Social determinants of health in uterine carcinosarcoma

Objective. UCS survival outcome disparities by race have been reported. We aimed to investigate social determinants of health (SDOH) and their relation to survival outcomes in women at two affiliated high -volume institutions serving a racially and economically diverse population. Methods. Women diagnosed with stage I -IV UCS treated at St. Paul University Hospital, University of Texas Southwestern (UTSW) Zale Lipshy Pavilion-William P. Clements Jr. University Hospital, and Parkland Memorial Hospital between 1992 and 2022 were eligible. Patients were identified by the local tumor registries; a retrospective study was conducted. The Pearson chi-square test was utilized for categorical variables. OS and PFS were calculated using Kaplan -Meier estimates and compared with the log -rank test. Multivariate Cox models were used to identify independent prognostic factors. All statistical analyses were performed using SAS, version 9.4. Results. Over half of the 218 patients with UCS were NHB. 35% of the patients had stage IV disease. Most HSP and NHB patients had a lower median household income* than Asian/Pacific Islander (API) or NHW (p < 0.001). Stage at diagnosis significantly affected OS (p < 0.001) but not PFS (p = 0.46) in univariate analyses. Accounting for age at diagnosis, insurance, income*, hospital, distance between hospital and home, months from diagnosis to first treatment, stage, and adjuvant therapy, race was significant for OS (p = 0.03) and PFS (p = 0.04). *Median household income by ZIP Code. Conclusions. Racial disparities were seen in median household income. Most SDOH independently analyzed in this study did not affect OS. The complex interaction between race and stage in UCS survival outcomes needs further investigation. (c) 2024 Published by Elsevier Inc.
