The BRAF gene is mutated in 4% to 12% of unselected colorectal cancers, particularly those with high microsatellite instability and in premalignant lesions, such as serrated adenomas and hyperplastic polyps.

To evaluate the role of oncogenic BRAF mutations in non-hereditary nonpolyposis colorectal cancer/non-familial adenomatous polyposis familial colorectal cancer, we did a mutation screening of the most common BRAF mutation, the V600E mutation, in 194 colorectal tumors from patients with a positive family history of the disease.

Interestingly, families with extracolonic tumors showed a much higher mutation frequency (17.5%) compared with families with colonic cancer only (3.5%; P = 0.009).

Subjects from families where the V600E mutation was identified had less adenomas compared with those from families where no BRAF mutation had been found (odds ratio, 8.5; 95% confidence interval, 1.1-64.6).

These findings indicate that adenomas might be less important in the cancer development in the group of families with BRAF-V600E mutations and indirectly support a previous hypothesis that tumors might develop through the hyperplastic polyp-serrated adenoma pathway.

DATA SYNTHESIS: Regular use of aspirin reduced the incidence of colonic adenomas in RCTs (relative risk [RR], 0.82 [95% CI, 0.7 to 0.95]), case-control studies (RR, 0.87 [CI, 0.77 to 0.98]), and cohort studies (RR, 0.72 [CI, 0.61 to 0.85]).

CONCLUSIONS: Aspirin appears to be effective at reducing the incidence of colonic adenoma and colorectal cancer, especially if used in high doses for more than 10 years.

[Title] Non-steroidal anti-inflammatory drug use and colorectal polyps in the Prostate, Lung, Colorectal, And Ovarian Cancer Screening Trial.

OBJECTIVES: Non-steroidal anti-inflammatory drugs (NSAIDs) have been documented in animal and human studies to reduce risk for colorectal cancer and adenomatous polyps, but risk modification for subgroups of the population and effects on hyperplastic polyps have been less studied.

Follow-up of detected polyps was accomplished outside the Trial setting and relevant records were sought and abstracted.

Cases (n=4,017) included subjects with a biopsy-proven polyp in the left side of the colon (descending colon, sigmoid, and rectum) detected as a consequence of PLCO screening; controls (n=38,396) were subjects with no left-sided colon polyp.

RESULTS: Regular use of aspirin (≥ 4 times/month) in the past year was inversely associated with hyperplastic polyps (odds ratios (OR)=0.8, 95% confidence interval (CI)=0.7-0.9), adenomatous polyps (OR=0.8, 95% CI=0.8-0.9), and advanced adenomas (OR=0.8, 95% CI=0.7-0.9).

As frequency of aspirin use increased, the prevalence of polyps decreased significantly for each histological classification (P for trend ≤ 0.0004).

Similar patterns were found for adenomas and ibuprofen.

Overall protection was consistent in both the descending colon or sigmoid and the rectum, but more evident in males.

CONCLUSIONS: This study of a large general risk population supports previous work that recent use of aspirin and ibuprofen is associated with a decreased risk of colorectal adenomas and demonstrates that this protective effect may be stronger in certain population subgroups and is also evident for aspirin and hyperplastic polyps.

The senescence-associated signature of p53 isoform expression (that is, elevated p53beta and reduced Delta133p53) was observed in vivo in colon adenomas with senescent phenotypes.

The increased Delta133p53 and decreased p53beta isoform expression found in colon carcinoma may signal an escape from the senescence barrier during the progression from adenoma to carcinoma.

[Title] Mucins in the colorectal neoplastic spectrum with reference to conventional and serrated adenomas.

BACKGROUND/AIMS: Alterations in expression of mucins and aberrant expression of various types of mucin genes were observed in colorectal adenomas and carcinomas, though their significance in neoplastic transformation of colorectal epithelium is yet to be determined.

The aim of this study was to determine expression of MUC1, MUC2, MUC5AC, and MUC6 through conventional adenoma-carcinoma sequence and polyps involved in the "serrated" pathway of the colorectum using tissue array technique.

METHODS: In this study, a total of 172 cases including 100 colorectal polyps [8 hyperplastic polyps, 10 sessile serrated adenomas, 19 tubular, 37 tubulovillous, and 26 villous adenomas], 16 adenomas with intramucosal carcinoma, 28 conventional colorectal cancers, and 28 normal mucosae were examined.

Sessile serrated adenomas exhibited the highest MUC5AC expression while adenomatous polyps showed an increase in MUC5AC expression in parallel with neoplastic progression (p<0.001).

Hyperplastic polyps seemed to lie between normal mucosa and sessile serrated adenomas in terms of mucin expression, suggesting that they are morphologically and histogenetically linked.

CONCLUSIONS: Upregulation of MUC1 and MUC6 through the adenoma-carcinoma sequence together with downregulation of MUC2 and MUC5AC at the neoplastic end of the spectrum seem to follow the steps of malignant transformation.

[Title] Tubulo-villous adenoma of the vagina.

BACKGROUND: Tubulo-villous adenomas are common in the colon and rectum, but extremely rare in the vagina.

As far as we know, only two cases of tubulo-villous adenoma have ever been reported.

We report the third case of enteric-type tubulo-villous adenoma of the vagina.

The tumor was excised and pathologically confirmed as a tubulo-villous adenoma.

CONCLUSION: Because some tubulo-villous adenomas in the colon and rectum can progress to the cancer, this case requires long-term follow-up to detect recurrence and malignant transformation.

Adenomatous polyps are the most common neoplastic findings uncovered in people who undergo colorectal screening or have a diagnostic workup for symptoms.

It was common practice in the 1970s for these patients to have annual follow-up surveillance examinations to detect additional new adenomas as well as missed synchronous adenomas.

As a result of the National Polyp Study report in 1993, which demonstrated clearly in a randomized design that the first postpolypectomy examination could be deferred for 3 years, guidelines published by a gastrointestinal consortium in 1997 recommended that the first follow-up surveillance be 3 years after polypectomy for most patients.

In 2003, these guidelines were updated, colonoscopy was recommended as the only follow-up examination, and stratification at baseline into lower and higher risk for subsequent adenomas was suggested.

In the present paper, a careful analytic approach was designed addressing all evidence available in the literature to delineate predictors of advanced pathology, both cancer and advanced adenomas, so that patients can be more definitely stratified at their baseline colonoscopy into those at lower or increased risk for a subsequent advanced neoplasia.

People at increased risk have either three or more adenomas, or high-grade dysplasia, or villous features, or an adenoma > or =1 cm in size.

People at lower risk who have one or two small (< 1 cm) tubular adenomas with no high-grade dysplasia can have a follow-up in 5 to 10 years, whereas people with hyperplastic polyps only should have a 10-year follow-up as average-risk people.

It has been shown that the first screening colonoscopy and polypectomy produces the greatest effects on reducing the incidence of colorectal cancer in patients with adenomatous polyps.

[Title] CYP27A1 and CYP24 expression as a function of malignant transformation in the colon.

However, vitamin D precursors do not present toxicity concerns and may be sufficient for CRC chemoprevention or chemotherapy, providing the appropriate enzymes are present in colonic epithelia.

We previously showed that CYP27B1 is present at equally high levels in the colon and CRC irrespective of differentiation but was not present in metastases.

In this study we used quantitative immunohistochemistry to show that CYP27A1, converting D3 to 25-hydroxycholecalciferol, is present in increasing concentrations in the nuclei of normal colonic epithelia, aberrant crypt foci (ACF), and adenomatous polyps.

Similarly, increasing amounts of the deactivating enzyme CYP24 are present in the nuclei of normal colonic epithelia, ACFs, and adenomatous polyps.

These data indicate that non-toxic vitamin D precursors should be sufficient for CRC chemoprevention, but that neither vitamin D nor its precursors may be sufficient for CRC chemotherapy.

Herein, we describe the clinical, pathologic, immunohistochemical, and molecular features of 3 unique patients with long standing inflammatory bowel disease, all of whom developed numerous discrete hyperplastic/serrated colonic polyps similar to those described in the hyperplastic/serrated polyposis syndrome.

The 3 patients (2 with ulcerative colitis and 1 with Crohn ileo-colitis) were evaluated for a variety of clinical, histologic (including the type, location and number of polyps in the colon), and immunohistochemical features [MLH-1, MSH-2, MGMT (O(6)-methylguanine-DNA methyltransferase), beta-catenin, and p53].

KRAS and BRAF mutation analysis was also performed on a subset of polyps from 2 patients.

All patients had moderate-severe pancolitis of more than 10 years duration and had >20 colonic polyps.

None had polyps in the upper gastrointestinal tract.

Pathologically, a combination of conventional hyperplastic polyps and sessile serrated polyps (adenomas) were present in the 3 cases.

In addition, serrated adenomas were present in 2 and conventional adenomas in 1.

However, 2 cases showed loss of MGMT in several serrated polyps, and one also in adjacent colitic mucosa.

KRAS mutations were detected in 5/11 serrated polyps.

However, BRAF mutations were not present in any of the polyps tested.

[Title] Noninvasive detection of candidate molecular biomarkers in subjects with a history of insulin resistance and colorectal adenomas.

We have developed novel molecular methods using a stool sample, which contains intact sloughed colon cells, to quantify colonic gene expression profiles.

For this purpose, the effects of a legume-enriched, low glycemic index, high fermentable fiber diet was evaluated in subjects with four possible combinations of risk factors, including insulin resistance and a history of adenomatous polyps.

Linear discriminant analysis was successfully used to identify the best single genes and two- to three-gene combinations for distinguishing subjects with insulin resistance, a history of polyps, or exposure to a chemoprotective legume-rich diet.

These results support our premise that gene products (RNA) isolated from stool have diagnostic value in terms of assessing colon cancer risk.

[Title] [Clinical aspects in polyps of the colon].

[Transliterated title] Aspectos clínicos de los pólipos colónicos.

INTRODUCTION: The colonics polyps according to their number, size, location, age of presentation and mainly, according to their histology, have the potentiality of malignant degeneration, which makes of a continuous study and pursuit susceptible.

OBJECTIVES: To evaluate the relation between the histologic type of the colon polyps, its location, the degree of dysplasia, the size, its possible commitment by carcinoma, the age, sex and the handling that has occurred them, in a series of 684 patients of the National Institute of Enfermedades Neoplásicas (INEN) between the 1 of January from 1974 to the 31 of March of the 2004.

MATERIAL AND METHODS: The revision of clinical histories of 840 patients with the diagnosis of colon polyp was made who attended the service of Gastroenterology of the INEN between the 1 of January from 1974 to the 31 of March of 2004 and a card predesigned for each clinical history filled.

1162 resecteds polyps evaluated themselves in this period.

The final sample was of 684 patients, in whom it was 1057 polyps.

Other endoscopic findings were: internal hemorrhoids (172), colonic diverticulosis (50), anal fissure (4), and nonspecific ulcerative colitis (2).

RESULTS: 1057 polyps extirpated, by means of the endoscopy polipectomy were 1016, with colectomy were 32 and with transanal resection without colectomy they 9.

Within the histology of the 1057 polyps, 331 was briefed (31.3%) that were hyperplasic, 448 (42.4%) adenomas, 278 (26.3%) others and 35 (8.2%) adenocarcinomas on adenomas.

The location but frequence of the adenomas was in the left colon (76.6%).

Adenocarcinoma (carcinomas on adenomas), was present mainly in polyps villous type, with dysplasia severe and greater to 10 mm.

Nevertheless, in smaller polyps of 5mm with dysplasia severe, was a polyp invaded by cancer, that represents the 0,8% of millimetric polyps.

The made handling was mainly endoscopic, with 96% of the resected polyps this way, also slogan transanal resection and segmental colonic resection.

The colectomy was necessary in 3% of all the made interventions, dysplasia severe or carcinoma was made in adenomatous polyps with, and in greater percentage in greater polyps of 20 mm (53%).

On the other hand, in polyps with level of invasion Haggitt 3 and 4, the colectomy was the election treatment.

CONCLUSIONS: The Evaluation of colonic polyps in INEN is predominantly by endoscopy.

The polyps are more frequent over the 50 years and have preferred location in the left colon.

The carcinoma is more probable with severe dysplasia and greater size of the adenoma.

All polyps, from the millimetric ones, including the hyperplasic, must be considered marks of neoplasia and extirpated in its totality.

[Title] A case of primary squamous cell colon cancer.

Carcinomas of the colon are a common cancer seen in both inpatient and outpatient settings with approximately 145,000 new cases being diagnosed every year in the USA.

Despite the frequency of these cancers being seen, it continues to be a rarity to see a primary squamous cell cancer of the colon.

While the exact aetiology of this rare tumour is currently still not completely understood, various aetiologies include chronic irritation leading to squamous differentiation, embryonic migration of ectodermal cells to the colon, or adenomas undergoing squamous transformation.

[Title] Pigmented mesenteric lymphadenopathy in familial adenomatous polyposis - an unusual cause of intraoperative abandonment of ileo-anal pouch.

Familial adenomatous polyposis (FAP) is an autosomal dominant condition with near complete penetrance, characterised by the presence of numerous adenomatous polyps of the colon and rectum.

Melanosis coli describes the brownish-black discolouration of the colon resulting from the accumulation of a granular pigment in the phagosomes of macrophages in the colonic lamina propria.

The presence of melanosis pigment in pericolonic lymph nodes has been reported in patients with coincidental melanosis coli, following segmental colonic resection.

Gardner syndrome is a variant of familial adenomatous polyposis (FAP) and results in the manifestation of numerous external and internal symptoms including gastrointestinal polyps, osteomas, tumors, and epidermoid cysts.

Stemming from a mutation in the adenomatous polyposis coli (APC) gene, Gardner syndrome shares genetic correlations with the FAP phenotype; as a result, it becomes all the more crucial for physicians to be able to discern Gardner syndrome from other differential diagnoses such as Turcot syndrome, FAP, and other attenuated forms of familial polyposis.

Fortunately, Gardner syndrome has characteristic polyps in the colon, osteomas, and also exhibits abnormalities in the retinal epithelium that discern it from others.

Surgery is the most effective method of management for Gardner syndrome; restorative proctocolectomy with ileal pouch anal anastomosis with mucosectomy is the top choice for colonic malignancies, and skin manifestations can be treated through a variety of excisions and therapy depending on location, size, and number of malignancies.

Currently, there are no specific screening recommendations for Gardner syndrome, but testing following general screening recommendations for extra-colonic malignancies, genetic counseling, and endoscopy are encouraged.

[Title] Promoter methylation status of the MGMT, hMLH1, and CDKN2A/p16 genes in non-neoplastic mucosa of patients with and without colorectal adenomas.

CpG island methylation has been observed in aberrant crypt foci (ACF) and adenomas in the colon, implicating it in the earliest aspects of colon cancer formation.

In addition, some investigators have identified an age-related increase in DNA methylation of the ESR1 locus in the colon mucosa, suggesting that DNA methylation may be a pre-neoplastic change that increases the risk of colon adenomas and colon cancer.

We investigated the methylation status in the promoter regions of the CDKN2A/p16, hMLH1, and MGMT genes in human non-neoplastic rectal mucosa and evaluated whether these methylation markers may predict the presence of adenomatous polyps in the colon.

The promoter methylation patterns of these genes were examined in rectal biopsies (mucosa samples) of 97 colorectal adenoma cases and 94 healthy controls using methylation-specific PCR (MSP) assays.

The methylation status of these genes in rectal mucosa biopsies detected by MSP assays may not distinguish between patients with and without adenomas in the colon.

[Title] Serrated adenoma is a risk factor for subsequent adenomatous polyps.

BACKGROUND: Serrated adenomas (SA) are histologically defined by the presence of both hyperplastic and adenomatous features.

These uncommon polyps are thought to play an important role in the development of sporadic colorectal cancers (CRC) with microsatellite instability (MSI).

This study was undertaken to define the relationship between SA and the future development of adenomatous polyps.

These were matched to controls by age, sex, indication for colonoscopy, polyp type and number and duration of follow-up.

Of these, 80 patients (0.5%) with SA were found, and of these SA, 80% were found in the left colon.

On follow-up examination four patients (24%) and no controls had adenomatous polyps (P = 0.01).

Serrated adenomas appear to be found more commonly in the left colon and in older patients.

This study found a significant association between SA and the subsequent development of adenomatous polyps.

[Transliterated title] Precisión diagnóstica de la calprotectina fecal para predecir una colonoscopia patológica.

The colonoscopy is the gold standard method of detecting an organic pathology in the colon.

Fecal calprotectin (FCP) is a marker that may detect organic pathologies of the colon.

People were divided in: normal colonoscopy: 117 people, and 28 colon adenomas, 20 colorectal cancer (CRC) and 25 IBD.

217 mg/kg was the best cut-off for discriminating patients with organic colon disorders.

The measurement of FCP is a non-invasive, inexpensive, reliable and easily measured test.

[Title] Sporadic adenomatous polyp regression with exisulind is effective but toxic: a randomised, double blind, placebo controlled, dose-response study.

The aim of our study was to investigate if exisulind induces regression of sporadic colonic adenomas.

At baseline colonoscopy, left sided polyps (3-10 mm) were tattooed, measured, and left in place.

Follow up sigmoidoscopy was performed after six months, and removal of any remaining polyps at the 12 month colonoscopy.

The primary efficacy variable was change in polyp size from baseline.

The decrease in median polyp size was significantly greater (p=0.03) in patients who received exisulind 400 mg (-10 mm2) compared with those who received placebo (-4 mm2).

CONCLUSION: Exisulind caused significant regression of sporadic adenomatous polyps but was associated with more toxicity.

This model of polyp regression, short in its term and involving a comparatively small patient sample size, may be the best available tool to assess a therapeutic regimen before launching into large preventive clinical studies.

[Title] Colorectal polyps on portal phase contrast-enhanced CT colonography: lesion attenuation and distinction from tagged feces.

OBJECTIVE: The purpose of our study was to determine the attenuation of colorectal polyps on portal phase contrast-enhanced CT colonography (CTC) and evaluate whether enhanced polyps can be clearly distinguished from tagged feces during CTC review.

Forty-eight colonoscopy-proven polyps (6-20 mm) and 41 polypoid tagged feces (6-19 mm) were selected from contrast-enhanced CTC performed without (n = 37 examinations) and with (n = 10 examinations) fecal tagging, respectively.

Attenuation of the polyps and tagged feces was measured.

Four independent blinded radiologists reviewed the polyps and tagged feces at both wide (width, 1,500 H; level -400 H) and soft-tissue (width, 400 H; level, 20 H) window settings to distinguish them by using subjective visual assessment.

RESULTS: Polyp attenuation on the portal phase was not correlated with size (R = -0.003; p = 0.99) and was not different between histologic types (p = 0.884).

Enhanced polyps (mean +/- SD, 119.9 +/- 25.3 H; range, 50-173 H) showed significantly lower attenuation than did tagged feces (1,521.4 +/- 683.6 H; range, 495-2,683 H) without any overlap (p < 0.0005).

An 8-mm sessile adenomatous polyp was misinterpreted as tagged feces by one reviewer.

CONCLUSION: Polyp attenuation on portal phase contrast-enhanced CTC ranges from 50 to 173 H.

Contrast-enhanced polyps are clearly and consistently distinguished from barium-tagged polypoid feces.

We describe a 58-year-old woman who was incidentally found to have gastric and colonic polyposis, hypoalbuminemia, cutaneous hyperpigmentation and onychodystrophy (Cronkhite-Canada syndrome).

Histology of polyps from the stomach showed features of juvenile or retention type (hamartomatous) polyps with Helicobacter pylori (H. pylori) infection.

The large pedunculated colonic polyps showed hamartomatous polyps with adenomatous component and polypectomy was performed.

After the treatment with H. pylori eradication and omeprazole, the gastric polyposis, hypoalbuminemia and anemia regressed, and endoscopic polypectomy of gastric polyps were performed.

[Title] Reduction of miss rates of colonic adenomas by zoom chromoendoscopy.

BACKGROUND AND AIMS: The aim of this study was to determine the detection rate of polyps using zoom chromoendoscopy (ZE) compared with standard video colonoscopy.

The second colonoscopy (C2) was done with a zoom colonoscope spraying the whole colon with indigocarmine (0.4%).

During C1, 56 lesions were detected in 26 of 50 patients (34 hyperplastic and 22 adenomatous).

During C2, 19 additional polyps were documented prior to ZE (15% tandem miss rate), and 20 further lesions were detected with ZE (21% additional polyp detection rate compared to C1 and C2 without ZE).

Of the 39 additional lesions removed during C2 after ZE, 29 were hyperplastic and 10 were adenomatous.

Most adenomas detected during the second investigation were found in patients in whom adenomatous polyps had already been removed during the initial colonoscopy (9 of 26 patients vs 1 of 24 patients, p<0.02).

The pit pattern classification allowed a correct differentiation between hyperplastic and adenomatous polyps (accuracy 93%, sensitivity 90%, specificity 97%).

CONCLUSION: Using zoom chromoendoscopy, the rate of detecting colonic polyps can be increased at the cost of a longer retrieval time.

CRC develops from benign adenomas in the colon over a long time.

RESULTS AND INTERPRETATION: Acetylsalicylic-acid, non-steroidal anti-inflammatory drugs and COX-2 inhibitors are shown to reduce adenoma growth, but it remains uncertain whether these drugs reduce the incidence of CRC.

We analyzed the DNA of various organs and lesions in Korean patients with Cowden syndrome, their family members, and patients with familial adenomatous polyposis for germline or somatic PTEN mutations.

METHODS: The 11 patients included in this study were 5 patients with Cowden syndrome, 4 of their family members, and 2 patients with familial adenomatous polyposis.

Deletions and mutations in exons 1 to 9 of the PTEN gene were evaluated by polymerase chain reaction-single strand conformation polymorphism and sequencing analysis in esophageal acanthosis, gastric polyps, colonic polyps, skin lesions, and peripheral blood mononuclear cells.

RESULTS: All patients with Cowden syndrome showed several to numerous polyps in the gastrointestinal tract.

Identical mutations were found in all tissue samples, including colonic polyps, from each patient.

No PTEN mutations were found in their family members or in any patient with familial adenomatous polyposis.

The Comet-FISH technique is a useful tool to detect overall and region-specific DNA damage and repair in individual cells.

Whereas the Comet assay allows separating fragmented from non-fragmented DNA, FISH helps to detect specifically labelled DNA sequences of interest, including whole chromosomes.

Thus the combination of both techniques has been applied in particular for detection of site-specific breaks in DNA regions which are relevant for development of different diseases.

This paper reviews the relevant literature and presents three examples on how Comet-FISH was used for studying the induction of DNA damage by genotoxic compounds related to oxidative stress in colon cancer-relevant genes (TP53, APC, KRAS) of a colon adenoma cell line.

A third example relates to measuring repair of specific gene regions using Comet-FISH, a method that can be developed to biomarker application.

Taken together, available data suggests that Comet-FISH helps to get further insights into sensitivity of specific DNA regions and consequently in mechanisms of carcinogenesis.

Although the nature of the measured Comet-FISH endpoint precludes us from stating basically that damage and repair are occurring within the specific gene, it is at least possible to evaluate whether the damage and repair are occurring within the vicinity of the gene of interest.

[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] Dose-dependent promoting effect of dextran sodium sulfate on mouse colon carcinogenesis initiated with azoxymethane.

We previously reported a powerful tumor-promoting ability of dextran sodium sulfate (DSS) in a novel mouse model for colitis-related colon carcinogenesis initiated with azoxymethane (AOM).

All animals were sacrificed at week 14 and histological alterations in their colon and nitrotyrosine immunohistochemistry were examined to evaluate the nitrosative stress.

In the mice which received AOM and 2% DSS, the incidences (multiplicity) of colonic tubular adenoma and adenocarcinoma were 75% (1.25+/-1.26/mouse) and 100% (2.75+/-2.22/mouse), respectively.

Mice given AOM and 1% DSS had 80% incidence of adenoma (1.00+/-0.71/mouse) and 60% incidence of adenocarcinoma (1.40+/-2.07/mouse) in the colon.

In a mouse treated with AOM and 0.5% DSS, only one colonic adenoma (20% incidence with 0.20+/-0.45 multiplicity) developed.

Higher frequency of high-grade colonic dysplasia was noted in mice given AOM and 2% or 1% DSS when compared with mice treated with AOM and lower doses of DSS.

Also, scoring of inflammation and nitrotyrosine immunoreactivity suggested that severe inflammation and nitrosation stress caused by high-doses (2% and 1%) of DSS contribute its tumor-promoting effects in mouse colon carcinogenesis initiated with a low dose of AOM.

[Title] Bile acid induced gene expression in LT97 colonic adenoma cells.

LT97 human colonic adenoma cells reflecting early premalignant genotype and growth characteristics have been posed to tumor promoting bile acids in order to identify marker genes that permit identification of tumor promoters in vitro.

Physiologically relevant concentrations of desoxycholate (DOC) and chenodesoxycholate (CDC) upregulated expression of c-fos and COX-2 in a concentration- and time-dependent manner.

Transient induction of c-fos was seen with the non-promoting taurodesoxycholate (TDOC) as well as DOC, however extended induction at 3 h was only achieved by DOC and CDC reaching 3-6-fold as compared to the control.

Stimulation of COX-2 expression was completely specific for the tumor promoting analogs DOC and CDC.

Expression of VEGF was stimulated 4-5-fold in the tumor promoter (DOC and CDC) groups and about 2-fold in the non-promoting controls TDOC and GCDC.

At later times the tumor promoter specific difference was lost.

Our results show that all three genes are modulated in a tumor promoter dependent way and that their upregulation in LT97 adenoma cells can be used for in vitro testing of colon tumor promoters and chemopreventive compounds.

[Title] [Emerging concepts in colorectal serrated polyps].

Colorectal serrated polyps are heterogeneous epithelial lesions characterized by a serrated architecture.

They include the classical hyperplastic polyps and the much rarer serrated adenomas and mixed polyps.

Whereas serrated adenomas are composed of an unequivocal adenomatous epithelium with architectural serrated, mixed polyps include two separate hyperplastic and adenomatous components.

During the past few years, another type of serrated polyp with only very subtle proliferation abnormalities has been described.

These atypical serrated polyps may occur either sporadically or in the context of colorectal polyposis.

Despite their close resemblance to traditional hyperplastic polyps, some authors argued that they should be regarded as authentically neoplastic lesions and have proposed to call them "sessile serrated adenomas".

This article reviews the histological features, the endoscopic appearance, the natural history and the molecular phenotype of the different categories of serrated polyps and introduces the concept of "serrated neoplastic pathway" in the development of colorectal cancer.

[Title] Noninvasive monitoring of colonic carcinogenesis: feasibility of [(18)F]FDG-PET in the azoxymethane model.

BACKGROUND: Azoxymethane (AOM) is a potent carcinogen that induces colorectal cancer and adenomas in rats.

At present, it is unknown at which stage FDG accumulation occurs during the adenoma carcinoma sequence.

RESULTS: Macroscopic examination revealed 21 tumors (7 located in the small bowel and 14 in the colon) in 19 rats.

On histological examination, we found 10 colonic adenocarcinomas (the first being observed at Week 22) and 7 adenocarcinoma in the small bowel.

In total, seven colon adenomas were found in five rats, six of which expressed high-grade dysplasia.

[(18)F]FDG uptake was lower in adenomas than in carcinomas.

[Title] Serrated pathway and APC (conventional)-type colorectal polyps: molecular-morphologic correlations, genetic pathways, and implications for classification.

This review addresses the genetic mutations and cell signaling pathway alterations in colorectal premalignant polyps, focusing on the link between molecular changes and morphologic features.

Biallelic APC (adenomatous polyposis coli) mutations are directly responsible for the specific and characteristic cytologic features of dysplastic cells in conventional tubular adenomas.

Sessile serrated adenomas (SSAs) are the precursor lesions of the serrated neoplasia pathway.

Intracellular butyrate inhibits histone deacetylase, allowing histone hyperacetylation and, eventually, transcriptional activation of specific genes.

Progressive loss of cell cycle control and decreased and altered cytoplasmic differentiation produce the characteristic constellation of morphologic changes of SSAs and traditional serrated adenomas.

[Title] An anti-adenoma antibody, Adnab-9, may reflect the risk for neoplastic progression in familial hamartomatous polyposis syndromes.

Patients with the hamartomatous polyposis Peutz-Jeghers and familial juvenile polyposis syndromes are predisposed to colorectal cancer but lack early genetic alterations found in adenomatous premalignant lesions.

We studied hamartomatous polyps for the expression of an early preneoplastic colorectal neoplasia risk marker also found in familial adenomatous polyposis patients.

Retrospective, genetic, and hospital archival tissue immunohistochemistry using Adnab-9, a premalignant marker often found in Paneth-like cells (PCs), was performed on sections of polyps from eight patients with Peutz-Jeghers syndrome, eight patients with familial juvenile polyposis, and 36 hyperplastic polyp control sections.

Hamartomatous polyposis patients also underwent specific genetic analysis.

Eighty-nine percent of Peutz-Jeghers syndrome polyps labeled with Adnab-9 compared with 63% for AD5; 88% of familial juvenile polyposis sections also labeled with Adnab-9.

Of the 36 hyperplastic polyp sections, only four (11%) labeled with Adnab-9 and one (3%) with AD5.

Adnab-9 labeling of PCs in the epithelial elements of hamartomatous colonic lesions of hereditary hamartomatous syndrome patients reflects the predisposition to colorectal cancer, further justifying early intervention strategies.

[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.

Hereditary CRC is conventionally divided into two major categories: hereditary non-polyposis colorectal cancer (HNPCC) and those related to polyposis syndromes including familial adenomatous polyposis (FAP), Peutz-Jegher syndrome (PJS), and juvenile polyposis (JP).

Germ-line mutation of the APC gene induces FAP, an autosomal dominant disorder, characterized by the development of hundreds to thousands of colonic adenomas.

Recently, a mutation on the MYH gene is increasingly being investigated in patients with multiple polyps, and autosomal recessive MYH polyposis is considered to be a new category of polyposis.

Although there is no polyposis, polyps seem to be more villous and dysplastic and appear to grow rapidly into CRCs.

PJS and JP are reported to be characterized by hamartomatous polyps throughout the GI tract and germ-line mutations in the STK11 gene (PJS) and the DPC4/BMPR1A gene (JP).

[Title] The loss of sarco/endoplasmic reticulum calcium transport ATPase 3 expression is an early event during the multistep process of colon carcinogenesis.

To better characterize the role of SERCA3 in colon carcinogenesis, its expression has been investigated in colonic epithelium, benign lesions, adenomas, and adenocarcinomas.

In addition, the regulation of SERCA3 expression was analyzed in the context of the adenomatous polyposis coli/beta-catenin/T-cell factor 4 (TCF4) pathway and of specificity protein 1 (Sp1)-like factor-dependent transcription.

We report that SERCA3 expression increased along the crypts as cells differentiated in normal colonic mucosa and in hyperplastic polyps, was moderately and heterogeneously expressed in colonic adenomas with expression levels inversely correlated with the degree of dysplasia, was barely detectable in well and moderately differentiated adenocarcinomas, and was absent in poorly differentiated tumors.

Inhibition of Sp1-like factor-dependent transcription blocked SERCA3 expression during cell differentiation, and SERCA3 expression was induced by the expression of dominant-negative TCF4 in colon cancer cells.

These data link SERCA3 expression to the state of differentiation of colonic epithelial cells, and relate SERCA3 expression, already decreased in adenomas, to enhanced adenomatous polyposis coli/beta-catenin/TCF4-dependent signaling and deficient Sp1-like factor-dependent transcription.

In conclusion, intracellular calcium homeostasis becomes progressively anomalous during colon carcinogenesis as reflected by deficient SERCA3 expression.

[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.

Using isoform-specific enzyme-linked immunosorbent assay and quantitative polymerase chain reaction, we found that over 90% of the VEGF in normal colonic tissue was VEGF(xxx)b, but there was a variable upregulation of VEGF(xxx) and downregulation of VEGF(xxx)b in paired human CRC samples.

Furthermore, cultured colonic adenoma cells expressed predominantly VEGF(xxx)b, whereas colonic carcinoma cells expressed predominantly VEGF(xxx).

However, adenoma cells exposed to hypoxia switched their expression from predominantly VEGF(xxx)b to predominantly VEGF(xxx).

VEGF(165)b overexpression in LS174t colon cancer cells inhibited colon carcinoma growth in mouse xenograft models.

However, although bevacizumab effectively inhibited the rapid growth of colon carcinomas expressing VEGF(165), it did not affect the slower growth of tumours from colonic carcinoma cells expressing VEGF(165)b.

Both bevacizumab and anti-VEGF(165)b-specific antibodies were cytotoxic to colonic epithelial cells, but less so to colonic carcinoma cells.

Together with the identification of an autocrine cytoprotective role for VEGF(165)b in colonic epithelial cells, these results indicate that bevacizumab treatment of human CRC may depend upon this balance of VEGF isoforms.

[Title] Ferric iron is genotoxic in non-transformed and preneoplastic human colon cells.

We previously demonstrated genotoxic effects by ferric iron using the human colon cancer cell line HT29.

Here we investigated ferric iron in primary non-transformed colon cells and in a preneoplastic colon adenoma cell line (LT97), which both are suitable models to study effects of carcinogens during early stages of cell transformation.

Comet FISH (fluorescence in situ hybridization) was used to assess specific effects on TP53.

Fe-NTA (0-1000 microM, 30 min, 37 degrees C) significantly induced single strand breaks in primary colon cells (500 microM Fe-NTA: Tail intensity [TI] 22.6%+/-5.0% versus RPMI control: TI 10.6%+/-3.9%, p<0.01) and in LT97 cells (1000 microM Fe-NTA: TI 26.8%+/-7.3% versus RPMI control: TI 11.1%+/-3.7%, p<0.01).

With the Comet FISH protocol lower concentrations of Fe-NTA significantly increased DNA damage already at 100 and 250 microM Fe-NTA in primary colon and LT97 adenoma cells, respectively.

In conclusion, Fe-NTA acts genotoxic in non-transformed and in preneoplastic human colon cells, in which it also enhances migration of TP53 at relatively low concentrations.

Translated to the in vivo situation these results suggest that iron overload putatively contributes to a genotoxic risk during early stages of colorectal carcinogenesis on account of its genotoxic potential in non-tumorigenic human colon cells.

[Title] The association between cigarette smoking and colorectal polyp recurrence (United States).

OBJECTIVE: Although evidence exists linking smoking to precancerous colorectal adenomatous polyps, few studies have examined the association between cigarette smoking and recurrence of colorectal polyps.

This association was investigated prospectively with data from the Polyp Prevention Trial.

The study was completed by 1872 men and women with presence of adenomas at baseline colonoscopy.

Multiple logistic regression analysis was used to examine the association between cigarette smoking and polyp recurrence (adenomatous and hyperplastic) up to four years from baseline.

RESULTS: Adenoma recurrence was not related to cigarette smoking.

Current smokers had increased odds of hyperplastic polyps at follow-up compared to never smokers (OR 2.88, 95% CI 2.06-4.01).

Current smoking was associated with subsequent distal (OR 3.44, 95% CI 2.38-4.95) and rectal (OR 3.53, 95% CI 2.15-5.78) hyperplastic polyps, but not subsequent proximal hyperplastic polyps.

Cigarette smoking was associated with subsequent multiple and small size (4 mm) hyperplastic polyps.

Significant linear trends were observed between development of subsequent hyperplastic polyps and all smoking variables.

CONCLUSIONS: Although no association with recurrent adenomas was observed, cigarette smoking was significantly associated with hyperplastic polyp development, except for those in the proximal colon.

This prospective study confirms that cigarette smoking has a significant effect on the development of hyperplastic colorectal polyps.

Colorectal cancer arises after a series of mutational events in the colon epithelia and is often used as a model of the multistep progression of tumorigenesis.

In order to examine the distinctive function that Ki-Ras plays in cancer development in the colon, we introduced constitutively active mutant Ki- and Ha-Ras genes into an intermediate-stage colon adenoma cell line (Caco-2).

We found that mutant active Ha-RasV12 was more efficient at transforming these colon epithelial cells as assessed by anchorage-independent growth, tumor formation in SCID mice and the development of mesenchymal morphology compared to transformation by Ki-RasV12.

Specifically, we found that Ki-RasV12 regulated genes involved in cytokine signaling, cell adhesion and colon development, whereas Ha-RasV12 mainly regulated genes involved in controlling cell morphology, correlating to an epithelial-mesenchymal transition only observed in these cells.

Our results demonstrate how 2 Ras isoforms regulate disparate biologic processes, revealing a number of genes whose deregulated expression may influence colon carcinogenesis (supplementary material for this article can be found on the International Journal of Cancer website at http://www.interscience.wiley.com/jpages/0020-7136/suppmat/index.html).

[Title] Prevalence of adenomas and carcinomas in the ileal pouch after proctocolectomy in patients with familial adenomatous polyposis.

PURPOSE: Restorative proctocolectomy has become the most common surgical option for patients with familial adenomatous polyposis (FAP).

However, adenomas may develop in the ileal pouch mucosa over time, and even carcinoma in the pouch has been reported.

Our aim was to evaluate the prevalence, nature, and etiology of ileal pouch and nonpouch adenomas and carcinoma in patients with FAP.

All patients were followed with a standardized protocol including chromoendoscopy and biopsies of visible polyps in the ileal pouch and nonpouch mucosa.

RESULTS: Sixteen of 24 pouch patients (Kock and IPAA) developed adenomas in the ileal pouch mucosa, and all patients with IRA developed adenomas in the rectal mucosa.

The prevalence of ileal adenomas was significantly higher in pouch patients than in IRA patients (P = 0.002).

Only one patient with Kock showed adenoma in the prepouch area.

Two cases of adenocarcinomas and one case of advanced adenoma were found in the ileal pouch mucosa.

CONCLUSION: Our results show a high frequency of adenomas in the ileal pouch mucosa, with evolution into carcinoma in some patients.
