The best treatment for recurrent granulosa cell tumor(GCT)is considered to be surgical resection, because the effects of chemotherapy or radiation on GCT are obscure. The common site of recurrence is the pelvic cavity, including the surface of the liver and intestine as tumor-dissemination-patterns. Between June 1988 and June 2011, we treated 15 patients with GCT at our hospital. The median follow-up time was 56(22-286)months. Ten patients were stage I, 3 were stage II, and 2 were stage III. No patients had residual lesions at the primary surgery area. Six patients have recurred, and the median disease free survival(DFS)was 85(15-128)months. Six patients had relapses in the pelvic cavity, 2 in the retroperitneal lymph nodes, and 1 in the upper abdomen. Two patients relapsed more than twice; however, the rapid detection of recurrence and surgical resection have kept all patients alive. Thirteen patients have no evidence of disease(NED), 2 are alive with disease(AWD), and no one has died of the disease(DOD). We suggest that maximal debulking surgery to achieve complete cytoreduction of recurrent GCT is the most important treatment for prolonging survival.

We investigated the results of cervical cytology, pathology of colposcopic biopsy and surgical specimen among 765 women suspected to have cervical intraepithelial neoplasia (CIN). Significantly more patients with cervical cytology class III b than class III a were diagnosed in CIN grade 3 on colposcopic biopsy. The concordance rate of colposcopic biopsy and surgical specimen was 79.8%, but we preoperatively diagnosed CIN grade 3 or more at 96.1% with colposcopic biopsy. In time course observation, CIN regressed in 26.3% of all patients, progressed in 19.3% and did not change in 54.4%. Many patients of CIN grade 2 progressed to grade 3 in two years. Significantly more patients of CIN grade 1 or 2 with cervical cytology class III b progressed than with class III a (p0.05).

Although paraaortic lymphadenectomy is one of the standard treatments for gynecological cancer in Japan, it is very invasive so one must examine its safety for patients. Paraaortic lymphadenectomy was performed in 215. Two hundred and fifteen gynecologic cancer patients at our hospital between January 1991 and August 2005. We evaluated operation time, estimated blood loss and the incidence of operative injury, wound complication, and postoperative ileus. It was revealed that the mean operation time was 364 minutes and the estimated blood loss was increased at the operation around the vena cava or renal vein. After we adopted Kocher's technique, the mean blood loss was decreased. The incidence of postoperative ileus was 13.3%, but almost all of the patients were cured within seven days without surgical treatment. The incidence of wound complication was within 10%.

Neoadjuvant chemotherapy (NAC) with intra-arterial infusion was performed in the treatment for 53 patients with advanced cervical squamous cell carcinoma. After NAC with intra-arterial infusion of the anticancer agents including cisplatin via internal iliac artery or uterine artery, 42 patients received radical hysterectomy. The response to therapy was observed in 45 of all patients (84.9%) clinically, and 36 of 42 patients (85.7%) pathologically. Cancer cells disappeared in 11.9% of patients with cervical invasion, 69.2% with vaginal wall invasion and 39.4% with parametrium invasion after NAG. Five-year survival rates were 100% in stage I, 71.5% in stage II, 52.2% in stage II and 0% in stage IV. The group of patients without cancer in the parametrium after NAC showed a significantly better 5-year survival rate than the group with residual cancer in the parametrium. According to the results, the elimination of cancer invasion to the parametrium by NAC is thought to be important for improvement of the prognosis in advanced cervical cancer.
