ABSTRACT
Patient-derived cancer organoids hold great potential to accurately model and predict therapeutic responses. Efficient organoid isolation methods that mini- mize post-collection manipulation of tissues would improve adaptability, accu- racy, and applicability to both experimental and real-time clinical settings. Here we present a simple and minimally invasive fine-needle aspiration (FNA)-based or- ganoid culture technique using a variety of tumor types including gastrointes- tinal, thyroid, melanoma, and kidney. This method isolates organoids directly from patients at the bedside or from resected tissues, requiring minimal tissue processing while preserving the histologic growth patterns and infiltrating im- mune cells. Finally, we illustrate diverse downstream applications of this tech- nique including in vitro high-throughput chemotherapeutic screens, in situ im- mune cell characterization, and in vivo patient-derived xenografts. Thus, routine clinical FNA-based collection techniques represent an unappreciated sub- stantial source of material that can be exploited to generate tumor organoids from a variety of tumor types for both discovery and clinical applications.
