Failure of scintigraphy lymphatic mapping in endometrial cancer. Causes and solutions.

Aim: To evaluate the effect of technical problems and patient characteristics on sentinel lymph node (SLN) scintigraphic detection and mapping success in early stages of endometrial cancer (EC).

Methods: Patients with clinical early stage EC (IA-IB) underwent SLN mapping using technetium-99m-nanocolloid, between September 2011 and February 2020 were included. There were excluded cases with technical problems, 92 patients were included for the analysis of the diagnostic performance and the relation of mapping failure (pelvic unilateral or not detected SLN) with patient (age, body mass index, previous pelvic disease or surgery) and disease characteristics (histology, grade, myometrial invasion, lymphovascular space infiltration, tumor size, and lymphatic infiltration risk).

A systematic review about the role of preoperative F-FDG PET/CT for prognosis and risk stratification in patients with endometrial cancer.

Objective: To analyse the available literature on the prognostic value of preoperative F-FDG PET/CT metabolic parameters and their usefulness in risk stratification in patients with endometrial cancer (EC).

Material And Methods: Pubmed searches used "(endometr* OR uter*) AND (PET OR FDG)" as keywords from January-2000 to June-2020. References in included articles were checked for possible publications not included in the first search.
