Identifying the superior surgical procedure for endometrial cancer

摘要

BACKGROUND: Endometrial cancer (EC) is one of the most common gynecologic tumors, with a high incidence in developed countries. Although the overall prognosis is good, some women have invasive tumors, the risk of recurrence, and death is high. The common surgical methods used in EC are total-abdominal hysterectomy (TAH), total-vaginal hysterectomy (TVH), laparoscopic-assisted vaginal hysterectomy (LAVH), and total-laparoscopic hysterectomy (TLH) including both conventional and robotically assisted. METHODS: The literature search was performed in The Cochrane Central Register of Controlled Trials, PubMed, Web of Science, and Embase. The randomized controlled trials (RCTs) will be included. The search date is until June 2019. The risk of bias of included RCTs was assessed by 2 investigators according to the Cochrane Collaboration's tool. Network meta-analysis will be conducted by R software. RESULTS: This study is ongoing and the results will be submitted to a peer-reviewed journal for publication. CONCLUSION: This network meta-analysis will provide clinical staff with current and reliable information on the best surgical approach for EC. Ethical approval is not applicable, since this is a network mate-analysis based on published articles. The protocol has been registered on PROSPERO under the number CRD42019128094.
