Two groups of patients were formed based on the assessment method of para-aortic lymph node status – radiologic assessment only versus surgical lymphadenectomy. Overall survival was compared with the log-rank test after Kaplan-Meier curves were generated. A Cox model was constructed to control for a priori selected confounders.Results We identified a total of 3540 patients who met the inclusion criteria. Para-aortic staging was performed in 333 (9.4%) patients. These patients were younger (median age 46 vs 52 years, p<0.001), less likely to have co-morbidities (8.7% vs 15.6%, p<0.001), more likely to have private insurance (48.9% vs 37.8%, p<0.001) and receive brachytherapy (76.9% vs 70.9%, p=0.022). The rate of para-aortic lymphadenectomy was comparable between patients with stage IB2-II and III-IVA disease (9.4% for both groups, p=0.98). Patients who underwent para-aortic lymphadenectomy were also more likely to have lymph nodes categorized as positive compared with those who had imaging only (27.3% vs 13.2%, p<0.001). There was no difference in overall survival between patients who underwent radiologic only or surgical para-aortic lymph node assessment (p=0.80 from log-rank test); 4 year overall survival rates were 62.9% and 63%. After controlling for confounders, performance of para-aortic lymphadenectomy was not associated with a survival benefit (HR 1.07, 95% CIs: 0.88 to 1.31).Conclusions In a large cohort of patients with locally advanced stage cervical carcinoma, para-aortic lymphadenectomy was rarely performed and not associated with a survival benefit.Data may be obtained from a third party and are not publicly available.
