Abstract:
Carboplatin plus pemetrexed followed by maintenance pemetrexed is expected to be well‐tolerated by the elderly. This multicenter, prospective study examined the efficacy and tolerability of the regimen in elderly patients with previously untreated advanced non‐squamous non‐small cell lung cancer. Methods The primary endpoint was the 1‐year survival rate, with secondary endpoints of response rate (RR), disease control rate (DCR), progression‐free survival (PFS), overall survival (OS), and adverse event rate. Efficacy was compared between patients with performance status (PS) 0 and 1. Results Forty‐one patients were enrolled between March 2011 and April 2016. Median age was 76.0 years. The 1‐year survival rate was 73% (95% confidence interval (CI), 56‐84%). RR was 44%, DCR was 81%, median PFS was 7.2 months (95%CI, 3.98‐9.20 months), and median OS was 17.4 months (95%CI, 13.60‐22.83 months). Twenty‐one patients (51%) transitioned to maintenance therapy. Toxicities of grade ≥ 3 during the induction phase included anemia (37%), thrombocytopenia (29%), neutropenia (22%), appetite loss (15%), nausea (10%), bacterial pneumonia (7%), febrile neutropenia (5%), and interstitial pneumonia (2%). Treatment was discontinued in two patients with interstitial pneumonia, but no deaths were encountered. During the maintenance phase, one patient needed dose reductions due to phlegmon. No significant difference in efficacy was seen between PS 0 and PS 1. Conclusion Carboplatin and pemetrexed followed by maintenance pemetrexed for non‐squamous non‐small cell lung cancer in elderly patients appear effective and tolerable.
