Background. The CA031 trial suggested weekly nanoparticle albumin-bound-paclitaxel (nab-PTX) was superior in efficacy to paclitaxel (PTX) once every 3 weeks when combined with carboplatin (CBDCA) for advanced non-small cell lung cancer (NSCLC) patients; a subgroup analysis of elderly patients looked promising. In a multicenter phase II trial, we prospectively evaluated the efficacy and tolerability of modified CBDCA plus weekly nab-PTX for elderly patients with untreated advanced NSCLC. Methods. Eligible patients received CBDCA (area under the curve [AUC] 6 mg/mL/min) on day 1 and nab-PTX (75 mg/m2) on days 1, 8, and 15 every 4 weeks. The primary endpoint was an overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity. Results. Of 32 patients (median age of 78 years), 84% were male, 56% had stage IV NSCLC, and 56% had squamous cell carcinoma. ORR and disease control rates were 50% (95% confidence interval (CI): 33-67) and 94% (95% CI: 85-100), respectively.Median PFS and OS were 6.4 months (95% CI: 4.8-8.0) and 17.5 months (95% CI: 11.9-23.1), respectively. Grade ≥3 toxicities were neutropenia (47%), leukopenia (38%), anemia (34%), thrombocytopenia (25%), and anorexia (9%). Febrile neutropenia and treatment-related deaths were not observed. Conclusion.Modified CBDCA plus weekly nab-PTX demonstrated significant efficacy and acceptable toxicities in elderly patients with advanced NSCLC.
