The efficacy and safety of radiotherapy combined chemotherapy for laryngeal preservation in advanced laryngeal cancer: A protocol for systematic review and meta-analysis

The appropriate use of surgery or chemoradiotherapy-based approaches for organ preservation has been the subject of much debate. Unfortunately, there has been a lack of improvement in overall survival for patients with laryngeal carcinoma. In this study, we performed a protocol for systematic review and meta-analysis to evaluate the efficacy and safety radiotherapy combined chemotherapy for laryngeal preservation in advanced laryngeal cancer METHODS: This protocol is reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) 2015 statement. We will search the PubMed, Cochrane Library, EMBASE, and Web of Science databases from the inception dates to October, 2022, using the keywords “laryngeal cancer,” “radiotherapy”, and “chemotherapy.” Cochrane “bias risk” tool is used to assess the bias risk of the quality of the included literature. All calculations were carried out with RevMan V.5.3 software. RESULTS: The results of this study will provide evidence for judging whether radiotherapy combined chemotherapy is superior to surgery for treatment of advanced laryngeal cancer. CONCLUSION: This review will provide directions and recommendations for future research and clinical practices of radiotherapy combined chemotherapy for laryngeal preservation in advanced laryngeal cancer.
