Ethnicity and age disparities in Ewing sarcoma outcome

Abstract

This institutional retrospective review studied Ewing sarcomas from 1987–2011. Among 135 patients, 127 (19 Hispanic and 108 white/non-Hispanic) were analyzed (excluding small sample sized groups) finding 15% Hispanic, 85% non-Hispanic, 27% <18 years, 21% >40 years and 1–272 months follow-up (median 41). Age was significantly associated with overall survival (OS) (p = 0.01), whereby <18 years had a higher probability of 5-year survival (OS 61%) than >40 years (OS 37.6%). Ethnicity was marginally statistically significant (OS, p = 0.065); whereby median survival was clinically significant (white non-Hispanic 63 months and Hispanic 23 months). Hispanic ethnicity and older age are independent poor prognostic factors.
