Purpose: We investigated care disparities and associated factors along the segments of adult musculoskeletal tumor (MST) care prior to initiation of treatment. Patients and Methods: This cohort included newly diagnosed MST patients who were referred to Stanford Medical Center for establishing care from July 2020 to April 2024. We investigated the interval from the onset of symptoms to the first appointment with a primary care provider (PCP wait-time), and the interval from first PCP appointment to obtaining the first imaging study (imaging wait-time) and to obtaining biopsy results (biopsy wait-time). Sarcoma consult wait-time was defined as the interval between referral date and consult date. We performed a survey among sarcoma physicians and non-physician staff on the perception of wait-time. Results: Among 402 eligible patients, approximately 38.5% had PCP a wait-time longer than 5 weeks, with young adults and Hispanic patients having the highest rate of such long wait-times. Approximately 20.6% of patients had an imaging wait-time longer than 5 weeks, with young adults having the highest proportion of such long wait-times. In addition, Hispanic (p = 0.02), Black (p = 0.05) and Caucasian (p = 0.02) patients had significantly higher percentages of patients with an imaging wait-time of more than 5 weeks compared to Asians. Approximately 79.3% of patients had a biopsy wait-time longer than 5 weeks, with Black and Hispanic patients having the highest percent of such long wait-times. In addition, compared to public insurance, private insurance was associated with a higher proportion of patients with PCP wait-times, imaging wait-times, sarcoma consult wait-times and biopsy wait-times longer than 5 weeks. The survey responses overwhelmingly indicated that a wait-time of more than 5 weeks was not acceptable. Conclusions: Substantial disparities in MST care related to age group, ethnicity and insurance type existed in multiple segments of the care journey prior to the initiation of treatment. Our study provides insights for practice, research and policy considerations for narrowing sarcoma care disparities.
