Purpose:To evaluate the efficacy and toxicities of gemcitabine plus cisplatin for patients with relapsed ovarian cancer. Methods:Twenty-eight patients with recurrent ovarian carcinoma received gemcitabine (1000 mg/m~(2)) plus cisplatin (35 mg/m~(2)) on days 1 and 8 of each 21-day cycle. Of 28 patients, sixteen who relapsed within six months of previously platinum-based regimen were platinum-resistant and the other twelve were platinum-sensitive. Results:Of 28 patients, there were 5 (17.9%) complete and 12 (42.9%) partial responses, for an overall response rate of 60.7% (95%CI: 41.7%–79.6%). The median time to progression for objective responders was 5.5 months with a range of 2.5 to 20 months. Median overall survival for all 28 patients was 12.5 months. Among 16 platinum-resistant patients, a 56.3% response rate occurred. The median survival time was 10.5 months. Among 12 platinum-sensitive patients, a 66.7% response rate occurred. The median survival time was 14.5 months. There were leukopenia grade Ⅲ in 35.7%, grade Ⅳ in 17.9%; thrombocytopenia grade Ⅲ in 28.6 %, grade Ⅳ in 14.3% of patients. Conclusions:Cisplatin plus gemcitabine is active in patients with relapsed ovarian cancer. The adverse effects are tolerable. Hematologic toxicities are manageable with dose modifications.

Background and purpose:To evaluate the treatment regimens used for patients with yolk sac tumors of the ovary and prognostic factors in our hospital. Methods:Clinical data for the patients with yolk sac tumors of the ovary were analyzed retrospectively. Patients were divided into four groups: patients in A group received nonsparing surgery and platinum-based chemotherapy; in B group received nonsparing surgery and non-platinum-based chemotherapy; in C group received fertility-sparing surgery and platinum-based chemotherapy; in D group received fertility-sparing surgery and non-platinum-based chemotherapy. 5-year survival rate and prognostic factors were analyzed.Results:The overall 5- year survival rate was 69.2 %. The 5- years survival rates were 81.8 %, 40.0 %, 82.6% and 50.0% for A, B, C and D group, respectively. Platinum-based chemotherapy achieved significant survival benefit (82.4% vs. 44.4%, P0.05). Clinical stage, the size of residual tumor and Platinum-based chemotherapy were the mainly prognostic factors in multianalysis.Conclusions:Fertility-sparing surgery with a postoperative plainum-based chemotherapy should be the ideal modality for the treatment of yolk sac tumors of the ovary. Staging and tumor-reductive surgery were most associated with the prognosis of the patients.
