Résumé
In selected patients, pelvic exenteration (PE) is curative, but morbidity and mortality are feared. Unfortunately, prerequisites for indicating PE are not generally defined. The aim of the study was to identify prognostic factors for survival after PE in advanced pelvic gynecological malignancies for finding possible prerequisites for the indication of PE. Between 2002 and 2016, 49 patients underwent pelvic exenteration for advanced pelvic malignancies apart from ovarian cancer. Progression-free survival (PFS) and overall survival (OS) were calculated based on the Kaplan-Meier method. Factors significantly affecting 5-year overall survival were identified using multivariate regression analysis. Survival distributions between the best and the worst group were compared by the log rank test. Forty-nine patients with recurrent or primary pelvic gynecological malignancy (20 recurrent disease, 29 primary disease) were included. Seventeen patients had oligometastatic disease at surgical intervention. Resection margin, age, primary versus secondary exenteration and metastatic disease were independent prognostic factors in multivariate regression analysis. A significant difference was observed in 5-year overall survival regarding the best group (57.14%) and the worst group (10%) (p=0.009). Cervical cancer was the only identified risk factor for increased morbidity. Pelvic exenteration is a valuable therapeutic option with most long-term survivors in the group of patients below 63 years, as primary treatment, with clear microscopic margins and no distant metastases. These four factors may serve as valuable prerequisites for the indication of pelvic exenteration as survival and morbidity in this group of patients compares favorably to alternative therapeutic options.

BACKGROUND/AIM
OBJECTIVE
In selected patients, pelvic exenteration (PE) is curative, but morbidity and mortality are feared. Unfortunately, prerequisites for indicating PE are not generally defined. The aim of the study was to identify prognostic factors for survival after PE in advanced pelvic gynecological malignancies for finding possible prerequisites for the indication of PE.
PATIENTS AND METHODS
METHODS
Between 2002 and 2016, 49 patients underwent pelvic exenteration for advanced pelvic malignancies apart from ovarian cancer. Progression-free survival (PFS) and overall survival (OS) were calculated based on the Kaplan-Meier method. Factors significantly affecting 5-year overall survival were identified using multivariate regression analysis. Survival distributions between the best and the worst group were compared by the log rank test.
RESULTS
RESULTS
Forty-nine patients with recurrent or primary pelvic gynecological malignancy (20 recurrent disease, 29 primary disease) were included. Seventeen patients had oligometastatic disease at surgical intervention. Resection margin, age, primary versus secondary exenteration and metastatic disease were independent prognostic factors in multivariate regression analysis. A significant difference was observed in 5-year overall survival regarding the best group (57.14%) and the worst group (10%) (p=0.009). Cervical cancer was the only identified risk factor for increased morbidity.
CONCLUSION
CONCLUSIONS
Pelvic exenteration is a valuable therapeutic option with most long-term survivors in the group of patients below 63 years, as primary treatment, with clear microscopic margins and no distant metastases. These four factors may serve as valuable prerequisites for the indication of pelvic exenteration as survival and morbidity in this group of patients compares favorably to alternative therapeutic options.
