e18658 Background: Adolescent and young adults (AYAs) experience poorer outcomes, including lower survival improvements, compared to younger and older patients. As higher compliance with National Comprehensive Cancer Network (NCCN) guidelines has been associated with improved outcomes, we sought to understand the influence of psychosocial factors on receipt of care concordant with NCCN guidelines in AYAs with bone sarcomas. Methods: Retrospective chart review was performed on adult AYA patients (18-39 years) with localized Ewing sarcoma (ES) or high-grade conventional osteosarcoma (OS) seen at least once between 2015-2019 at the University of Wisconsin (UW). These tumor types were selected given uniform guideline-based care recommendations. Chart review identified receipt of standard care as per NCCN Bone Cancer guidelines, defined as neoadjuvant chemotherapy, local therapy (surgery/radiation), and adjuvant chemotherapy with receipt of at least 75% of recommended chemotherapy cycles, and compared to interpersonal relationships (marital status and presence of children at cancer diagnosis), changes in school or work following cancer diagnosis, substance use, and residential location. Results: We identified 21 AYA patients with localized ES (10/21, 48%) or OS (11/21, 52%), with 67% (14/21) receiving NCCN guideline concordant care. Receipt of guideline concordant care was associated with interpersonal relationships, with only 33% (1/3) of patients with children versus 72% (13/18) of patients without children receiving guideline concordant care. Additionally, the one patient noted to divorce following cancer diagnosis did not receive guideline concordant care (0/1, 0%) as compared with 67% (10/15) of single patients and 80% (4/5) of married patients. Vocational changes also affected care, with only 56% (5/9) of patients with work change following cancer diagnosis receiving guideline concordant care versus 75% (9/12) without work changes. Guideline concordant care was less common in patients with alcohol use (5/10, 50%) as compared with patients without alcohol use (9/11, 82%). Residential distance to UW was also associated with receipt of guideline concordant care, which was more common in patients living 0-20 miles from UW (86%, 6/7) as compared with those 21-100 miles from UW (60%, 6/10) or > 100 miles from UW (50%, 2/4). Conclusions: Given the occurrence of cancer during a complex developmental time, AYAs have a relatively high occurrence of psychosocial changes and needs, which we found to be associated with receipt of NCCN guideline concordant care in patients with localized ES and OS. While a limited sample size, as the first study to define specific psychosocial factors that affect receipt of guideline concordant care, these finding suggest the need to improve identification and support of these discrete patient factors.
