Abstract
Simple Summary The impact of the molecular signature on the favorable prognosis of endometrial cancer patients with coexistent adenomyosis is undefined. We aimed to compare the prevalence of molecular groups at poor and intermediate prognosis (p53-abn and MMR-d groups) between endometrial cancer patients with and without coexistent adenomyosis through a multicentric, observational, retrospective, cohort study. We included 147 endometrial cancer patients (38 in the adenomyosis group and 109 in the no adenomyosis group) and we found no significant difference in the prevalence of p53-abn (p = 1.000) and MMR-d (p = 0.2880) signatures between the two groups.
