General symptoms may include: change in bowel habits, abdominal pain and weight loss.

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

PROGRESSION

Survival rates are poor, usually less than 2 years.
