Incidence of Histologically Proven Pelvic and Para-Aortic Lymph Node Metastases and Rate of Upstaging in Patients with Locally Advanced Cervical Cancer: Results of a Prospective Randomized Trial

Background: Surgical staging is associated with a significant rate of upstaging compared to clinical/radiological staging in patients with locally advanced cervical cancer. Objective: To analyze the stage-specific percentage of pelvic and para-aortic lymph node metastases and the upstaging ratio in a prospective randomized trial (Uterus-11). Methods: FIGO stage IIB-IVA cervical cancer patients were randomized to surgical staging (arm A) or to clinical staging and primary chemoradiation (arm B). Arm B patients underwent CT-guided biopsy of suspicious para-aortic lymph nodes. Confirmed para-aortic metastasis patients received extended-field radiation therapy. Results: A total of 234 patients were enrolled, including 120 (arm A) and 114 (arm B) treated per protocol. The groups were well balanced. Pelvic and para-aortic lymph node metastases were identified after surgical staging in 51 and 24% of patients, respectively (p p Conclusion: The histological results in both groups led to a considerable rate of upstaging. Oncological data from the Uterus-11 study may reveal whether modified therapy translates into a survival benefit.
