[Maintenance chemotherapy using UFT and FT for gynecological malignant tumors. The Gunma Prefectural Society for Study of Chemotherapy for Gynecological Cancer].

The Gunma Prefectural Society for Study of Chemotherapy for Gynecological Cancer made a comparative study on postoperative supplementary chemotherapy including UFT and FT-E for gynecological malignant tumors. The number of cases registered totaled 182, which was broken down into ovarian cancer 53 cases, uterine cervical cancer 89 cases and endometrial cancer 30 cases. Complete cases among them consisted of ovarian cancer 53 cases, uterine cervical cancer 86 cases and endometrial cancer 27 cases for a total of 166 cases. Ovarian cancer was stratified into the completely and incompletely removed cases, uterine cervical cancer into postoperative non-irradiated and irradiated cases and endometrial cancer into the positive metastasis (+) group and negative metastasis (-) group. Then the UFT administration group and FT-E administration group were compared for postoperative survival. There were control groups for both ovarian and endometrial cancer. UFT administration showed a significant improvement in the survival rate (P < 0.05) compared to the FT-E administration group in the cases of ovarian cancer completely removed and the cases of endometrial cancer irradiated after operation. No significant difference was observed between other groups compared. The incidence of side effects was 20.6% (20/97) in the UFT administration group and 3.6% (2/55) in the FT-E group. Neither group showed any serious side effects.
