Abstract
INTRODUCTION: The PARAMOUNT Phase III trial showed that maintenance pemetrexed after pemetrexed plus cisplatin induction was well tolerated and effective for patients with advanced nonsquamous non-small-cell lung cancer. Approximately 17% of patients receiving maintenance therapy in this study were 70 years of age or older. Here we report efficacy and safety results from the PARAMOUNT study for elderly (≥70 years) and non-elderly (<70 years) patients. METHODS: Final efficacy and safety data from the PARAMOUNT study were analyzed post hoc using subgroup analyses for elderly and non-elderly patients. RESULTS:The median age was 73 years in the elderly subgroup (n = 92) and 60 years in the non-elderly subgroup (n = 447). Subgroups had similar baseline characteristics, except for a higher percentage of males and patients with a performance status of one in the elderly subgroup. For elderly patients, the median PFS was 6.4 months for pemetrexed and 3.0 months for placebo; the median OS was 13.7 months for pemetrexed and 12.1 months for placebo. For non-elderly patients, the median PFS was 4.0 months for pemetrexed and 2.8 months for placebo; the median OS was 13.9 months for pemetrexed and 10.8 months for placebo. Elderly patients experienced similar levels of low-grade toxicities, but had a higher percentage of grade 3/4 anemia and neutropenia than non-elderly patients, although importantly, this did not translate into increased febrile neutropenia. CONCLUSIONS: Continuation maintenance pemetrexed had comparable survival and toxicity profiles in the elderly and non-elderly subgroups. However, grade 3/4 anemia and neutropenia were numerically higher for elderly patients.
