[Title] Assessing the reproducibility of the microscopic diagnosis of sessile serrated adenoma of the colon.

INTRODUCTION: sessile serrated adenoma (SSA) is a recently described lesion that may be related to the development of up to 15% of colorectal cancers (CRCs).

MATERIAL AND METHODS: concordance between two pathologists in the diagnosis of serrated lesions of the colon was studied for 195 lesions (187 hyperplastic polyps and 7 serrated adenomas).

Possible diagnoses were: SSA, traditional serrated adenoma (TSA), hyperplastic polyp (HP), serrated polyp, tubular adenoma, or mixed lesions.

[Title] Osseous metaplasia in a tubular adenoma of the colon.

Flexible sigmoidoscopy revealed a 1.5 cm polyp 30 cm from the anus.

The polyp was removed during the sigmoidoscopy by electrocautery and sent for histological examination.

The polyp was a tubular adenoma with mild dysplasia.

The adenoma contained numerous foci of metaplastic bone.

This is the first case of osseous metaplasia in a tubular adenoma of the colon to be reported.

[Title] Osseous metaplasia in an ulcerating tubular adenoma of the colon: a case report.

Here we report a rare case of metaplastic ossification within a benign ulcerating adenoma and review the literature concerning the aetiology.

CASE PRESENTATION: A 63-year-old woman, who presented with a history of melaena, was found at colonoscopy to have a pedunculated ulcerating polyp.

Histological examination demonstrated multiple areas of osseous metaplasia within the polyp stroma.

CONCLUSION: Heterotopic ossification in colonic adenomas is a particularly rare phenomenon, with the majority of cases occurring within malignant lesions.

[Title] Clinico-epidemiologic study of the metabolic syndrome and lifestyle factors associated with the risk of colon adenoma and adenocarcinoma.

Prevention is clearly important and the present study aimed to clarify risk factors and to promote colon cancer screening.

RESULTS: Low-grade adenoma was more frequent among the elderly and in men.

All of the men and 87.5% of the women with high-grade adenoma or adenocarcinoma were aged≥45 and≥50 years, respectively.

In women, a larger waist circumference (=80 cm) increased the odds ratio for colon adenoma or adenocarcinoma (colon tumors) by 1.033 (95% confidence index (CI), 1.001-1.066; p=0.040).

Metabolic syndrome significantly increased the odds ratio of colon tumors in men, but not in women.

Cigarette smoking, drinking alcohol, and increased physical activity were significant risk factors for colon tumors in men, with odds ratios of 1.001 (95% CI, 1.000-1.002; p=0.001), 1.001 (95% CI, 1.000-1.003; p=0.047), and 1.406 (95% CI 1.038-1.904; p=0.028), respectively.

CONCLUSIONS: Colon tumors have a high prevalence in the elderly.

A larger waist circumference in women and metabolic syndrome in both men and women elevate the risk of colon tumors.

In addition, smoking, drinking, and excessive physical activity are risk factors for adenoma and adenocarcinoma in men.

[Title] [Abdominal obesity, insulin resistance, and the risk of colonic adenoma].

BACKGROUND/AIMS: Abdominal obesity and hyperinsulinemia or insulin resistance are of interest in connection with colon carcinogenesis.

We conducted a prospective case controlled study for the evaluation of relationship between abdominal obesity, insulin resistance, and colorectal adenoma.

METHODS: Fifty patients with colorectal adenoma and fifty healthy subjects were included in this study.

RESULTS: There were no differences in sex, serum insulin, FBS, HOMA-IR, TG, CROL between adenoma and control group.

Subjects with high BMI, WHR, percent body fat, and obesity were more likely to have colonic adenoma.

Multiple logistic regression analysis after adjusting confounding factors, had revealed that WHR was the most important independent risk factor for colon adenoma.

CONCLUSIONS: Abdominal obesity was most closely related to colonic adenoma.

However, insulin resistance was not related to colonic adenoma.

[Title] The interaction of age and hormone replacement therapy on colon adenoma risk.

BACKGROUND: Several studies have identified a possible interaction between age and hormone replacement therapy on colon neoplasm risk.

RESULTS: There was a significant interaction between age and hormone replacement therapy use (P=0.03) with current estrogen users who were over 56 years of age having a reduced odds of colon adenoma (OR, 0.40; 95% CI, 0.16-0.98) when compared to never users.

Both older women who had used hormone replacement therapy for 3 or less years (OR, 0.07; 95% CI, 0.006-0.81) and those reporting greater than 10 years of use (OR, 0.27; 95% CI, 0.09-0.80) had a reduced adjusted odds for adenomas when compared to non-users.

CONCLUSIONS: Duration of use is not likely to explain the stronger association of hormone replacement therapy use with colon neoplasm in older women.

[Title] A reduced COX-2 expression and a reduced number of pericryptal myofibroblasts are associated with depressed adenoma of the colon.

The histogenesis of depressed adenoma of the colon has not been sufficiently investigated.

Pericryptal myofibroblasts are stromal cells expressing smooth muscle actin, and are involved in the differentiation and multiplication of epithelial cells in the colonic epithelium.

COX-2 has been reported to be involved in the development of colon adenoma.

We studied the histogenesis of depressed adenoma of the colon by examining the relationship between the presence of pericryptal myofibroblasts and COX-2 expression.

Twenty-one depressed adenomas of the colon that had been resected endoscopically between June 1998 and May 2003 (mild-moderate atypia; mean diameter, 6.7 mm) and 23 elevated adenomas that had been resected endoscopically in 2003 (mild-moderate atypia; mean diameter, 11.7 mm), were studied.

Eighteen (78.3%) of the 23 elevated adenomas and six (28.6%) of the 21 depressed adenomas were positive for pericryptal myofibroblasts immunohistochemically, showing a significant difference (P<0.001).

Seventeen elevated adenomas (73.9%) and eight depressed adenomas (38.1%) were positive for COX-2 expression (P=0.016).

The histogenesis of depressed adenomas differs from that of elevated adenomas.

Our results suggest that a low number of pericryptal myofibroblasts and a low COX-2 expression are associated with depressed adenomas.

[Title] Mantle cell lymphoma in a tubular adenoma: unusual presentation with synchronous colonic carcinoma.

Colonoscopy at this time revealed 3 colonic tubular adenomas.

Reassessment of the histology of the colonic polyps and appropriate immunohistochemical stains showed that the lamina propria of one of the tubular adenomas was infiltrated by MCL.

Reexamination of the sections taken at the time of the original sigmoidectomy showed MCL in 2 of the regional lymph nodes removed at that time, but no evidence of lymphoma in the colon was found.

To our knowledge, this is the fifth reported case of synchronous occurrence of intestinal MCL and colonic carcinoma and the first report of MCL presenting in a tubular adenoma of the colon.

The authors aimed at evaluating CD24 protein expression in adenoma and adenocarcinoma of the stomach, colon, gallbladder, ovary, and breast to establish a correlation with clinicopathologic data.

The present study clearly demonstrates that CD24 is abundantly expressed in adenocarcinoma compared to adenoma of the colon and breast.

Intracytoplasmic CD24 expression was found to be highly associated with adenocarcinoma of the colon, gallbladder, and ovary compared to the adenoma group of those organs, and with the positive nodal status compared to the negative nodal status of the colonic adenocarcinoma.

Then, the results of a randomized double-blind clinical test that examined the regressive effect of a COX-2-specific inhibitor on adenoma of familial adenomatous polyposis (FAP) are presented.

These results suggest that a higher dose of COX-2 inhibitors has a suppressive effect on adenoma of the colon and rectum, although a moderate clinical dose of COX-2 inhibitors does not induce clinically effective suppression of adenoma.

: 11059 Background: Since the pathologic stage is the most powerful prognostic factor for colorectal cancer (CRC), there is a strong need of non-invasive methods for early detection.

METHODS: cfDNA was extracted from plasma samples from 136 patients with primary CRC at different stages [median age 64 yrs; male/female 78/58; stages I-II, 61; stages III-IV, 75], and from 24 patients with adenomas [median age 67 yrs; male/female 17/7)] and from 55 clean-colon healthy subjects [median age 56 yrs; male/female 13/43).

The levels of cfDNA (ALU-115, ALU-247) of CRC patients (stages I-II and stages III-IV) were compared with those of healthy subjects and patients with adenoma.

RESULTS: The median concentrations of total cfDNA (ALU115) in the plasma samples from patients with stages III-IV and stages I-II CRC, adenoma and normal controls were 52,4, 11.9; 1.9, and 1.7 ng/ml, respectively (p<.0001).

With a cut-off of 4.86 ng/ml, total DNA (ALU115) showed a sensitivity of 78.52 (95% CI 70.6-85.1) and a specificity of 86.08 (95% CI 76.4-92.8) in distinguishing patients with CRC from non-CRC [AUC: 0.860 (95% CI 0.81-0,90), p-value=.0001].

With a cut-off of 3.04, cfDNA tumor-related (ALU247) showed a sensitivity of 77.94 (95% CI 70.0-84.6) and a specificity of 82.28 (95% CI 72.1-90.0) in distinguishing patients with CRC from non-CRC [AUC: 0.864 (95% CI 0.81-0,91), p-value=.0001].

CONCLUSIONS: Both ALU115 and ALU 247 fragments of circulating cfDNA seem promising non-invasive molecular markers of detection and progression of CRC.

The findings of the current study require to be confirmed on larger cohorts of patients with CRC and colonic adenoma.

[Title] A comparison of magnifying chromoendoscopy versus histopathology of forceps biopsy specimen in the diagnosis of minute flat adenoma of the colon.

Having noted a discrepancy between endoscopic and histopathological diagnoses in cases of minute adenomas of the colon, a prospective study was designed to clarify which is appropriate, magnifying chromoendoscopy or histopathology of a specimen obtained by biopsy forceps.

Comparison of the initial diagnoses between groups A and B showed that a total of 84.6% (88/104) of the lesions were diagnosed to be tubular adenomas histopathologically in group A, compared with 100% (104/104) in group B (P < 0.0001).

Results for comparison of the secondary diagnoses between group A and group B showed that 14 of the 16 lesions were diagnosed as tubular adenomas histopathologically.

Thereafter, 98.1% (102/104) of the lesions were diagnosed to be tubular adenomas histopathologically in group A (P = 0.4976).

In conclusion, high-resolution magnifying chromoendoscopy is an appropriate procedure for the diagnosis of minute adenomas in comparison with histopathology of specimens obtained by biopsy forceps in this prospective study.

[Title] [Expression of MMP-2, HIF-1alpha and VEGF in colon adenoma and colon cancer].

BACKGROUND/AIMS: This study was aimed to investigate the expression of matrix metalloproteinase-2 (MMP-2), hypoxia-inducible factor (HIF)-1alpha, and vascular endothelial growth factor (VEGF) in colonic adenoma-carcinoma sequence.

METHODS: Thirty-two tissue samples of colon adenoma, 11 of early colon cancer and 36 of advanced colon cancer were collected by colonoscopic biopsy.

Normal colonic tissues were also collected from the same subjects.

RESULTS: The expression level of MMP-2 mRNA showed a progressive increase in the advance of the colorectal adenoma-carcinoma sequence (p<0.05).

In colon cancer tissues, the expression level of MMP-2 mRNA showed an increasing trend according to differentiation, lymphatic invasion and Dukes' stage (p<0.05).

The mRNA expression levels of HIF-1alpha and VEGF were greater in tissues of early and advanced colon cancer compared with colon adenoma (p<0.05; p<0.001).

CONCLUSIONS: MMP-2, HIF-1alpha, and VEGF may be useful in detecting early carcinogenesis and progression of colon cancer.

[Title] [Colon adenoma detection using Kubelka-Munk spectral function of DNA and protein bands].

Differential diagnosis of human colon adenoma was studied using the Kubelka-Munk spectral function of the DNA and protein absorption bands at 260 and 280 nm in vitro.

The results of measurement showed that for the spectral range from 590 to 1 064 nm pathological changes of colon epithelial tissues were induced so that there were significant differences in the averaged values of the Kubelka-Munk function f(r infinity) and logarithmic Kubelka-Munk function log [f(r infinity)] of the DNA absorption bands at 260 nm between normal and adenomatous colon epithelial tissues, and the differences were 218% (p < 0.05) and 68.5% (p < 0.05) respectively.

Pathological changes of colon epithelial tissues were induced so that there were significant differences in the averaged values of the Kubelka-Munk function f(r infinity) and logarithmic Kubelka-Munk function log [f(r infinity)] of the protein absorption bands at 280 nm between normal and adenomatous colon epithelial tissues, and the differences were 208% (p < 0.05) and 59.0% (p < 0.05) respectively.

Pathological changes of colon epithelial tissues were induced so that there were significant differences in the averaged values of the Kubelka-Munk function f(r infinity) and logarithmic Kubelka-Munk function log [f(r infinity)] of the beta-carotene absorption bands at 480 nm between normal and adenomatous colon epithelial tissues, and the differences were 41.7% (p < 0.05) and 32.9% (p < 0.05) respectively.

Obviously, pathological changes of colon epithelial tissues were induced so that there were significant changes in the contents of the DNA, protein and beta-carotene of colon epithelial tissues.

The conclusion can be applied to rapid, low-cost and noninvasive optical biopsy of colon adenoma, and provides a useful reference.

[Title] Pseudoinvasion in an adenomatous polyp of the colon mimicking invasive colon cancer.

Pseudoinvasion or pseudocarcinomatous invasion in an adenomatous polyp of the colon can be unfamiliar to an endoscopist.

Pseudoinvasion in an adenomatous polyp represents prolapse of the adenomatous epithelium into its stalk.

In most cases its morphology does not differ from of general adenomatous polyps, but in some cases it can morphologically mimic a malignant polyp with submucosal invasion due to mass-like lesioning of its stalk.

This makes it difficult for endoscopists to differentiate pseudoinvasion in an adenoma from an invasive carcinoma by conventional endoscopy; instead, endoscopic ultrasonography can provide useful information for differentiating these conditions.

We report on an 82-year-old man who presented with a large pedunculated polyp with a thick stalk in the sigmoid colon, which mimicked a submucosal invasive carcinoma.

The patient was diagnosed with pseudoinvasion in an adenomatous polyp after segmental resection of the sigmoid colon.

[Title] Long-term use of progestogens: colon adenoma and colon carcinoma.

Colon cancer is the second most common cancer in women in the Western world and there is a trend towards an increasing risk.

Colon adenoma is a potential precursor for colon cancer.

Adenoma and carcinoma of the colon seem to be influenced by estrogens and progesterone/progestins.

This is related to the presence of estrogen and progesterone receptors, with apparently higher concentrations in colon cancers than in adenomas.

Epidemiological data and the finding of a significant reduction in colon cancer risk related to hormone replacement therapy (HRT), and in particular the length of HRT intake, indicate that progesterone/progestins have a preventive effect.

Furthermore, the recurrence rate of adenoma appears to be reduced, and the survival of colon cancer patients improved, with HRT; such effects have not been documented with ERT.

[Title] An association between obesity and the prevalence of colonic adenoma according to age and gender.

BACKGROUND: Epidemiologic data on obesity as a risk factor for colonic adenoma with respect to gender have not yet been confirmed.

Here, we aimed to compare the prevalence of colonic adenoma and of advanced polyps in age-stratified men and women at baseline, to examine the role of body mass index (BMI) on colonic adenoma risk according to age and gender, and to examine the influence of menopausal status.

BMI was assessed, and histology, size, and location of the adenoma were examined for each patient.

RESULTS: A significant increase in the prevalence of colonic adenoma and of advanced polyps was found to occur with age (P for trend < 0.01).

The prevalences of adenoma and advanced polyps were higher in men in most age groups (P < 0.01), but no significant difference in prevalences was observed between genderes in patients 70 years of age or older.

Moreover, a positive association between BMI and the prevalence of colonic adenoma and advanced polyps was shown in relatively young individuals of both gender (men in their thirties, P < 0.05; women in their forties, P < 0.05), and premenopausal women according to hormonal status (P = 0.01).

CONCLUSIONS: Our data suggest that obesity increases the risk of colonic adenoma in relatively young people and in premenopausal women subject to estrogen effects.

[Title] Decreased histamine catabolism in the colonic mucosa of patients with colonic adenoma.

INTRODUCTION: Alterations in mucosal histamine degradation play an important role in various gastrotinestinal diseases including colonic adenoma.

METHODS: About 94 colonic biopsies were endoscopically obtained from 23 patients suffering from colonic adenoma and 26 biopsies from six healthy individuals.

RESULTS: In adenoma patients DAO activities were slightly and HNMT activities were significantly decreased in normal mucosa compared to controls.

Activities of both enzymes were significantly lower in adenoma tissue than in healthy mucosa in the same patients.

Histamine concentrations were elevated in adenoma patients.

CONCLUSIONS: Histamine catabolism is decreased in the colonic mucosa of patients with colonic adenoma.

[Title] Association of the TCF7L2 polymorphism with colorectal cancer and adenoma risk.

We evaluated the association of a polymorphism in TCF7L2 (RS12255372) in the WNT signaling pathway, which previously has been strongly associated with risk of Type II Diabetes, with colorectal cancer (CRC) and adenoma in the prospective Nurses' Health Study (NHS) and Health Professionals Follow-up Study (HPFS) cohorts.

Hyperinsulinemia may be related to the risk of colon adenoma and cancer, therefore this variant associated with reduced insulin secretion would be predicted to be inversely associated with colorectal cancer.

[Title] Genetic polymorphisms in vitamin D receptor VDR/RXRA influence the likelihood of colon adenoma recurrence.

No gene-level associations were observed for VDR, nor was any single SNP in VDR related to any metachronous adenoma after correction for multiple comparisons.

Haplotypes within linkage blocks of RXRA support an approximately 30% reduction in odds of metachronous neoplasia arising in the proximal colon among carriers of specific haplotypes, which was strongest (OR(proximal), 0.67; 95% CI, 0.52-0.86) for carriers of a CGGGCA haplotype (rs1805352, rs3132297, rs3132296, rs3118529, rs3118536, and rs7861779).

[Title] Meat mutagens and risk of distal colon adenoma in a cohort of U.S. men.

We examined the association between intakes of the heterocyclic amines 2-amino-3,8-dimethylimidazo[4,5,-f]quinoxaline (MeIQx), 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), 2-amino-3,4,8-trimethylimidazo[4,5,-f]quinoxaline (DiMeIQx), and meat-derived mutagenicity (MDM) and risk of distal colon adenoma using a cooking method questionnaire administered in 1996 in the Health Professionals Follow-up Study cohort.

Between 1996 and 2002, 581 distal colon adenoma cases were identified.

Higher intake of MDM was marginally associated with increased risk of distal adenoma [fourth versus lowest quintile: odds ratio (OR), 1.39; 95% confidence interval (95% CI), 1.05-1.84; highest versus lowest quintile: OR, 1.29; 95% CI, 0.97-1.72; P(trend) = 0.08].

Our data also suggested a positive association between higher MeIQx (highest versus lowest quintile: OR, 1.28; 95% CI, 0.95-1.71; P(trend) = 0.22) and risk of adenoma, but this association was attenuated after adjusting for processed meat intake.

DiMeIQx and PhIP did not seem to be associated with risk of adenoma.

In conclusion, higher consumption of mutagens from meats cooked at higher temperature and longer duration may be associated with higher risk of distal colon adenoma independent of overall meat intake.

Because mutagens other than heterocyclic amines also contribute to MDM, our results suggest that mutagens other than heterocyclic amines in cooked meats may also play a role in increasing the risk of distal adenoma.

[Title] Nitric oxide impairs the 17beta-estradiol-induced apoptosis in human colon adenocarcinoma cells.

By contrast, E2 reduces the incidence of colon adenoma and carcinoma by about 30%.

We report the genomic and non-genomic E2-estrogen receptor (ER) beta-induced effects in human colon adenocarcinoma.

The E2-ERbeta-dependent gene transcription was inhibited by exogenous NO, whereas some non-genomic E2-dependent effects (e.g. p38/MAP kinase), important for the activation of the apoptotic cascade, were unaffected by NO.

However, NO impaired the E2-induced pro-apoptotic cascade in human colon adenocarcinoma cells by inhibiting caspase-3.

On the whole, high NO concentrations suppressed the E2 protective effects in the gastrointestinal tract, suggesting that the caspase-dependent apoptotic cascade may become critical under conditions of high redox stress such as occur under specific activation of the immune system by chronic infections or pathogen challenge.

[Title] Invasive carcinoma arising from a colonic adenoma with clear cell change.

Clear cell change (CCC) in colonic adenoma is rare, and its biological and clinical significance remains unknown.

Malignant progression of an adenoma with CCC has seldom been reported.

We report a case of a sigmoid adenoma with multiple foci of CCC associated with high-grade dysplasia and invasive carcinoma in a 62-year-old patient.

We evaluated the histochemical and immunohistochemical characteristics of each component of the adenoma.

In contrast to other parts of the adenoma, p53 was strongly and diffusely overexpressed in the areas of CCC, high-grade dysplasia, and carcinoma.

The MIB-1 labeling index was also significantly higher in these components than in other parts of the adenoma.

In conclusion, our findings suggest that CCC in adenoma may be associated with malignant progression of the adenoma.

Hence, for practical purposes, we recommend considering CCC in colonic adenomas as a high-grade dysplasia equivalent and following up the patient accordingly.

[Title] Oxidative stress and 8-oxoguanine repair are enhanced in colon adenoma and carcinoma patients.

Oxidative stress is involved in the pathogenesis of colon cancer.

In the examined groups of patients with colorectal cancer (CRC, n = 89), benign adenoma (AD, n = 77) and healthy volunteers (controls, n = 99), we measured: vitamins A, C and E in blood plasma, 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) and 8-oxo-7,8-dihydroguanine (8-oxoGua) in leukocytes and urine, leukocyte 8-oxoGua excision activity, mRNA levels of APE1, OGG1, 8-oxo-7,8-dihydrodeoxyguanosine 5'-triphosphate pyrophosphohydrolase (MTH1) and OGG1 polymorphism.

The vitamin levels decreased gradually in AD and CRC patients.

8-OxodG increased in leukocytes and urine of CRC and AD patients.

8-OxoGua excision was higher in CRC patients than in controls, in spite of higher frequency of the OGG1 Cys326Cys genotype, encoding a glycosylase with decreased activity. mRNA levels of OGG1 and APE1 increased in CRC and AD patients, which could explain increased 8-oxoGua excision rate in CRC patients.

The results suggest that oxidative stress occurs in CRC and AD individuals.

[Title] 18-Fluorodeoxyglucose positron emission tomography has limited sensitivity for colonic adenoma and early stage colon cancer.

BACKGROUND: 18-Fluorodeoxyglucose positron emission tomography (PET) is used clinically to detect recurrent colon cancer after surgical resection, but the sensitivity of PET for premalignant colon lesions and early stage colon cancer is not well defined.

METHODS: In a prospective study, 45 patients with a total of 58 colonic neoplasms, including premalignant polyps, premalignant, flat lesions, and early stage cancers, were evaluated by PET.

CONCLUSIONS: PET has limited sensitivity for flat, premalignant lesions; protruded, premalignant lesions smaller than 3 cm; and colon cancers smaller than 2 cm.

[Title] Decreased expression of cytochrome P450 protein in non-malignant colonic tissue of patients with colonic adenoma.

To estimate the role of cytochrome P450 in carcinogenesis of the colon, expression patterns and protein levels of four representative CYPs (CYP2C, CYP2E1, CYP3A4 and CYP3A5) were determined in colon mucosa of normal and adenomatous colonic tissue of patients with adenomas and disease-free controls.

METHODS: Expression of CYP2C, CYP2E1, CYP3A4, and CYP3A5 in colon mucosa of normal and adenomatous colonic tissue of patients with adenoma and disease-free controls was determined by RT-PCR.

RESULTS: With the exception of CYP3A5, expression of CYP mRNA was similar among groups and tissues (e.g. normal colon mucosa and adenoma).

CYP3A5 mRNA expression was significantly higher in adenoma in comparison to normal tissue of patients with adenoma (approximately 48%).

When comparing protein concentrations of CYPs measured in adenomas with neighboring normal colonic mucosa no differences were found.

However, in normal tissue of patients with adenomas, protein levels of CYP2C8, CYP3A4 and CYP3A5, but not that of CYP2E1, were significantly lower than in biopsies obtained from disease-free controls.

Specifically, in normal colonic mucosa of patients protein concentrations of CYP2C8, CYP3A4, and CYP3A5 were approximately 86%, approximately 69%, and approximately 54%, respectively, lower than in disease-free controls.

CYP2C8, CYP3A4 and CYP3A5) in colon mucosa might contribute to the development of neoplasia in the colon.

[Title] Global histone H4 acetylation and HDAC2 expression in colon adenoma and carcinoma.

Chromatin remodeling and activation of transcription are important aspects of gene regulation, but these often go awry in disease progression, including during colon cancer development.

We investigated the status of global histone acetylation (by measuring H3, H4 acetylation of lysine residues, which also occur over large regions of chromatin including coding regions and non-promoter sequences) and expression of histone deacetylase 2 (HDAC2) in colorectal cancer (CRC) tissue microarrays using immunohistochemical staining.

Specifically, HDAC2 and the acetylation of histones H4K12 and H3K18 were evaluated in 134 colonic adenomas, 55 moderate to well differentiated carcinomas, and 4 poorly differentiated carcinomas compared to matched normal tissue.

HDAC2 nuclear expression was detected at high levels in 81.9%, 62.1%, and 53.1% of CRC, adenomas, and normal tissue, respectively (P = 0.002).

HDAC2 expression was correlated significantly with progression of adenoma to carcinoma (P = 0.002), with a discriminative power of 0.74, when comparing cancer and non-cancer cases.

[Title] Over-expressed estrogen receptor-alpha up-regulates hTNF-alpha gene expression and down-regulates beta-catenin signaling activity to induce the apoptosis and inhibit proliferation of LoVo colon cancer cells.

Epidemiologic studies reported that the prevalence of hereditary non-polyposis colon cancer (HNPCC) in male is about 1.5-fold higher than that in female.

Patients that received E(2) replacement therapy were found to have a reduction in the incidence of colon adenoma and carcinoma.

[Title] An association between colonic adenoma and abdominal obesity: a cross-sectional study.

BACKGROUND: Colorectal adenoma is a precursor lesion of colorectal cancer and thus, it is an important target for preventing colorectal cancer.

Only a few studies suggest an association between colorectal adenoma and obesity, but results show considerable heterogeneity.

In this study, we investigated the association between colorectal adenoma and waist circumference.

METHODS: 165 adenoma cases and 365 polyp-free controls with a normal colon were compared in this cross-sectional study.

And smokers and men were more prevalent among cases than controls.Among the abdominal obese subjects, 45.6% had 1 or more adenoma, and 9.0% of these had advanced adenoma, whereas among subjects with a normal waist circumference, only 25.7% had 1 or more adenomas.

The prevalence of adenoma was higher among abdominal obese group (P < 0.05).

Logistic regression analysis showed that abdominal obesity was associated with an increased risk of colorectal adenoma (OR, 2.74; 95% CI, 1.66~4.51 in men, OR, 2.58; 95% CI, 1.08~6.12 in women).

While BMI was found to be weekly associated with the risk of adenoma among men at the highest BMI levels.

However, BMI was not associated with the risk for adenoma after adjusting for waist circumference.

CONCLUSION: Our data suggest that abdominal obesity is associated with an increased risk of colorectal adenoma.

[Title] Luminal histological outline and colonic adenoma phenotypes.

BACKGROUND: The luminal appearance of histological sections from colonic adenomas exhibits two different profiles: one regularly smooth and the other asymmetrically lumpy.

MATERIALS AND METHODS: For this purpose, the largest section of 107 consecutive endoscopically removed colonic adenomas was digitalized using an Epson Perfection 4990 PHOTO device.

RESULTS: Asymmetrically lumpy profiles were found in 96% (22/23) of the sections from adenomas measuring > or =15 mm, in 72% (39/54) of those having villous, mixed serrated or microtubular configurations and in 89% (24/27) showing carcinoma according to the Vienna classification.

CONCLUSION: The asymmetrically lumpy profile of sections from endoscopically excised colonic adenomas correlated with the size of the sections, the histological phenotype and the degree of neoplastic transformation.

Studies have been initiated to clinically explore whether the luminal configuration of colonic adenomas can be of help in predicting, before endoscopical removal, accepted histological parameters.

[Title] Functional expression of the interleukin-11 receptor alpha-chain in normal colonic epithelium and colon cancer.

The aim of this study was to investigate the expression profiling of IL-11Ralpha and its downstream signaling cascade in colonic adenoma and carcinoma.

MATERIALS AND METHODS: The expression of IL-11Ralpha in normal colonic mucosa, 11 colonic adenomas, and 10 carcinomas was analyzed by immunohistochemistry.

RESULTS: Immunohistochemistry revealed significant IL-11-Ralpha expression in epithelial cells of normal colonic mucosa.

In contrast, the expression of IL-11-Ralpha in colon adenomas and carcinomas was either absent or only detectable in very few scattered epithelial cells.

Densitometric analysis of Western blots confirmed these results, showing a decrease of IL-11Ralpha-protein in cells isolated from adenomas or carcinomas.

CONCLUSION: This study demonstrates a decrease of IL-11-Ralpha-protein expression in epithelial cells isolated from colon carcinomas and adenomas compared to normal colonic mucosa and a reduced STAT3 signaling.

[Title] [Bioinformatic analysis of adenoma-normal mucosa SSH library of colon].

We established a colonic adenoma-normal mucosa suppressive subtraction hybridization (SSH) library in 1999.

The nucleic acid analytical software, an integrator of the universal bioinformatics tools including phred, phd2fasta, cross_match, repeatmasker and blast2.0, can blast sequences of differential clones with the downloaded non-redundant nucleotide (NR) database.

Both genes were up-regulated in 10 or 9 out of 10 adenomas in comparison with the paired normal mucosa, respectively.

The candidate genes in A-N library would be of great significance in disclosing the molecular mechanism underlying in colonic adenoma initiation and progression.

[Title] A two-step model for colon adenoma initiation and progression caused by APC loss.

Aberrant Wnt/beta-catenin signaling following loss of the tumor suppressor adenomatous polyposis coli (APC) is thought to initiate colon adenoma formation.

These findings suggest that, following APC loss, CtBP1 contributes to adenoma initiation as a first step, whereas KRAS activation and beta-catenin nuclear localization promote adenoma progression to carcinomas as a second step.

Consistent with this model, human FAP adenomas showed robust upregulation of CtBP1 in the absence of detectable nuclear beta-catenin, whereas nuclear beta-catenin was detected in carcinomas.

[Title] Fas ligand expression in colon cancer: a possible mechanism of tumor immune privilege.

AIM: To detect the expression of Fas ligand (FasL) in colon cancer tissues and cell lines and analyze the function of FasL-expressing colon cancer cells in inducing Fas-sensitive T lymphocyte apoptosis.

METHODS: Ninety surgically resected colon cancer tissues and 15 hepatic metastasis specimens were investigated by immunohistochemical method with normal colon mucosa and colon adenoma as control.

FasL expression of 4 colon cancer cell lines, SW620, Lovo, LS-174T and SW1116, were detected by Western blotting assay.

The function of FasL expressed on colon cancer cells was determined by coculture assay with Jurkat T lymphocytes, the apoptotic rate of which was detected by flow cytometry assay.

RESULTS: Fifty-six (62.22%) cases of all the 90 colon cancer tissues and all (100%) the liver metastasis specimens expressed FasL, significantly higher than normal colon mucosa and colonic adenoma.

Higher expression of FasL was found in more advanced stage of colon cancer and in cancer tissues with lymphatic or hepatic metastasis.

All the colon cancer cell lines were found to express FasL.

CONCLUSION: The expression of FasL is upregulated in colon cancer and the functionally expressed FasL can induce apoptosis of Fas-expressing T lymphocytes.

[Title] Monocyte chemoattractant protein 1 and macrophage cyclooxygenase 2 expression in colonic adenoma.

BACKGROUND AND AIMS: Cyclooxygenase 2 (COX-2) expression in subepithelial macrophages of colorectal adenoma has been suggested as the first in a series of steps leading to colorectal tumorigenesis.

We tested the hypothesis that chemokines released from human colorectal adenoma epithelium might be involved in COX-2 expression in macrophages of the lamina propria.

METHODS: Endoscopic samples of sporadic colorectal adenomas were tested by enzyme linked immunosorbent assay for chemokines involved in macrophage chemotaxis.

Localisation of adenoma macrophage chemoattractant protein 1 (MCP-1) and COX-2 were determined by immunohistochemistry.

RESULTS: MCP-1 levels were markedly higher in adenoma with mild-moderate dysplasia (129.7 (19.9) pg/mg protein) and severe dysplasia (227.9 (35.4) pg/mg protein) than in normal colonic mucosa (55.8 (4.2) pg/mg protein).

Other chemokine levels, macrophage inflammatory proteins (MIP)-1alpha and MIP-1beta, and the chemokine regulated on activation of normal T cell expressed and secreted (RANTES) did not vary significantly between adenoma and normal mucosa.

MCP-1 levels in both adenoma and normal colonic mucosa increased significantly three hours after tissue cultivation in vitro.

MCP-1 immunoreactivity was restricted to the adenoma epithelium, with no reactivity seen in adjacent normal epithelial cells.

Addition of exogenous PGE(2) reversed this inhibitory effect on VEGF release, suggesting that MCP-1 in adenoma epithelial cells might be involved in COX-2 expression and subsequent macrophage activation.

CONCLUSIONS: MCP-1 in colorectal adenoma epithelial cells might be involved in macrophage migration and COX-2 expression, leading to the subsequent development of colonic adenoma.

[Title] [Endoscopic surveillance of colon-rectum in the narrow band imaging era].

[Transliterated title] Sorveglianza endoscopica del colon-retto. Ruolo del Narrow Band Imaging (NBI).

BACKGROUND AND AIMS: Colonoscopic surveillance is an established method of colorectal cancer (CRC) screening that reduces death rates, but has an adenoma miss rate of 10-20%.

Narrow band imaging (NBI), a novel endoscopic technology, highlights superficial mucosal capillaries and improves contrast for small adenomas.

This study evaluated the role of NBI in the improving colon adenoma detection.

PATIENTS AND METHODS: White light colonoscope was compared with NBI for adenoma detection during colonoscopy.

The outcome parameter was the difference in the adenoma detection rate between the two techniques.

All polyps detected were removed for histopathological analysis.

RESULTS: Adenomas were detected more frequently in the NBI group (51) than in the control group (49); however, the difference was not statistically significant (p = 0.128).

CONCLUSIONS: In our experience, the NBI did not increased the adenomas detection rate compared to white light by an endoscopist with a known high detection rate using white light.

[Title] Flat adenoma in colon: two decades of debate.

The existence of flat adenomas in the colon is well recognized.

Whether they represent a distinct disease with a pathogenetic pathway different from that of the classical adenoma-carcinoma sequence in colorectal tumorigenesis and have higher malignant potential remains a matter of debate.

To review the epidemiology, clinical features, detection and management of flat and depressed (non-polypoid) colonic neoplasm, we performed a thorough literature review on studies focusing on the prevalence, histological features, genetics, detection and treatment of flat and depressed (non-polypoid) colonic neoplasm.

A high percentage of severe dysplasia in flat colonic adenomas has not been consistently demonstrated.

Flat adenomas are found to have a lower incidence of major genetic abnormalities involved in the classical adenoma-carcinoma sequence and that has raised suspicions that they may have a different pathogenesis.

More advanced colonoscopic techniques, such as chromoendoscopy, may enhance the detection of small and inconspicuous colonic neoplastic lesions that lack a protruding configuration.

It is essential for endoscopists to appreciate the existence and clinical significance of flat and depressed colonic lesions as an important variant of colonic neoplasms so that the goal of reducing colorectal carcinoma incidence by polypectomy can be better achieved.

[Title] Hypertriglyceridemia is positively correlated with the development of colorectal tubular adenoma in Japanese men.

AIM: To determine the real association between serum lipid levels and colonic polyp formation.

METHODS: We performed a large scale retrospective study to analyze the correlation between the incidence of colorectal adenoma or carcinoma and the fasting serum levels of total cholesterol (TC) and triglycerides (TG) in patients who underwent total colonoscopy for screening for colon cancer.

RESULTS: Both levels were significantly elevated in patients with adenomas as compared with patients without any neoplastic lesion (TC 207.6+/-29.5 vs 199.5+/-34.3, n=4883, P<0.001; TG 135.0+/-82.2 vs 108.7+/-71.5, n=4874, P<0.001).

The difference was significant in patients with tubular adenoma but not in those with villous or serrated adenoma.

The level of TG in patients with invasive carcinoma did not show a significant elevation from that in patients with adenoma.

These findings suggest that hypertriglyceridemia is an independent risk factor for colonic adenoma in men.

[Title] [Identification of methylation related genes from laser capture microdissected colon samples during investigation of adenoma-carcinoma sequence].

[Transliterated title] Metilációs szabályozás alatt álló gének azonosítása lézerrel kimetszett vastagbéldaganat-sejtekben az adenoma-carcinoma sorrend vizsgálata során.

AIMS: Our aim was to identify colorectal cancer development and progression specific marker genes regulated by DNA methylation using gene expression analysis.

MATERIALS AND METHODS: Genes, which expression increased after the demethylation were determined in HT-29 colon adenocarcinoma cells treated with 10 microM 5-aza-2'-deoxycitidine.

In parallel, 5000 epithelial cells were collected with laser microdissection (LCM) from normal, adenoma and tumorous colonic samples.

The genes with gradually decreasing expression along the adenoma-carcinoma sequence were identified.

CONCLUSION: The regulation of the identified genes showing decreased expression during the adenoma-carcinoma sequence, can be associated with DNA methylation.

The identified genes showing colorectal cancer specific methylation pattern can be potential therapeutic targets in the future.

[Title] [Clinicopathologic study of colorectal polyps and obesity in Korean adult].

Numerous epidemiologic studies have shown a positive association between obesity and colorectal polyps.

There are few studies investigating the association between colorectal adenomatous polyps and body fat composition in Korea.

We tried to examine the relationship between body fatness and colorectal adenomatous polyps in health check-up subjects in Korea.

METHODS: Six thousand seven hundred and six routine health check-up subjects, who visited our hospital between March 2002 and April 2005 and underwent distal colon examimation with sigmoidoscopy, were enrolled in this study.

Among them, colonoscopy was done in 860 patients to evaluate the entire colon.

We tried to reveal the relationship between body mass index (BMI) and size, location, number and histopathological type of polyps.

RESULTS: The mean value of BMI in total polyp-free group (23.8+/-2.9) was not different from that of the polyp group (24.5+/-2.8, p=0.09).

The frequency of rectosigmoid polyps in obese patients (20.4%) was higher than that in non-obese patients (16.0%, p<0.05).

The frequency of adenomatous polyp was not different between obese and non-obese group.

Number of polyps (> or=4) correlated well with obesity.

Moreover, age and triglyceride level in patients with colonic adenoma were significantly higher than in patients without colonic adenom.

CONCLUSIONS: This study shows that obesity is not associated with colonic adenomatous polyp in Korean population.

However, we observed that obesity may be associated with rectosigmoid colon polyps.

Furthermore, age and triglyceride level might be the risk factors of colonic adenomatous polyps in Korean population.

This study was conducted to explore the relationship between serum transferrin saturation (as iron is a potential carcinogen) and presence of colon adenomas.

This may aid to evolve better colon cancer screening guidelines.

The adjusted odds ratio, derived from multiple logistic regression analysis, was used to measure the association between transferrin saturation and colon adenomas.

The adjusted odds ratio, for predicting the presence of polyp in those patients with transferrin saturation above the median was 10.9 (CI 4.0-29.5, P<0.001).

A one percent increase in transferrin saturation was associated with a 1.07 increase the odds of adenoma (CI 1.03-1.11, P<0.001).

CONCLUSIONS: Iron levels are directly linked to presence of colon polyps, and might help in evolving better screening guidelines.

[Title] Increased pulse wave velocity reflecting arterial stiffness in patients with colorectal adenomas.

The obese patients with diabetes or cardiovascular risk factors are associated with increased risk of colorectal cancer as well as adenomas under the shared pathogenesis related to atherosclerosis.

Here we determined the association between increased arterial stiffness and colorectal adenomas incorporating parameters including age, gender, waist circumference, body mass index, lipid profiles, fasting glucose, and blood pressure.

Subjects who simultaneously underwent colonoscopies and pulse wave velocity (PWV) determinations between July 2005 and September 2006 were analyzed, based on which the subjects were classified into two groups as patients group with colorectal adenomas (n = 49) and control group (n = 200) with normal, non-polypoid benign lesions or hyperplastic polyps.

Uni- and multi-variate analyses were performed to calculate the odd ratio for colon adenomas.

Based on uni-variate analysis, age, waist circumference, body mass index, heart-femoral PWV (hfPWV), and brachial-ankle PWV were significantly associated with adenomas (p<0.05) and multiple logistic regression analysis showed that the heart-femoral PWV, waist circumference, and the levels of LDL-C were significant risk factor for colorectal adenoma.

However, arterial stiffness did not affect the progression of colon adenoma.

The finding that hfPWV, reflecting aortic stiffness, was increased in patients with colorectal adenomas lead to conclusion that patients who have prominently increased arterial stiffness can be recommended to undergo colonoscopic examinations and at the same time we also recommend counseling about the risk for atherosclerosis in those who have colorectal adenomas.

[Title] The size of colon polyps revisited: intra- and inter-observer variations.

BACKGROUND: It has been postulated that the occurrence of invasive carcinoma in a colon adenoma can be predicted by estimating the size of the resected polyp.

Recently, significant intra- and inter-observer differences in size were found when 22 pathologists estimated the size of 12 polyp phantoms.

In this work, the size of a large cohort of endoscopically-resected colon polyps was assessed with a novel method.

PATIENTS AND METHODS: Three pathologists measured photocopies of 148 resected polyps (adenomas at histology) in two independent trials.

When 6 possible combinations (the 3 size limits proposed for predicting cancer risk in adenomas, and 2 different trials) were tested for the 13 adenomas showing invasive carcinoma, merely one of the three participants recorded the same size, but only in 11% of the 6 possible combinations.

CONCLUSION: Present and previous investigations indicate that the lack of reproducibility makes the use of size limits in predicting cancer risk in polyps removed at colonoscopy unreliable.

[Title] Chemopreventive efficacy of naproxen and nitric oxide-naproxen in rodent models of colon, urinary bladder, and mammary cancers.

Nonsteroidal anti-inflammatory drugs (NSAID) have been highly effective in preventing colon, urinary bladder, and skin cancer preclinically, and also in clinical trials of colon adenoma formation.

In the azoxymethane-induced rat colon aberrant crypt foci (ACF) model, naproxen administered at 200 and 400 ppm in the diet reduced mean ACFs in the colon by about 45% to 60%, respectively.

These data show that both naproxen and NO-naproxen are effective agents against urinary bladder and colon, but not mammary, carcinogenesis.

[Title] GSTM1, GSTT1, and GSTP1 polymorphisms and risk of advanced colorectal adenoma.

Cigarette smoking is a risk factor for colon adenoma.

We examined the prevalence of GSTM1 and GSTT1 gene deletions, and two GSTP1 polymorphisms in 772 cases with advanced colorectal adenomas (>1 cm, villous elements or high-grade dysplasia) of the distal colon (descending or sigmoid colon or rectum) and 777 sigmoidoscopy negative controls enrolled in the screening arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial.

Advanced adenoma risk was increased in current/former smokers (OR, 1.4; 95% CI, 1.2-1.8).

In summary, this is the first study to report associations between colorectal adenomas and GSTM1 wild-type and GSTT1 null allele among smokers.

[Title] Different expression of calgizzarin (S100A11) in normal colonic epithelium, adenoma and colorectal carcinoma.

The aim of the study was to detect proteomic markers usable to distinguish colorectal carcinoma from colon adenoma for a better understanding of the molecular mechanisms in the process of tumourigenesis.

Therefore, we microdissected colon carcinoma tissue, epithelial colon adenoma tissue as well as normal adjacent colon epithelium and determined protein profiles by SELDI-TOF MS.

For their identification colon biopsis were lysed and subjected to a two-dimensional gel electrophoresis for separation.

[Title] A possible new syndrome with growth-hormone secreting pituitary adenoma, colonic polyposis, lipomatosis, lentigines and renal carcinoma in association with familial testicular germ cell malignancy: A case report.

BACKGROUND: Germ-cell testicular cancer has not been definitively linked to any known hereditary cancer susceptibility disorder.

His evaluation as part of an etiologic study of familial testicular cancer revealed multiple colon polyps (adenomatous, hyperplastic, and hamartomatous) first found in his 50 s, multiple lipomas, multiple hyperpigmented skin lesions, left kidney cancer diagnosed at age 64, and a growth-hormone producing pituitary adenoma with associated acromegaly diagnosed at age 64.

Alternatively, this family's phenotype might represent a novel neoplasm susceptibility disorder.
