| Popis: | PURPOSE: An increased incidence of multiple (synchronous and metachronous) colorectal carcinomas has been reported in hereditary nonpolyposis colorectal cancer. This review was undertaken to determine the clinical implications of multiple colorectal carcinomas in hereditary nonpolyposis colorectal cancer. METHODS: A retrospective review of the records of patients in the hereditary nonpolyposis colorectal cancer registry at Roswell Park Cancer Institute who had either synchronous or metachronous colorectal carcinomas was conducted. RESULTS: Twenty-five of 93 patients with documented pathology were found to have multiple colorectal carcinomas. The mean age at diagnosis of the index colorectal carcinoma was 46.7 (range, 28–65) years. There were 7 (7.5 percent) patients with synchronous colorectal carcinomas and 20 (21.5 percent) patients with metachronous colorectal carcinomas. Two of the seven (28.6 percent) patients with synchronous colorectal carcinomas developed a metachronous colorectal carcinoma. In the patients with metachronous colorectal carcinomas, 29 metachronous events were noted: colon (23) and rectum (6). The mean and median time interval for metachronous colorectal carcinomas were 10.9 and 11.8 (range, 1.5–43.8) years, respectively. The mean times to first, second, and third events were 11.7 (range, 1.5–43.5), 7.9 (range, 2.7–18.7), and 12.3 (range, 11.8–12.7) years, respectively. The majority of patients with metachronous colorectal carcinomas did not have stage progression at the diagnosis of the metachronous colorectal carcinomas: 13 patients had lower or same stage at first event, 4 had lower or same stage at second event, and 2 patients had lower stage at third event. Three of 20 patients with metachronous colorectal carcinomas died of their disease. CONCLUSION: Multiple colorectal cancers are common in hereditary nonpolyposis colorectal cancer. Even though stage progression may not be evident at diagnosis of metachronous colorectal cancer, some of these patients will nevertheless die of their disease. |
