e23131 Background: Comparative study results between the efficacies of traditional Chinese medicine (TCM) therapy with Western medicine therapy in the treatment of cancer pain remain controversial. We use the standardized step treatment as a common control to compare the effectiveness of different Chinese medical methods combined with standardized step therapy for cancer pain using a network meta-analysis. Methods: Randomized controlled trials of the effectiveness of various Chinese medical methods and standardized ladder treatments in PubMed, The Cochrane Library, EmBase, Web of Science, CNKI, VIP, and Wan-Fang databases were searched. Stata14.0 and WinBUGS1.4.3 software were used for statistical analysis. Risk ratio(RR) with their 95% confidence interval were estimated as effect size between treatments. Results: Seventy RCTs were included, a total of 6,936 patients with cancer pain, involving five treatments.The results of network meta-analysis showed that there were significant statistical differences between the four Chinese medical methods combined with standardized step treatment and simple standardized step treatment: Chinese medicine orally combined with standardized step treatment vs simple standardized step treatment: RR = 2.60, 95% CI (2.09, 3.30); Chinese medicine external application combined with standardized ladder treatment vs simple standardized ladder treatment: RR = 2.83, 95% CI (2.31, 3.50); acupuncture physiotherapy combined with standardized ladder treatment vs simple standardized ladder treatment: RR = 3.56, 95% CI (1.92, 7.26); Chinese medicine injection combined with standardized ladder treatment vs simple standardized ladder treatment: RR = 2.22, 95% CI (1.63, 3.05). Conclusions: There are significant statistical differences between different Chinese medical methods combined with standardized step treatment and simple standardized step treatment. For patients with cancer pain, standardized step therapy combined with acupuncture physiotherapy or external application of traditional Chinese medicine can be preferred. Due to the lack of existing research, the conclusions of the study need to be confirmed by high quality RCT.
