Design: Retrospective study of 8,953 patients from the National Cancer Database; compared the use of definitive treatment between 2004 and 2014 of 1,280 young adults (YAs, aged 18-39 years); 3,937 patients aged 40-64 years; and 3,756 patients age 65+.
Results: Amputation – 8.1% (YAs), 5.5% (40-64), 5.3% (65+). Chemotherapy – 39.4% (YAs), 29.5% (40-64), 9.3% (65+). Radiation – 59.3% (YAs), 69.1% (40-64), 63.4% (65+). Unique to young adults, clinical stage II disease vs. stage I disease and positive surgical margins were not associated with the use of radiation.
