Improved Survival in Young Women With Colorectal Cancer

Abstract

This study demonstrated an opposing effect of gender on overall and cancer-specific survival at either side of the age of 50 yr. The protective effect of estrogen on CRC may be an important factor. Women had a greater proportion of emergency surgery, which was related to the predominance of proximal cancers in this gender. Women also had more proximal cancers, thereby limiting flexible sigmoidoscopy as a screening test.
