Study of Concurrent Pemetrexed, Cisplatin and Radiotherapy in Local Advanced Non-Small Cell Lung Cancer

This study was conducted to explore the feasibility of concurrent chemoradiation therapy with pemetrexed, cisplatin and radiotherapy in unresectable local advanced non-small cell lung cancer. We will perform the dose escalation of pemetrexed to determine if full dose (500mg/m2) of pemetrexed could be administrated concurrently with cisplatin and conventional dose radiotherapy (66Gy) firstly. Secondly, radiation dose will be escalated to determine the maximum tolerated dose (MTD) of radiotherapy when administered concurrently with full dose pemetrexed and cisplatin.
