Objective. Bevacizumab/carboplatin/paclitaxel (BEV-CP) combination therapy extends the progression-free survival (PFS) of chemotherapy-naive patients with non-small-cell lung cancer. However, the efficacy and tolerability of BEV-CP therapy in patients with a history of chemotherapy have not been investigated. In the present study, patients receiving BEV-CP therapy at the Nagara Medical Center were divided into 2 groups.
Methods. The first-line therapy (FLT) group consisted of 18 patients who had never received chemotherapy before treatment with BEV-CP, and the non-FLT group included 13 patients who had received other chemotherapy regimens before BEV-CP therapy. The efficacy and tolerability of BEV-CP therapy in the FLT and non-FLT groups were analyzed retrospectively.
Results. The response rate (RR) was 72.2% in the FLT group and 61.5% in the non-FLT group, whereas the disease control rate (DCR) was 83.3% in the FLT group and 92.3% in the non-FLT group. However, neither RR nor DCR was statistically significant between the FLT and non-FLT groups (p=0.40 and 0.43, respectively). The median PFS time was 240 days in the FLT group and 258 days in the non-FLT group, which was not statistically significant (p=0.84). The rate of discontinuation of BEV-CP therapy because of adverse effects was 22.2% in the FLT group and 7.7% in the non-FLT group. The discontinuation rate was lower in the non-FLT group than in the FLT group, but the difference was not statistically significant (p=0.28).
Conclusion. The efficacy and tolerability of BEV-CP therapy as non-FLT and FLT were comparable.
