TUMOR INSTITUTE RADIATION ONCOLOGY GROUP LLP

What TUMOR INSTITUTE RADIATION ONCOLOGY GROUP LLP does

Tumor Institute Radiation Oncology Group LLP (TIROG) is a physician-owned radiation oncology medical practice operating under an LLP structure in Washington state. The group comprises 15 radiation oncologists delivering cancer treatment services across 5 radiation therapy centers in the greater Seattle area. The practice traces its lineage to the Tumor Institute, established in 1932 at Swedish Hospital in downtown Seattle as the first cancer and radiation center in the Pacific Northwest, and that historical brand remains a defining element of the entity.

TIROG's service portfolio spans radiation oncology as its core offering, with specialized treatments layered on top, including Cyberknife robotic stereotactic radiosurgery and other advanced modalities. Through extensive partnerships with multiple area hospitals, the practice has access to virtually every radiation therapy modality across its 5 centers, and patients are acquired primarily through hospital referrals and physician networks rather than direct-to-consumer marketing.

The business model is fee-for-service professional services revenue: treatment is delivered through the 5 centers, billing is processed via standard insurance verification, and pricing is not publicly disclosed. The group is physician-owned with no disclosed external investors, parent company, or private equity involvement, and it serves the greater Seattle metropolitan area as its single operating geography.

Direct peers

• 21st Century Oncology: Multi-site community radiation oncology provider with centers across the U.S., offering IMRT, IGRT, stereotactic radiosurgery and brachytherapy. Directly comparable in modality mix and community-hospital partnership model.
• ProCure Proton Therapy Center: Network of proton therapy and advanced radiation oncology centers offering highly specialized radiotherapy modalities. Comparable as a multi-site, modality-differentiated radiation oncology provider, though concentrated in proton therapy.
• Toledo Clinic Cancer Center: Independent, physician-led multi-modality cancer center offering radiation oncology, medical oncology and hematology services. Comparable as a physician-owned specialty oncology group operating community-based radiation therapy services.
• GenesisCare: One of the largest outpatient radiation oncology and cardiology networks globally, operating multi-site radiation therapy centers with broad modality coverage. Comparable as a multi-site radiation oncology provider serving community cancer patients with advanced modalities including stereotactic radiosurgery.

Broad incumbents

• US Oncology Network (McKesson): Large national network of community-based oncology practices including radiation oncology under McKesson. Overlaps with TIROG in physician-group radiation oncology service delivery, but operates at national scale across medical and radiation oncology.
• Sarah Cannon Radiation Oncology: The cancer services arm of HCA Healthcare, providing radiation oncology across multiple hospitals and freestanding centers. Comparable as a multi-site radiation oncology provider embedded in a broader oncology service line.

Others

• Varian Medical Systems (Siemens Healthineers): A leading manufacturer of radiation therapy equipment including linear accelerators and Cyberknife systems. Comparable as the underlying technology vendor whose equipment TIROG uses, rather than as a direct competitor in service delivery.
• Cyberknife provider networks (Accuray): Accuray is the manufacturer of the Cyberknife system TIROG operates. While not a direct competitor in patient services, Accuray's installed-base and clinical partnerships shape the competitive landscape of Cyberknife-equipped radiation oncology providers.
• ASTRO (American Society for Radiation Oncology): Professional society that defines practice standards and reimbursement advocacy for radiation oncology. Indirectly comparable as a peer in the radiation oncology ecosystem rather than a direct competitor; relevant to understanding competitive context.

Regional players
