Patients and Methods: We conducted a retrospective comparison of the results of PAN dissection versus non-dissection for endometrial carcinomas with macroscopic metastatic lesions beyond the uterus (without significant swelling of the regional lymph nodes, including PAN), whose lesions were completely resected. Results: Disease-free survival and overall survival did not exhibit a significant difference between the two groups. Multivariate Cox proportional hazards analysis demonstrated that PAN dissection was not an independent prognostic factor for survival. The frequency of PAN involvement at the first recurrence did not differ between the two groups. Conclusion: For advanced endometrial carcinomas with macroscopic metastatic lesions beyond the uterus, without significant swelling of regional lymph nodes, PAN dissection may be omitted without a significant adverse effect on prognosis and survival. %U https://ar.iiarjournals.org/content/anticanres/31/12/4513.full.pdf
