Deficient Pms2, ERCC1, Ku86, CcOI in Field Defects During Progression to Colon Cancer
Published on: July 28, 2010
Summary
Malignant colon polyps show a significant left-sided distribution, with 95% found distal to the splenic flexure. This contrasts with the general polyp distribution, highlighting the importance of colon polyp removal.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Oncology
Background:
- Colorectal polyps are common, and early detection and removal are crucial for preventing colorectal cancer.
- Understanding the distribution of polyps, particularly malignant ones, can inform screening and treatment strategies.
Purpose of the Study:
- To determine if the distribution of malignant colon polyps differs from the distribution of all colon polyps.
- To analyze the location of endoscopically removed polyps within the colon.
Main Methods:
- Analysis of a consecutive series of 1226 endoscopically removed polyps.
- Comparison of the distribution of malignant polyps versus all polyps.
Main Results:
- Malignant polyps demonstrate a strong preponderance in the left colon.
- 95% of malignant polyps were located distal to the splenic flexure.
- This segment accounted for only 72% of all polyps.
Conclusions:
- Malignant colon polyps are disproportionately located in the left colon compared to all polyps.
- The findings underscore the critical importance of thorough polyp removal during colonoscopy.
- Further research is needed to elucidate the reasons behind this observed distribution.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:26Inflammatory Bowel Disease I: Introduction
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
