Although single-drug chemotherapy regimens were used as second-line chemotherapy for advanced lung squamous cell carcinoma (LSCC) patients, there are still no standard guidelines for second-line chemotherapy. The purpose of this study was to compare the efficacy and safety of docetaxel combined with nedaplatin or carboplatin in the second-line treatment of advanced LSCC patients. One hundred and ninety-six LSCC patients receiving docetaxel plus nedaplatin (DN, n = 96) or carboplatin (DC, n = 100) were retrospectively collected until disease progression or unacceptable toxicity. The progression-free survival (PFS), overall survival (OS), objective response rate (ORR), disease control rate (DCR), and adverse events (AEs) were analyzed in the two groups. The ORR was 18.8% versus 16.0%, and the DCR was 39.6% versus 34.0% in DN group and DC group (P > .05 and P > .05), respectively. The PFS was 5.3 versus 3.8 months, and the OS was 8.5 and 6.7 months in DN group and DC group (P = .013 and P = .404), respectively. The rate of digestive reaction and hepatotoxicity was similar in DN and DC groups, whereas more patients in DC group than in DN group suffered from leucopenia (P < .05). Docetaxel combined with nedaplatin is an effective regimen for advanced LSCC patients. Compared with a similar regimen with carboplatin, the response rate was similar; however, nedaplatin regimen shows some superiority as regards survival and some treatment side effect.
