Demographics, pathologic patterns and long-term survival in operable colon cancers: local experience in Pakistan.

Abstract

Colon cancer in Pakistan commonly presents at an advanced stage, there is a male preponderance, and relatively mean younger age at presentation for males is seen. Advanced stage and lymph node involvement along with poorly differentiated pathology, signet ring or mucinous morphology, location in descending colon, positive surgical margins and removal of less than twelve lymph nodes are factors associated with poor long term survival. There is a need to reinforce information about colon cancer and larger studies from the region are needed to confirm the factors analyzed here.
