Abstract
BACKGROUND: To determine whether there are racial/ethnic disparities in disease presentation, treatment and survival outcomes among children and young adults with chest wall sarcomas. METHODS: The Surveillance, Epidemiology and End Results (SEER) database was analyzed for patients 21 years old and younger with chest wall sarcoma. We performed multivariate logistic regression to investigate the association of race/ethnicity with advanced stage of disease at presentation and likelihood of undergoing surgical resection. Overall survival (OS) was evaluated using Cox regression modeling to calculate hazard ratios with 95% confidence intervals. RESULTS: A total of 669 patients were identified: 393 non-Hispanic whites (NHW) (59%), 151 Hispanics (23%), 64 non-Hispanic blacks (NHB) (11%), and 64 other race/ethnicity (9%). The 5- and 10-year OS rates for the entire cohort were 69% and 64%, respectively. NHB had significantly worse 5-year and 10-year OS compared to NHW based on the log rank test (61% versus 70%, 52% versus 66%, respectively; p = 0.037).). Most patients (80%) underwent surgical resection. However, NHB were less likely than NHW to undergo surgical resection by multivariate analysis (OR 0.43, 95% CI 0.22-0.82). CONCLUSIONS: NHB children and young adults with chest wall sarcoma have decreased overall survival. In addition, NHB are less likely to undergo surgical resection which may contribute to survival disparities. It is paramount that health care providers work to close the treatment gap between racial/ethnic groups to improve survival in children and young adults with chest wall sarcoma. LEVEL OF EVIDENCE: Level III Treatment Study.
