ABSTRACT
BACKGROUND:
Sunitinib, pazopanib, sorafenib, axitinib and bevacizumab are the five recommended antiangiogenic agents in first-line therapy for metastatic renal cell carcinoma (mRCC). Because these drugs underwent simultaneous clinical development, no direct efficacy and safety comparison was ever conducted, thus preventing optimal therapy choices.METHODS:
We performed a traditional and network meta-analysis to evaluate the efficacy and safety of mRCC-recommended first-line antiangiogenic agents. After a systematic review of Medline and Embase up to July 2014, we identified randomized clinical trials (RCTs) evaluating the outcomes of mRCC patients treated with sunitinib, pazopanib, sorafenib, axitinib and bevacizumab as first-line treatment. Endpoints of interest were response rate, progression-free survival (PFS), overall survival (OS), and safety.RESULTS:
We screened 769 abstracts and included nine RCTs with a total of 4282 patients. In the weighted pooled analysis, first-line antiangiogenic agents showed significant improvement in PFS (HR=0.6; 95% IC, 0.51-0.72) and OS (HR=0.85; 95% IC, 0.78-0.93) compared to control (placebo or interferon-alpha2a (INF)). Network meta-analysis showed no significant differences among antiangiogenic drugs in 6-month PFS, 1-year OS, disease control rate and drug-related safety for all-grade hypertension, diarrhea, weight-loss, nausea or anorexia. However, pazopanib showed a lower incidence of fatigue, anemia and hand foot skin reaction.CONCLUSIONS:
This meta-analysis confirms the benefits of first-line antiangiogenic therapy in mRCC, with an improvement in OS. Sunitinib, pazopanib, axitinib and bevacizumab + INF offer similar efficacy but different safety profiles which can help clinicians to better personalize treatment decisions in patients with mRCC.Palabras clave
