Synchronous Colorectal Carcinoma

more primary colorectal cancers identified in the same time. Each tumor must be clearly malignant as determined by histological evaluation, geographically separate and distinct. Not infrequently the patients had two or more synchronous colorectal cancers and reported incidence of synchronous cancer was between 2-5% in large series. Resection of synchronous carcinomas might not only increase the patient’s chance of cure, but also avoid second or multiple operations. Despite its importance, a preoperative colonoscopy of the entire colon is often unobtainable due to bowel obstruction by the tumor, poor bowel preparation or limitations associated with available facilities. The aim of this study was retrospectively analyze the patients with diagnosis of multiple cancers and results of en bloc resection for synchronous colorectal cancers in a 10 year period.
