Sentinel lymph node dissection (SLND) and biopsy has revolutionized the world of surgical oncology. SLND offers benefits such as decreased risk of lower extremity edema, lower infection rates and reduced blood loss. Many studies have explored the application of SLNB in the context of vulvar and cervical cancers. Evidence has demonstrated that it is a reasonable alternative to complete lymphadenectomy in the appropriate candidate. Furthermore, utilization of different dyes, such as ICG, has resulted in positive outcomes, resulting in shifts in practice. This review explores the current data and best practices for sentinel lymph node mapping and dissection in vulvar and cervical cancers.
