The effect of adenomyosis on endometrial cancer: a university hospital-based cohort study
Endometrial cancer (EC) can coexist with gynaecological diseases including adenomyosis which can be defined as the location of endometrial cells within the myometrium. Our aim was to clarify the impact of adenomyosis on the clinical and survival outcomes of EC. We included the patients who underwent an operation for EC and had concurrent adenomyosis in this retrospective cohort study. All clinicodemographical and tumour characteristics with survival outcomes of the patients were analysed comparatively. A total of 763 patients who met the eligibility criteria were included. Of those, 591 patients in the non-adenomyosis group and 172 patients in the adenomyosis group were examined. Disease-specific survival (DSS) was significantly prolonged while progression-free survival (PFS) was not affected by the presence of adenomyosis (
