Objective To investigate the curative effect of cisplatin combined with gemcitabine and cisplatin plus pacli-taxel in the treatment of advanced non-small cell lung cancer. Methods All 100 patients with non-small cell lung can-cer in our hospital from January 2012 to January 2014 in our hospital, randomly divided into observation group (gemc-itabine+cisplatin, GP group) and control group (paclitaxel+cisplatin, TP group), each group had 50 cases, two groups of patients every 21 days for a cycle, observed curative effect after 2 cycles, toxic and adverse reaction were compared between the two groups. Results The effective rate of the observation group after treatment was 42.0%(21/50),was higher than that of the control group 40% (20/50), but there was no significant difference (P>0.05). Conclusion Cura-tive effect of cisplatin combined with gemcitabine and cisplatin plus paclitaxel in the treatment of advanced non-small cell lung cancer is similar, the poisonous side effect is different and can be tolerated, for the treatment of advanced non-small cell lung cancer treatment plan better.
