KEY FINDINGS: In EC patients with coexistent adenomyosis, the risk of death is halved compared with EC patients without adenomyosis. However, the independence of this association needs to be verified in future studies.
BACKGROUND: Despite the high prevalence of adenomyosis in hysterectomy specimens of endometrial carcinoma (EC) patients, the relationship between adenomyosis and EC prognosis appears unclear. Aim of the study was to assess the prognostic value of coexistent adenomyosis in patients with EC.
DETAILS: A systematic review and meta-analysis was performed by searching six electronic databases for studies reporting data on prognosis of EC patients with and without coexistent adenomyosis. Studies with patient selection based on prognostic factors were excluded. Pooled univariate hazard ratio (HR) analyses for overall survival (OS) and disease-free survival (DRF) were performed, using EC patients without adenomyosis as a control group. For DFS, pooled multivariate HR analysis was also evaluable. Three studies of 2505 EC patients (553 with and 1952 without adenomyosis) were included. Compared with EC patients without adenomyosis, EC patients with coexistent adenomyosis showed a pooled HR of 0.533 (CI 95%, 0.329-0.864) for OS at univariate analysis; 0.536 (CI 95%, 0.334-0.859) for DFS at univariate analysis; and 0.875 (CI 95%, 0.331-2.315) for DFS at multivariate analysis.
