The International Radiosurgery Research Foundation focuses on funding clinical and translational medical research related to radiosurgery and advanced cancer treatments. Its only recorded grant is a large, targeted research award to a hospital system, suggesting a preference for supporting institutional medical research projects and clinical programs rather than small community nonprofits. While based in Pittsburgh, its giving can be directed to specialized medical centers elsewhere. The foundation appears to prioritize impact on treatment innovation and outcomes over broad service delivery grants.
The International Radiosurgery Research Foundation’s recorded giving centers on a single $100,000 medical research grant in 2023 to Baptist Health South FL in Miami for medical research. That award points to a funder that is built around institutional support for radiosurgery and cancer-related clinical research rather than broad nonprofit programming. Its active grant programs show the same structure: tertiary or quaternary care medical centers can join as associate members, and investigators can submit proposals for new multicenter studies. Those programs place the foundation inside a research network, not a traditional charitable grantmaking model. The foundation’s stated focus areas cover radiosurgery and stereotactic radiotherapy research, clinical cancer treatment and oncology research programs, and hospital-based medical research infrastructure and clinical trials. Beneficiaries are primarily hospital systems, academic medical centers, and clinical researchers, with cancer patients served indirectly through improved treatment development. With annual grants of $100,000 and assets of $894,845, the organization appears to use targeted, institution-level awards to support clinical and translational work in advanced cancer therapies.
In radiosurgery and stereotactic radiotherapy research, the foundation’s grantmaking is tied to multicenter clinical work rather than general philanthropy. Its associate-level membership program is open to tertiary or quaternary care medical centers that want to participate in multicenter clinical trials and research projects. For oncology research, the foundation’s project proposal process supports new multicenter IRRF studies after screening by the Project Review Committee and circulation to members for participation. That process is explicitly built for retrospective and prospective radiosurgery studies and clinical outcomes research. The foundation also supports hospital-based medical research infrastructure. Its only recorded grant, a $100,000 award to Baptist Health South FL for medical research, fits that institutional pattern and suggests support for medical centers conducting advanced treatment research.
The foundation’s typical grant size is fixed at $100,000, with p25, median, and p75 all at $100,000. That points to a highly concentrated grant pattern rather than a broad spread of award sizes. The recorded grant history also suggests a targeted institutional approach: one large award, not a wide set of small grants. Its active programs indicate a recurring research network model. Medical centers can join as associate members, and investigators can submit new multicenter study proposals for review. The foundation does not make grants to individuals and does not make program-related investments.

Highly concentrated giving: single large grant to a medical institution (one-time/isolated in the record) rather than many small or recurring awards; targeted support for institutional research projects.
Notable grantees: Baptist Health South Florida
Grantmaking is regional, with recipients located in the United States in the available data. Florida is the top state by grant count, reflecting the foundation’s strongest giving concentration there. The recorded grant went to Miami, FL, while the foundation’s headquarters are in Pittsburgh, PA. No recipient grants are shown in Pennsylvania in the available record.
Its focus areas are radiosurgery and stereotactic radiotherapy research, clinical cancer treatment and oncology research programs, and hospital-based medical research infrastructure and clinical trials. The active programs also point to multicenter clinical trials, retrospective and prospective radiosurgery studies, and clinical outcomes research.
No. The foundation does not fund individuals, and its active programs are built around medical centers and investigators working on multicenter studies rather than personal awards.
The typical grant size is $100,000. In the available data, p25, median, and p75 are all $100,000, which indicates a single, standardized award level.
Tertiary or quaternary care medical centers can apply for associate-level membership, and investigators can submit proposals for new multicenter IRRF studies. The proposal process is reviewed by the Project Review Committee before being circulated to members for participation.
