short review of current implementations of sentinel lymph node mapping in gynecologic cancers.

Lymph node metastasis both increases disease stage and alters adjuvant treatment plans in gynecologic cancers. Since a minority of the patients have nodal metastasis, many patients unnecessarily undergo complete lymphadenectomy and are exposed to the subsequent morbidities. Sentinel lymph node (SLN) mapping is an alternative for evaluation of lymph nodes with lesser side effects. Although it is yet an experimental approach in ovarian cancer, it has been incorporated into guidelines for endometrial, cervical and vulvar cancers. We aimed to summarize the current situation of SLN mapping in gynecologic cancers.
