  • DESCRIPTION
  • Small Cell Cancer of the Large Intestine is an aggressive (fast-growing) cancer that forms in tissues of the intestine and can spread to other parts of the body. The cancer cells look small and oval-shaped when looked at under a microscope. Small cell carcinoma of the large intestine represents .2% to .8% of all colorectal malignancies. General symptoms may include: change in bowel habits, abdominal pain and weight loss.
  • ALTERNATE NAMES
  • Cancer of the Colon, Colorectal Small Cell Cancer, Small Cell Carcinoma of the Large Intestine
  • DIAGNOSTIC TESTING AND CODING
  • The diagnosis of colorectal small cell carcinoma is confirmed by pathology and the use of immunohistochemistry. Specific staining for CD56, pancytokeratin, LMWK, CK 7 and 19 are usually positive in small cell malignancies. Early diagnosis depends on routine screening. Occult blood study, sigmoidoscopy, colonoscopy, CT scan, endoscopy are used.
  • TREATMENT
  • Treatment for colorectal small cell carcinoma is the use of combined chemotherapy and radiotherapy as is used in small cell carcinoma of the lung.
  • PROGRESSION
  • Survival rates are poor, usually less than 2 years.
  • SUGGESTED PROGRAMMATIC ASSESSMENT*
