OBJECTIVE To evaluate the efficacy and adverse effects ofgemcitabine versus pegylated liposomal doxorubicin in patientswith progressive or recurrent ovarian cancer.METHODS We conducted a systematic literature search toidentify all randomized controlled trials comparing gemcitabineand pegylated liposomal doxorubicin for progressive orrecurrent ovarian cancer. Trial data were reviewed and extractedindependently by 2 reviewers. We evaluated the quality of theincluded studies using the Handbook 5.0 recommend standardsand then analyzed data by Cochrane Collaboration's RevMan 5.0.RESULTS Two trials which included a total of 348 patients wereanalyzed. The results of meta-analysis showed that gemcitabineimproved disease control rates significantly better than pegylatedliposomal doxorubicin. A greater number of patients receivinggemcitabine experienced neutropenia compared with patientsreceiving pegylated liposomal doxorubicin; however, hand-footsyndrome and mucositis were more severe in patients receivingpegylated liposomal doxorubicin.CONCLUSION Gemcitabine provided a limited advantagecompared with pegylated liposomal doxorubicin. There existsan urgent need for more high-quality, multicenter, adequaterandomized, controlled clinical trials for comparing gemcitabinewith pegylated liposomal doxorubicin in patients withprogressive/recurrent ovarian cancer.
