Extraperitoneal Lymph Node Dissection in Patients With Cervical Cancer

Primary Objectives: * To determine the feasibility of performing an extraperitoneal laparoscopic lymphadenectomy in patients with stage IB2-IVA cervical carcinoma who are dispositioned to undergo radiotherapy and concurrent chemotherapy. * To document intraoperative and postoperative complications in patients undergoing extraperitoneal laparoscopic lymphadenectomy. * To determine the rate of lymph node metastases in the para-aortic region in patients with stage IB2-IVA cervical cancer. * To correlate histopathological findings in the para-aortic lymph nodes with preoperative imaging studies (Positron emission tomography (PET) and magnetic resonance imaging (MRI) and computed tomography (CT)).
