  • Physicians working in the field of HIV/AIDS should regularly screen their patients for the presence of anal dysplasia and anal cancer.
  • Basic diagnostic workup includes clinical inspection of the perianal area, digital rectal examination, and anal cytology.

  • [Title] P16/CDKN2A and Ki-67 enhance the detection of anal intraepithelial neoplasia and condyloma and correlate with human papillomavirus detection by polymerase chain reaction.
  • The classification of anal intraepithelial neoplasia (AIN) in mucosal biopsies is subject to considerable interobserver variability.
  • The aim of this study was to determine whether Ki-67 and p16/CDKN2A immunolabeling enhanced diagnostic accuracy in the assessment of anal mucosal biopsies from patients with suspected human papillomavirus (HPV) infection.
  • The study consisted of 75 cases that were originally interpreted to represent normal anal transitional zone (n=15), fibroepithelial polyp (n=10), condyloma accuminatum (n=10), low-grade AIN (AIN1, n=20), and high-grade AIN (n=20), including 10 cases each of AIN2 and AIN3.
  • Thus, the final study group consisted of 17 samples of normal anal transition zone, 14 fibroepithelial polyps, 6 condylomata accuminata, and 38 cases of AIN (11 AIN1, 16 AIN2, and 11 AIN3).
  • None of the anal transition zone samples or fibroepithelial polyps showed Ki-67 or p16/CDKN2A staining.
  • All cases of high-grade AIN showed positive p16/CDKN2A staining.
  • We conclude that Ki-67 labeling detects anal HPV-related changes with a high degree of sensitivity and specificity, whereas increased p16/CDKN2A staining is strongly associated with high-grade squamous neoplasia.
  • These results indicate that a combination of these markers may aid interpretation of anal mucosal biopsy samples.

  • OBJECTIVES: To assess levels of episomal and integrated human papillomavirus type 16 (HPV-16) loads in HIV-seropositive men who have sex with men (MSM) in anal infection and to study the association between episomal and integrated HPV-16 loads and anal intraepithelial neoplasia (AIN).
  • Overall, 135 (54.7%) men provided 665 HPV-16-positive anal samples.
  • RESULTS: The HPV-16 DNA forms in anal samples were characterized as episomal only in 627 samples (94.3%), mixed in 22 samples (3.3%) and integrated only in nine samples (1.4%).
  • HPV-16 episomal load [odds ratio (OR) = 1.5, 95% confidence interval (CI) 1.1-2.1], number of HPV types (OR = 1.4, 95% CI 1.1-1.8) and current smoking (OR = 4.8, 95% CI 1.3-18.6) were associated with high-grade AIN (AIN-2,3) after adjusting for age and CD4 cell counts.

  • [Title] DNA methylation in anal intraepithelial lesions and anal squamous cell carcinoma.
  • PURPOSE: Anal intraepithelial neoplasia is associated with human papillomavirus infection and may progress to invasive squamous cell carcinoma (SCC), which is increasing in immunocompromised patients.
  • We hypothesize that anal intraepithelial neoplasia is associated with abnormal DNA methylation and that detection of these events may be used to improve screening programs.
  • EXPERIMENTAL DESIGN: Seventy-six patients were identified who underwent anal cytology screening and subsequent biopsy at our institution between 1999 and 2004.
  • The specimens from these patients included 184 anal biopsies [normal, n = 57; low-grade squamous intraepithelial lesion (LSIL), n = 74; high-grade squamous intraepithelial lesion (HSIL), n = 41; and invasive SCC, n = 12] and 37 residual liquid-based anal cytology specimens (normal, n = 11; LSIL, n = 12; HSIL, n = 14).
  • CONCLUSIONS: Aberrant DNA methylation is a frequent event in anal HSIL and SCC.

  • [Title] Anal intraepithelial neoplasia in a multisite study of HIV-infected and high-risk HIV-uninfected women.
  • OBJECTIVES: To study anal intraepithelial neoplasia and its associations with anal and cervical human papillomavirus (HPV), cervical neoplasia, host immune status, and demographic and behavioral risk factors in women with and at risk for HIV infection.
  • METHODS: In 2001-2003 participants were interviewed, received a gynecological examination, anal and cervical cytology testing and, if abnormal, colposcopy-guided or anoscopy-guided biopsy of visible lesions.
  • Exfoliated cervical and anal specimens were assessed for HPV using PCR and type-specific HPV probing.
  • Logistic regression analyses were performed, and odds ratios (ORs) estimated risks for anal intraepithelial neoplasia.
  • Low-grade anal intraepithelial neoplasia was present in 12% of HIV-infected and 5% of HIV-uninfected women.
  • High-grade anal intraepithelial neoplasia was present in 9% of HIV-infected and 1% of HIV-uninfected women.
  • In adjusted analyses among HIV-infected women, the risk factors for low-grade anal intraepithelial neoplasia were younger age [OR = 0.59, 95% confidence interval (CI) = 0.36-0.97], history of receptive anal intercourse (OR = 3.2, 95% CI = 1.5-6.8), anal HPV (oncogenic types only OR = 11, 95% CI = 1.2-103; oncogenic and nononcogenic types OR = 11, 95% CI = 1.3-96), and cervical HPV (oncogenic and nononcogenic types OR = 3.5, 95% CI = 1.1-11).
  • In multivariable analyses among HIV-infected women, the only significant risk factor for high-grade anal intraepithelial neoplasia was anal HPV infection (oncogenic and nononcogenic types OR = 7.6, 95% CI = 1.5-38).
  • CONCLUSION: Even in the era of highly active antiviral therapy, the prevalence of anal intraepithelial neoplasia was 16% in HIV-infected women.
  • After controlling for potential confounders, several risk factors for low-grade anal intraepithelial neoplasia differed from risk factors for high-grade anal intraepithelial neoplasia.

  • [Title] Perianal squamous cell carcinoma with high-grade anal intraepithelial neoplasia in an HIV-positive patient using highly active antiretroviral therapy: case report.
  • CONTEXT: Highly active antiretroviral therapy (HAART) has turned human immunodeficiency virus (HIV) infection into a chronic condition, and this has led to increased incidence of anal dysplasia among HIV-positive patients.
  • Routine anal evaluation including the anal canal and perianal area is recommended for this population, especially for patients infected by oncogenic human papillomavirus (HPV) types.
  • CASE REPORT: A 54-year-old homosexual HIV-positive man presented with a six-year history of recurrent perianal and anal warts.
  • He presented some condylomatous spreading lesions occupying part of the anal canal and the perianal skin, and also a well-demarcated slightly painful perianal plaque of dimensions 1.0 x 1.0 cm.
  • Both anal canal Pap smears and biopsies guided by high-resolution anoscopy revealed high-grade squamous intraepithelial lesion.
  • Biopsies of the border of the perianal plaque also revealed high-grade squamous intraepithelial lesion.
  • Histological analysis on the excised tissue revealed high-grade squamous intraepithelial lesion with one focus of microinvasive squamous cell cancer measuring 1 mm.
  • The patient showed pathological evidence of recurrent anal and perianal high-grade squamous intraepithelial lesions at the sixth-month follow-up and required further ablation of those lesions.

  • [Title] A double-blind, randomized controlled trial of the use of imiquimod cream for the treatment of anal canal high-grade anal intraepithelial neoplasia in HIV-positive MSM on HAART, with long-term follow-up data including the use of open-label imiquimod.
  • OBJECTIVE: To determine whether imiquimod was more effective than placebo for the treatment of high-grade anal canal intraepithelial neoplasia (HG-ACIN).
  • METHODS: Sixty-four HIV-positive patients were randomized to self-application of imiquimod cream or matched placebo into the anal canal three times a week for 4 months.
  • In the imiquimod group, four patients resolved and eight patients downgraded to low-grade squamous intraepithelial lesion (LSIL) with a median follow-up of 33 months.
  • Five of these patients cleared their anal canal intraepithelial neoplasia (ACIN) and four patients downgraded to LSIL.
  • During this extended follow-up period, 61% have exhibited sustained absence of high-grade squamous intraepithelial lesion (HSIL).

  • BACKGROUND: Numerous studies have established a link between human papillomavirus (HPV), squamous intraepithelial lesions (SIL) and carcinoma of the cervix.
  • RESULTS: The sensitivity, specificity, PPV and NPV of DNA hybrid capture HPV testing for detecting high-grade cervical intraepithelial neoplasia (CIN) were 86%, 44%, 26% and 93%, respectively.
  • The respective values for cytology detection of high-grade CIN were 17%, 97%, 56% and 82%.
  • CONCLUSION: HPV testing was significantly more sensitive for detecting high-grade CIN than cytology (86% vs. 17%).

  • [Title] Evaluation and Management of Anal Intraepithelial Neoplasia in HIV-Negative and HIV-Positive Men Who Have Sex with Men.
  • The incidence of human papillomavirus (HPV)-associated anal cancer in men who have sex with men (MSM) is striking and has not been mitigated by the use of highly active antiretroviral therapy.
  • Detection and treatment of high-grade anal intraepithelial neoplasia (HGAIN) may reduce the incidence of anal cancer.
  • Anal cytology is a useful tool to detect HGAIN; annual screening of HIV-positive MSM and biennial screening of HIV-negative MSM appears to be cost-effective.
  • Large prospective studies are needed to document the efficacy of screening and treatment of HGAIN on anal cancer incidence.
  • The HPV vaccine holds promise for primary prevention of anal cancer in MSM, but significant implementation challenges remain.

  • [Title] Anal intraepithelial neoplasia in the highly active antiretroviral therapy era among HIV-positive men who have sex with men.
  • OBJECTIVES: The incidence of anal cancer among men who have sex with men (MSM) has continued to increase since the introduction of highly active antiretroviral therapy (HAART).
  • The prevalence of the putative anal cancer precursor, anal intraepithelial neoplasia (AIN) was high among HIV-positive MSM prior to the availability of HAART but little is known about AIN since HAART was introduced.
  • A total of 357 HIV-positive MSM with no history of anal cancer completed a questionnaire detailing behaviors and medical history, anal cytology and human papillomavirus (HPV) testing, and high-resolution anoscopy with biopsy for detection of AIN.
  • RESULTS: Eighty-one percent of participants with available CD4+ cell counts at baseline had AIN of any grade; 52% had AIN 2 or 3; and 95% had anal HPV infection.
  • Our data indicate that HAART is not associated with a reduced prevalence of AIN and support measures to prevent anal cancer among HIV-positive MSM whether or not they are using HAART.

  • BACKGROUND: Anal intraepithelial neoplasia (AIN), a human papillomavirus (HPV)-induced potential precursor lesion of anal cancer, is frequent among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM).
  • So far, only a few prospective studies have been performed on the topical treatment of AIN, especially at the intra-anal location.
  • METHODS: High-resolution anoscopy (HRA) was performed and patients with AIN (grade 1-3) were treated with 5-FU twice weekly for a total of 16 weeks.
  • RESULTS: A total of 46 patients with AIN were included in this open prospective pilot study; 76% had multifocal disease and 74% had high-grade lesions (AIN 2 or 3).
  • Seventeen patients (37%) did not respond (unchanged grade of AIN in 16 patients and progression from low- to high-grade AIN in one patient).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Diagnostic significance and management principles of colorectal intraepithelial neoplasia].
  • OBJECTIVE: To discuss the significance of pathological diagnosis of colorectal intraepithelial neoplasia and its treatment principles.
  • METHODS: One hundred and fifty-eight cases with colorectal tumors were treated between January 2004 and June 2008, among them 73 cases of tumors were diagnosed as low grade intraepithelial neoplasia and 89 tumors as high grade intraepithelial neoplasia on biopsy.
  • RESULTS: With postoperative pathological examination, 109 cases (67.3%) were identified as infiltrative adenocarcinoma, among them 80 cases (89.9%) had been diagnosed as high grade intraepithelial neoplasia and the other 29 cases (39.7%) had been diagnosed as low grade intraepithelial neoplasia before the operation.
  • CONCLUSIONS: We should pay more attention to tumors with a diagnosis of intraepithelial neoplasia due to its high potential of malignancy.
  • When the lesion was highly suspected to be malignant, and the resection of the tumor would save the anal sphincter, the tumor should be treated with segmental resection.

  • [Title] Anal intraepithelial neoplasia and other neoplastic precursor lesions of the anal canal and perianal region.
  • Anal cancer is rare and this helps to explain why anal pre-neoplastic conditions are poorly understood, especially with regard to their natural history and management.
  • Anal intraepithelial neoplasia is closely linked to human papillomavirus infection and is particularly common in homosexuals and in immunosuppressed patients, especially those with HIV/AIDS.
  • The high regression rates of low-grade anal intraepithelial neoplasia may simply reflect inconsistent pathologic reporting.
  • Higher grades of anal intraepithelial neoplasia may remain static for long periods of time in immunocompetent patients, but those with HIV/AIDS show early and rapid malignant transformation.
  • In general, most anal pre-neoplastic conditions are best diagnosed by biopsy and treated by surgical excision, although local recurrence is a problem.
  • In anal Paget's disease, it is important to ascertain, at the time of diagnosis, whether it is due to a primary in-situ apocrine-type of neoplasia of the anus or if the disease is secondary to an invasive primary carcinoma of the rectum.

  • OBJECTIVE: To evaluate the efficacy of 5% imiquimod in HIV-positive male patients with anogenital warts or anal intraepithelial neoplasia (AIN), and to elucidate whether human papillomavirus (HPV) type and viral load were important for clinical outcome and recurrences.
  • Eighteen patients had a histopathological diagnosis of AIN-1.
  • CONCLUSIONS: The assumption that visible perianal warts are benign lesions in HIV-positive patients has to be reevaluated since an important number of such lesions could correspond to low-grade anal disease, which in turn could progress to high-grade anal disease or cancer.
  • Further studies are needed to document its utility to prevent high-grade dysplasia and/or anal cancer.

  • On the basis of these results, a band-like pattern of p16 staining and Ki67 positivity in >50% of the squamous cell nuclei were strongly associated with high-grade AIN.
  • 4 of 25 (16.0%) AIN II lesions comprising 9.8% of the 41 high-grade AINs (AIN II and III) showed spotty p16 positivity and <50% Ki67 positive nuclei.
  • We conclude that when used together and evaluated in conjunction with H&E stained sections, p16 and Ki67 immunoexpression is a useful adjunct in the diagnosis and grading of AIN.

  • [Title] Imiquimod leads to a decrease of human papillomavirus DNA and to a sustained clearance of anal intraepithelial neoplasia in HIV-infected men.
  • Anal intraepithelial neoplasia (AIN), a human papillomavirus (HPV)-associated precursor lesion of anal carcinoma, is highly prevalent in HIV-infected men having sex with men (MSM).
  • Standardized follow-up examinations included high-resolution anoscopy, anal cytology/histology, HPV typing, and DNA load determination for HPV types 16, 18, 31, and 33.
  • Five patients (26%) had recurrent high-grade AIN after a mean time of 24.6 months.
  • During follow-up, 58% of all patients (11/19) developed new anal cytological abnormalities in previously normal, untreated anal regions.
  • 55% of these new AIN lesions were high-grade lesions and most of them were located intra-anally and associated with high-risk HPV types not detectable before therapy.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] P16 and Ki67 Immunostains Decrease Intra- and Interobserver Variability in the Diagnosis and Grading of Anal Intraepithelial Neoplasia (AIN).
  • BACKGROUND: Significant variation is reported in the diagnosis of HPV-associated AIN.
  • We previously observed that band-like positivity for p16 in >90% of contiguous cells coupled with Ki67 positivity in >50% of lesional cells is strongly associated with high grade AIN.
  • This study was undertaken to determine if addition of p16 and Ki67 immunostaining would reduce inter- and intraobserver variability in diagnosis and grading of AIN.
  • DESIGN: H&E stained slides of 60 anal biopsies were reviewed by three pathologists and consensus diagnoses were achieved: 25 negative, 12 low (condyloma and/or AIN I) and 23 high (9 AIN II and 14 AIN III) grade lesions.
  • RESULTS: Addition of p16 and Ki67 immunostains reduced intra- and interobserver variability, improved concurrence with consensus diagnoses and reduced two-step differences in diagnosis.
  • Negative and high grade AIN diagnoses showed the most improvement in concurrence levels.
  • CONCLUSION: Addition of p16 and Ki67 immunostains is helpful in the diagnosis and grading of AIN.

  • [Title] Prevalence of perianal intraepithelial neoplasia in HIV-infected patients referred for high-resolution anoscopy.
  • All patients underwent anal canal and perianal high-resolution anoscopy in the office with biopsy of suspicious areas.
  • Patients with high-grade intraepithelial perianal lesions underwent multiple biopsies under general anesthesia in the operating room to rule out malignancy.
  • Office perianal biopsies diagnosed two patients with invasive squamous-cell carcinoma and nine with high-grade squamous intraepithelial lesion.
  • Seven of the nine patients with perianal high-grade squamous intraepithelial lesion on office biopsy were submitted to multiple biopsies under general anesthesia.
  • CONCLUSIONS: Perianal disease was common in this group of HIV-infected patients; 11 patients (21 percent of total) were diagnosed with squamous-cell carcinoma or high-grade squamous intraepithelial lesion.
  • Our data suggest that anal canal neoplasia often is accompanied by perianal disease and illustrates the need for biopsy of any suspicious perianal lesions.

  • OBJECTIVE: To evaluate the lymphatic vessel density (LVD) in radical prostatectomy using the lymphatic marker D2-40 and analyze if LVD is variable within the whole-mounting samples of prostatectomy in different areas of carcinoma, high- and low-grade prostatic intraepithelial neoplasia and nodular hyperplasia.
  • The LVD of D2-40 positive endothelial cells into the radical prostatectomy was estimated by drawing the areas of interest (lymphatic endothelium) dispersed along the prostate zone to facilitate the counting of the positive cells within prostate areas (normal-looking cells, hyperplastic cells, intraepithelial neoplasia and invasive neoplasia).
  • RESULTS: LVD counting for nodular hyperplasia of prostate, low-grade prostatic intraepithelial neoplasia, high-grade prostatic intraepithelial neoplasia and prostate carcinoma was 1.29, 1.20, 1.26 and 1.13, respectively.

  • [Title] Prevalence and type distribution of human papillomavirus in carcinoma and intraepithelial neoplasia of the vulva, vagina and anus: a meta-analysis.
  • This meta-analysis investigated human papillomavirus (HPV) prevalence in vulvar, vaginal and anal intraepithelial neoplasia (VIN, VAIN, AIN) grades 1-3 and carcinoma from 93 studies conducted in 4 continents and using PCR assays.
  • Overall HPV prevalence was 67.8%, 85.3% and 40.4% among 90 VIN1, 1,061 VIN2/3 and 1,873 vulvar carcinomas; 100%, 90.1% and 69.9% among 107 VAIN1, 191 VAIN2/3 and 136 vaginal carcinomas; and 91.5%, 93.9% and 84.3% among 671 AIN1, 609 AIN2/3 and 955 anal carcinomas, respectively.
  • HPV16 was found more frequently (>75%) and HPV18 less frequently (<10%) in HPV-positive vulvar, vaginal and anal carcinomas than in cervical carcinoma.
  • HPV prevalence in anal carcinoma was higher among women (90.8%) than men (74.9%), but no difference by gender emerged in North America.
  • In conclusion, approximately 40% of vulvar, 60% of vaginal and 80% of anal carcinoma may be avoided by prophylactic vaccines against HPV16/18.
  • This proportion would be similar for the corresponding high-grade lesions of the vagina and anus, but higher for VIN2/3 (75%) than for vulvar carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Anal condyloma prevalence among HIV infected patients].
  • BACKGROUND: In the general HIV-infected population, there are few data on the prevalence and risk factors for anal condyloma, precursor lesions for anal cancer.
  • Overall, 108 (23%) pts had histologically-confirmed anal condyloma (36, 15 and 11% of the respective populations), including 51 (47%) pts with only endoanal localisation.
  • Intraepithelial neoplasia of grade I was noted in 59 patients, of grade II in 10 and of grade III in 2 and an invasive endoanal cancer in 1.
  • In multivariate regression analysis, condyloma independent risk factor were history of gonococcia or syphilis (OR=0.54 (0.29-0.99)), and history of previous anal condyloma (OR=2.05 (1.07-3.92) in homosexual men, history of previous penis condyloma (OR=26.8 (2.3-309.6), and unprotected sexual intercourse (OR=7.5 (2.1-26.3)) in heterosexual men and CD4 cell count below 200/mm(3), (OR=8.9 (1.5-51.6)), receptive anal intercourse (OR=6.7 (1.7-25.8)) and history of previous anal condyloma (OR=25.4 (3.4-188.2)) in women.
  • INTERPRETATION: In the HAART era, systematic screening revealed a high rate of anal condyloma in all HIV positive pts (not only in homosexual men).
  • Anal examination should be proposed systematically to all HIV-infected patients.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Immunoreactivity of p16 in anal cytology specimens: histologic correlation.
  • BACKGROUND: Cytology has been proposed as a potential screening tool in the evaluation of squamous anorectal disease in view of the morphologic similarities between anal and cervical squamous lesions.
  • Due to potential diagnostic pitfalls in anal cytology, p16 overexpression in these specimens was studied.
  • The p16-positive cells were identified in cases of low-grade squamous intraepithelial lesion (LSIL) (n = 3 cases), high-grade squamous intraepithelial lesion (HSIL) (n = 22 cases), and invasive squamous carcinoma (n = 1 case), and in 2 cases with negative follow-up biopsies.
  • The sensitivity and specificity of p16 immunoreactivity in the detection of anal intraepithelial neoplasia or carcinoma were 72% and 71%, respectively.
  • CONCLUSIONS: The presence of p16 immunoreactivity is a good predictor of dysplasia in anal specimens.

  • [Title] Human papillomavirus vaccines and anal carcinoma.
  • PURPOSE OF REVIEW: To explore the possible role of current prophylactic vaccines against human papillomavirus (HPV) in the prevention of anal intraepithelial neoplasia and squamous cell carcinoma of the anus (SCCA).
  • In addition, more than 90% prevalence of HPV was found in anal intraepithelial neoplasia.
  • Trials of the bivalent and quadrivalent vaccines against HPV16/18 have shown nearly 100% efficacy against high-grade lesions of the cervix, vulva and vagina in uninfected women under 26 years of age.
  • Answers to some still open questions, notably vaccine efficacy in men and HIV-infected individuals and willingness to expand vaccination programmes to both sexes, are essential to predict the ultimate impact of HPV vaccines on the prevention of cancerous and precancerous anal lesions.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Risk of anogenital cancer after diagnosis of cervical intraepithelial neoplasia: a prospective population-based study.
  • Associations between HPV and vaginal, vulvar, and anal cancers are well established, but the full extent in terms of age and time since diagnosis of these associations is not well known.
  • The incidence rate ratios (IRRs) of vaginal, vulvar, anal, and rectal cancer in women with a history of a cervical intraepithelial neoplasm (CIN), grade 3, compared with women with no such history were estimated by use of multivariate Poisson regression.
  • FINDINGS: Women with a history of grade 3 CIN had increased risks of cancer of the vagina (6.74 [95% CI 5.24-8.56]), vulva (2.22 [1.79-2.73]), and anus (IRR 4.68 [3.87-5.62]).
  • For all four anatomical sites, the IRRs varied substantially with the amount of time that had elapsed since the date of first diagnosis of grade 3 CIN.
  • Analyses stratified by attained age during follow-up showed that the risk of cancer conferred by a history of diagnosis of grade 3 CIN was highly age dependent.
  • INTERPRETATION: This study confirms the known association between history of CIN, presumed HPV infection, and increased risk of cancers of the vagina, vulva, and anus by use of large and complete databases, but also shows that this risk varies both by the time from initial diagnosis of grade 3 CIN and by the age of the individual.

  • HIV-positive men who have sex with men (MSM) are at high risk of developing human papillomavirus-associated anal squamous cell cancer.
  • Similar to the management of cervical dysplasia, clinicians are treating high-grade anal dysplasia to prevent progression to cancer.
  • Infrared coagulation (IRC) is an outpatient treatment for high-grade anal dysplasia.
  • This retrospective clinical study reports on 68 HIV-positive MSM with 78 biopsy proven high-grade anal lesions.
  • Of the 74 evaluable lesions; 39 had anal intraepithelial neoplasia (AIN) 1, 20 had AIN 2, seven had AIN 3, and eight had normal epithelium.
  • The IRC showed 64% efficacy per treated lesion and shows promise as a treatment modality for high-grade anal dysplasia in this population.

  • [Title] Anal cancer prevention in HIV-positive men and women.
  • PURPOSE OF REVIEW: The incidence of human papillomavirus-associated anal cancer is unacceptably high among HIV-positive men who have sex with men, and possibly in HIV-positive women.
  • Unlike most other malignancies occurring in the HIV-positive population, anal cancer is potentially preventable, using methods similar to those used to prevent cervical cancer in women.
  • This review discusses the issues around screening to prevent anal cancer.
  • RECENT FINDINGS: Recent studies show that the incidence of anal cancer has increased since the introduction of highly active antiretroviral therapy in this population and now exceeds the highest incidence of cervical cancer among women reported anywhere in the world.
  • SUMMARY: The high incidence of anal cancer among HIV-positive individuals must not be ignored, since it may be preventable.
  • Given the current evidence and analogy with the cervical cancer prevention model, many clinicians believe that identification and treatment of high-grade anal intraepithelial neoplasia to prevent anal cancer are warranted.
  • When the expertise to do so exists, this is a reasonable approach, particularly if coupled with efforts to optimize further screening and treatment approaches, as well as efforts to document the efficacy of high-grade anal intraepithelial neoplasia treatment to reduce the incidence of anal cancer.

  • [Title] Screening for HIV-associated anal cancer: correlation of HPV genotypes, p16, and E6 transcripts with anal pathology.
  • BACKGROUND: HIV-positive men with a history of anal-receptive intercourse are at risk for anal cancer.
  • We determined whether human papilloma virus (HPV) biomarkers were correlated with anal pathology in these men.
  • HPV types 16, 18, 31, 52, 59, and 68 were associated with high-grade histology.
  • The number of HPV genotypes per anal swab was higher for anal intraepithelial neoplasia (AIN) 2/3 than for normal or AIN 1 histology [median, 5 types (interquartile range) (IQR), 3-7 versus 3.5 (IQR), 2-6; P = 0.0005].
  • In the multivariable logistic regression model, HPV genotypes 16 [odds ratio, 2.58; 95% confidence interval (95% CI), 1.31-5.08; P = 0.006] and 31 (odds ratio, 4.74; 95% CI, 2.00-11.22; P = 0.0004), baseline CD4 count < 400 cells/mm(3) (odds ratio, 2.96; 95% CI, 1.46-5.99; P = 0.0025), and Acquired Immunodeficiency Syndrome (AIDS)-defining illness (odds ratio, 2.42; 95% CI, 1.22-4.82; P = 0.01) were associated with high-grade histology after adjusting for age.
  • CONCLUSIONS: The presence of high-grade anal pathology (AIN 2/3) in HIV-positive men was associated with multiple HPV genotypes, HPV genotypes 16 and 31, and HPV 16 viral load.

  • METHODS: Immunocytochemical analysis of p16(INK4A), MCM5, and CDC6 expression was performed on 20 normal, 38 cervical intraepithelial neoplasia 1 (CIN1), 33 CIN2, 46 CIN3, 10 squamous cell carcinoma, 19 cervical glandular intraepithelial neoplasia (cGIN), and 10 adenocarcinoma samples.
  • RESULTS: All three markers showed a linear correlation between expression and grade of dysplasia. p16(INK4A) and MCM5 protein expression was upregulated in all grades of squamous and glandular dysplasia.
  • CDC6 protein was preferentially expressed in high grade lesions and in invasive squamous cell carcinoma.
  • CDC6 may be a biomarker of high grade and invasive lesions of the cervix, with limited use in low grade dysplasia. p16(INK4A) was the most reliable marker of cervical dysplasia.

  • Classification of cervical intraepithelial neoplasia (CIN) lesions in low-grade (CIN1) or high-grade (CIN2-3) ones is crucial for optimal patient management, but current histological diagnosis on bioptic samples is often hampered by inter-observer variability.
  • To allow objective classification, we have exploited the peculiar characteristics of chemiluminescence detection, such as high sensitivity and easy quantification of the luminescence signal, to perform sequentially in the same tissue section both an immunohistochemical quantitative detection of p16(INK4A) (a protein marker of high-grade CIN lesions) and an in situ hybridization for human papillomavirus (generally accepted as a necessary but insufficient cause of cervical carcinoma).
  • The multiplexed method allowed detection of two complementary biomarkers and provided discrimination between different lesions (non-neoplastic, low-grade and high-grade CIN).

  • [Title] Methylation of human papillomavirus genomes in cells of anal epithelia of HIV-infected men.
  • Intra-anal malignancies disproportionately affect individuals who engage in anal intercourse because of infection with human papillomaviruses (HPVs), with an increased risk attributed to infection with HIV because of a declining immunity against HPvs. Long-term persistence of HPVs suggests yet other mechanisms that determine the clinical outcome, however.
  • Because methylation of HPV DNA represses oncogene expression in cervical samples, we investigated whether this mechanism also occurs in HIV-positive men and studied the methylation of CpG dinucleotides overlapping with the HPV-16 enhancer and promoter in 16 anal samples.
  • In low-grade anal intraepithelial neoplasia (AIN), methylation was high in CpGs overlapping the viral enhancer but rare in promoter positions, whereas methylation was high in promoter regions in high-grade AIN, especially in samples with a high load of viral genomes.
  • Our study expands the observation and mapping of HPV DNA methylation to anal infections and the HIV-positive patient population.

  • Anal dysplasia caused by human papillomavirus (HPV) infection is common in the HIV-infected population and is a precursor to squamous cell carcinoma of the anus (SCCA).
  • Herein, we describe our initial experience in assessing the frequency and severity of anal intraepithelial neoplasia (AIN) in a newly formed anal dysplasia clinic in Seattle.
  • Forty-seven patients of the 122 patients who underwent biopsy (39%) had biopsy-identified low-grade AIN, and 47 (39%) had high-grade AIN (HGAIN).
  • We anticipate that the anal dysplasia clinic will enable our institution to participate in emerging HIV- and HPV-related AIN clinical trials.

  • [Title] Anal cytology: is there a role for reflex HPV DNA testing?
  • There is an increased incidence of anal squamous carcinoma and its precursor lesions (anal intraepithelial neoplasia [AIN]) among persons who engage in anal-receptive sex.
  • Analogous to cervical cancer screening, anal Papanicplaou (Pap) smears currently are used to screen these high-risk populations.
  • Human papilloma virus (HPV) has been implicated in anal carcinoma pathogenesis and this study was performed to assess the potential role of HPV DNA testing as an adjunct to anal cytology.
  • We correlated cytological diagnoses and HPV DNA (Digene Hybrid Capture [HC II] assay) in anal specimens collected in SurePath liquid medium from 118 patients; 54.8% of cases diagnosed as atypical squamous cells of undetermined significance (ASC-US) and 87.8% diagnosed as low-grade squamous intraepithelial lesion (LSIL) or above tested positive for high- risk HPV DNA (B+).
  • High-grade SIL (HSIL) was present in 31 of the 51 patients with follow-up.
  • Although a cytological diagnosis of ASC-US or above was a reliable indicator for AIN, cytology frequently did not accurately predict the grade of SIL in subsequent biopsy.

  • [Title] The role of cytology (Pap tests) and human papillomavirus testing in anal cancer screening.
  • OBJECTIVE: To assess anal oncogenic human papillomavirus (HPV) and anal cytology as screening tests for detecting high-grade anal intraepithelial neoplasia (AIN 2+), as this is an immediate anal cancer precursor.
  • METHODS: We did concomitant anal cytology, anal HPV testing and HRA with directed biopsies without knowing the results of each intervention.
  • The main outcome measures were the sensitivity, specificity, negative predictive value and positive predictive value of anal cytology and oncogenic HPV for the detection of AIN 2+.
  • RESULTS: Cytology was abnormal in 67% of patients: high-grade squamous intraepithelial lesion, 12%; low-grade squamous intraepithelial lesion, 43% and atypical squamous cells of undetermined significance, 12%.
  • Test performance characteristics for the detection of AIN 2+ using any abnormality on anal cytology were: sensitivity 84%, specificity 39%, negative predictive value 88% and positive predictive value 31%; using oncogenic HPV: sensitivity 100%, specificity 16%, negative predictive value 100% and positive predictive value 28%.
  • CONCLUSION: Anal cytology and HPV detection have high sensitivity but low specificity for detecting AIN 2+.
  • HIV-positive men who have sex with men have a high prevalence of AIN 2+ and require high-resolution anoscopy for optimal detection of high-grade anal dysplasia.

  • [Title] Anal-rectal cytology: correlation with human papillomavirus status and biopsy diagnoses in a population of HIV-positive patients.
  • OBJECTIVES: We describe the cytological distribution of disease, correlate cytological diagnoses with human papillomavirus (HPV) DNA status and surgical biopsy diagnoses, determine if CD4 counts correlate with lesion severity, and compare anal-rectal data of HIV-infected patients (primarily men) with cervical data.
  • MATERIALS AND METHODS: A retrospective search of the computerized database identified 118 HIV-positive patients who had anal-rectal cytology.
  • Cytology results were compared with available follow-up data including repeat anal-rectal cytology tests, surgical biopsy, CD4 counts, and HPV DNA polymerase chain reaction-based genotyping.
  • RESULTS: Cytological diagnoses included 3% unsatisfactory for diagnosis, 41% negative for intraepithelial lesion or malignancy (NILM), 23% atypical squamous cells of undermined significance (ASC-US), 31% low-grade squamous intraepithelial lesion (LSIL), and 2% high-grade squamous intraepithelial lesion (HSIL) (ASC-US/squamous intraepithelial lesion, 0.7:1).
  • Two anal intraepithelial neoplasia (AIN) II, 10 AIN III, and 1 invasive squamous cell carcinoma were histologically detected (11%).
  • CONCLUSIONS: Anal-rectal cytology is a useful screening test.

  • [Title] Treatment of anal human papillomavirus-associated disease: a long term outcome study.
  • Treatment for human papillomavirus (HPV)-associated anal canal disease has been unsatisfactory.
  • The objective of our study was to determine the treatment outcome in our cohort with anal HPV disease.
  • Eighty-eight patients (48.6%) with high-grade anal intraepithelial neoplasia (AIN) and 82 patients (45.3%) with low-grade AIN underwent treatment.
  • Treatment outcome showed no evidence of being affected by age, sexual preference, history of smoking or presence of high-grade disease.
  • Contrary to the current view that treatment of HPV-related anal disease is difficult, unrewarding due to recurrences and may lead to substantial morbidity, we demonstrate that effective treatment is possible for both low- and high-grade AIN.

  • [Title] Cost-effectiveness of screening high-risk HIV-positive men who have sex with men (MSM) and HIV-positive women for anal cancer.
  • BACKGROUND: Anal cancer is uncommon and predominantly a disease of the elderly.
  • Individuals who are human immunodeficiency virus (HIV)-positive are particularly vulnerable to HPV infections, and increasing numbers from this population present with anal cancer.
  • OBJECTIVE: To estimate the cost-effectiveness of screening for anal cancer in the high-risk HIV-positive population [in particular, men who have sex with men (MSM), who have been identified as being at greater risk of the disease] by developing a model that incorporates the national screening guidelines criteria.
  • Papers that met the inclusion criteria contained the following: data on population incidence, effectiveness of screening, health outcomes or screening and/or treatment costs; defined suitable screening technologies; prospectively evaluated tests to detect anal cancer.
  • RESULTS: The reference case cost-effectiveness model for MSM found that screening for anal cancer is very unlikely to be cost-effective.
  • The negative aspects of screening included utility decrements associated with false-positive results and with treatment for high-grade anal intraepithelial neoplasia (HG-AIN).
  • However, combined with higher regression rates from low-grade anal intraepithelial neoplasia (LG-AIN), the lowest expected incremental cost-effectiveness ratio remained at over 44,000 pounds per quality-adjusted life-year (QALY) gained.
  • LIMITATIONS: Limited knowledge is available about the epidemiology and natural history of anal cancer, along with a paucity of good-quality evidence concerning the effectiveness of screening.
  • Further studies could assess whether the screening model has underestimated the impact of anal cancer, the results of which may justify an evaluative study of the effects of treatment for HG-AIN.

  • In line with the tendency during the last few decades to label flat precancerous lesions of various organs intraepithelial neoplasms, we may now also refer to dysplasia and carcinoma in situ of the urinary tract as low and high grade intraurothelial neoplasia, respectively.
  • To harmonize nomenclature, we now propose that the terms low and high grade papillary urothelial carcinoma be replaced by low and high grade papillary intraurothelial neoplasiafor all noninvasive urothelial cancers.

  • [Title] Anal carcinoma in human immunodeficiency virus-positive men: results of a prospective study from Germany.
  • BACKGROUND: Anal intraepithelial neoplasia (AIN), a human papillomavirus (HPV)-associated potential precursor lesion of anal cancer, is frequent among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM).
  • There is a paucity of data published on the progression of high-grade AIN to invasive cancer as well as on clinical and virological characteristics comparing anal margin and anal canal carcinoma.
  • OBJECTIVES: To search for anal carcinoma and AIN in a large series of HIV-positive MSM, to assess treatment response of anal carcinoma, and to analyse lesional HPV spectrum of anal cancers.
  • METHODS: Detection of anal carcinoma and AIN was performed using cytology, high-resolution anoscopy, and histology in case of abnormal findings.
  • Additionally, HPV analyses for 36 high- and low-risk α-HPV types were performed in patients with anal carcinoma.
  • Of these, 116 (26·0%) patients had normal findings, 163 (36·5%) had low-grade AIN, 156 (35·0%) had high-grade AIN, and 11 (2·5%) had anal carcinoma as evidenced by the highest grade of cytology/histology.
  • Five patients with anal cancer, who had refused treatment of their precancerous lesions, had progressed from high-grade AIN to invasive cancer within a median time of 8·6 months.
  • All anal cancers carried high-risk α-HPV types.
  • All five squamous cell carcinomas (SCCs) of the anal canal were HPV16 positive.
  • In contrast, only one of the four anal margin SCCs were HPV16 positive (HPV31, HPV33 and HPV33 + HPV68 were found in the other three anal margin SCCs).
  • In contrast to the cancer biopsies, a broad spectrum of surface high- and low-risk HPV types was found in anal swabs of the patients.
  • Surgical excision resulted in long-term disease control of all anal margin carcinomas, whereas combined chemoradiotherapy in carcinomas of the anal canal was associated with high recurrence rates, high toxicity, and high mortality.
  • CONCLUSIONS: Anal carcinoma and AIN are frequent in HIV-positive men, even in patients participating in anal cancer prevention programmes.
  • High-grade dysplasia in these patients can progress to invasive cancer within a short period of time.
  • Anal margin carcinoma and anal canal carcinoma differ substantially in their lesional HPV spectrum, prognosis and treatment response.

  • [Title] Performance of anal cytology in a clinical setting when measured against histology and high-resolution anoscopy findings.
  • OBJECTIVES: The success of cervical cytology in screening for cervical neoplasia has led to the concept of anal cytology screening for anal neoplasia.
  • Our objective is to study the performance of anal cytology as a screening tool.
  • DESIGN: We assessed anal cytology against histology and high-resolution anoscopy in a clinical setting.
  • METHODS: Anal pap test was obtained prior to high-resolution anoscopy examinations and biopsies.
  • RESULTS: From 395 individuals (93% men), 584 anal pap tests were obtained.
  • On the basis of 288 histology results, the sensitivity of anal cytology to detect disease was 70% [95% confidence interval (CI) 64-75], whereas the specificity was 67% (95% CI 38-88).
  • For high-grade disease (anal intraepithelial neoplasia 2/3), sensitivity of anal cytology was 81% (95% CI 70-90), and the negative predictive value was 85% (95% CI 76-92).
  • CONCLUSION: Anal cytology performs similar to cervical cytology in a clinical setting.
  • Sensitivity of anal smear is dependent on the area (quadrants) of disease present.
  • Sensitivity of anal cytology is enhanced when CD4 cell count is less than 400 cells/microl in HIV-positive men.

  • BACKGROUND: Self-collection of anorectal swab specimens could greatly facilitate the completion of prerequisite studies and future implementation of anal cancer screening among men who have sex with men (MSM).
  • Cytological abnormalities, noted in 47 (21%) of self-collected and 47 (21%) of clinician-collected specimens (with fair agreement, kappa = 0.414) included, respectively: ASCUS (5%, 5%), and low-grade (13%, 13%) and high-grade (3%, 3%) squamous intraepithelial lesions.
  • Among 12 men with biopsy-confirmed high-grade neoplasia, most had abnormal cytological results (including 6 patient and 9 clinician swabs) but few (2 patient and 1 clinician swab) were high-grade.

  • [Title] Management of anal cancer in 2010. Part 1: Overview, screening, and diagnosis.
  • Although anal cancer is a rare disease, its incidence is increasing in men and women worldwide.
  • Anal cancer is generally preceded by high-grade anal intraepithelial neoplasia (HGAIN), which is most prevalent in human immunodeficiency virus (HIV)-positive men who have sex with men.
  • Meta-analysis suggests that 80% of anal cancers could be avoided by vaccination against HPV 16/18.
  • Nearly half of all patients with anal cancer present with rectal bleeding.
  • According to the Surveillance Epidemiology and End Results (SEER) database, 50% of patients with anal cancer have disease localized to the anus, 29% have regional lymph node involvement or direct spread beyond the primary, and 12% have metastatic disease, while 9% have an unknown stage.
  • Clinical staging of anal carcinoma requires a digital rectal exam and a computed tomography scan of the chest, abdomen, and pelvis.
  • The 5-year relative survival rates are 80.1% for localized anal cancer, 60.7% for regional disease, and 29.4% for metastatic disease.
  • Part 2 of this two-part review will address the treatment of anal cancer, highlighting studies of chemoradiation.

  • [Title] Radiation therapy of recurrent anal squamous cell carcinoma in-situ: a case report.
  • INTRODUCTION: High-grade anal intraepithelial neoplasia, also referred to as anal squamous carcinoma in-situ, or Bowen's disease of the anus, make up less than 1% of all digestive system cancers in the United States.
  • The treatment of choice is surgical resection with anal mapping.
  • This can compromise the anal sphincter leading to leakage.
  • The initial lesion measured 3 cm in diameter on the right lateral side of the anal margin.
  • A standard surgery consisting of wide local excision with anal mapping was performed.
  • Our patient recurred with a 1.2 x 0.8 cm lesion on the left anal verge extending to the anal canal.
  • A biopsy along with mapping was done, and 2 of the 17 mapping specimens were positive for carcinoma in-situ, one in the anal canal.
  • Due to the location of the positive anal mapping, and in order to prevent sphincter compromise on re-excision, our patient was offered definitive radiation therapy.

  • [Title] Prevalence of anal cytologic abnormalities in a French referral population: a prospective study with special emphasis on HIV, HPV, and smoking.
  • PURPOSE: Studying anal cytology to detect intraepithelial neoplasia has been demonstrated to be useful in highly selected populations.
  • METHODS: An anal smear was proposed during each consultation during a three-month period.
  • No case of high-grade squamous intraepithelial lesion was found.
  • Four cases of low-grade squamous intraepithelial lesion were found, all in HIV patients with a history of condylomatous lesions.
  • The prevalence in this population of low-grade squamous intraepithelial lesion was 19 percent (4/21) in HIV seropositive males, and 15 percent (4/26) in the case of a past history of condyloma.
  • The factors associated with an abnormal smear (low-grade squamous intraepithelial lesion or atypical squamous cells of undetermined significance) were a history of anal condylomatous lesions (odd ratio, 4.9; range, 2.1-11.5), HIV seropositivity (odd ratio, 4; range, 1.6-9.9), and smoking (odd ratio, 2.1; range, 1.1-11.5).
  • CONCLUSIONS: This work confirms that the frequency of low-grade squamous intraepithelial lesion is raised in HIV-seropositive males and also where there is a history of condyloma, which corroborates the necessity for regular monitoring and screening of these patients at risk.
  • This study also suggests that the use of tobacco is associated with anal cytologic abnormalities.

  • [Title] Does HPV-status 6-12 months after treatment of high grade dysplasia in the uterine cervix predict long term recurrence?
  • BACKGROUND: Women once treated for high grade cervical dysplasia have a high long term risk for developing new dysplasia or cancer.
  • METHODS: Women with cervical intraepithelial neoplasi (CIN)2-3, treated for dysplasia and with recurrence of CIN2+ more than 2 years after treatment were compared with controls without recurrence, matched for age and date of treatment.
  • CONCLUSION: HPV-status 6-12 months after treatment of high grade dysplasia is of limited value for the design of long term follow up.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • More slides were classified as abnormal by imager read cytology (7.4% v 6.0% overall and 2.8% v 2.2% for cervical intraepithelial neoplasia of grade 1 or higher).
  • Among 550 patients in whom imager read cytology was cervical intraepithelial neoplasia grade 1 or higher and conventional cytology was less severe than grade 1, 133 of 380 biopsy samples taken were high grade histology.
  • Among 294 patients in whom imager read cytology was less severe than cervical intraepithelial neoplasia grade 1 and conventional cytology was grade 1 or higher, 62 of 210 biopsy samples taken were high grade histology.
  • Imager read cytology therefore detected 71 more cases of high grade histology than did conventional cytology, resulting from 170 more biopsies.
  • CONCLUSION: The ThinPrep Imager detects 1.29 more cases of histological high grade squamous disease per 1000 women screened than conventional cytology, with cervical intraepithelial neoplasia grade 1 as the threshold for referral to colposcopy.
  • More imager read slides than conventional slides were satisfactory for examination and more contained low grade cytological abnormalities.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • MAIN OUTCOME MEASURE: Relative sensitivity for cervical intraepithelial neoplasia of grade 2 or more at blindly reviewed histology, with atypical cells of undetermined significance or more severe cytology considered a positive result.
  • RESULTS: In an intention to screen analysis liquid based cytology showed no significant increase in sensitivity for cervical intraepithelial neoplasia of grade 2 or more (relative sensitivity 1.17, 95% confidence interval 0.87 to 1.56) whereas the positive predictive value was reduced (relative positive predictive value v conventional cytology 0.58, 0.44 to 0.77).
  • Liquid based cytology detected more lesions of grade 1 or more (relative sensitivity 1.68, 1.40 to 2.02), with a larger increase among women aged 25-34 (P for heterogeneity 0.0006), but did not detect more lesions of grade 3 or more (relative sensitivity 0.84, 0.56 to 1.25).
  • Results were similar when only low grade intraepithelial lesions or more severe cytology were considered a positive result.
  • CONCLUSION: Liquid based cytology showed no statistically significant difference in sensitivity to conventional cytology for detection of cervical intraepithelial neoplasia of grade 2 or more.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVE: To evaluate the proliferating capacity of atypical metaplastic cells in cervical smears by AgNOR technique and image analysis and investigate the probable relation with squamous intraepithelial lesions (SIL) using immunocytochemical assay for carcinoembryonic antigen (CEA).
  • STUDY DESIGN: Eight cervical smears were stained with Papanicolaou stain for diagnosis of atypical metaplastic cells.
  • The CEA was investigated by immunocytochemical staining in smears with atypical metaplastic cells and smears from high-grade squamous intraepithelial lesions (HSIL).
  • RESULTS: The mean AgNOR areas from atypical metaplastic cells (4.55, 6.66, 4.68, 5.30, 4.97, 6.20, 6.28, and 7.35) were significantly greater those that of intermediate metaplastic cells and cells from low-grade squamous intraepithelial lesions (LSIL) (0.77, 0.99, and 0.82, respectively).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • We evaluated the following markers: Ki67, Minichromosome Maintenance Protein-2 (Mcm-2), activated caspase-3 (a-casp3) and Bcl-2 to determine if they showed differential expression across progressive degrees of intraepithelial neoplasia and cancer in the prostate.
  • Tissue compartments representing normal, low grade prostatic intraepithelial neoplasia (LGPIN), high grade prostatic intraepithelial neoplasia (HGPIN), as well as different grades of cancer were mapped on H&E slides and adjacent sections were analyzed using immunohistochemistry.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Indole-3-carbinol (I3C) is a phytochemical (derived from broccoli, cabbage, and other cruciferous vegetables) with proven anticancer efficacy including the reduction of cervical intraepithelial neoplasia (CIN) and its progression to cervical cancer.
  • We show diminished PTEN expression during the progression from low-grade to high-grade cervical dysplasia in humans and in a mouse model for cervical cancer, the K14HPV16 transgenic mice promoted with estrogen.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • We previously used this probe set to show that cervical intraepithelial neoplasia (CIN) 2 and CIN3 lesions could be distinguished from normal samples, atypical squamous cell of undetermined significance (ASCUS) and CIN1, with a sensitivity and specificity exceeding 90%, independent of the cytomorphological assessment.
  • We conclude that the detection of 3q gain and amplification of TERC in routinely collected Pap smears can assist in identifying low-grade lesions with a high progression risk and in decreasing false-negative cytological screenings.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The risks for HPV-associated high-grade intra-epithelial neoplasia (IN) and cancer are also increased.
  • The prevalence of oral, anal, and cervical HPV infection in HIV-positive individuals compared with HIV-negative individuals increases with progressively lower CD4+ levels, as does incident high-grade IN.
  • In addition, epigenetic changes occur with increasing frequency in high-grade IN and cancer, such as hypermethylation leading to down-regulation of potential tumor suppressor genes.
  • Analysis of these data together suggests that immune suppression plays a more prominent role in the earlier stages of HPV-associated disease, up to and including incident high-grade IN.
  • Persistent high-grade IN and development of cancer may be more strongly related to the cumulative effect of HPV-associated genetic instability and the resulting host genetic changes.
  • There are few data to suggest a direct role for HIV in the pathogenesis of HPV-associated neoplasia, but HIV-associated attenuation of HPV-specific immune responses may allow for persistence of high-grade IN and sufficient time for accumulation of genetic changes that are important in progression to cancer.
