Hereditary Colorectal Cancer in Sporadic Colorectal Cancer Care

Abstract

This report is based on a paper read at a symposium of the 13th scientific meeting of Japanese Society for Familial Tumors. Hereditary colorectal tumors are an important medical issue in the study of colorectal cancer. We discussed the condition from the perspective of patients as well as that of medical care providers. Family studies of patients with hereditary colorectal cancer and a registry for these patients are indispensable tools for improving medical care and promoting effective scientific investigations. The current registry systems for hereditary colorectal cancer in Japan are inadequate to supply a base for scientific studies of hereditary colorectal tumors compared with that of European countries. It is an urgent issue for an effective registry system or data base for hereditary colorectal tumors to be established in Japan.
