Incidence of rectosigmoid adenomatous polyps in subjects without prior colorectal adenoma or cancer: a prospective cohort study. (1/224)

BACKGROUND: Subjects without known colorectal adenomas or cancer constitute a large majority of the population where 85% of all cases of colorectal cancer are thought to occur. Consequently these people should be considered for screening to decrease mortality from colorectal cancer in the general population. AIMS: To estimate the incidence rate of rectosigmoid adenomas in these subjects. METHODS: Subjects without adenomas or cancer at a previous examination which had visualised the rectosigmoid underwent a fibre endoscopy every three years. Endoscopic data and population characteristics were collected prospectively. RESULTS: A total of 450 subjects fulfilled the selection criteria; 287 (64%) underwent at least two examinations, and 163 had three or more. At the second examination, with a mean delay of 39 months, the incidence rate of rectosigmoid adenomas was 1.50% per patient year. The rate was 1.75% per patient year (95% CI 0.80-3.33) at the third endoscopy with an additional mean delay of 38 months. The cumulative incidence rate at six years was 7.3% (95% CI 4.3-10.3), representing a mean of 1.2% per patient year. This rate increased with age and was higher for men than for women after age adjustment (p< 0.03). CONCLUSIONS: The incidence rates are very low compared with those of patients with prior adenomas. These results should be considered in establishing rectosigmoid adenoma screening strategies.  (+info)

Dietary determinants of colorectal proliferation in the normal mucosa of subjects with previous colon adenomas. (2/224)

Dietary determinants of colorectal mucosa proliferation were studied in 69 subjects previously operated for at least two sporadic colon adenomas. Information on recent dietary habits was collected by a validated food frequency questionnaire, and proliferation was measured by [3H]thymidine incorporation in colorectal biopsies by determining the labeling index (LI) and the percentage of LI in the upper part of the crypt, two parameters that are increased in subjects at high risk of colon cancer. The LI was significantly higher in women as compared with men (P = 0.01). Diet showed several associations with colorectal mucosa proliferation: (a) subjects in the highest tertile of fish consumption had a significantly lower LI (P = 0.0013) compared with those in the lower tertiles [5.20 +/- 1.87 versus 6.80 +/- 2.18 (mean +/- SD)]; (b) subjects with a low red meat consumption had lower proliferation in the upper part of the crypt [2.38 +/- 2.10, 5.30 +/- 4.62, and 5.89 +/- 4.82 in the low, middle, and high tertile of consumption, respectively (mean +/- SD); P = 0.0093]; (c) according to estimated nutrient intakes, the LI was lower in subjects reporting a high intake of starch (P = 0.006) and higher in subjects with a low intake of beta-carotene (P = 0.002). The results show that subjects reporting a diet rich in fish, starch, and beta-carotene and low in red meat had lower colorectal mucosa proliferation and a normal pattern of proliferation along the crypt. Given the correlation between colorectal proliferative activity and colon cancer risk, such a dietary pattern might be beneficial for subjects at high risk of colon cancer.  (+info)

Flat adenomas exist in asymptomatic people: important implications for colorectal cancer screening programmes. (3/224)

BACKGROUND: Flat adenomas are non-exophytic with a flat top or central depression and histologically the depth of dysplastic tissue is never more than twice the mucosal thickness. Flat adenomas frequently contain severely dysplastic tissue, and may progress rapidly through the adenoma-carcinoma sequence. Flat lesions have never been described in a British asymptomatic population. AIMS: To determine whether flat adenomas exist in an asymptomatic population participating in a large randomised controlled trial of flexible sigmoidoscopy screening. PATIENTS: A total of 3000 subjects (aged 55-64 years) underwent screening by flexible sigmoidoscopy. METHODS: All polyps were removed and sent for histology. The number of polyps with endoscopic and histological features of flat adenomas was recorded. RESULTS: Three subjects had a total of four flat lesions--that is, one per 1000 people screened. Three contained severely dysplastic tissue, one a focus of adenocarcinoma. Three of the four lesions were less than 5 mm in size and the fourth was 15 mm in diameter. CONCLUSIONS: Flat lesions with severe dysplasia exist in the asymptomatic population. This has major implications for gastroenterologists who should be trained to identify them. Their existence is of importance to molecular biologists and epidemiologists investigating the aetiology of colorectal cancer.  (+info)

Effect of aspirin on prostaglandin E2 formation and transforming growth factor alpha expression in human rectal mucosa from individuals with a history of adenomatous polyps of the colon. (4/224)

Colorectal cancer is the second-most frequent cause of cancer mortality in the United States. Human epidemiology and laboratory studies indicate that aspirin may be an effective colorectal cancer chemopreventive agent. This study was designed to determine whether treatment with 81 mg of aspirin per day for 3 months would alter two putative surrogate end point biomarkers of chemoprevention of colorectal cancer [i.e., mucosal prostaglandin E2 (PGE2) formation and transforming growth factor alpha (TGF-alpha) expression] in normal-appearing rectal mucosa from individuals with a history of adenomatous polyps. Rectal biopsies were obtained by flexible sigmoidoscopy at three sequential time points: (a) after a 1-month placebo run-in period (baseline), (b) after 3 months of ingesting 81 mg of aspirin (as a single tablet) once per day, and (c) after 3 months of ingesting a placebo tablet once per day (washout period). Daily aspirin significantly suppressed PGE2 formation, but this significant suppression was completely reversed when aspirin was withdrawn. The extent of TGF-alpha staining in rectal crypts was also reduced significantly (P = 0.039) by daily aspirin. After a 3-month placebo-washout period, however, the mean extent of TGF-alpha staining was not significantly different from either baseline or the aspirin time point. Thus, 81 mg of aspirin daily significantly reduced rectal mucosal PGE2 formation and TGF-alpha expression in patients with a history of adenomatous polyps. These putative surrogate end point biomarkers may be useful intermediate end points in future colorectal cancer chemoprevention trials.  (+info)

Evaluation of 5-aminosalicylic acid (5-ASA) for cancer chemoprevention: lack of efficacy against nascent adenomatous polyps in the Apc(Min) mouse. (5/224)

Recent experimental and epidemiological evidence suggests that nonsteroidal anti-inflammatory drugs (NSAIDs) are effective in the prevention of colorectal cancer. However, the toxicity associated with the long-term use of most classical NSAIDs has limited their usefulness for the purpose of cancer chemoprevention. Inflammatory bowel disease (IBD) patients, in particular, are sensitive to the adverse side effects of NSAIDs, and these patients also have an increased risk for the development of intestinal cancer. 5-Aminosalicylic acid (5-ASA) is an anti-inflammatory drug commonly used in the treatment of IBD and may provide protection against the development of colorectal cancer in these patients. To directly evaluate the ability of 5-ASA to suppress intestinal tumors, we studied several formulations of 5-ASA (free acid, sulfasalazine, and Pentasa) at multiple oral dosage levels [500, 2400, 4800, and 9600 parts/million (ppm)] in the adenomatous polyposis coli (Apc) mouse model of multiple intestinal neoplasia (Min). Although the ApcMin mouse is not a model of colitis-associated neoplasia, it is, nonetheless, a useful model for assessing the ability of anti-inflammatory agents to prevent tumor formation in a genetically preinitiated population of cells. We used a study design in which drug was provided ad libitum through the diet beginning at the time of weaning (28 days of age) until 100 days of age. We included 200 ppm of piroxicam and 160 ppm of sulindac as positive controls, and the negative control was AIN-93G diet alone. Treatment with either piroxicam or sulindac produced statistically significant reductions in intestinal tumor multiplicity (95% and 83% reductions in tumor number, respectively; P < 0.001 versus controls). By contrast, none of the 5-ASA drug formulations or dosage levels produced consistent dose-progressive changes in polyp number, distribution, or size, despite high luminal and serum concentrations of 5-ASA and its primary metabolite N-acetyl-5-ASA. Thus, 5-ASA does not seem to possess direct chemosuppressive activity against the development of nascent intestinal adenomas in the ApcMin mouse. However, because intestinal tumor development in the ApcMin mouse is driven by a germline mutation in the Apc gene rather than by chronic inflammation, we caution that these findings do not definitively exclude the possibility that 5-ASA may exert a chemopreventive effect in human IBD patients.  (+info)

A case-control study of colorectal adenomatous polyps and consumption of foods containing partially hydrogenated oils. (6/224)

The trans fatty acids produced by partially hydrogenating vegetable oils may cause colorectal neoplasia by interfering with cell membrane function or eicosanoid synthesis. This possibility provides a rationale for looking at the relation between colorectal adenomatous polyps and consumption of foods containing partially hydrogenated vegetable oils (PHVOs). A total of 516 cases and 551 controls who underwent screening sigmoidoscopy from 1991-1993 were recruited from a prepaid Los Angeles health plan. Subjects were interviewed and given a self-administered food frequency questionnaire. Food items containing PHVOs were divided into four groups characterized by principal ingredients and preparation methods: sweetened baked goods, candy bars, oils and condiments, and french fries and chips. After adjusting for age, sex, physical activity, body mass index, smoking, total energy, and red meat and vegetable intake, there was a positive association between polyps and sweetened baked goods [350+ versus <50 kcal/day (odds ratio, 2.1; 95% confidence interval, 1.3-3.5)]. No association was found with the other food groups after adjustment for dietary and nondietary covariates. Neither was total dietary trans fatty acid associated with adenomas after adjustment for sweetened baked goods and other covariates. These results do not support the hypothesis that eating foods containing PHVOs increases the risk of colorectal adenomas, but they are consistent with the hypothesis that foods high in fat and sugar and low in fiber and correlated micronutrients increase the risk of adenomas.  (+info)

Reliability and validity of a self-administered food frequency questionnaire in a chemoprevention trial of adenoma recurrence. (7/224)

Various chemoprevention trials have assessed dietary intake by means of food frequency questionnaires. However, it is important to assess the degree to which such questionnaires can measure diet. We conducted reproducibility and validity analyses of our Arizona Food Frequency Questionnaire (AFFQ) in our recently completed, randomized, Phase III chemoprevention trial testing the effects of a wheat bran fiber supplement on colorectal adenoma recurrence. A total of 139 individuals provided a baseline and year 1 AFFQ and a set of 4-day dietary records collected over a period of 1 month. The reproducibility analyses of the AFFQ administered 1 year apart showed a mean intraclass correlation of 0.54 for unadjusted nutrients and 0.48 for energy-adjusted nutrients. The relative validity of the AFFQ, as compared with the average of the 4-day diet records, showed a mean deattenuated correlation of 0.49 (range, 0.22-0.65) for the baseline AFFQ and 0.49 (range, 0.25-0.67) for the year 1 AFFQ. When data from both AFFQs were combined and compared with the diet records, there was a slight improvement in the overall deattenuated correlations (mean, 0.56; range, 0.33-0.71). The correlations we observed for macro- and micronutrient intake were within the overall range of those reported in the literature. Reliability and validity studies of dietary instruments are feasible in the setting of a chemoprevention trial and should be conducted when the instrument's performance has not been previously assessed in the target population.  (+info)

Patterns of proliferative changes in crypts bordering colonic tumors: zonal histology and cell cycle marker expression. (8/224)

Proliferative crypt changes have been noted in mucosa bordering colonic carcinomas, but their biological significance is disputed. We anticipated that zonal patterning of histological changes and cell cycle marker expression would provide clues to the pathogenesis of these border changes. 81 specimens were examined including carcinomas, adenomatours polyps, adenomas with early carcinoma, flat adenomas and aberrant crypt foci. The spatial distribution and frequency of micro-architectural features, and mucosal thickness were determined in a border domain of 150 300 sequential crypts/specimen. Immunocytochemical expression of Ki67 and p53 antigens in crypts also was semi-quantitatively examined. We found that in 100% of carcinomas two histologically abnormal zones (Proximate and Middle) separated tumor from normal mucosa. Differences in the feature frequency between zones were statistically significant (p<0.05). Both zones showed mild increases in crypt cell expression of Ki67, with a statistically significant relationship to zonal patterning (p<0.005). Weak expression of p53 only appeared in rare cells. Crypt elongation with mucosal thickening (1.9x normal, p<0.001) in the Proximate and Middle zones distinguished carcinomas from border changes in all benign lesions, except flat adenomas. Since this change occurs in all cases of carcinoma, there is no correlation with tumor stage or grade. Also in carcinomas, elaborate complexes of attached crypts (connected crypt structures) were characteristic of the Middle zone, so that proximate zone was always architecturally simpler. We conclude, that despite continuous carcinoma growth, the invaded border mucosa maintains a prototypical zonal organization of molecular and histological crypt changes This spatially organized reaction pattern is likely to reflect an interplay between regulated growth and destructive processes in response to advancing carcinoma. Compared to the edges of benign colonic tumors, the edges of carcinomas are distinctive and consistent enough to be diagnostically useful.  (+info)

Colorectal tumors mostly arise from sporadic adenomatous polyps. Polyps are defined as a mass of cells that protrudes into the lumen of the colon. Adenomatous polyps are benign neoplasms that, by definition display some characteristics of dysplasia. It has been shown that polyps were benign tumors which may undergo malignant transformation. Adenomatous polyps have been classified into three histologic types; tubular, tubulovillous, and villous with increasing malignant potential. The ability to differentially diagnose these colorectal adenomatous polyps is important for therapeutic intervention. To date, little efforts have been directed to identifying genetic changes involved in adenomatous polyps. This study was designed to examine the relevance of mitochondrial genome alterations in the three adenomatous polyps. Using high resolution restriction endonucleases and PCR-based sequencing, fifty-seven primary fresh frozen tissues of adenomatous polyps (37 tumors and 20 matched surrounding normal tissues)

High prevalence of adenomatous colorectal polyps in young cancer survivors treated with abdominal radiation therapy: results of a prospective trial ...
The diagnostic difficulties of differentiating epithelial misplacement from invasive cancer in colorectal adenomatous polyps have been recognised for many years. Nevertheless, the introduction of population screening in the UK has resulted in extraordinary diagnostic problems. Larger sigmoid colonic adenomatous polyps, which are those most likely to show epithelial misplacement, are specifically selected into such screening programmes, because these polyps are likely to bleed and screening is based on the detection of occult blood. The diagnostic challenges associated with this particular phenomenon have necessitated the institution of an Expert Board: this is a review of the first five years of its practice, during which time 256 polyps from 249 patients have been assessed. Indeed, the Expert Board contains three pathologists, because those pathologists do not necessarily agree, and a consensus diagnosis is required to drive appropriate patient management. However, this study has shown ...
Results:. The risk for colorectal cancer was elevated (RR, 1.74 [95% CI, 1.24 to 2.45]) among first-degree relatives of patients with newly diagnosed adenomas compared with the risk among first-degree relatives of controls. This increased risk was the same for parents (RR, 1.58 [CI, 1.07 to 2.34]) and siblings (RR, 1.58 [CI, 0.81 to 3.08]). First-degree relatives of patients with adenomas did not have elevated risk for other cancers. The risk for colorectal cancer among family members increased with decreasing age at diagnosis of adenoma in probands. Among first-degree relatives of patients who were 50 years of age or younger when the adenoma was diagnosed, the risk was more than four times greater (RR, 4.36 [CI, 2.24 to 8.51]) than that among first-degree relatives of patients who were older than 60 years of age when the adenoma was diagnosed. ...

TY - JOUR. T1 - In vitro models of human colonic adenomatous polyps.. AU - Willson, J. K.. AU - Bittner, G. N.. PY - 1988. Y1 - 1988. N2 - In this report we describe methods which were used to cultivate cell lines from adenomatous polyps. Many of the techniques used have evolved from our past experience with the cultivation of colonic epithelial neoplastic cells (McBain et al., 1984) and the experience of others successful in the cultivation of benign and cancerous colon tissues. We feel that the preservation of cell-to-cell associations is a key to our successful cultivation of adenomas. Moyer (Moyer and Aust, 1984) has also pointed out the importance of preserving cell-to-cell associations in her successful studies to culture normal and neoplastic colonic tissues. Friedmans primary culture system for adenomatous polyps (Friedman et al., 1981) is further evidence supporting this point. Using the techniques described in this report, three cell lines, two small tubular polyps and one villous ...
Adapted from http://www.genetests.org/ It is now recognized that FAP has a broad spectrum of clinical manifestations and, in addition to classic FAP, includes three phenotypes that previously were thought to be discrete clinical entities distinct from FAP: attenuated FAP, Gardner syndrome, and Turcot syndrome. Patients with classic FAP present with over 100 colorectal adenomatous polyps or less then 100 adenomatous polyps AND a relative diagnosed with FAP. Patients with attenuated FAP (AFAP) present with colonic adenomatous polyps less than 100 in number and more proximally found in the colon than in classic FAP. In patients with a fewer number of polyps (average of 30), a family history of colon cancer in persons less than age 60 years with multiple adenomatous polyps is necessary for diagnosis. The average age of colon cancer diagnosis in individuals with attenuated FAP is age 50 to 55 years, which is 10-15 years later than that observed in classic FAP. A predominance of right-sided colorectal ...
It is generally accepted that adenomatous polyps represent the natural precursor of many colorectal malignancies. The sequence, however, which leads from a normally appearing mucosa to cancer is complex and involves many steps, including a hyperproliferative mucosa with an upward expansion of the replicative compartment. The current study evaluates cell replication in normal colorectal mucosa of patients with adenomatous polyps of various types and relates the observed findings to the main clinical and morphologic features of adenomas. Forty-four patients with polyps and 27 controls entered the study. Samples of colorectal mucosa were taken at endoscopy and cell replication was evaluated with a standard autoradiographic procedure. Cell replication was expressed as labeling index (LI), in the whole crypt and in each of the five longitudinal compartments in which the crypts were divided. Total LI and LI per crypt compartment were significantly higher (P , 0.02 and P , 0.01, respectively) than in ...

Most colorectal cancers evolve from colorectal adenomatous polyps in a pathway known as the adenoma to carcinoma sequence. Early detection and removal of colorectal adenomas can prevent the development of colorectal cancer. The vast majority of these polyps can be resected endoscopically. Advances in endoscopic resection techniques have led to expanded indications for endoscopic polypectomy, whereby giant polyps, scarred lesions and early cancers may be cured. We will outline conventional endoscopic mucosal resection techniques as well as more complex resection methods such as endoscopic submucosal dissection, full thickness resection and the use of combined endoscopic and laparoscopic assisted approaches to resection. We will also explore the role of a virtual multidisciplinary team to aid decision-making when managing large and complex colorectal polyps. This review will provide an update on the endoscopic management of colorectal polyps and highlight exciting new developments in this ...

Epidemiological and animal studies suggest a role for calcium in the chemoprevention of colorectal neoplasia. This study was designed to investigate whether supplemental oral calcium has a suppressant effect on colonic mucosal ornithine decarboxylase (ODC) and tyrosine kinase activities in patients with adenomatous polyps or a history of adenomatous polyps and whether this is affected by age. ODC and tyrosine kinase activities were measured in rectal mucosal biopsies of 19 male patients (age, years 46-85 years; mean, 66 years) with adenomatous polyps or a history of adenomatous polyps before and after 1 week of calcium supplementation p.o.

The basal rectal mucosal ODC activity of patients ≥64 years old was nearly 4-fold higher than that of patients ,64 years old (P , 0.005).

Screening for colorectal cancer with fecal occult blood testing and lower endoscopy with removal of polyps reduce the mortality rate from colorectal cancer. Screening with flexible sigmoidoscopy is becoming standard for asymptomatic persons older than 50 years. Because adenomatous polyps found in the distal colon have been associated with adenomatous polyps in the proximal colon, full colonoscopy is generally recommended for patients with distal adenomas. Small polyps (less than 1 cm) seem to have a lower risk of malignant transformation than do larger polyps and are less likely to be malignant or to have high-grade histologic features. With increasing data, it appears that there is a low prevalence of histologically advanced polyps in the proximal colon among patients with small distal tubular adenomas. Wallace and associates conducted a study to determine the prevalence of advanced adenomatous polyps in the proximal colon among patients with small tubular adenomas found on flexible ...

The mononuclear leukocytes from peripheral blood samples of individuals with (n = 30) and without (n = 48) colonic polyps were examined for their abilities to carry out unscheduled DNA synthesis (UDS) induced by N-acetoxy-N-2-fluorenylacetamide (N-AcO-2-FAA). Individuals with polyps had significantly reduced UDS values compared to the nonpolyp group (P , 0.01). Furthermore, in a more comprehensive study, patients with hyperplastic polyps had N-AcO-2-FAA-induced UDS values not significantly different from control individuals who were asymptomatic and free from colonic disease as judged by complete colonoscopy. However, patients who had had adenomatous polyps in their large bowel had significantly reduced levels of N-AcO-2-FAA-induced UDS in their mononuclear leukocytes (P , 0.005). When N-AcO-2-FAA binding to DNA determinations were made in parallel and DNA repair proficiency indices were calculated (i.e., N-AcO-2-FAA-induced UDS/N-AcO-2-FAA binding to DNA), the patients with adenomatous polyps ...
Caroline Fournier MSc, Research Associate, Division of Clinical Epidemiology, The Research Institute of the McGill University Health Centre, Montreal, QC.. Colorectal cancer (CRC) is a commonly diagnosed cancer and a leading cause of cancer deaths in Canada and the industrialized world. According to cancer registries, incidence varies by age, geographical location, site, and time. CRC screening reduces both CRC incidence through removal of premalignant polyps and CRC deaths through early detection and treatment. Health Canada considers CRC an ideal target for mass screening of individuals 50 years of age and older. This article reviews the epidemiology of CRC and the reasoning behind the development of screening guidelines for persons 50 years of age and older. Various Canadian and U.S. guidelines are detailed. Routine screening of average-risk individuals is advocated. Finally, the review highlights trends in patient utilization of CRC screening as well as the role of screening in an aging ...
Epidemiologic studies of colorectal neoplasia have usually examined body mass index as a risk factor, but not other aspects of obesity.

Above is an adenomatous polyp. (You may recognize this polyp from last weeks post.) In order to prevent this patient from developing colon cancer in the next few years, it needs to be removed. The safest and most effective way of removing a polyp like this is by injecting fluid underneath the polyp to lift it off the deeper layers of the colon wall. Then a device called a snare is used to capture the polyp and current is applied as the snare is closed-cutting the polyp off.. For this polyp, the blue stuff I used is a substance called Eleview. Its a great alternative to the typical saline that is normally used for this purpose, as it forms a longer-lasting cushion and contains blue dye which makes it technically easier and safer to get a complete resection the first time around.. ...
Although many people avoid the test out of fear or nervousness, a new study provides what independent researchers call the best evidence yet that colonoscopy - perhaps the most unloved cancer screening test - prevents deaths. In patients tracked for as long as 20 years, the death rate from colorectal cancer was cut by 53 percent in those who had the test and whose doctors removed precancerous growths, known as adenomatous polyps, researchers reported last month in The New England Journal of Medicine. The test examines the inside of the intestine with a camera-tipped tube. Earlier research had proved that removing precancerous polyps could greatly reduce the incidence of colorectal cancer. But a major question remained: Did removing the polyps really save lives? This study, according to experts, puts that debate to rest.. Screening Information ...
What is FAP?. FAP is an inherited condition, where polyps develop in the intestinal tract, but primarily it affects the large intestine (colon and rectum). It is due to a genetic mutation that interferes with the normal function of APC, an important gene that controls how fast cells grow. The gene mutation is most often inherited from a parent, but 30% of FAP patients develop the mutation during conception and do not have a parent with FAP. If you have inherited the gene mutation, numerous adenomatous polyps, which are precancerous growths, will develop in the lining of the colon and rectum. If undetected and untreated, one or more of the polyps will eventually become cancerous. Fortunately, with early diagnosis and treatment, FAP patients can avoid cancer and lead normal, healthy lives.. How is FAP inherited?. Each child of a parent with FAP has a 50% chance of inheriting the gene. If you have inherited the gene for FAP, you will eventually develop polyps and may< pass along the condition to ...

As an alumna of Cornell who had been thrilled by the selection of the universitys first female president, Elizabeth Garrett, last fall, I was deeply pained to learn of her untimely death from colon cancer at age 52 last month. May it be a teachable moment that could save many from a disease that will be diagnosed in an estimated 134,000 people and claim 49,000 lives in the United States this year.. Although colorectal cancer is the third most common cancer, it is the second leading cause of cancer deaths, after lung cancer. Detection guidelines call for screening to begin at 50 for most people, but colon cancer is now increasing in people under 50, and everyone should be aware of the risks and early warning signs.. While the circumstances that led to Garretts diagnosis have not been publicly revealed, colon cancer can nearly always be prevented through detection and removal of its precursor lesions, commonly called adenomas or adenomatous polyps. It can most often be cured if one of several ...
HNPCC is caused by autosomal dominant inheritance of mutations of any one of the four mismatch repair genes, MLH1, MSH2, MSH6 and PMS2 [8]. It may account for up to 5% of colon cancer cases. HNPCC is clinically defined by the Amsterdam I criteria (Am), which are: 1) three relatives with colorectal cancer, two of them being first-degree relative of the third; 2) at least two affected generations; and, 3) at least one case having a diagnosis at an age ,50 years. The average age of colon cancer diagnosis is 45 years, but may be older, and frequent syndronous and metachronous cancers are found. Adenomatous polyps precede the cancer, but only one or several are usually found. Other cancers that occur as part of the syndrome include uterine (40%), and 5% to 10% ovarian, gastric, biliary, renal, CNS, ureter and renal pelvis, and duodenum and small bowel. Amsterdam II criteria are similar to those listed above, but include colon or any of these other cancers. Am II criteria are more sensitive but less ...

An adenoma is a polyp made up of tissue that looks much like the normal lining of your colon, although it is different in several important ways when it is looked at under the microscope. The growth pattern is only important because it helps determine when you will need your next colonoscopy to make sure you dont develop colon cancer in the future. Cell overgrowth resulting from mutations in the APC gene leads to the adenomatous polyps of the colon colon polyps seen in familial adenomatous polyposis. There are 2 major growth patterns: tubular and villous. In addition to this, a stroboscope (flashing light) may be used to observe the movement of the vocal folds during speech. Adenomas with a villous growth pattern are also more likely to have cancers develop in them. Erratum in: Gastroenterology. Some people have a variant of the disorder, called attenuated familial adenomatous polyposis, in which polyp growth is delayed. Larger adenomas more often have cancers developing in them. The average ...

Secreted frizzled-related protein 2, (SFRP2) is a Wnt inhibitor whose promoter CpGs were recently found to be methylated at high frequency in colorectal cancers (CRCs). We hypothesized that the pattern of SFRP2 methylation may differ throughout the promoter during progressive tumorigenesis. Using combined bisulfite restriction analysis (COBRA), two methylation-sensitive regions (Regions A and B) of the SFRP2 promoter were investigated in 569 specimens of colorectal tissue:222 CRCs, 103 adenomatous polyps (APs), 208 normal colonic mucosa from CRC patients (N-Cs), and 36 normal colonic mucosa from subjects with no evidence of colorectal neoplasia at colonoscopy (N-Ns). Extensive (including both Regions A and B) and partial (either Region A or B) SFRP2 methylation levels were found in 61.7% and 24.8% of CRCs, 8.7% and 37.9% of APs, 3.9% and 39.9% of N-Cs, and 0% and 30.6% of N-Ns, respectively. Extensive methylation of the SFRP2 promoter was present primarily in CRCs, while partial methylation was ...

New research finds that exercising daily in adolescence and adulthood reduces the risk of developing adenomatous polyps at an older age.
The trial, known as APPROVe (Adenomatous Polyp Prevention on Vioxx), was the longest test yet of Vioxx as a chemoprevention agent, and was designed to determine whether the drug could prevent the re-growth of precancerous colon polyps in people who had already had polyps removed. The prospective chemoprevention study randomized 2,586 participants from 108 centers in 29 countries to receive either 25 mgs. of Vioxx daily or a placebo drug for three years, 2001-2004. The trial was stopped September 30, 2004 - approximately two months before its planned completion. ...

In most cases signs of Colon Cancer begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Over time some of these polyps become colon cancers.. Polyps may be small and produce few, if any, symptoms. For this reason, doctors recommend regular screening tests to help prevent Colon Cancer by identifying and removing polyps before they become Colon Cancer.. If the cancer spreads, or metastasizes, additional symptoms can present themselves in the newly affected area. Symptoms of metastasis ultimately depend on the location to which the cancer has spread, and the liver is the most common place of metastasis.. In order to diagnose Colon Cancer, physicians will request a complete physical exam as well as personal and family medical histories. Diagnoses are usually made after the physician conducts a colonoscopy or a barium enema x-ray.. It is also highly treatable if found in its early stages. Screening is encouraged at age 50, and before age 50 if there is a strong family ...
Despite the recognition that colon cancer is largely preventable, it remains the second leading cause of cancer-related deaths in the United States. Historically, screening approaches have sought to detect established cancer, but the identification of precancerous adenomatous polyps is clearly the preferable goal. Not all adenomas progress to cancer, but those that are larger than 1 cm or contain villous histology or high-grade dysplasia are most likely to do so. The current multisociety guidelines now emphasize detection of precancerous polyps as the most effective strategy to prevent deaths from colon cancer, and structural examinations, such as colonoscopy, are recommended for this purpose (1). Testing for occult blood in stool is notoriously insensitive for detecting adenomas (2) ...

Screening, surveillance and diagnostic indications for colonoscopy are based on guidelines from a variety of specialty societies and government organizations. The source for each of the indications listed above is indicated by the referenced citation. Generally speaking, screening refers to an effort or program which is used to detect a condition in an asymptomatic individual so that early detection and treatment can be provided for those who test positive for the condition. Surveillance refers to the systematic identification and evaluation of individuals considered to be at increased-risk for the occurrence or recurrence of a condition or disease (for example; colorectal cancer or adenomatous polyps. Diagnostic testing is typically done to confirm or rule out a condition in an individual who is symptomatic or who, for some other reason, is believed to have a specific condition. Several organizations have published recommendations for colorectal cancer screening and provided guidance on when ...

Conversion to laparotomy became necessary in 3% of cases. The perioperative morbidity rate was 21%, and malignant transformation occurred in a total of 18% of the adenomatous polyps. The team found the median number of lymph nodes removed was 12, and lymph node metastases were seen in a total of 15% of the patients. The researchers observed that the estimated 5-year overall and disease-free survival rates were 92% and 81%, respectively.. Dr Benedix s team concluded, For the management of endoscopically unresectable polyps, laparoscopic resection is currently the technique of choice. In addition to the benefits of minimally invasive surgery, in the hands of an experienced surgeon it achieves results comparable with those of open surgery. In view of the high rate of malignant transformation and the absence of unequivocal factors predictive of already present malignant transformation, an oncologically radical operation is essential. In the elderly patient presenting with comorbidities limited ...
