Evaluation of Indocyanine Green-guided Systematic Pelvic Lymphadenectomy in Endometrial and Cervical Cancer


The lymph nodes involvement is one of the most important prognostic factors in endometrial (EC) and cervical cancer (CC). Indeed, the lymph node involvement in cancer patients modifies the International Federation of Gynecology and Obstetrics (FIGO) stage and plays a pivotal role in the choice of the adjuvant therapy. Since the modern imaging techniques are not yet able to accurately detect lymph nodes metastasis, pelvic systematic lymphadenectomy has still an important role and it still represents the gold standard in EC and CC. The sentinel lymph node (SLN) biopsy, which is a standard practice in breast cancer and melanoma, is often used in some early stage gynaecological cancers such as EC and CC. Indocyanine green (ICG) is the most used tracer for the detection of SLN in gynaecological cancer, especially in laparoendoscopic setting. ICG allows a complete visualization of the lymphatic drainage and, for this reason, it may be used even in systematic pelvic lymphadenectomy to guide the surgeon during the procedure. Several studies have demonstrated an advantage of the ICG-guided lymphadenectomy in other types of cancers, showing a higher number of lymph nodes removed with this technique when compared to standard lymphadenectomy (without ICG). To date, there is no published study about ICG-guided systematic pelvic lymphadenectomy in EC and CC. In this scenario, the aim of this study will be to compare systematic ICG-guided pelvic lymphadenectomy and standard lymphadenectomy in EC and CC.
