Abstract
Background: Pegylated Liposomal Doxorubicin (PLD) could improve the survival rate of patients with recurrent ovarian cancer in previous meta-analysis studies. The aim of the present meta-analysis was to further update the role of PLD in the treatment of recurrent ovarian cancer.Methods: Literature search was performed by using the electronic databases Medicine, EMBASE, Web of Science, and Cochrane library until 27 July 2020. We only restricted the randomized clinical trials. Study specific hazard ratios and 95% confidence level (HR/95% CI), risk ratios and 95% confidence level (RR/95% CI), were pooled using a random effect model. Results: 10 studies (12 trials) were included after screening of 940 articles. We categorized the eligible studies into two groups: the doublet regimens (four trials, 1767 patients) resulted that PLD plus carboplatin(carbo) provided superior progression free survival (PFS) (HR, 0.85; 95% CI, 0.74-0.97) and similar overall survival (OS) (HR, 1.00; 95% CI, 0.88-1.14) compared PAC plus carbo. PLD plus carboplatin was associated with significantly more anemia and Thrombocytopenia, other side effects well-tolerated. In platin resistant patients, the monotherapy regimens (eight trials, 1980 patients) resulted that PLD had similar PFS (HR, 1.02; 95% CI, 0.90–1.16) and OS (HR, 0.88; 95% CI, 0.77–1.01) to other monotherapies. PLD alone was more associated with mucositis/stomatitis and hand-foot syndrome, other side effects well-tolerated.Conclusion: In platinum-sensitive recurrent ovarian cancer, PLD plus carbo is more effective than PAC plus carbo. In platinum-resistant or refractory recurrent ovarian cancer, PLD has similar survival to others monotherapies. For side effects, PLD plus carbo or monotherapy chemotherapy both were well-tolerated.
