Since 1984, we have studied nerve-sparing surgery (NSS) combined with preoperative radiotherapy (XRT) in patients with advanced rectal cancer to preserve the genitourinary function without compromising radicality. The present aim was to evaluate the prognosis and the postoperative genitourinary function.
A total of 167 patients with advanced rectal cancer underwent curative nerve-sparing surgery. Among them, 60 underwent the preoperative therapy using irradiation (42.6 Gy) and tegafur suppository. Survival, local recurrence, and postoperative genitourinary function were investigated in these patients.
The 5-year survival rate was 80.9% and the local recurrence rate was 6.7% in the NSS+XRT group. Almost all of the patients receiving NSS could micturate spontaneously, but preservation of sexual function was not as successful.
Better local control and preservation of urinary function were possible in advanced rectal cancer patients by NSS+XRT.
