Forty patients underwent reoperations for the recurred colorectal cancer at the Department of Surgery, Seoul National University Hospital, from January 1976 to December 1985. The results of reoperation for 37 cases with first pathologic report was analysed retrospectively.
The overall postoperative mortality was 5% and the morbidity was 43%. Mortality was 33% after enterastomy, but nil after bypass procedure or exploratory laparotomy or resection. The mean survival time was 19±18 months and median survival time was 14 months. The cumulative 5 year survival rate was 10±6%.
Resection gave significantly better survival figures than the other procedures. After radical resection, mean and median survival times (37±23 months and 30 months) were significantly prolonged.
Disease extent of recurrent tumor was correlated well with survival time. The mean for local recurrence was 48±27 months, while the means for regional and distant recurrence being, 19±13 and 12±10 months respectively.
The authors conclude that for these recurred colorectal cancer patients, resection ma" offer the best outlook as regards survival, but recurrent state of the colorectal cancer should be considered.
