Purpose: The aim of this retrospective study was to investigate the anticancer effect and toxicity of weekly administered nab-paclitaxel as a second-line chemotherapy in elderly patients with relapsed squamous non-small-cell lung cancer (NSCLC).
Patients and methods: We retrospectively reviewed the treatment of 42 elderly patients with relapsed squamous NSCLC, who received nab-paclitaxel monotherapy as a second-line treatment from January 2010 to March 2014. A dose of 100 mg/m2 nab-paclitaxel was administered weekly on days 1, 8, and 15, followed by 1 week of rest. The protocol was maintained for at least two cycles.
Results: The overall response rate (ORR) and the disease control rate (DCR) were 21.43% (9/42) and 47.62% (20/42), respectively. The median progression-free survival (PFS) and overall survival (OS) were 6.6 and 10.9 months, respectively. In the subgroup analysis, there was no significant difference in ORR, DCR, PFS, and OS, accounting for the first-line therapy factors (taxane agent, radiotherapy, or surgery). There was a statistically significant difference in DCR for stages III and IV (62.96% vs 20%, P=0.008), but there was no such difference in either PFS or OS. The ORR of 29 patients receiving more than three cycles of treatment was higher than that of those receiving less than three cycles of treatment (31.03% vs 0%, P=0.038), and there was a significant difference in PFS (7.6 vs 4.9 months, P=0.004) and OS (11.7 vs 8.9 months, P=0.002). No hypersensitivity reactions or treatment-related grade 4 adverse events were reported.
Conclusion: Nab-paclitaxel monotherapy administered weekly at a dose of 100 mg/m2 is shown to be an effective and safe regimen for elderly patients with relapsed squamous NSCLC, especially for patients with stage III disease or good performance status.
