New responsibilities in the management of colorectal cancer with peritoneal seeding.
The initial dissemination of colon cancer through three routes: the lymphatics, the portal blood, and the peritoneal surfaces.  Dissemination to periotoneal surface may be only superficial contamination of the parietal and visceral peritoneum that may be treatable for cure.  Unfortunately, surgery may have an adverse impact on peritoneal surface dissemination.  Surgical interventions may convert a superficial process into an invasive condition with a greatly reduced prognosis.  In patients with peritoneal seedings, peritonectomy procedures and perioperative intraperitoneal chemotherapy should be performed concomitantly.  By use of a quantitative scoring system, the mass of  cancer present in the abdomen and pelvis at the time of treatment of carcinomatosis correlated directly with survival.  Aggressive treatment of patients with peritoneal carcinomatosis requires consideration in the management of colorectal cancer.
