A Pilot Study of Gemcitabine and Epirubicin Combination Chemotherapy as a Salvage Regimen for Recurrent Platinum Resistant and/or Refractory Epithelial Ovarian Cancer

Abstract

<b>BACKGROUND AND OBJECTIVES:</b> The objective of this study was to assess the antitumor activity and toxicity profile of gemcitabine combined with epirubicin in patients with recurrent platinum refractory ovarian epithelial cancer. <b>PATIENTS AND METHODS:</b> 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. <b>RESULTS:</b> 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. <b>CONCLUSION:</b> Gemcitabine combined with epirubicin regimen appeared to offer an acceptable clinical profile in patients with recurrent platinum-refractory epithelial ovarian cancer
