[Title] ARLTS1 polymorphisms and basal cell carcinoma of the skin.

Polymorphisms in the ARLTS1 gene, a member of the Ras super-family, have been associated with susceptibility in different cancer types.

The involvement of the gene in apoptotic signalling motivated us to study the role of ARLTS1 polymorphic variations in basal cell carcinoma of the skin (BCC).

In a case-control study, 529 cases diagnosed with BCC and 533 controls from Hungary, Romania and Slovakia were genotyped for the S99S (297G>A), P131L (392C>T), L132L (396G>C), C148R (442T>C) and W149X (446G>A) polymorphisms in the ARLTS1 gene.

No significant association between any of the single nucleotide polymorphisms (SNP) and risk of BCC (S99S, odds ratio (OR) 0.96, 95% confidence interval (CI) 0.601.53; P131L, OR 1.31 95%CI 0.742.31; L132L, OR 0.50, 95%CI 0.027.07; C148R, OR 0.50, 95%CI 0.691.18; and W149X, OR 1.01, 95%CI 0.372.79) was detected.

Furthermore, no significant difference in the distribution of haplotypes due to five polymorphisms in the ARLTS1 gene was found between the BCC cases and controls.

Our data rule out an association between variants in ARLTS1 and risk of BCC in the investigated population.

[Title] Basal cell carcinoma with progression to metastatic neuroendocrine carcinoma.

Merkel cell carcinoma (MCC) or primary cutaneous neuroendocrine carcinoma is a malignant tumor considered to demonstrate differentiation towards Merkel cells that are present at the base of the epidermis or around the apical end of some hair follicles and are thought to play a yet uncertain role in sensory transduction.

Here we present the case of a 54- year old female with a basal cell carcinoma (BCC) of the skin with neuroendocrine features (positivity for chromogranin) that has evolved during multiple recurrences and radiotherapy into a high-grade neuroendocrine carcinoma with morphological and immunohistochemical features of MCC (trabecular and nesting arrangement, positivity for chromogranin, cytokeratin 20, neuron specific enolase, and also neurosecretory granules on electron microscopy).

The progression from a chromogranin positive basal cell carcinoma of the skin, to a high-grade neuroendocrine carcinoma demonstrates the potential for cross differentiation among skin tumors.

[Title] Basal cell carcinoma of the eyelid in Finland during 1953-97.

PURPOSE: To study the incidence of basal cell carcinoma (BCC) of the eyelid in Finland.

METHODS: We studied 6241 cases of BCC of the eyelid reported to the nationwide Finnish Cancer Registry during 1953-97.

RESULTS: The incidence rates of BCC of the eyelid varied between 0.7 and 3.0 per 100 000 person-years in men and between 0.5 and 2.8 per 100 000 person-years in women during the study period.

The age-adjusted incidence rates of BCC of the eyelid increased during 1953-87 (p < 0.0001).

The incidence of BCC of the eyelid rose significantly with age.

There were no significant differences in standardized incidence ratios (SIRs) for BCC of the eyelid between different social class and occupation categories.

CONCLUSION: Age-adjusted incidence rates showed that BCC of the eyelid was more than twice as frequent during 1978-97 than before 1968.

Ageing may partly explain the increased incidence of BCC of the eyelid, whereas there were no differences in the SIRs for BCC of the eyelid between different social class and occupation categories in Finland.

[Title] [Markers expression of cell proliferation and apoptosis in basal cell carcinoma].

[Transliterated title] Expressão de marcadores de proliferação celular e apoptose em carcinoma basocelular.

BACKGROUND: - Basal cell carcinoma is the most common form of human cancer.

OBJECTIVE - To correlate markers expression of apoptosis (p53 and bcl-2) and cell proliferation (Ki-67 and PCNA) with histological indicators of tumor severity.

METHODS - Five samples of the nodular, morpheaform and superficial types of carcinoma were studied, respectively.One control group with three lesion-free patients was also included in the study.

The Mann-Whitney test was used to compare these markers expression with the manifestation form of basal cell carcinoma.

RESULTS - Bcl-2 expression was significant in basal cell carcinomas said to be aggressive (morpheaform and nodular types).

Of the studied tumors, 66.7% (n =10) strongly expressed p53.Our results show a greater expression of Ki-67 in nodular and superficial basal cell carcinoma, with no expression in the controls.

CONCLUSION - The findings allow us to conclude that Bcl-2 and p53 show a tendency to indicate the severity of basal cell carcinoma.

Also, PCNA was not a good marker of cell proliferation.

METHODS: X-ray mammograms were simulated from MRIs of 20 women using finite element methods for modeling breast compressions and employing a MRI/x-ray appearance change model.

Five mammography film readers independently identified landmarks (tumor, nipple, and usually two other normal features) on pairs of diagnostic and corresponding prediagnostic digitized images from 52 breast cancer cases.

Registration accuracy was sensitive to the type of landmark and the amount of breast density.

[Title] Pigmented basal cell carcinoma of the eyelid in Hispanics.

BACKGROUND: Pigmented basal cell carcinoma (PBCC) of the eyelid has not been well cited in the literature, and is often overlooked in the differential diagnosis of pigmented eyelid lesions.

METHODS: Retrospective review of patients with eyelid skin cancer who presented to the Department of Dermatology at the Keck School of Medicine of the University of Southern California and the Doheny Eye Institute from January 2002 to November 2005.

RESULTS: Sixty-nine of the 79 patients with eyelid skin cancer had basal cell carcinoma.

CONCLUSIONS: Although eyelid PBCC is regarded as a rare condition, it may occur more commonly in the Hispanic population and should be remembered in the differential diagnosis of pigmented eyelid lesions.

[Title] Long-term results after treatment of basal cell carcinoma of the eyelid in South-Western Finland.

: . PURPOSE: Basal cell carcinoma (BCC) is the most common skin cancer of the eyelid, showing an increasing incidence in the white population.

The authors studied the clinical characteristics and the treatment results of BCC of the eyelid in southwestern Finland during 1977-1997.

METHODS: The authors reviewed the case records of 191 patients with BCC of the eyelids treated at the Turku University Eye Clinic during 1977-1997.

RESULTS: The 191 patients had altogether 194 BCC tumors of the eyelid with the mean diameter of the tumor being smaller than 10 mm in 77.3% of cases.

Of the 194 BCC tumors of the eyelid 16.0% showed recurrence, and the recurrence rate of all surgically treated tumors was 13.7%.

In this study 61 patients (31.9%) developed other malignancies than the BCC of the eyelid including 28 patients (14.7 %) with carcinoma in other locations than skin.

CONCLUSIONS: Incompletely removed BCCs of the eyelid showed only 18.9% recurrence rate during the follow-up time.

On the other hand, BCCs of the eyelid should not be underestimated because of the rather high total recurrence rate.

The frequency of 31.9% of other malignancies than BCC of the eyelid is remarkably high and requires special attention from the ophthalmologist taking care of the patient with BCC of the eyelid.

[Title] Cost Analysis of Mohs Micrographic Surgery in High-Risk Facial Basal Cell Carcinoma.

[Transliterated title] Análisis de costes de la cirugía micrográfica de Mohs en el carcinoma basocelular facial de alto riesgo.

INTRODUCTION: Mohs micrographic surgery (MMS) is the treatment of choice for high-risk facial basal cell carcinoma (BCC) as it offers the greatest chance of cure with maximum preservation of healthy tissue.

OBJECTIVES: To determine the cost of MMS with fresh tissue to treat high-risk facial BCC and compare this to the estimated cost of conventional surgery in a Spanish public hospital.

MATERIAL AND METHODS: Cross-sectional study of a consecutive series of patients with high-risk facial BCC who underwent MMS at the Department of Dermatology at Hospital Costa del Sol in Malaga, Spain between July 2006 and December 2007.

RESULTS: Seventy-nine patients (mean age, 62 years) with 81 high-risk facial BCCs, 97.5% of which were primary tumors, underwent MMS.

Histology showed that 64% of the tumors were infiltrative or micronodular carcinomas.

Tumor-free margins were achieved in all patients, with no more than 2 stages required in 88% of the cases.

The most common surgical reconstruction techniques were direct closure (21%) and closure with a local skin flap or graft (71%); the corresponding estimates for conventional surgery were 2% and 89%, respectively.

CONCLUSIONS: MMS is a viable, effective technique that does not generate significantly higher costs than conventional surgery in selected patients with high-risk facial BCC.

[Title] Comparative analysis of immunohistochemical markers with invasiveness and histologic differentiation in squamous cell carcinoma and basal cell carcinoma of the skin.

BACKGROUND: This study evaluates several tumor-related markers to examine the expression pattern of markers according to the invasiveness and histopathologic differentiation of squamous cell carcinoma and basal cell carcinoma.

METHODS: Ninety-four cases of squamous cell carcinoma and 108 cases of basal cell carcinoma using tissue array in order to determine correlations between the expression of Ki-67, p53, EGFR, CD44v6, MMP-1 and MMP-3, invasiveness and histologic differentiation.

RESULTS: The depth of invasion showed a correlation with CD44v6 expression of tumor cell in both squamous cell carcinoma and basal cell carcinoma (P = 0.009, P = 0.036, respectively) and with the MMP-1 expression of stromal cell in squamous cell carcinoma (P = 0.010).

The differentiation of squamous cell carcinoma was correlated with Ki-67 index.

The loss of palisading arrangement in basal cell carcinoma was correlated with the MMP-1 expression of stromal cells (P = 0.045).

CONCLUSIONS: CD44v6 and MMP-1, expressed in tumor cells and stromal cells respectively, are significant markers associated with the invasiveness of tumors in squamous cell carcinoma and basal cell carcinoma of the skin and that it will be helpful to evaluate the invasiveness by measuring the expression of these markers.

[Title] Monoclonal antibody Ber-EP4 reliably discriminates between microcystic adnexal carcinoma and basal cell carcinoma.

It is diagnostically highly reliable in the differentiation between basal cell carcinoma and cutaneous squamous cell carcinoma.

In this study, we report its application in the differential diagnosis of microcystic adnexal carcinoma, desmoplastic trichoepithelioma and basal cell carcinoma.

METHODS: Biopsy samples from 28 sclerosing and infiltrating basal cell carcinomas, 13 microcystic adnexal carcinomas and 16 desmoplastic trichoepitheliomas were examined after immunohistochemical staining with Ber-EP4.

RESULTS: Ber-EP4 did not label any of the microcystic adnexal carcinomas, whereas all 28 basal cell carcinomas were Ber-EP4 positive.

Only one basal cell carcinoma was weakly positive.

Twelve of the 16 desmoplastic trichoepitheliomas were immunoreactive with Ber-EP4 and the staining was more variable than those of basal cell carcinomas.

CONCLUSIONS: Ber-EP4 reliably differentiates microcystic adnexal carcinoma from basal cell carcinoma to the same extent as it distinguishes the latter tumor from squamous cell carcinoma.

While it stains the majority of desmoplastic trichoepitheliomas, these tumors still have to be considered in the differential diagnosis with microcystic adnexal carcinoma, when Ber-EP4 is applied.

[Title] In vivo optical coherence tomography of basal cell carcinoma.

BACKGROUND: Optical coherence tomography (OCT) is a promising non-invasive imaging technique that has not systematically been studied in skin cancer such as basal cell carcinoma (BCC).

OBJECTIVE: We aimed, first, to describe the in vivo histologic features of BCC by using OCT, and second, to find out whether it is possible to differentiate BCC subtypes by means of OCT.

METHODS: Prior to the excision, the BCCs (n=43) as well as adjacent non-lesional skin sites were assessed by OCT in vivo.

RESULTS: Compared to non-lesional skin, a loss of normal skin architecture and disarrangement of the epidermis and upper dermis was observed in the OCT images of BCCs.

With regard to the aforementioned OCT features, no statistically significant (P<0.05) difference was found between nodular, multifocal superficial, and infiltrative BCCs, respectively.

CONCLUSIONS: OCT is capable to visualize altered skin architecture and histopathological correlates of BCC.

However, there is not at this time sufficient data supporting the clinical use of OCT for the differentiation of BCC subtypes.

[Title] Absence of the CHEK2*1100delC mutation in non-BRCA1/2 families with multiple cancer types in a high-risk clinic population of Caucasian ancestry.

: 11040 Background: Checkpoint kinase 2(CHEK2) is a cell-cycle-checkpoint kinase that phosphorylates p53 and BRCA1 in response to DNA damage.

The contribution of CHEK2 mutations to familial cancer has been widely studied in breast cancer.

Most notably, the CHEK2*1100delC mutation has been characterized to confer a 2-fold increased risk for breast cancer in carriers.

This finding comes from studies performed on Northern and Eastern European populations.

In contrast to the work done in Europe, these studies suggest a lower frequency of CHEK2*1100delC mutations in breast cancer families.

The aim of this study was to determine the frequency of CHEK2*1100delC in members of breast cancer families who tested negative for a deleterious mutation in BRCA1/2.

Families were characterized by the presence of several cases of breast and/or ovarian cancer and multiple members with other cancers in a single lineage.

RESULTS: No CHEK2*1100delC mutations were detected in 115 individuals, including 39 women diagnosed with breast cancer at an early age, 7 women with bilateral cancer, 2 men with breast cancer and 6 women with ovarian cancer, all of whom were negative for mutations in BRCA1/2.The CHEK2 Breast Cancer Consortium previously reported a frequency of 2.3% for the CHEK2*1100delC mutation among breast cancer cases from families with at least 2 cases of breast cancer (or breast and ovarian cancer) in a first- or second-degree relationship.

CONCLUSIONS: Our data are consistent with previous reports that suggest a lower frequency of CHEK2*1100delC mutations in North American hereditary breast cancer families without BRCA1/2 mutations and enriched for multiple cancer types.

The low frequency of the CHEK2*1100delC in the North American population limits its clinical relevance as a cancer predisposing gene.

[Title] Comorbidity prior to diagnosis in patients with common cancer diagnoses.

: e22180 Background: Chronic disease as diabetes, hypertonia and anemia may be associated with cancer risk as well as affect the short term survival of the malignancy.

METHODS: Using population based registry data from specialist and primary care in our health care region comorbidity in the form of anemia, hypertonia, diabetes, rheumatoid arthritis, chronic obstructive pulmonary diasease (KOL), and alcohol related diseases for patients with colon-, rectal-, lung-, prostate and breast cancer and survival were studied.

Altogether 2047 colon cancer cases, 985 rectal cancer cases, 2017 lung cancer cases, 3578 breast cancer cases and 5106 prostate cancer cases diagnosed 2000-2005 were included.

Comorbidity was studied prior to cancer diagnosis and in order to compare with the general population all first comorbidity diagnoses within 90 days were censored.

Patients with colon and rectal cancer had a higher prevalence of anemia, and diabetes.

Patients with lung cancer had a higher prevalence of anemia, KOL, diabetes, rheumatoid arthritis for both men and women and for men also a higher prevalence of alcohol related diseases.

Except for alcohol related diseases in females with breast cancer comorbidity for the above diseases was not significantly elevated for breast or prostate cancer.

Survival of the different cancer diagnoses was not significantly related to the comorbidity except for a tendency of worse survival for patients with alcohol related disease.

CONCLUSIONS: The prevalence of some common chronic diseases are elevated especially in colon-, rectal and lung cancer patients.

The comorbidity does not seem to affect short term survival of the cancer patient except for alcohol related diagnoses.

Our study also indicates the necessity to have all levels of care included in the study base of comorbidity and also emphasizes the need to censor time prior to diagnosis when comparing data with the general population.

[Title] Treatment of early breast cancer (EBC): A long-term follow-up study-GOCS experience.

: e11610 Background: Most cases of breast cancer are diagnosed at early stage of disease, therefore treatment is oriented to increase the relapse-free survival (RFS) and overall survival (OS).

RFS was analyzed from the date of initial diagnosis to the date of local or distant recurrence.

OS was estimated from the date of initial diagnosis to the last follow-up or date of death.

Adjuvant radiation therapy was administered to 73% of pts, whereas adjuvant chemotherapy to 29% and adjuvant hormone therapy to 18.5% of cases.

Local recurrence was documented in 37 pts (3.8%) whereas 269 developed metastatic disease (29%).

Bilateral breast cancer was seen in 102 cases (10.9%) and 91 pts (9.7%) developed 2nd malignancies.

This group of pts continues to have a good prognosis as shown by the OS rate at 5, 10, 15, 20 and 25 years, although high percentage of pts continue to have recurrence and die from breast cancer after 5, 10, 15, 20 and 25 years of follow-up.

[Title] Efficacy of capecitabine in secondary prevention of skin cancer in solid organ-transplanted recipients (OTR).

: 1519 Background: Skin cancers are the most common malignancies in OTR.

Topical 5% 5-FU has been used to successfully treat squamous cell carcinoma (SCC) in situ and actinic keratosis (AK).

Capecitabine, an orally-administered prodrug of 5-FU, in combination with interferon was shown to be effective in the treatment of advanced SCC of the skin.

This study was to determine the efficacy of low-dose capecitabine in secondary prevention of the skin cancers in OTR.

METHODS: OTR who developed recurrent skin cancers, SCC, and/or basal cell carcinoma (BCC), were given low-dose capecitabine 1g/m2 divided in two daily doses, day 1-14 of 21-day treatment cycle.

Skin surveillances were performed by dermatologists every 1 to 3 months.

Cumulative incidence rates of SCC, BCC, and AK before and after treatment were scored and statistically compared for each patient with a non-parametric Wilcoxon signed-rank test.

Mean incidence rates of SCC, BCC, and AK before treatment were 0.45, 0.05, and 4.99 lesions per month, respectively.

Mean incidence rates of SCC, BCC, and AK after treatment were 0.22, 0.04, and 2.80 lesions per month, respectively.

The differences in incidence rates of SCC, BCC, and AK before and after treatment were 0.24, 0.02, and 2.08 lesions per month with p value of 0.048, 0.844, and 0.151, respectively.

Age and the number of transplants were not significantly related to the change in incidence rates for all skin lesion types.

[Title] The impact of socioeconomic status (SES) on stage of cancer at time of diagnosis: A population-based study in Ontario, Canada.

: 6505 Background: Lower SES is known to be associated with worsened cancer survival.

Here we evaluate the impact of SES on stage of cancer at diagnosis in Ontario which has universal health insurance.

METHODS: All incident cases of breast, colon, rectal, non-small cell lung, cervical and larynx cancer diagnosed in Ontario 2003-2005 were identified using the Ontario Cancer Registry.

Stage information is only captured routinely for patients seen at Ontario's 8 Regional Cancer Centers (RCCs).

Using a best stage grouping approach, cases were assigned stage based on pathologic TNM if available and clinical TNM otherwise.

Using postal code at time of diagnosis cases were assigned to quintiles (Q); Q1 represents the communities where the poorest 20% of the Ontario population resided.

RESULTS: Stage at diagnosis was available for 19,239/23,254 (83%) of cases seen at RCCs.

Among cases with breast cancer, those in Q1 were less likely to have stage I disease (43 vs 47%, p = 0.004) and more likely to have stage IV disease (5 vs 4%, 0.008) than Q2-5.

With lung cancer, cases in Q1 were more likely to have stage I disease compared to Q2-5 (16 vs 13%, p = 0.015).

Distribution of stage I and stage IV disease did not differ by SES across other individual diseases.

However, for all 6 cancers combined, cases in Q1 were less likely than Q2-5 to have stage I disease (27 vs 30%, p = 0.001) and more likely to have stage IV disease (21 vs 18%, p < 0.0001).

We found significant gradients in 3-year overall survival across Q1-Q5 for breast (5% absolute difference in survival, p < 0.001), colon (4%, p = 0.049), and cervical (18%, p = 0.031) cancers.

CONCLUSIONS: Despite universal health care, SES remains associated with survival among patients with cancer in Ontario.

These data suggest that the difference in outcome is only partially explained by differences in stage at diagnosis.

[Title] The association of metabolic syndrome with triple-negative breast cancer.

: 1038 Background: Metabolic syndrome, a conglomerate of obesity, insulin resistance, hypertriglyceridemia, low HDL (high density lipoprotein), and hypertension is associated with an increased risk of breast cancer.

However, no clear association has been shown between the highly aggressive triple-negative breast cancer and metabolic syndrome.

METHODS: In a retrospective review we compared triple-negative and non-triple-negative breast cancer cases for the presence of metabolic syndrome by NCEP (National Cholesterol Education Program) or AACE (American Association of Clinical Endocrinologists) definitions.

Data on metabolic syndrome criteria, tumor size, grade, lymph node status, and ductal carcinoma in situ (DCIS) were reviewed.

RESULTS: The entire cohort of 176 patients (12.5% African-American) with median age 56.5 years (range 26-91 years) comprised of 86 triple-negative cases and 90 non-triple-negative cases.

A statistically significant association of triple-negative breast cancer with metabolic syndrome was observed.

Contrary to blood glucose, triglyceride, or HDL levels, which independently showed significant association with triple-negative breast cancer, hypertension, or BMI showed no independent association.

Additionally, triple-negative tumors displayed a significantly higher histologic grade and relative paucity of ductal carcinoma in situ (DCIS) when compared to the non-triple negative tumors (p < 0.001).

CONCLUSIONS: The data suggests that the metabolic syndrome is significantly more prevalent in triple-negative breast cancer patients when compared to the non-triple-negative patients.

Additionally, triple-negative breast cancer showed a significantly higher histologic grade and a relative absence of DCIS.

Whether the presence of metabolic syndrome preferentially increases the risk of developing triple-negative-breast cancer needs to be elucidated by future prospective studies.

[Title] The incidence of non-melanoma skin cancer after a single field treatment with aminolevulinic acid and blue light photodynamic therapy.

: e14646 Background: Non-melanoma skin cancer (NMSC) is the most common form of human cancer.

RESULTS: 43 Caucasian males (range 59- 87 yrs), 37 (87%) had history of NMSC on the face or scalp, 32 (78%) had basal cell carcinoma (BCC), 11 (22%) squamous cell carcinoma (SCC), 100% of patients had multiple (>4) AKs prior to treatment and 23 (75% ) had moderate to severe DH determined by Griffiths scale.

Prior to ALA-PDT 74 NMSC's were documented: 40 (54%) BCC and 34 (46%) SCC.

46 NMSC's were documented following ALA-PDT: 22 (48%) BCC and 24 (52%) SCC.

Prior to ALA-PDT, the frequency of BCC averaged 2 [IQR 1 to 3, max=4], and the frequency of SCC averaged 1 [IQR 1 to 1, max=3].

Following ALA-PDT, the occurrence of BCC averaged 1 [IQR 0 to 1, max=5], and that of SCC averaged 1 [IQR 0 to 2, max= 4].

The difference between BCC frequency before and after ALA-PDT treatment shown a significant reduction in BCC incidence (P = 0.0018).

No such differences were observed between the frequency of SCC before and after ALA-PDT (P=0.6230) Conclusions: A single ALA-PDT treatment to the face or scalp in high risk patients significantly reduces the incidence of BCC, the incidence of SCC was not reduced.

[Title] Contribution of BRCA1 and BRCA2 mutations to breast cancer in Tunisia.

: e22191 Background: Hereditary breast cancer accounts for 3-8% of all breast cancers.

It was recently estimated that a combination of BRCA1 and BRCA2 genes mutations is responsible for 30% of hereditary breast cancer cases.

METHODS: To investigate the prevalence of BRCA1 and BRCA2 gene mutations in breast cancer patients with affected relatives in Tunisia, 36 patients who had at least one first degree relative affected with breast and/or ovarian cancer were analysed.

Nineteen percent (7/36) of the familial cases were altered on BRCA1 or BRCA2 genes with deleterious mutations at heterozygous state and 55% (20/36) by mutation with uncertain value (UV) or by single nucleotide polymorphisms (SNPs).

CONCLUSIONS: Almost all the cases mutated by deleterious mutations on BRCA1 gene reported a family history of breast and/or ovarian cancer in the index case or in their relatives.

On the contrary, patients with an UV mutation or SNPs have no history of ovarian cancer in their corresponding families.

[Title] False-positive diagnosis of breast cancer by diffused optical tomography with ultrasound.

: e22085 Background: Breast cancer is one of the most common cancer in women.

Early detection, early diagnosis and early treatment play key role in fighting against breast cancer.

It provides dual modality images for early diagnosis of breast cancer.

The aim of this study was to evaluate the OPTIMUS system on diagnosis of breast disease.

METHODS: OPTIMUS system was applied to 160 breast tumor patients.

All patients had received surgical treatment and had definite pathological diagnosis.

OPTIMUS system was evaluated as diagnostic tool of breast tumor in this study.

RESULTS: There were 42 cases diagnosed as benign breast disease and 118 cases diagnosed as breast cancer by OPTIMUS system.

Pathology confirmed 60 cases of benign disease and 100 cases of breast cancer.

False positive rate of breast cancer was 30% (18/60).

False negative rate of breast cancer was 0% (0/100).

The pathology of false positive cases was mild and severe papillomatosis (6/18), non-typical hyperplasia (4/18), chronic inflammation (3/18), fibroadenoma (3/18) and fat necrosis (2/18).

Papillomatosis and non-typical hyperplasia are precancerous lesions and often difficult for clinical diagnosis.

CONCLUSIONS: OPTIMUS system is a non- invasive and highly effective diagnostic tool for breast disease.

Its sensitivity is reached to 100% and specificity is about 70% on the diagnosis of breast cancer.

OPTIMUS system could be used as assistant diagnostic tool for breast tumor.

[Title] Comparison of the sensitivity to endocrine therapy of PR+/ER- patients and ER+/PR- patients with HER2+ breast cancer.

: e11558 Background: Her2 and PR expression are important indicators for prognosis of breast cancer.

METHODS: Collected 3,677 primary breast cancer cases from 2002 to 2004 in Tianjin University Cancer Hospital.

All of the cases were confirmed by pathohistological method.

With Her2+ breast cancer, 168 patients are PR+/ER- and 211 patients are ER+/PR-.

With Her2+ BC, 3-year DFS(disease-free survival rate) of PR+/ER- patients is 94.53%, higher than that of PR-/ER+ ones (91.81%).With Her2- BC, 3-year DFS of PR+/ER- patients is lower than that of PR-/ER+ (p<0.05).

3. Total of 1853 cases with 5-year followed up, and 1297 cases have been given endocrine therapy.

CONCLUSIONS: With Her2+ breast cancer, 3-year DFS of PR+/ER- patients is higher than ER+/PR- and also PR+/ER- patients may more sensitive to endocrine therapy than ER+/PR- patients.

[Title] Molecular aetiology and pathogenesis of basal cell carcinoma.

Recent insights into the cell biology of the epidermis and its appendages are transforming our understanding of the pathogenesis of basal cell carcinoma (BCC).

The significant progress that has been made warrants a comprehensive review of the molecular and cellular pathology of BCC.

The items addressed include environmental and genetic risk factors, the biology of the putative precursor cell(s), and the contribution of aberrations in processes such as apoptosis, cell proliferation, differentiation and signalling to carcinogenesis.

[Title] Multiple hypersonographic spots in basal cell carcinoma.

BACKGROUND: High-frequency ultrasound is a useful method to obtain preoperative information regarding extension of basal cell carcinoma.

Its contribution to diagnosis is generally limited, however.

Recently, we observed hypersonographic spots in some cases of basal cell carcinoma.

OBJECTIVE: The present study was performed to determine the diagnostic value of this finding in this type of tumor.

MATERIALS AND METHODS: We conducted a retrospective study of archived sonographic images with a 30- or 15-MHz scanner and histology specimens of a total of 85 lesions, consisting of 29 basal cell carcinomas and 56 melanomas.

RESULTS: The findings were classified into four patterns as follows: Type A, multiple (more than five spots/lesion) hypersonographic spots (14 cases, 48%); Type B, sparse (3-5 spots/lesion) hypersonographic spots (7 cases, 24%); Type C, multiple moderate sonographic spots (3 cases, 10%); and Type D, sparse moderate sonographic spots (5 cases, 17%).

Histopathologically, these hypersonographic spots in BCCs seemed to correspond to calcification, horn cysts, or clusters of apoptotic cells in the centers of nests of basal cell carcinoma.

CONCLUSION: Multiple hypersonographic spots might become a useful finding for differential diagnosis between basal cell carcinoma and melanoma.

[Title] Pigmented reticular structures in basal cell carcinoma and collision tumours.

BACKGROUND: The dermatoscopic diagnosis of basal cell carcinoma (BCC) is based on well-known specific criteria.

Despite the fact that a pigment network is considered a negative feature for the diagnosis of BCC, its detection in a BCC context has been reported in 2.8% of cases.

OBJECTIVES: To determine whether pigment networks or network-like structures might represent a pitfall for the correct diagnosis of BCC.

METHODS: Dermatoscopic images of 412 histopathologically proven BCCs were analysed retrospectively.

RESULTS: Pigment network or network-like structures were detected in 14 of 412 (3.4%) BCCs.

Nine of 14 BCCs presented a typical pigment network, due to the association of a BCC lesion with a naevus, solar lentigo or actinic keratosis; two BCCs located on the face showed a pseudonetwork, and three of 14 lesions displayed a network-like structure characterized by light-brown irregularly meshed short linear structures, histopathologically related to a hyperpigmentation of the basal layer of the epidermis.

CONCLUSIONS: The presence of a pigment network in the context of a BCC is uncommon, and it usually reflects the association of BCC with a solar lentigo, naevus or a specific location of the lesion on photodamaged skin.

[Title] Basal cell carcinoma with intracranial invasion.

The risk of invasion and destruction of cranium, underlying dura, and cranial nerves by basal cell carcinoma (BCC) is extremely low, with an estimated incidence of 0.03%.

Intracranial BCC invasion by direct extension is rare, and orbital spread from a nasal lesion has not been reported in the literature.

We describe a case of intracranial invasion of a multiply recurrent nasal BCC, which caused progressive bilateral blindness from optic nerve compression, with spinal canal involvement causing subsequent lower extremity weakness and paralysis.

This case underscores the importance of early and appropriate treatment of high risk BCC, and aggressive treatment of recurrent lesions as early as possible.

[Title] Expression of ERp29, an endoplasmic reticulum secretion factor in basal-cell carcinoma.

To test if ERp29 is associated with the pathogenesis of skin cancer, in the present study we have assessed the expression of ERp29 in basal-cell carcinoma of the skin.

A bank of 104 basal skin carcinoma, including 50 nodular, 29 infiltrating, 15 superficial, 7 sclerosing, 2 fibroepithelial, and 1 pigmented cell carcinoma, were assessed by immunohistochemistry for ERp29 expression.

Thirty-nine (37.5%) of the samples tested expressed ERp29 with the infiltrating carcinomas displaying more intense (++,+++) immunoreactivity (6/29, P < 0.05) and the superficial carcinomas exhibiting the less intense anti-ERp29 staining (1/15, P < 0.05).

Collectively our results suggest that ERp29 is expressed in a subset of basal-cell carcinoma of the skin with the infiltrating carcinomas exhibiting the highest incidence of immunopositivity.

The role of ERp29 in the pathogenesis of the disease and its potential diagnostic value should be explored in future investigations.

[Title] [Basal cell carcinoma of the first toenail].

[Transliterated title] Carcinome basocellulaire de l'appareil unguéal de l'hallux.

BACKGROUND: Basal cell carcinoma is a very common form of skin cancer but its occurrence on the toenail unit is very rare.

We report such a case of basal cell carcinoma localized on the proximal nail fold of the right hallux.

CASE REPORT: A 67-year-old woman had a 7-year history of a non-healing ulcer on the proximal nail fold of the right hallux after antibiotics and treatment of her onychomycosis.

Bowen's disease and squamous cell carcinoma were suspected.

Histopathologic examination of a biopsy specimen revealed infiltrative basal cell carcinoma.

The lesion was surgically excised with a 0.5 cm margin and the defect was repaired by full-thickness skin graft with good functional and cosmetic results.

DISCUSSION: Basal cell carcinoma is the most common skin cancer but its localization on fingers, toes and nail units is very rare.

Only six cases of basal cell carcinoma on the toe nail unit have been reported to date in the literature.

Our case emphasizes the value of biopsy for all nail unit lesions of atypical appearance, course or therapeutic response.

[Title] Multidimensional non-linear laser imaging of Basal Cell Carcinoma.

We have used a multidimensional non-linear laser imaging approach to visualize ex-vivo samples of basal cell carcinoma (BCC).

A combination of several non-linear laser imaging techniques involving fluorescence lifetime, multispectral two-photon and second-harmonic generation imaging has been used to image different skin layers.

This approach has elucidated some morphological (supported by histopathological images), biochemical, and physiochemical differences of the healthy samples with respect to BCC ones.

In particular, in comparison with normal skin, BCC showed a blue-shifted fluorescence emission, a higher fluorescence response at 800 nm excitation wavelength and a slightly longer mean fluorescence lifetime.

The results obtained provide further support for in-vivo non-invasive imaging of Basal Cell Carcinoma.

[Title] No association between MDM2 SNP309 promoter polymorphism and basal cell carcinoma of the skin.

BACKGROUND: The MDM2 oncoprotein promotes cell survival and cell cycle progression by inhibiting the p53 tumour suppressor protein.

This SNP was also found to be associated with the onset and risk of different cancer types.

Basal cell carcinoma of the skin (BCC) is one of the most common neoplasms in the world.

BCC development is associated with environmental factors (especially sun exposure) as well as heritable factors.

OBJECTIVES: The present case-control study investigated the association of the MDM2 SNP309 with the risk and the age at onset of BCC.

Methods Data from 509 individuals affected by BCC and 513 healthy controls were genotyped with TaqMan polymerase chain reaction.

RESULTS: Cases and controls showed a similar genotype distribution and the SNP did not modify the age at onset of BCC.

CONCLUSIONS: These results suggest that the MDM2 SNP309 alone affects neither the risk nor the age at onset of BCC.

[Title] Tumor of follicular infundibulum is Basal cell carcinoma.

Tumor of follicular infundibulum (TFI) is currently thought to be a benign epithelial neoplasm with follicular differentiation.

It is encountered commonly in association with basal cell carcinoma (BCC), often as an incidental finding.

We reexamined 24 cases of TFI and noted, often only focally, many changes typical of BCC, including palisading of cells at the periphery of aggregations, germinative cells, follicular germs in the absence of a follicular papilla, crowding of cells, individual necrotic neoplastic cells, fibromucinous stroma, and clefts between aggregations of neoplastic cells and stroma.

Five cases were associated with BCC, and 2 of them showed obvious continuity between both types of lesions.

Moreover, we observed recurrences of what seemed to be a completely removed BCC in which tiny columns of cells typical of TFI were present in surgical margins.

Those findings prompted us to conclude that TFI may be one of many manifestations of BCC rather than a differential diagnosis of it.

[Title] Survey among patients with basal cell carcinoma in The Netherlands.

This paper describes the findings of a survey distributed among Dutch patients with basal cell carcinoma (BCC).

The questionnaire comprised a list of questions related to demographic characteristics, features of BCC, reason for consulting a dermatologist, anxiety, type of treatment and the satisfaction with this treatment and desired benefits of treatment.

Half of the patient group had already previously experienced a BCC.

Most patients (52%) indicated that the diagnosis 'skin cancer' frightened them, but that they knew it could be treated.

Accordingly, most patients (70%) indicated that BCC had no or hardly any influence on their quality of life.

From the patient's perspective, efficacy, low recurrence rate and no or minor scarring are important features of a BCC treatment.

The number of BCC patients is growing, which will lead to a definite burden for dermatologists in the near future.

[Title] CD10 expression in trichoepithelioma and basal cell carcinoma.

BACKGROUND: Trichoepithelioma (TE) is a benign neoplasm that shares both clinical and histologic features with basal cell carcinoma (BCC).

METHODS: CD10 protein immunohistochemistry was performed on paraffin-embedded biopsies of 13 TE and 23 BCC diagnosed by routine microscopy.

Cases were analyzed for pattern of CD10 expression by tumor cells and surrounding stroma.

Of these, eight cases also demonstrated positivity of the papilla, and two also showed positivity of the basaloid cells.

On the other hand, expression of CD10 by basaloid cells was identified in 20 (87%) cases of BCC.

Stromal positivity was also identified in three cases of BCC.

Condensation of CD10-positive stromal cells around basaloid nests was statistically significant in differentiating TE from BCC (p < 0.0001).

Conversely, CD10-positive basaloid cells were seen predominantly in BCC (p < 0.0001).

CONCLUSIONS: This study demonstrates a statistically significant difference in CD10 staining pattern between TE and BCC.

[Title] Extensive basal cell carcinoma with probable bone metastasis.

Metastasis of basal cell carcinoma (BCC) rarely occurs.

Few cases have been reported in the literature; those cases reported generally resulted from chronic, extensive, recurrent lesions on the head or neck.

With regard to bone metastases, several case reports have demonstrated similar clinical features indicative of osseous involvement.

We present a case report of a patient with an extensive BCC with histologic documentation and probable bone metastasis of BCC.

Clinical and radiographic features of this case were consistent with previously reported patients.

[Title] Identification of the cell lineage at the origin of basal cell carcinoma.

For most types of cancers, the cell at the origin of tumour initiation is still unknown.

Here, we used mouse genetics to identify cells at the origin of basal cell carcinoma (BCC), which is one of the most frequently occurring types of cancer in humans, and can result from the activation of the Hedgehog signalling pathway.

Using mice conditionally expressing constitutively active Smoothened mutant (SmoM2), we activated Hedgehog signalling in different cellular compartments of the skin epidermis and determined in which compartments Hedgehog activation induces BCC formation.

Activation of SmoM2 in hair follicle bulge stem cells and their transient amplifying progenies did not induce cancer formation, demonstrating that BCC does not originate from bulge stem cells, as previously thought.

Using clonal analysis, we found that BCC arises from long-term resident progenitor cells of the interfollicular epidermis and the upper infundibulum.

Our studies uncover the cells at the origin of BCC in mice and demonstrate that expression of differentiation markers in tumour cells is not necessarily predictive of the cancer initiating cells.

[Title] Idiopathic basal cell carcinoma in children.

Basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer in humans, and is the most common malignant neoplasm among adults in the US.

Childhood onset of BCC is rare and usually associated with genetic disorders such as basal cell nevus syndrome, Bazex syndrome, albinism, and xeroderma pigmentosum or due to radiation therapy.

A girl with idiopathic onset of BCC who was treated with Mohs micrographic surgery is reported.

A total of 108 children including this patient were reported with idiopathic de novo BCC.

Basal cell carcinoma in children is probably the result of genetic background and intense ultraviolet radiation exposure.

[Title] Interventions for basal cell carcinoma of the skin.

BACKGROUND: Basal cell carcinoma (BCC) is the commonest skin cancer.

BCCs are slow-growing, locally invasive, epidermal skin tumours which mainly affect white skinned people.

OBJECTIVES: To assess the effects of treatments for basal cell carcinoma.

SEARCH STRATEGY: We searched the Cochrane Skin Group Specialised Register (January 2006), the Cochrane Central Register of Controlled Trials (The Cochrane LIbrary Issue 1, 2006), the Cochrane Database of Systematic Reviews (The Cochrane Library Issue 1, 2006), MEDLINE (2004 to January 2006), EMBASE (2005 to January 2006), the metaRegister of Controlled Trials (February 2006).

SELECTION CRITERIA: Inclusion criteria were adults with one or more histologically proven, primary basal cell carcinoma.

One study found no significant difference for recurrence at 30 months when Moh's micrographic surgery was compared to surgery for high risk facial BCCs, (RR 0.64, 95%CI 0.16,2.64).

When radiotherapy was compared to cryotherapy there were significantly fewer recurrences at one year in the radiotherapy group compared to the cryotherapy group.Short-term studies suggest a success rate of 87 to 88% for imiquimod in the treatment of superficial BCC using a once-daily regimen for 6 weeks and a 76% treatment response when treating nodular BCC for 12 weeks, when measured histologically.

AUTHORS' CONCLUSIONS: Overall there has been very little good quality research on treatments for BCC.

Most trials have only evaluated BCCs in low risk locations.

[Title] Management of basal cell carcinoma by surveyed dermatologists in Scotland.

BACKGROUND: The British Association of Dermatologists (BAD) has produced guidelines for management of basal cell carcinoma (BCC) in the UK.

OBJECTIVES: Our primary objectives were to assess the management of BCCs in Scotland and to compare it with BAD guidelines.

METHODS: In phase I of the audit, dermatologists in 14 centres across Scotland prospectively registered demographic and clinical data of all lesions suspected to be BCCs over a 6-week period between October and December 2000.

In phase II, details of management of these lesions were evaluated by case note review.

There were 524 clinically suspected BCCs seen in 470 patients; 164 lesions in 146 patients showed pathology other than BCC and were excluded from analysis, thus leaving 360 lesions available for analysis.

BCCs were equally distributed between the sexes, and lesions most commonly presented in those aged 71-80 years.

A diagnostic biopsy was taken in 22% of lesions, and the rest were treated definitively after a clinical diagnosis of BCC, of which 90% were confirmed on histology.

Nodulocystic lesions were the most common type of tumour, comprising 48% of lesions, and most BCCs were located on the head and neck region.

Correlation of the histological type of BCC and treatment received showed that nodulocystic and morpheic BCCs were managed as recommended.

There were more superficial BCCs treated with surgical excision than expected (22 of 34 lesions).

CONCLUSIONS: In general, BCCs are managed according to BAD guidelines in Scotland, but waiting times vary considerably.

[Title] Novel investigational drugs for basal cell carcinoma.

IMPORTANCE OF THE FIELD: In the United States, the annual incidence of basal cell carcinoma (BCC) is close to 1 million.

Ultraviolet radiation exposure is the main risk factor; however, the availability of ever more potent sunscreens and education have not prevented the rise in BCC incidence.

AREAS COVERED IN THIS REVIEW: This article summarizes our current understanding of the etiology and molecular mechanisms of BCC tumorigenesis and discusses the preclinical and clinical studies to identify agents with anti-BCC efficacy.

WHAT THE READER WILL GAIN: The discovery that hyperactive Hh pathway signaling causes several cancers, including BCC, has spawned the development of many pharmacologic inhibitors of Hh signaling.

Early clinical testing of the most advanced, GDC-0449, demonstrated impressive efficacy in patients with advanced BCC.

Other promising anti-BCC chemopreventive strategies include drugs that are already FDA-approved for treating other diseases.

TAKE HOME MESSAGE: Preclinical and clinical trials with pre-existing FDA-approved drugs suggest novel uses for BCC chemoprevention and treatment.

Also, new chemical entities that inhibit the Hh pathway show promise, and in combination with other drugs may provide a nonsurgical cure for this most common cancer.

[Title] An immunohistochemical study of laminin in basal cell carcinoma.

BACKGROUND: Laminins are components of the extracellular matrix that mediate cell adhesion, growth, migration, proliferation and differentiation.

Basement membrane (BM) laminins, in particular, may play a role in enhancing carcinoma cell motility.

AIM: To evaluate the distribution pattern of laminin in basal cell carcinoma (BCC), as regards the basement membrane, cellular cytoplasm, peritumoral lacunae and surface epithelium and to correlate laminin distribution with different variants of BCC.

PATIENTS AND METHODS: Skin biopsy specimens were obtained from 21 BCC patients for routine histopathological and immunohistochemical study.

Code No: MO638, which reacts with the terminal globular domain of the α5 chain) RESULTS: The majority of BCC cases showed patchy cytoplasmic distribution of laminin.

The BM expression of laminin, in most cases, was well defined, fine and linear with irregular areas of thickening.

CONCLUSION: Cytoplasmic and basement membrane laminin is important in the pathogenesis and invasion of BCC.

[Title] Dermoscopy-guided surgery in basal cell carcinoma.

BACKGROUND: In basal cell carcinoma (BCC), excision margins between 3 and 10 mm, according to site, size, borders, previous treatment and histology, can allow for radical excision in at least 95% of cases.

OBJECTIVE: The objective was to ascertain whether dermoscopy can detect more accurately the lateral borders in BCCs than clinical examination alone, and allow us to obtain radical excision in more than 95% of cases with only 2-mm excision margins.

METHODS: A prospective study was performed of 200 consecutive BCCs of the head and neck removed with 2-mm dermoscopically detected excision margins.

Morpheaform BCC, deeply recurrent BCC, BCC in Gorlin-Goltz syndrome, BCC located in sites not accessible through dermoscopy and superficial multifocal BCC were excluded.

All cases of excised BCC were submitted to a uniform method of histological examination of the whole specimen with serial parallel sections at 2-mm intervals.

RESULTS: In only three cases did surgical excision with 2-mm margins prove to be inadequate; in the remaining 197 cases, the excision margins were tumour-free.

The comparison of clinical and dermoscopic extension measurement showed concordance in 131 cases (65.5%).

In 69 cases (34.5%), dermoscopic evaluation showed a larger peripheral extension.

CONCLUSIONS: These results indicate that 2-mm dermoscopically detected excision margins can achieve histologically confirmed complete excisions in 98.5% of cases.

[Title] Androgen receptor expression helps to differentiate basal cell carcinoma from benign trichoblastic tumors.

Histologic differentiation between basal cell carcinoma and benign trichoblastic neoplasms such as trichoepithelioma and trichoblastoma can be difficult on small biopsies.

Recent studies have shown androgen receptor expression in a number of mature epithelial structures in the skin and in epithelial neoplasms including basal cell carcinoma.

These findings suggested that androgen receptor expression might be a useful adjunct in the histologic differential diagnosis between basal cell carcinoma and benign trichoblastic neoplasms.

Therefore, we performed immunohistochemical analysis of androgen receptor expression in 32 basal cell carcinomas and 10 benign trichoblastic tumors (6 trichoepitheliomas and 4 trichoblastomas).

In our study, at least focal expression of androgen receptor was detected in 78% of basal cell carcinomas.

These results confirm the lack of expression of androgen receptor in benign trichoblastic neoplasms and indicate that androgen receptor expression by tumor cells points to basal cell carcinoma as the most likely diagnosis.

[Title] Single nucleotide polymorphisms in DNA repair genes and basal cell carcinoma of skin.

In addition to environmental exposures like UV radiation and, in some cases, arsenic contamination of drinking water, genetic factors may also influence the individual susceptibility to basal cell carcinoma of skin (BCC).

In the present study, 529 cases diagnosed with BCC and 533 controls from Hungary, Romania and Slovakia were genotyped for one polymorphism in each of seven DNA repair genes.

The variant allele for T241M (C>T) polymorphism in the XRCC3 gene was associated with a decreased cancer risk [odds ratio (OR), 0.73; 95% confidence interval (CI), 0.61-0.88; P = 0.0007, multiple testing corrected P = 0.004].

The risk of multiple BCC was significantly lower among variant allele carriers than in non-carriers (P = 0.04).

Men homozygous for the C-allele for E185Q (G>C) polymorphism in the NBS1 gene showed an increased BCC risk (OR, 2.19; 95% CI, 1.23-3.91), but not women (OR, 0.84; 95% CI, 0.49-1.47).

The data from this study show overall risk modulation of BCC by variant allele for T241M polymorphism in XRCC3 and gender-specific effect by E185Q polymorphism in NBS1.

[Title] Histological characteristics of basal cell carcinoma of the eyelid.

PURPOSE: To evaluate the histological subtypes of basal cell carcinoma (BCC) of the eyelid and to determine their effect on the size, depth of invasion and need of retreatment of a nonselected patient material seen in south-western Finland.

METHODS: We studied the case records and the histological characteristics of BCC of the eyelid treated at the Turku University Eye Clinic during the years 1988 through 1997.

The material consisted 103 patients (103 BCC tumors of the eyelid).

RESULTS: In 78.3% of the cases, the diameter of the lesion was smaller than 10 mm.

The most frequent histological subtype was nodular (84.5%) followed by sclerosing (5.8%), micronodular (4.9%), keratotic (2.9%) and superficial (1.9%) types of BCC of the eyelid.

Only patients of the nodular subtype showed recurrences (11 cases).

However, some nodular types of BCC tumors smaller than 10 mm in diameter extended to a depth of more than 4.0 mm.

CONCLUSIONS: The nodular subtype of BCC should be regarded as a potentially invasive and recurrent tumor.

Histopathological examination and subtyping of all BCC tumors is recommended.

[Title] Excising basal cell carcinoma in general practice.

BACKGROUND: Currently there is much interest in the general practice management of basal cell carcinoma (BCC).

METHODS: A retrospective audit of histopathology reports from 91 excisions of BCCs.

RESULTS: Thirty-nine percent of BCCs in this series were located on the head or neck, compared with 75-94% from other series; 50% of BCCs from the head/neck contained an aggressive histological subtype, compared with only 10% from other sites; four out of 139 papers found regarding surgical management of BCCs were from primary care practice.

DISCUSSION: Significant differences exist between the location mix and histological types of BCCs treated in general practice with those reported in the research literature.

[Title] Correlations between the Sonic Hedgehog pathway and basal cell carcinoma.

The family received their name because when the D. melanogaster HH protein malfunctions the mutant fly ends up looking like a small prickly ball, similar to a curled up hedgehog.

The Sonic hedgehog (SHH) pathway is implicated in the etiology of the most common human cancer, the basal cell carcinoma (BCC).

Mutations in the receptor of SHH, the patched gene (PTCH), have been characterized in sporadic BCCs as well as those from patients with the rare genetic syndrome nevoid BCC.

Human PTCH is mutated in sporadic as well as hereditary BCCs, and inactivation of this gene is probably a necessary if not sufficient step for tumorigenesis.

Delineation of the biochemical pathway in which PTCH functions may lead to rational medical therapy for skin cancer and possibly other tumors.

[Title] Characteristic Ber-EP4 and EMA expression in sebaceoma is immunohistochemically distinct from basal cell carcinoma.

AIMS: There is considerable overlap between the histological features of sebaceoma and basal cell carcinoma (BCC).

The distinction between these two tumours is important due to the often more locally aggressive nature of BCC and the association of sebaceoma with the Muir-Torre syndrome.

The aim of this study was to describe the immunohistochemical reactivity of the cells in sebaceoma to Ber-EP4 and epithelial membrane antigen (EMA) and investigate the utility of this panel to differentiate sebaceoma from basal cell carcinoma.

A single case exhibited focal weak Ber-EP4 staining, predominantly in mature sebocytes and in < 10% of the tumour cells.

EMA was not expressed in the germinative cells of sebaceoma, but was expressed strongly in approximately 50% of mature sebocytes in all cases and highlighted the cytoplasmic vacuoles.

We reviewed the immunoreactivity of 51 cases of nodular BCCs and found moderate or strong BerEP4 expression in all cases with never less than 20% of the tumour staining.

Expression of EMA was uncommon in BCC (moderate or strong in 8%) and was confined to keratotic or squamoid areas.

CONCLUSION: The use of Ber-EP4 in combination with EMA, both widely used immunomarkers in histopathology, is a helpful aid in distinguishing sebaceoma from nodular BCC.

[Title] [Analysis of 41 cases of basal cell carcinoma in maxillofacial area].

OBJECTIVE: To explore the incidence, location and relationship between surgical margin and metastasis of basal cell carcinoma (BCC) in maxillofacial area.

METHOD: Retrospective study was undertaken of 41 cases of BCCs in the maxillofacial region diagnosed in histopathology during the period of 1996 to 2003.

RESULT: From 1996 to 2003, there were 41 cases of primary BBC in maxillofacial region, of whom 17 were males and 24 were females (male-to-female ratio, 1:1.41).

The age of BCCs patients was between 55-74 years old, the average age of female patients was 68.1 years old, and that of the male was 58.4 years old.

The lesions of BCCs were found in 13 cases in the nose (31.7%), 8 cases in scalp skin (19.5%), 7 cases in periorbital skin (17.1%), 7 cases in perioral region (17.1%), 4 cases in cheek skin (9.8%) and 2 cases in auricle skin (4.89%).

Of all the 41 patients, 4 patients were found to suffer regional lymph nodes metastasis or local bone destruction at the first visit (9.8%), 3 patients (7.3%) had a recurrent BCC.

[Title] Cytokeratin profile in basal cell carcinoma.

Origin of basal cell carcinoma (BCC) is still unclear.

We studied the cytokeratin (CK) profile in BCC using monoclonal antibodies against 12 CKs to further investigate the suggested origin of the tumor from follicular matrix cells or from follicular outer root sheath cells and to determine if BCC subtypes can be identified on the basis of their CK profiles.

Cases of pilomatricoma and samples of fetal skin served as controls to establish the CK profile in matrical cells and developing follicles during intrauterine life, that of the epidermis and cutaneous adnexa in adult life having been determined in a previous study.

The most significant findings were as follows: (a) CK 5 and CK 17 positivity in all the BCCs studied;.

(b) CK 7, CK 8, CK 18, and CK 19 positivity in 30/52, 33/52, 42/52, and 14/52 BCCs, respectively;.

(c) CK 14 negativity in almost all the BCCs studied; and (d) lack of CK 1 expression only in 2/2 morpheiform BCCs and 4/10 nodular BCCs.

The study suggests a tumorous differentiation toward follicular outer root sheath cells and, in most cases, also toward the glandular components of the pilosebaceous-apocrine unit.

No significant difference in the CK profile among the BCC subtypes studied was found.

[Title] Bcl-2 and CD10 expression in the differential diagnosis of trichoblastoma, basal cell carcinoma, and basal cell carcinoma with follicular differentiation.

BACKGROUND: Both trichoblastoma and basal cell carcinoma (BCC) of the skin are characterized morphologically by the proliferation of basaloid cells; however, BCCs are clinically associated with a more aggressive behavior.

An accurate diagnosis of these lesions is essential for effective, timely treatment and appropriate therapeutic decisions.

Bcl-2 and CD10 immunohistochemistry were performed in all cases and the patterns of expression were analyzed.

RESULTS: Bcl-2 is useful for the detection of BCC with diffuse expression in nests of basaloid cells, but cannot distinguish between BCC with follicular differentiation and trichoblastoma, as both lesions show the same pattern with positive and negative areas.

Conversely, CD10 expression can distinguish between trichoblastomas with peritumoral stromal staining and BCCs with epithelial staining.

If both stromal and epithelial areas are stained, these cases are classified as BCC with follicular differentiation.

CONCLUSIONS: CD10 is useful for distinguishing between BCC with widespread follicular differentiation and trichoblastomas.

[Title] Statin use and risk of basal cell carcinoma.

OBJECTIVE: We examined the association between statin use and basal cell carcinoma (BCC) risk.

METHODS: We identified all members of a large integrated health care delivery system with a diagnosis of a histologically proven BCC in 1997.

Subsequent BCCs were identified through 2006 from health plan electronic pathology records.

We used extended Cox regression to examine the independent association between receipt of statin therapy (ever vs never, cumulative duration) and risk of subsequent BCC.

RESULTS: Among 12,123 members given a diagnosis of BCC who had no prior statin exposure, 6381 developed a subsequent BCC during follow-up.

Neither "ever use of statins" (adjusted hazard ratio 1.02, 95% confidence interval: 0.92-1.12) or cumulative duration of statin (adjusted hazard ratio 1.02/year, 95% confidence interval: 0.99-1.11) was associated with subsequent BCC after adjustment for age, sex, and health care use.

There was also no significant association between use of non-statin antilipemics and subsequent BCC (adjusted hazard ratio 1.10, 95% confidence interval: 0.76-1.58).

LIMITATIONS: No information was available for BCC risk factors, such as sun sensitivity and sun exposure.

CONCLUSIONS: Among a large cohort of individuals with BCC, statin therapy was not significantly associated with risk of subsequent BCC.

[Title] Cytokine mRNA expression in basal cell carcinoma.

There is evidence that cytokines (CKs) play a significant role in the development and/or progression of skin cancer.

The aim of the present study was to investigate the mRNA expression of tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and IL-8 in biopsy specimens of basal cell carcinoma (BCC), and to compare the results with the mRNA levels of non-lesional skin of BCC patients and healthy subjects.

Skin samples were obtained from 22 patients with BCC (lesional, non-lesional) and 25 healthy subjects (controls).

Histological examination revealed 12 nodular BCCs and 10 superficial BCCs.

The mRNA levels of CKs observed in healthy controls did not significantly (P > 0.05) differ from non-lesional CK levels of BCCs patients.

However, IL-6 and IL-8 levels of lesional skin were significantly (P < 0.05) higher than the CK levels observed in non-lesional skin and controls, respectively. mRNA expression of IL-6 and IL-8 showed a significant positive correlation (r = 0.51; P < 0.05).

There was no significant (P > 0.05) difference between lesional mRNA levels of TNF-alpha and those levels observed in non-lesional skin and controls.

The mRNA expression of CKs found in nodular and superficial BCCs did not significantly differ (P > 0.05).

BCC is associated with a significant increase of IL-6 and IL-8 expression.

In accordance with previous studies our data suggest a role for IL-6 and IL-8 in the development and/or progression of BCC, since mRNA expression of both CKs are significantly increased in tumour tissue.

[Title] [The excision width in surgical treatment of basal cell carcinoma].

Basal cell carcinoma originates from pluripotent cells of basal layer of epiderm, external covering of hair follicles, sebaceous glands or other skin adnexa.

There are several types of basal cell carcinomas that may be manifested in over 12 clinical forms.

The analysis included 250 patients of both gender and different age, operated for basal cell carcinoma.

Clinical characteristics of basal cell carcinoma and the width of the excision were described.

It was concluded that the width of the excision of basal cell cancer was in relation to histological type.

[Title] Detection of residual basal cell carcinoma by in vivo confocal microscopy.

BACKGROUND: Near-infrared reflectance-mode confocal scanning laser microscopy (RCM) represents a novel imaging technique for microscopic analysis of skin lesions and may provide a noninvasive modality for the diagnosis of basal cell carcinoma (BCC).

OBJECTIVE: To determine the feasibility of detecting residual or clinically equivocal BCC using RCM.

METHODS: In this pilot study, RCM was used in three cases to characterize the histologic features of index lesions in vivo.

RESULTS: Evaluation of clinically equivocal lesions by RCM revealed features characteristic of BCC, including tightly packed nests of elongated, monomorphic, polarized nuclei and subjacent ectatic blood vessels with lymphocytes undergoing margination and rolling.

Conventional histology confirmed the presence of BCC in all cases.

CONCLUSION: We report the use of RCM in the confirmation of residual BCC in two cases and the tentative diagnosis with subsequent pathologic conformation of a third case in which a biopsy was previously inadequate.

Our results demonstrate that confocal microscopy may facilitate diagnosis of BCC in vivo and warrant further prospective study to quantify the sensitivity and specificity of this rapidly evolving imaging modality.

[Title] Basal cell carcinoma with matrical differentiation: expression of beta-catenin [corrected] and osteopontin.

Basal cell carcinoma with matrical differentiation is an extremely rare variant.

To date, only 12 cases have been described in the literature.

This tumor is a typical basal cell carcinoma with basaloid nests containing shadow cells identical to those of pilomatricoma and pilomatrical carcinoma.

We present two additional cases and have investigated the immunoprofile of .

The morphological and immunohistochemical features of these cases that we have found suggest that basal cell carcinomas with matrical differentiation belong to a spectrum of lesions deriving from hair follicles in which .

[Title] PARP-1 cooperates with Ptc1 to suppress medulloblastoma and basal cell carcinoma.

The patched (Ptc1) protein is a negative regulator of sonic hedgehog signaling, a genetic pathway whose perturbation causes developmental defects and predisposition to specific malignant tumors.

Humans and mice with mutated Ptc1 are prone to medulloblastoma and basal cell carcinoma (BCC), both tumors showing dependence on radiation damage for rapid onset and high penetrance.

In addition to increased formation and slowed down kinetics of disappearance of gamma-H2AX foci, we observed increased apoptosis in PARP-1-deficient granule cell progenitors after irradiation.

Double-mutant mice were also strikingly more susceptible to BCC, with >50% of animals developing multiple, large, infiltrative tumors within 30 weeks of age.

[Title] Basal cell carcinoma with perineural invasion: reexcision perineural invasion?

BACKGROUND: Perineural invasion (PI) in basal cell and squamous cell carcinomas, especially of the head and neck, has been reported to indicate an increased morbidity.

Reexcision perineural invasion (RPI), a benign mimic of tumoral perineural invasion, may present a difficult histologic differential diagnosis.

METHODS: We surveyed the medical literature for PI occurring in basal cell carcinomas to investigate the degree to which the reported cases occurred in reexcision specimens vs. primary biopsy specimens.

RESULTS: We found large retrospective studies of 14,120 basal cell carcinomas evaluated for PI in which 310 cases of PI were identified (2.2%), and 20 sporadic case reports of basal cell carcinomas with PI.

Of 310 cases of basal cell carcinoma with PI, 196 (63%) were in reexcision specimens.

CONCLUSION: The high percentage of PI occurring in reexcision specimens vs. primary excisions may indicate that many of the reported cases of basal cell carcinomas with PI are actually examples of RPI.
