Pelvic exenteration for recurrent or persistent gynecologic malignancies: Clinical and histopathologic factors predicting recurrence and survival in a modern cohort.

ABSTRACT:

Objectives

To explore pre-operative factors and their impact on overall survival (OS) in a modern cohort of patients who underwent pelvic exenteration (PE) for gynecologic malignancies.

Methods

A retrospective review was performed for all patients who underwent a PE from 1/1/2010 through 12/31/2018 at our institution. Inclusion criteria were exenteration due to recurrent or progressive carcinoma of the uterus, cervix, vagina or vulva, with histologically confirmed complete surgical resection of the malignancy. Exclusion criteria included PE for palliation of symptoms without recurrence, and for ovarian or rare histologic malignancies. Univariable and multivariable analysis were performed to identify factors predicting prolonged survival.

Results

Overall, 71 patients met the inclusion criteria. Median age at time of exenteration was 62 years (range, 28-86 years). Vulvar cancer was the most common primary diagnosis (32%); 30% had cervical cancer; 23%, uterine cancer; 15%, vaginal cancer. Median OS was 55.1 months (95% confidence interval (CI): 36-not estimable) with a median follow-up time of 40.8 months (95% CI: 1-116.1). On univariable analysis, age > 62 years (hazard ratio (HR) 2.71, 95% CI 1.27-5.79), American Society of Anesthesia (ASA) 3-4 (HR: 3.41 (95% CI 1.03-11.29), and vulvar cancer (HR 4.19 (95% CI 1.17-14.96) predicted worse OS. Tumor size and prior progression-free interval (PFI) did not meet statistical significance in OS analyses. On multivariable analysis, there were no significant factors associated with worse OS.

Conclusions

PE performed with curative intent may be considered a treatment option in well-counseled, carefully selected patients, irrespective of tumor size and PFI before exenteration.

Project description:ObjectiveTo examine changes in performance and outcomes of pelvic exenteration for gynecologic malignancies.MethodsThis is a population-based retrospective study examining the Nationwide Inpatient Sample between 2001 and 2015. Women with cervical, uterine, vaginal, and vulvar malignancies who underwent pelvic exenteration were examined. Comorbidity, perioperative complications, total charges, length of stay, and mortality were assessed.ResultsThere were 2647 cases included. Cervical cancer was the most common malignancy (45.1%), followed by vaginal cancer (27.6%). 26.9% of women had a Charlson Comorbidity Index ≥3, which significantly increased from 23.3% in 2001-2005 to 33.3% in 2011-2015 (42.9% relative increase, P < 0.001). Obese women undergoing exenteration increased significantly from 4.5% in 2001-2005 to 19.4% in 2011-2015 (3.3-fold relative increase, P < 0.001). The perioperative complication rate was 68.1%, including 38.7% with multiple complications. The mortality rate was 1.9%. The number of women with multiple perioperative complications increased from 29.4% in 2001-2005 to 52.8% in 2011-2015 (78.6% relative increase, P < 0.001). More recent year of surgery, obesity, higher comorbidity, higher household income, surgery at large bedsize hospital, urinary diversion, vaginal reconstruction, and vulvar cancer were associated with an increased risk of multiple complications on multivariable analysis (all, P < 0.05). Median length of stay was 14 (IQR 9-21) days, and the number of women hospitalized ≥28 days significantly increased from 12.6% in 2001-2005 to 19.1% in 2011-2015 (51.6% relative increase, P < 0.001). The median corrected total charges increased from $121,854 to $185,100 between 2001 and 2015 (net difference +$63,246, 51.9% relative increase, P < 0.001).ConclusionWomen undergoing pelvic exenteration for gynecologic malignancies became more obese and comorbid during the study period. Pelvic exenteration for women with gynecologic malignancies is associated with high morbidity and mortality as well as substantial treatment-related costs.

Project description:BackgroundPelvic malignant tumors often originate in the rectum, bladder, uterus, and other organs. In patients with locally advanced tumours in the presence of direct invasion of one or more organs, negative tumor resection margin (R0) resection can be very beneficial to patient survival if it can be performed. As a multidisciplinary and high-risk surgical method, the pelvic exenteration (PE) procedure has only been reported in a few medical centres internationally. We retrospectively analyzed the clinical data of patients who had undergone PE surgery in our hospital, in order to provide ideas for the best treatment of patients with pelvic malignant tumors.MethodsA retrospective analysis was conducted of 59 patients with pelvic malignant tumors admitted to the Affiliated Cancer Hospital of Zhengzhou University from January 2015 to July 2021, all of whom received PE surgery. They were divided into two groups according to the location of the disease: the rectal cancer group (n=40) and the cervical cancer group (n=19). Statistical analysis was performed on the baseline and follow-up data of the two groups of patients.Results(I) Patient baseline data. Compared to the rectal cancer group, more patients in the cervical cancer group received preoperative radiotherapy and chemotherapy (P=0.013), and had a lower R0 resection rate (P=0.037). Postoperative complications in patients with rectal cancer and cervical cancer were 27.5% and 47.3%, respectively. (II) Patient survival analysis after PE surgery. The 5-year survival rate was 36.6% in the rectal cancer group and 25.3% in the cervical cancer group. In the rectal cancer group, for the primary tumor, if there was no lymph node metastasis or no postoperative complications in the postoperative pathology, the patient had a good survival prognosis. Univariate analysis showed that recurrent rectal cancer, postoperative lymph node metastasis, postoperative complications, and microsatellite stability (MSS) were significant predictors of poor survival outcomes. Multivariate analysis showed that lymph node metastasis and postoperative complications were independent prognostic factors for patient survival.ConclusionsPE is a viable option for pelvic malignancies; aggressive radical resection of lesions and reduced postoperative complications can effectively improve patient outcomes.
