Abstract

Carboplatin plus nanoparticle albumin-bound paclitaxel (nab-PTX) is one of the available first-line treatments for non-small cell lung cancer (NSCLC) patients. However, the efficacy of carboplatin plus nab-PTX as second-line, remains unknown. We examined the efficacy of carboplatin plus nab-PTX after cisplatin plus pemetrexed in non-squamous NSCLC patients. We retrospectively reviewed advanced non-squamous NSCLC patients who received carboplatin plus nab-PTX as a second-line chemotherapy regimen after cisplatin plus pemetrexed in our hospital between March 2013 and December 2017. We assessed clinical characteristics, efficacy, and toxicities. Forty-four patients were recruited. The overall response rate (ORR) was 29% and the disease control rate (DCR), 69%. The median progression-free survival (mPFS) was 3.7 months (95% CI: 2.4-5.5 months) and the median overall survival, 16.6 months (95% CI:8.8-19.5 months). We assessed the ORR and mPFS using the best overall response in the prior regimen. The ORR and mPFS were better in the PD group (ORR; 44% and mPFS: 5.6 months). Carboplatin plus nab-PTX after cisplatin plus pemetrexed in non-squamous NSCLC patients is a treatment option. There were several cases where cisplatin plus pemetrexed was not effective, but Carboplatin plus nab-PTX was.
