A retrospective analysis of cisplatin, pemetrexed, and bevacizumab in previously treated non-small-cell lung cancer

Patients with non-small-cell lung cancer (NSCLC) often have an advanced disease when firstly diagnosed. Bevacizumab is a monoclonal antibody against vascular endothelial growth factor receptor (VEGFR). In this study, we retrospectively analyzed the efficacy of cisplatin, pemetrexed, and bevacizumab in previously treated advanced NSCLC. Results showed that the objective response rate(ORR) of this novel regimen is 43%, median progression-free survival (PFS) was 5.2 months (95% CI, 3.7 to 6.7 months) and median overall survival (OS) was 11.4 months (95% CI, 8.8 to 13.9 months). Adverse events were generally mild, ranging from grade 1 to grade 3. In conclusion, the combination of cisplatin, pemetrexed, and bevacizumab obtained promising results in selected patients with NSCLC. Randomized clinical trials are needed to further investigate the efficacy of this regimen.
