[Does the pelvic nodes dissection for the rectal cancer patients make any contribution to the end-results of surgery?].
Extended pelvic nodes dissection (PND) was adopted to 182 curatively resected rectal cancer patients from 1978 to 1986 at Kinki University Hospital. All patients were diagnosed preoperatively that the depth of cancer invasion were the proper muscular layer or more. Dissected lymph nodes were examined in detail by the clearing method. Pelvic nodes involvement was found in 19 patients or 10.3% out of 182 with PND, and 5-year survival of 19 patients was 26.3%. All over 5-year survival of 182 patients with PND was 69.0% while 62.2% without PND before 1978. There was no significance in the rates of local recurrence between 13.2% with PND and 13.7% without PND. Urinary and sexual dysfunction was increased from 41% and 38% without PND to 66.7% and 88% with PND respectively. It is difficult to evaluate the meaning of PND in the rectal cancer surgery from this non-randomized study. As 80% of the pelvic nodes involvement, however, were found in the cancer with deeper penetration from the muscular layer (a2) and with the location of the middle or lower rectum, PND should be considered only to these two conditions.
