Clinical Research of S-1 Versus Pemetrexed in the Maintenance Treatment of Advanced NSNSCLC

The First Affiliated Hospital with Nanjing Medical University120 enrolled

Overview

The purpose of this study is to compare the curative effect of oral S-1 with Pemetrexed in the maintenance treatment of advanced non-squamous non-small cell lung cancer (NSCLC), and initial to explore a new treatment strategy for advanced non-squamous NSCLC.

S-1 consists of Tegafur,Gimeracil and Oteracil Potassium. Tegafur is metabolize to Gimeracil，and slows down the metabolism of 5-FU in high DPD enzyme expression tumor cell, so that 5-FU could bring the antimetabolic fiction more efficiently. Plenty of studies support that S-1 shows a desirable effect on advanced non-squamous NSCLC, and S-1 is more convenient compare with Pemetrexed. The curative effect of Pemetrexed in the maintenance treatment of advanced non-squamous NSCLC has been proved to be valid. The purpose of our study is to explore whether S-1 could replace Pemetrexed in the maintenance treatment of advanced non-squamous NSCLC.
