RESUMEN

Aim: Vascular endothelial growth factor receptor inhibitors (VEGFRIs) have been common used for recurrent ovarian cancer (ROC), but insufficient high-level evidence on verifying its efficacy and safety. Methods: Randomized controlled trials (RCTs) were searched under eight electronic databases. Stata 14.0 and Review Manager 5.3 were used for data analysis. Certainty of the evidence was assessed using the GRADE profiler. This systematic review (SR) was registered under INPLASY (INPLASY202120019). Conclusion: Totally 23 RCTs involving 2810 patients were included in this SR. Current evidence revealed that VEGFRIs had better efficacy, survival and quality of life in the treatment of ROC. Though VEGFRIs increase some drug-related adverse events (AEs), all the AEs could be manageable in the clinical practice.

The expression of VEGF/VEGF receptors (VEGFRs) in ovarian cancer (OC) tissue was found to be higher than in benign or normal ovarian tissue. Therefore angiogenesis inhibitors play an essential role in OC treatment. Many anti-angiogenic agents have been developed in recent years. The role of small-molecule inhibitors of VEGFRs for recurrent OC (ROC) has demonstrated significant antitumor efficacy. These drugs include Nintedanib, Axitinib, Pazopanib, Sorafenib, Vandetanib, Sunitinib, Cediranib, Ramucirumab and Apatinib, and more are in the way. However, insufficient high-level evidence from systematic reviews (SRs) focused on VEGFRIs for ROC. Therefore, we performed an SR to investigate the efficacy and safety of VEGFRIs for patients with ROC. This SR was registered under INPLASY (INPLASY202120019). Totally 23 RCTs involving 2810 patients were included in this SR. The results indicate that VEGFRIs have better efficacy and survival in the treatment of ROC. Though VEGFRIs increase some drug-related adverse events, all the adverse events could be manageable in clinical practice.
