title: [Clinico-pathologic study of resection of low rectal cancer with preservation of anus--report of 48 patients].
abstract: Fourty-eight patients suffering from low rectal cancer were treated from 1987-1989 by operation with preservation of anus. Thirty-six similar patients as treated by Mile's operation during the same period served as controls. Follow-up results showed that recurrence developed earlier and in higher frequencies in the former group. The frequencies of recurrence in those with anus preserved were: 1 year 42% (5/12) and 2 years 50% (6/12) whereas those of Mile's operation were: 1 year 3% (1/36) and 2 years 11% (4/36) (P less than 0.01). The 1-year mortality rates also differed conspicuously: former group 17% (2/12) and the latter group 3% (1/36). The authors believe that for lesions of Dukes' B or C stages, pathological moderate or poor differentiation, larger than 4 cm across, deep crater or presence of peri-rectal or lymph node involvement as discovered on exploration should not be treated by resection with preservation of anus.
