Background: Management of soft tissue sarcomas often requires coordinated multidisciplinary care including radiation, medical, and surgical oncology. Delays in the multidisciplinary evaluation and treatment may lead to poorer outcomes. Coordination of care through a multidisciplinary clinic (MDC) offering access to all three specialties during the same clinic visit may reduce time from initial evaluation to treatment. Methods: Adult patients treated for soft tissue sarcoma at an NCI-designated comprehensive cancer center following the opening of a sarcoma MDC in November 2021 to May 2023 were included. Patients were either seen in the sarcoma MDC or separately by oncologic providers (usual care). The primary outcome was delay in treatment initiation, defined as greater than 21 days from initial consultation to first treatment. Reasons for delay were abstracted. Descriptive statistics and bivariate analyses were performed. Results: Among 147 patients, 20 were (13.6%) seen in MDC and 127 (86.4%) by usual care. Initial treatments were surgery (46.9%), radiation (30.6%), or systemic therapy (22.4%). Median time to treatment was 34 days (IQR 14-57 days), which differed by treatment modality (surgery 34 days, radiation 37 days, systemic 18 days). There were no significant differences in time to treatment for MDC patients (33 days, IQR 25-44) versus usual care (34 days, IQR 13-57) (p=0.93). However, a significantly higher proportion of MDC patients received multiple modalities of treatment (75.0% vs 48.8% usual care, p=0.011), with a longer average time to treatment in the multi- versus single-modality groups (41 vs 22 days, p<0.001). Among patients requiring multimodal therapy, median time to treatment was 33 days for MDC patients versus 44 days for usual care (p=0.07). MDC patients were also much more likely to receive radiation (90.0% MDC vs 45.6% usual care, p=0.001). Delays in care (n=76, 51.7% of cohort) were seen in 66.7% (12/18) of MDC patients versus 58.3% (63/108) of usual care patients. The most common reasons for delay were need for additional imaging (29.7%) or preoperative testing (18.8%). Conclusions: In this single-center study, no improvement in time to treatment was seen following the opening of a sarcoma multidisciplinary clinic, likely explained by higher proportion of MDC patients receiving multiple treatment modalities. Primary reasons for delay could be anticipated prior to initial evaluation and represent an opportunity for more active case review prior to in-person evaluation to reduce delays in sarcoma treatment.
