Abstract
OBJECTIVE: To evaluate real-world use and outcomes of apatinib treatment in platinum-resistant recurrent epithelial ovarian cancer. METHODS: This is an observational study. Patients with platinum-resistant recurrent epithelial ovarian cancer initiating apatinib treatment from January 2016 to December 2018 were included. The primary end point was progression-free survival. Other end points included overall survival, objective response rate, disease control rate, and toxicity. RESULTS: A total of 28 platinum-resistant epithelial ovarian cancer patients were enrolled in this study. Thirteen cases received apatinib as maintenance therapy following chemotherapy with a median progression-free survival of 6.0 months and a medium overall survival of 11.0 months. Four patients received apatinib as palliative following chemotherapy with 2 cases in progressive disease and 2 cases in stable disease. Eleven cases received apatinib alone as salvage therapy with a disease control rate of 81.8% and a median progression-free survival of 3.0 months. The most common adverse effects were hand-foot syndrome (53.57%), secondary hypertension (46.43%) and fatigue (14.29%). Five patients discontinued treatment due to grade 3 toxicities and 4 patients required dose reduction because of adverse effects. CONCLUSION: Apatinib produced moderate improvements in progression-free survival in patients with platinum-resistant epithelial ovarian cancer both as maintenance therapy following chemotherapy and as single-agent salvage therapy. Our study suggests that apatinib may be effective for women with platinum-resistant recurrent epithelial ovarian cancer.
