AbstractThe role of lymphadenectomy in the management of early endometrial cancer is still controversial. In the recent ESMO-ESGO-ESTRO guidelines, lymphadenectomy is recommended for patients with endometrioid adenocarcinoma grade 3 with deep myometrial invasion, but complete agreement was not achieved. In Sweden, DNA aneuploidy has been included as a high-risk factor. The aim of our study was to evaluate the impact of tumor histology, FIGO grade, DNA ploidy and myometrial invasion (MI) on occurrence of lymph node metastasis (LNM) in patients with endometrial cancer.The study design is a retrospective cohort study based on prospectively recorded register data. This population-based, nation-wide study in women with endometrial cancer confirms a strong association between MI≥50%, non-endometrioid histology, and FIGO grade 3, respectively and LNM. DNA ploidy should not be included in the pre-operative decision making of removing nodes or not.
