Abstract 2642


Although the clinical efficacy of radiation therapy (RT) has been demonstrated in elderly patients with locally advanced non-small-cell lung cancer (NSCLC), the combination of pemetrexed (PEM) and RT has not been examined in clinical trials yet. Therefore, we conducted a phase I / II study to evaluate the appropriate PEM dose, efficacy and safety of PEM plus RT in elderly patients with locally advanced NSCLC.


Eligibility criteria included performance status (PS) 0-2, aged 71 years or older, pathologically confirmed NSCLC, locally advanced stage (IIIA / IIIB), adequate organ function, and written informed consent. Patients received PEM (500mg/m2 on day1 of a 28-day cycle, 4 course) and RT (total 60 Gy / 30 fractions over 6 weeks). The primary endpoint was objective response rate (ORR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), and adverse events (AEs).


A total of 41 patients (4 patients in phase I, 37 patients in phase II) were enrolled. Median age was 79 years old (range 71-87) and 31 patients were male. Eighteen patients were squamous cell carcinoma, 27 of 41 patients were stage IIIA, and 38 patients were PS 0-1. ORR was 80.5%. Median OS was 24.6 months and median PFS was 6.8 months. There were 2 treatment related deaths, caused by RT pneumonitis in one patient and severe infection in one patient. Common hematological AEs were leucopenia and neutropenia, whereas, common non-hematological AEs were anorexia and constipation. Interstitial lung disease caused by PEM developed in 3 patients. RT related AEs were mainly observed, including radiation esophagitis (grade 1: 22 patients, 2: 6 patients, 3: 1 patient) and RT pneumonitis (grade 1: 11 patients, 2: 14 patients, 3: 7 patients, 5: 1 patient).


This combination treatment shows promising activity, but RT related toxicities were relatively severe. Therefore, the use of this treatment require close caution for elderly patients.
