RESUMO
PURPOSE: Molecular classification of endometrial cancer (EC) has become a promising information to tailor preoperatively the surgical treatment. We aimed to evaluate the rate of lymph node metastases (LNM) in patients with EC according to molecular profile. METHODS: A systematic review and meta-analysis were performed according to PRISMA guidelines by searching in two major electronic databases (PubMed and Scopus), including original articles reporting lymph node metastases according to the molecular classification of EC as categorized in the ESGO-ESMO-ESP guidelines. RESULTS: Fifteen studies enrolling 3056 patients were included. Pooled prevalence LNM when considering only patients undergoing lymph node assessment was 4% for POLE-mutated (95%CI: 0-12%), 22% for no specific molecular profile (95% CI: 9-39%), 23% for Mismatch repair-deficiency (95%CI: 10-40%) and 31% for p53-abnormal (95%CI: 24-39%). CONCLUSIONS: The presence of LNM seems to be influenced by molecular classification. P53-abnormal group presents the highest rate of nodal involvement, and POLE-mutated the lowest.

Sentinel lymph node biopsy has proven safe and feasible in a number of gynecologic cancers such as vulvar cancer, cervical cancer, and endometrial cancer. The proposed aim of lymphatic mapping and sentinel node identification is to decrease the associated morbidity of a complete lymphadenectomy, particularly the rate of lymphedema, while also increasing the detection of small tumor deposits in the node. Different tracers have been shown to be useful, including technetium-99 and blue dye, with a detection reported in 66% to 86%. Recently, there has been increasing interest in the use of fluorescent dies such as indocyanine green (ICG). In this report we provide a review of the existing literature regarding the use of ICG in cervical or endometrial cancer with the goal to provide details on its utility and compare it with other tracers.
