Objective:To summarize the effectiveness of Chinese and Western integrative medicine in treating medium and advanced lung cancer,and to provide guidelines for clinical application.Methods:For this metaanalysis, a comparative search of Chinese medicine data in Chinese National Knowledge Infrastructure(CNKI) and Chinese BioMedical Literature Database(CBM) was undertaken to identify articles related to randomized comparative research of Chinese and Western integrative medicine in treating medium and advanced lung cancer between 1996 to 2006.Quality of life(QOL) was estimated using RevMan 4.2 software for data processing, adopting the odd ratio(OR) and the 95%confidence interval(CI).Results:Through meta-analysis of 10 qualified articles,the results were as follows:the merging effectiveness of QOL[OR=3.80,95%CI(2.65,5.47)];the rate of survival[OR=3.44,95%CI(2.04,5.80)];the tumor response rate[OR=1.88,95%CI(1.37,2.58)];the tumor developing rate[OR=0.33,95%CI(0.23,0.48)].Significant differences existed between the Chinese and Western integrative medicine treatment group and the Western treatment group(P<0.01).Conclusions:Chinese and Western integrative medicine treatment of medium and advanced lung cancer has shown to improve patients’ QOL and survival rate;it also can control tumor development in the short term. Objective: To summarize the effectiveness of Chinese and Western integrative medicine in treating medium and advanced lung cancer, and to provide guidelines for clinical application. Methods: For this metaanalysis, a comparative search of Chinese medicine data in Chinese National Knowledge Infrastructure (CNKI) and Chinese BioMedical Literature Database (CBM) was undertaken to identify articles related to randomized comparative research of Chinese and Western integrative medicine in treating medium and advanced lung cancer between 1996 and 2006. Quality of life (QOL) was estimated using RevMan 4.2 software for data processing , the odds ratio (OR) and the 95% confidence interval (CI). Results: Through meta-analysis of 10 qualified articles, the results were as follows: the effectiveness of the QOL [OR = 3.80, 95% CI , The rate of survival [OR = 3.44, 95% CI (2.04, 5.80)]; the tumor response rate [OR = 1.88, 95% CI (1.37, 2.58) 0.33, 95% CI (0.23, 0.48)]. Significant differenc es existed between the Chinese and Western integrative medicine treatment group and the Western treatment group (P <0.01) .Conclusions: Chinese and Western integrative medicine treatment of medium and advanced lung cancer has shown to improve patients’ QOL and survival rate; it also can control tumor development in the short term.
