[Extensive and radical surgery for primary ovarian cancer]

From 1983 to 1990, 34 cases of primary ovarian cancer were treated with extensive and radical surgery. Seventeen cases belonged to stage I, 3 cases belonged to stage II and 14 cases were stage III. They consisted of 20 epithelial, 11 germ cell and 2 sex-cord tumors of ovary. The operative method was as follows: infracolic omentectomy, para-aortic and pelvic lymphadenectomy, dilateral salpingo-oophorectomy, total hysterectomy, removing of metastatic implants nd appendectomy. Post surgery, all patients received repeated combination chemotherapy and six cases received irradiation. Four patients underwent the second look operation. The incidence of metastasis of contralateral ovary, omentum, retroperitoneal nodes, uterus, fallopian tubes and appendix were 38.2%, 32.4%, 20.6%, 17.6%, 5.9% and 2.9% respectively. The 3 year survival rate of stage I and II was 92.9%, stage III was 40.0%. The 5 year survival rate of stage I and II was 90.9%, stage III was 50.0%. There was no serious complication both intra and post operation.
