Summary
Brief summary (as posted)
This is an observational retrospective cohort study to determine metachronous peritoneal carcinomatosis in a specific subgroup of colon cancer patients, those with a final pathologic exam corresponding to pT4 tumors. Based on a sample size calculation of 1152 patients, a retrospective review of a three year period of every participant hospitals, 50 in total, of different characteristics, was stablished.
