Sentinel Lymph Node Assessment in Endometrial Cancer: A Review.

Simple Summary: Sentinel lymph node assessment is becoming a standard of care procedure in patients with surgically treatable endometrial cancer due to its cost-effectiveness and the advantages it offers in guiding post-operative management. Unlike in breast cancer, however, several key aspects regarding this technique's employment in endometrial cancer remain unclear, such as tracer injection volume and final pathology interpretation. The aim of this paper is to investigate the current literature on this technique in order to provide simple and clear insight on the matter and to facilitate the reproducibility of this technique, ultimately resulting in improving patients' oncological outcomes. As the number of patients diagnosed with endometrial cancer rises, so does the number of patients who undergo surgical treatment, consisting of radical hysterectomy, bilateral salpingo-oophorectomy, and bilateral pelvic lymphadenectomy or lymph node sampling. The latter entail intra- and post-surgical complications, such as lymphedema and increased intra-operative bleeding, which often outweigh their benefits. Sentinel Lymph Node (SLN) sampling is now common practice in surgical management of breast cancer, as it provides important information about the disease without jeopardizing surgical radicality and patient outcomes. While this technique has also been shown to be feasible in patients with endometrial cancer, there is little consensus on several aspects, such as tracer injection volume and site, pathological ultrastaging, and result interpretation. The aim of this review is to analyze the current literature on SLN assessment in order to help standardize the procedure. [ABSTRACT FROM AUTHOR]
