Impact of sentinel lymph node assessment on the outcomes of patients with advanced endometrial cancer: A meta-analysis
Background:
Sentinel lymph node (SLN) assessment is used to treat early endometrial cancer; however, its application in advanced endometrial cancer remains controversial. Therefore, we assessed the effects of SLN assessment and lymphadenectomy (LND) on the prognosis (survival rate and primary outcome) of patients with advanced endometrial cancer.
Methods:
Pertinent studies were selected from PubMed, Embase, Web of Science, and the Cochrane Library until March 19, 2022. Relevant studies were strictly screened according to the inclusion and exclusion criteria. Data from the included studies were extracted and their quality was evaluated. Then RevMan5.4 software was used for the meta-analysis.
Results:
Four retrospective studies were included, which enrolled 7181 patients; 492 were treated with SLN and 6689 with LND. In terms of overall survival, there was no significant difference between the 2 groups (odds ratio = 1.14, 95% confidence interval: 0.92–1.41, I
2 = 0%, P = .39).
Conclusions:
SLN assessment is an alternative to LND as a treatment modality for advanced endometrial cancer.
