摘      要：A 72-year-old male with an early stage node-negative sigmoid colon cancer developed 2 separate node-negative early stage colon cancers during a subsequent colonoscopy surveillance regimen, the first in the descending colon 7 years later, and the second in the cecum almost 14 years after the first cancer was resected. After the initial symptomatic cancer, all subsequent neoplastic disease, including malignant cancers were completely asymptomatic. This entity, multiple primary cancers, likely reflected the use of a colonoscopic surveillance regimen.
