About

Cervical cancer is the most common reproductive malignancy in developing country. Due to local invasion, radical hysterectomy cannot be performed in advanced cervical cancer (FIGO IIB - IVA) , so that radiation combined with chemoradiation (RCTX) is a traditional treatment nowadays. Lack of precise treatment strategies, recurrent ratesand metastasisis high ,and the 5-year survival rate is less than 50%. Therefore, it needs to explore a new strategy for improving the prognosis of advanced cervical cancer.

The prognosis of cervical cancer is closely related to its stages ,while the current FIGO clinical stage is too subjective , for example different gynecologic oncologists may give different diagnosis to the same patient. MRI, CT, PET/CT imaging examinations are commonly used as a referrence for clinical staging, but the sensitivity and specificity are not satisfied. In addition, lymph node metastasis significantly impacts the prognosis of cervical cancer . However, the lymph node invasion is not in current staging criteria.

Precision treatment after surgical staging is recommended by NCCN recently .Surgical staging in patients with advancedcervical cancer is safe and does not delay primary RCTX in few randomized study.Whether overall survival benefit the long-term clinical follow-up surgical staging is unknown.Blocking bilateral uterine artery can effectively reduce the tumor size and increase the operability , which has been conformed in locally advanced cervical cancer. Furthermore, ovarian dysfunction caused by RCTX could be avoided by ovarian transposition via surgical staging .

Based on this, we suggesta new surgical stagingfor patients with advanced cervical cancer , which includinglaparoscopic pelvic and para-aortic lymphadenectomy , uterine blood vessel blocking and ovarian transportation, in order to perform individualized postoperative RCTX, reduce tumor load , preserve ovarian function and improve life quality.
