  1. Second primary extracolonic cancers in Japanese hereditary nonpolyposis colorectal cancer.

    Article - En anglais

    We examined the occurrence of second primary extracolonic cancers in 1,170 patients with nonpolyposis colorectal cancer who underwent a resection between 1972 and 1994.

    Such cancers occurred more often in cases with hereditary nonpolyposis colorectal cancer (HNPCC) than in those without (11.1% vs. 3.6%, P=0.0286).

    Five HNPCC cases developed 6 cancers in the stomach, endometrium, ovary, and ureter.

    The mean interval between the first and second operation was 66 months (range : 18-153).

    These findings thus indicate the importance of targetted surveillance for any second primary cancers in the upper gastrointestinal, female genital, or upper urologic tract, especially in HNPCC patients.
