The sentinel node in pelvic gynaecological tumors: an updated view

The sentinel lymph node (SLN) refers to the first lymph node susceptible to being affected, due to the lymphatic drainage of a primary tumor. The lymph node involvement in cancer patients is one of the main prognostic factors. Without affecting the prognosis at any time, the SLN seeks to reduce the morbidity associated with lymphadenectomy, reducing surgical time, reducing intraoperative and postoperative complications, such as lymphedema or neuralgia and costs associated with conventional surgery.

With this review we intend to make a close and current view of the use of this technique in malignant tumors of the female genital tract
