[Report of a family with cancer family syndrome].

A report of multiple primary early duodenal cancer and ileocecal cancer with cancer family syndrome is presented. Analysis of 65 individuals of this family showed 7 large bowel cancers, 1 lung cancer and cancer of the uterine cervix. The characteristics of this family including increased occurrence of adenocarcinoma, especially large bowel cancer, 3 multiple primary malignant neoplasms, early age of onset of cancer and suspicion of autosomal dominant inheritance, satisfy the criteria for the cancer family syndrome. We recommend screening the individuals in this family for early signs of cancer.
