Controversy over sentinel lymph node detection in endometrial cancer

In the last decade, the procedure of sentinel lymph node biopsy has been introduced in low-risk endometrial cancer, being optional in intermediate- and high-risk cancer. However, until the last year, there was no consensus regarding the group of patients to whom to apply it, the best tracer to use or the site of injection. In this paper, we present in a multidisciplinary view the most controversial issues about the sentinel lymph node procedure in endometrial cancer, emphasizing the pros and cons of the different tracers available: radiotracers, hybrid tracers and indocyanine green.
