BACKGROUND: In September of 2024, the 2nd annual meeting of the Strategic Advances in Sarcoma Science (SASS) convened at the National Institutes of Health. This gathering of national sarcoma experts focused on preclinical studies, clinical trials, opportunities, challenges, and future directions in sarcoma biology and clinical care with a focus on immunotherapy. The Immunology in Sarcoma breakout group conducted a dedicated discussion focused on the current and future implementation of adoptive cellular therapies (ACTs) in sarcomas. The current manuscript summarizes these discussions and provides a comprehensive resource for researchers and clinicians. RESULTS: Adoptive cell therapy (ACT) has shown encouraging results in sarcomas with afami-cel achieving durable responses in synovial sarcoma and early TCR-T trials against NY-ESO-1 and MAGE-A4 demonstrating meaningful response rates. Building on these outcomes will require discovering new targets, selecting optimal cell types, refining conditioning regimens, combining with alternative treatment strategies such as TKIs, and leveraging predictive biomarkers informed by a deeper understanding of the tumor microenvironment. CONCLUSIONS: Sarcomas are promising targets for adoptive cell therapy (ACT), as shown by afami-cel's success in synovial sarcoma, but broader impact requires new target discovery, optimal cell selection, improved conditioning, combination treatments, deeper tumor microenvironment understanding, and predictive biomarkers to achieve more durable responses for more patients.
