Pelvic Exenteration: An Ultimate Option in Advanced Gynecological Malignancies-A Single Center Experience

Background/Objectives: Pelvic exenteration (PE) might be a curative option for patients with advanced pelvic malignancies. Due to its significant morbidity and mortality rates, PE necessitates meticulous patient selection, and a comprehensive understanding of disease spread. This study outlines the experience at a single tertiary referral center and investigates prognostic factors influencing survival post-PE, thereby guiding clinical decision-making processes. Methods: Patients undergoing PE for advanced pelvic gynecological malignancies between 01/2016 and 12/2023 were retrospectively analyzed using a prospectively managed database. Eligibility for PE was determined through individualized tumor board evaluations based on CT/MRI imaging, excluding patients with distant metastases. Baseline demographic and clinical characteristics, operative details, complication rates, and histopathological findings were assessed using univariate and multivariate regression analyses. Disease-free (DFS) and overall survival (OS) were assessed by Kaplan-Meier analysis. Poor outcome prognostic factors were identified, outlining an optimal candidate profile for PE. Results: A total of 70 patients were included. The median age was 54.5 years. Forty-three patients (61.4%) presented with recurrent disease and the majority were diagnosed with cervical cancer (n = 48, 68.6%). Total PE was performed in 40 patients (57.1%), with complete tumor resection achieved in 68.6% of patients (n = 48). Sixteen patients (22.8%) experienced grade IV/V complications. Median DFS and OS were 8.2 and 16.4 months, respectively. Multivariate analysis identified R1 resection status and para-aortic lymph node involvement as independent negative prognostic factors. Conclusions: PE is a viable option for selected patients with advanced primary and recurrent pelvic gynecological malignancies. When complete tumor resection is feasible, patients may derive benefit from PE, although the risk of severe perioperative complications must be carefully evaluated.
