Research progress of imaging diagnosis and radiotherapy in para-aortic lymph nodes of cervical cancer
Cervical cancer is one of the most common gynecological malignancies in the world.For cervical cancer,the latest revised International Federation of Gynecology and Obstetrics(FIGO)staging system(2018)includes imaging and pathological evaluation in its staging.On the basis of gynecological examination,the clinical stage of cervical cancer is strictly carried out,and the tumor stage ⅢC1 with pelvic lymph node involvement and the tumor stage ⅢC2 with para-aortic lymph node involvement are newly added.According to the National Comprehensive Cancer Network Clinical Practice Guidelines for Oncology,patients with pelvic/para-aortic lymph node metastasis are candidates for chemotherapy and radiotherapy,not for surgery.However,the current standards for imaging diagnosis and radiotherapy are still controversial.In this review,the imaging diagnosis of para-aortic lymph nodes in cervical cancer and the current progress of radiotherapy are summarized.
