Colon Cancer in Pregnancy: Report of a Case and Review of the Literature

Abstract

Most colon cancer cases occur in patients over 50 years of age, although about 3% of colorectal cancer patients are younger than 40. During pregnancy the incidence of this neoplasm is estimated to be 0.002%. To date only 32 cases of colonic cancer arising above the peritoneal reflection during pregnancy have been described in the literature. We report another such case, stressing the need for constant alertness on the part of physicians in the presence of abdominal pain and/or distension, a palpable abdominal mass, rectal bleeding and/or weight loss during pregnancy. In fact, the reportedly poorer prognosis of this cancer in pregnant patients is mainly due to the fact that the initial symptoms of the malignancy are usually attributed by the patient, but also by physicians, to normal pregnancy.
