Abstract

Objective. To review the frequency, localization, latency and clinical staging of synchronic and methachronic tumors in patients with resected carcinoma of the colon during the period 1979-1989. Setting. A third level hospital in Mexico City. Results. Synchronic tumors. Nine individuals (7.2%) of 123 patients reviewed had synchronic tumors. Their mean age was 63 years (26-78); 4 were men and 5 women. Localization and staging were: transverse colon + sigmoid (B1 + A); both ascendant colon (C2 + A); transverse colon + rectum (B3 + A); both descendent colon (B2 + A); sigmoid + descendent colon (A + A); transverse + descendent colon (B2 + B2); ascendent + sigmoid colon (D + B2); both sigmoid (B1 + A); ascendent + transverse colon (B1 + B2). In four patients, the presence of the synchronic tumors modified the surgical procedure. Methachronic tumors. Two cases (3.2%) were detected in 61 patients followed more than one year after colonic cancer surgery; the latency times were 16 and 23 months. In one case staging was A and the other was an in situ carcinoma. Conclusions. The frequency of synchronic and methachronic tumors in similar to that reported in the English literature. We emphazise the need to perform routine control colonoscopies preparatively and during the followup of these patients.
