This retrospective cohort study reviewed 70 platinum-resistant recurrent ovarian cancer (PROC) patients who received apatinib plus paclitaxel (apatinib plus paclitaxel group) (N = 32) or paclitaxel monotherapy (paclitaxel monotherapy group) (N = 38). The recommended regimens were as follows: paclitaxel (60 mg/m2) administrated once a week with a maximum of 18 weeks; apatinib (250–375 mg/day) administrated until disease progression or patient intolerance. Interestingly, disease control rate was elevated (84.4% vs. 60.5%, P = 0.028), whereas objective response rate only disclosed an increasing trend (lacked statistical significance) (37.5% vs. 18.4%, P = 0.074) in apatinib plus paclitaxel group compared with paclitaxel monotherapy group. Progression-free survival (median [95% CI]: 5.0 [2.5–7.5] months vs. 3.8 [2.4–5.2] months, P = 0.033) and overall survival (median [95% CI]: 21.1 [13.2–29.0] months vs. 14.8 [11.4–18.2] months, P = 0.032) were both prolonged in apatinib plus paclitaxel group compared to paclitaxel monotherapy group, which were further verified in the multivariate Cox's proportional hazard regression analyses (both P < 0.050). Additionally, the incidence of each adverse event was not different between the two groups (all P > 0.050). Collectively, apatinib plus paclitaxel exhibits better efficacy and acceptable toxicity compared with paclitaxel monotherapy in PROC patients.
Abstract
What Is Known and Objective
Apatinib, an oral antiangiogenic drug, exerts potential anti-tumour effects on platinum-resistant recurrent ovarian cancer (PROC). This study intended to evaluate the efficacy and safety of apatinib plus paclitaxel compared to paclitaxel monotherapy in PROC patients.
Methods
This retrospective cohort study reviewed 70 PROC patients who received apatinib plus paclitaxel (apatinib plus paclitaxel group) (N = 32) or paclitaxel monotherapy (paclitaxel monotherapy group) (N = 38). The recommended regimens were as follows: paclitaxel (60 mg/m2) administrated once a week with a maximum of 18 weeks; apatinib (250–375 mg/day) administrated until disease progression or patient intolerance.
Results and Discussion
Disease control rate was elevated (84.4% vs. 60.5%, P = 0.028), whereas objective response rate only disclosed an increasing trend (lacked statistical significance) (37.5% vs. 18.4%, P = 0.074) in apatinib plus paclitaxel group compared with paclitaxel monotherapy group. Progression-free survival (median [95% confidence interval (CI)]: 5.0 [2.5–7.5] months vs. 3.8 [2.4–5.2] months, P = 0.033) and overall survival (median [95% CI]: 21.1 [13.2–29.0] months vs. 14.8 [11.4–18.2] months, P = 0.032) were both prolonged in apatinib plus paclitaxel group compared to paclitaxel monotherapy group, which were further verified in the multivariate Cox's proportional hazard regression analyses (both P < 0.050). Additionally, the incidence of each adverse event was not different between the two groups (all P > 0.050).
What is New and Conclusion
Apatinib plus paclitaxel exhibits better efficacy and acceptable toxicity compared with paclitaxel monotherapy in PROC patients.
