Rectal Cancer

  • Theodore J. Saclarides

Approximately 50,000 new rectal cancers are diagnosed annually in the United States. The most common histologic form is adenocarcinoma; other variants include squamous cell carcinoma (for the distal rectum), neuroendocrine cancers, sarcomas, and lymphoma. This discussion focuses on adenocarcinoma. Most tumors are found on digital rectal exams or colonoscopy performed for screening purposes, or surveillance of high-risk groups (genetic predisposition, inflammatory bowel disease, family history, prior personal history of colorectal polyps, or cancer).
