- W2287085364 abstract "7578 Background: To assess the efficacy and safety of bevacizumab-containing regimens in the treatment of advanced, chemotherapy-naive, non-squamous NSCLC on the basis of the two registrative trials (ECOG E4599 trial and BO17704 [AVAiL] trial). Methods: A pooled analysis of the two trials was performed using a random effect model, and the results were summarized as number-needed-to-treat (NNT) and number-needed-to-harm (NNH). The 1-year survival and 6-month progression free rates were assumed as indexes of efficacy, and grade III-IV side effects were assumed as index of safety. Results: One thousand nine hundred twenty two patients were potentially eligible for the pooled analysis, and 1576 patients were included in the final analysis. A large heterogeneity was documented for both 6-month progression free interval (I2 = 88.164%, p = 0.004) and overall survival (I2=73.541, p = 0.052). The absolute risk reduction of 1-year death and 6-month progression were 3.3% (CI-95% = [-6.5]%-13.2%, p = 0.507), with a NNT = 30; and 15.2% (CI-95% = 0.07%-29.6%, p = 0.04), with a NNT = 6 (both in favor of the bevacizumab-containing regimens), respectively. The absolute risk of treatment-related death was 2.4% (CI-95% = 0.8%-3.9%, p = 0.003), with a NNH = 41 against the bevacizumab-containing regimens; that of bleeding was 3.3% (CI-95% = 1.6%-4.9%, p < 0.001), with a NNH = 30; that of hypertension was 6.6% (CI-95% = 4.6%-8.6%, p < 0.001), with a NNH = 15; that of proteinuria was 2.1% (CI-95% = 0.3%-3.8%, p = 0.024), with a NNH = 47; that of neutropenia was 7.3% (CI-95% = 3.2%-11.4%, p < 0.001), with a NNH = 13; that of thrombocytopenia was 1.5% (CI-95% = 0.2%-2.7%, p = 0.021), with a NNH = 66. Conclusions: Adding bevacizumab to standard chemotherapy in the treatment of advanced, chemotherapy-naive, non-squamous NSCLC seems to favor a modest improvement in the main outcomes, with a significant worsening of the safety profile. These data suggest caution in the generalized use of bevacizumab-containing regimens in the treatment of advanced, chemotherapy-naive, non-squamous NSCLC.
