Abstract: Cervical cancer is the most common cancer in the female genital system. Para-aortic lymph nodes (PALN) involvement is closely related with treatment and prognosis. Cervical cancer often metastasize to pericervical and parame -trial nodes, internal and external iliac nodes, obturator nodes, and then to common iliac nodes and pre-sacral nodes and fi -nally to PALN and (or) supraclavicular or inguinal lymph nodes. A few patients with cervical cancer had distant lymph nodes metastasis without pelvic lymph nodes involvement. Staging, parametrial invasion and value of Squamous Cell Carcinoma Antigen (SCC) are considered as high risk factors for PALN metastasis. Computed Tomography (CT) is the mostly used im-aging examination to evaluate the lymph nodes metastasis of cervical cancer through measuring the largest diameter of the enlarged lymph nodes and observing the density change of internal part of the lymph nodes. Positron Emission Tomog -raphy (PET) is more sensitive and accurate than CT scan. Surgery is the main management for enlarged PALN not only for therapy but also for diagnosis. Dissection of abdominal extraperitoneal para-aortic lymph nodes and laparoscopical aortic lymph nodes is used widely because of its advantages such as less trauma and less put-off for post-surgical radiation. PALN is one of most common recurrence site of cervical cancer after treatment. Active treatment for recurrence in lymph nodes can improve patient survival.
