Abstract: Cervical cancer is one of the most common gynecologic malignant tumor，the survival rate of cervical cancer over the past decades hadn′t improved significantly since radical hysterectomy and lymphadenectomy has been the gold standard of operation method. Local recurrence has an important impact on the survival rate of cervical cancer for the moment，especially the patients with pelvic lymph node metastasis. There is evidence supporting that if the local recurrence has been cut down，the survivals will be improved. Laterally extended parametrectomy （LEP） can remove more lymphatic tissue closed to pelvic wall，which providing an effective surgical treatment among the extended hysterectomy. To provide another efficient operation method，now review the theory，efficacy，controversy and outlook of LEP in the treatment of cervical cancer in this article.
