Competing-Risk Nomogram for Predicting Cancer-Specific Survival in Multiple Primary Colorectal Cancer Patients after Surgery
Published on: September 27, 2024
Abstract:
Man and laboratory rodents exposed to chemical carcinogens both show changes in growth characteristics of colonic epithelial cells during neoplastic transformation. Progressive phases of abnormal cell development appear in colonic epithelial cells which gain an increased ability to proliferate and accumulate in the mucosa. These phases in the expression of neoplastic transformation of colonic cells are best defined in the dominant inherited disease of man as adenomatosis of the colon and rectum. Individuals with inherited adenomatosis and those in lesser risk categories can be classified by cell phenotype based on changes in the proliferation and maturation of colonic and other cells. These classifications are leading to new predictive indices which identify heightened degrees of susceptibility of individuals who are at increased risk for colon cancer, and the stage of development of their disease. The indices also are being used to study the contribution of specific elements in the enviroment that modify or accelerate the progression of disease.

Tumor Progression
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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
