Abstract:

The main metastasis method of vulvar cancer is lymph node metastasis. The 5-year survival rate of patients with lymph node metastasis is only 25%~41%, which seriously affects the prognosis of patients. However, due to the large scope and trauma of inguinal lymph node dissection, it also brings high postoperative complications such as lymphedema, lymphocysts, delayed wound healing, etc., especially the long-term lower extremity lymphedema, which is the most serious long-term complication, affecting the postoperative follow-up treatment, quality of life and even the prognosis of patients. The inguinal sentinel lymph node is the first stop of lymph node metastasis in vulvar cancer, and it is the most meaningful lymph node in pathology. If there is no metastasis in the sentinel lymph node, it can be considered that the posterior lymph node has no metastasis. Sentinel lymph node biopsy can thereby reduce surgical trauma, reduce the scope of surgery, reduce the risk of postoperative complications, and improve the quality of life.
