Oxaliplatin-based combination chemotherapy is still effective for the treatment of recurrent and platinum-resistant epithelial ovarian cancer: results from a single center.

Abstract：

BACKGROUND:Combination paclitaxel and carboplatin is currently a first-line regimen for ovarian cancer. However, many patients develop tumor recurrence or drug resistance to this regimen. The study aims to investigate the effectiveness and safety of an oxaliplatin + epirubicin + ifosfamide regimen for the treatment of recurrent and drug-resistant epithelial ovarian cancer. METHODS:A retrospective analysis of 73 patients with recurrent and drug-resistant ovarian cancer was performed; 38 cases of them received oxaliplatin + epirubicin + ifosfamide regimens (IAP group), 35 patients received non-oxaliplatinbased chemotherapy regimens (control group). The therapeutic effects and side effects of the oxaliplatin + epirubicin + ifosfamide regimen were analyzed and summarized. Kaplan-Meier survival curves and Cox proportional hazards regression were used to compare progression-free and overall survival between the two groups. RESULTS:Of the 38 patients in the IAP group, 14 patients (36.84%) achieved complete remission, 12 (31.58%) achieved partial remission, 2 (5.26%) achieved stable disease and 10 (26.32%) developed progressive disease. The overall effective rate (complete or partial remission) of the IAP regime was 68.42%. While, of the 35 patients in the control group, 12 patients (34.29%) achieved complete remission, 3 (8.57%) achieved partial remission, 5 (14.29%) achieved stable disease and 15 (42.86%) developed progressive disease. The overall effective rate was 42.86%, which was lower than that in the IAP group (P = 0.035, χ(2) = 4.836). Progression-free survival was 9.5 months (0-64 months) in the IAP group vs. 3 months (0-74 months) in the non-oxaliplatin group (P = 0.014 by Kaplan-Meier survival curves; HR = 2.260; 95%CI 1.117-4.573; P = 0.023 by Cox proportional hazards regression). Median overall survival was 46 months (9-124 months) in the IAP group vs. 35 months (9-108 months) in non-oxaliplatin group (P = 0.018 by Kaplan-Meier survival curves; HR = 2.272; 95%CI 1.123-4.598; P = 0.022 by Cox proportional hazards regression). In IAP group, 15.79% (6/38) of the patients suffered grade III-IV bone marrow arrest. The main non-hematological side effects of the IAP regimen included nausea and vomiting (21.05%, 8/38), peripheral neurotoxicity (15.79%, 6/38) and hepatic or renal lesions (2.63%, 1/38). The main side effects of the two chemotherapy regimens showed no statistical difference. CONCLUSION:The oxaliplatin-based IAP regimen is potentially effective for salvage chemotherapy in patients with recurrent and drug-resistant ovarian cancer, with a better therapeutic effect and tolerable side effects.
