Summary of "Lower Gastrointestinal Conditions: Colorectal Cancer Screening and Prevention."

Colorectal cancer (CRC) is the third most commonly diagnosed malignancy and the second most common cause of cancer mortality worldwide. It was estimated that approximately 50,630 mortalities due to CRC would occur in the United States in 2018. Seventy percent of CRC originates from adenomatous polyps that become dysplastic over time. Risk factors for CRC include genetic syndromes, such as familial polyposis syndromes and Lynch syndrome; inflammatory bowel disease; dietary and lifestyle factors; and family history of advanced adenomas. The U.S. Preventive Services Task Force and the U.S. Multi-Society Task Force on CRC recommend screening beginning at age 50 years for patients at average risk. Multiple screening tools may be offered based on availability and patient comorbid conditions, personal preferences, and risk factors. In the United States, colonoscopy continues to be the screening modality of choice but is not without risks and adverse effects. Currently, genetic testing has no role in the screening of patients at average risk. Research into CRC prevention is ongoing but there currently are no recommended strategies other than adequate screening.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.

Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).

Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.

A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.

Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.
