[Research progress of sentinel lymph node biopsy technique in cervical cancer]

Cervical cancer is the most common gynecological malignant carcinoma in Chinese women, which seriously threatens women's health. Lymph node metastasis is the most important factor affecting the prognosis and adjuvant treatment of patients with early cervical cancer. Conventional systematic lymphadenectomy has always been a reliable method to detect lymph node metastasis. However, this procedure may affect the quality of life of patients because of high risks of complications. Recently, sentinel lymph node biopsy (SLNB) has been researched aiming to assess the status of pelvic lymph node metastasis intraoperatively, avoid unnecessary lymphadenectomy and achieve the goal of individualized diagnosis and treatment. Exploring efficient tracing methods and pathological ultra-staging is the key to the clinical application of SLNB for cervical cancer, and understanding the latest relevant clinical research progress will help SLNB to be applied in the clinic as soon as possible to benefit patients with cervical cancer.
