PATIENTS AND METHODS: Patients with recurrent platinum refractory ovarian cancer and with adequate hematologic, renal and hepatic function and an Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 2 were enrolled. The regimen was Gemcitabine 1000 mg/m2 (day 1, 8) and Epirubicin 60 mg/m2 (day 1), the cycle was repeated at interval of 21 days. RESULTS: Twenty eight patients were recruited and received 156 cycles of gemcitabine-epirubicin combination chemotherapy (median 6 cycles). Overall response rate was 42.9% (95% CI equal 24.5 to 62.7) and tumor control rate was 75% (95% CI equal 55.1 to 89.3). No complete responses were observed. Median progression-free and median overall survival times were 7 and 15 months, respectively. The most common grade 3/4 hematological toxicities were neutropenia (57.1%), anemia (10.7%), and thrombocytopenia (7.1%), while the most common grade 3/4 non-hematological toxicities were mucositis (14.3%) and vomiting (3.6%). No treatment related deaths were observed. CONCLUSION: Gemcitabine combined with epirubicin regimen appeared to offer an acceptable clinical profile in patients with recurrent platinum-refractory epithelial ovarian cancer.展开更多
