This group of patients was similar

to the first one for age, sex and highness. Only 10 of these patients could be studied both pre- and postoperatively (table 3 and 4). 10 patients submitted to high dose preoperative chemoradiation were studied to evaluate the effect of this treatment on sexual function (table 5 and 6).
