Sumario:AIM: To determine the therapeutic effect of photodynamic therapy (PDT) for middle-advanced stage upper gastrointestinal carcinomas. METHODS: We searched PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Database from inception to April 2018 for randomized controlled studies. These studies compared PDT with other palliative therapies (radiotherapy, chemotherapy, or Nd:YAG laser) and compared PDT, radiotherapy, or chemotherapy alone with PDT combined with chemotherapy/radiotherapy. In our meta-analysis, both fixed and random effects models were used to estimate the risk ratio (RR) for dichotomous outcomes (the response rate and one-year survival rate). RESULTS: Ten random controlled clinical studies with 953 patients were included in the analysis. The effective rate for PDT was better than that of radiotherapy or Nd:YAG laser for the treatment of middle-advanced upper gastrointestinal carcinomas [RR = 1.36; 95% confidence interval (CI): 1.13-1.65; P = 0.001]. In addition, PDT combined with chemotherapy had significantly better efficacy and a higher one-year survival rate than PDT or chemotherapy alone (significant remission rate, RR = 1.62; 95%CI: 1.34-1.97; P < 0.00001; one-year survival rate, RR = 1.81; 95%CI: 1.13-2.89; P = 0.01). CONCLUSION: PDT is a useful method for the treatment of middle-advanced stage upper gastrointestinal carcinomas. PDT combined with chemotherapy or radiotherapy can enhance its efficacy and prolong survival time.
