Purpose: The aim of this retrospective study was to evaluate the risk of local recurrence such as patients who were treated for Dukes stage B and C low rectal cancer by abdominoperineal resection (APR) or low anterior resection (LAR). Methods:<br>From<br>1985<br>to 1995, 81 patients with low rectal cancers which were within 3∼8 cm from the anal verge were treated by curative resection, 38 by APR and 43 by LAR. The present study examined clinical and tumor characteristics, type of intervention as<br>potential<br>predictors of local recurrence. Retrospective data were analysed by univariate Chi-square tests.<br>Results: Local recurrence was diagnosed in 17 of 81 patients with a median follow-up period of 24 months. The local recurrence rate was 23.6% (9 of 38) after APR and 18.6% (8 of 43) after LAR. There was no difference in local recurrence between<br>patients<br>who had APR and LAR (P=0.58). Also we could not find any significant differences among age (≤65 vs ＞65 years, P=0.53), sex (M vs F, P=0.57), sized of tumors (≤5 vs ＞5 cm, P=0.32), distance from anal verge (≤5 vs ＞5 cm, P=0.57), Dukes stage<br>(B<br>vs<br>C, P=0.22), histological grade (well and moderate vs poorly, P=0.17), distance from distal resection margin (≤2 vs ＞2 cm, P=0.35). Conclusions: The tumor factors such as Dukes' stage were more critical for pelvic recurrences than other patient<br>factors.<br>
