Radiation Oncology Consultants

What Radiation Oncology Consultants does

Radiation Oncology Consultants (ROC) is a privately held physician practice group founded in 1966 and headquartered in the Chicagoland area of Illinois. The practice delivers comprehensive radiation oncology services across 10 hospital-based cancer care centers operated in partnership with Advocate Health (five sites), AMITA Health, AdventHealth, and Northwestern Medicine. ROC employs 18 board-certified radiation oncologists plus a supporting team that includes physician assistants and nurse practitioners, with practice leaders holding medical director roles at multiple partner hospitals.

ROC offers what it describes as a full portfolio of radiation modalities — external beam photon therapy, intracranial and extracranial stereotactic radiosurgery (CyberKnife, Gamma Knife, LINAC-based SRS), stereotactic body radiation therapy (SBRT), volumetric arc therapy (RapidArc on Varian TrueBeam), high-dose and low-dose brachytherapy (including permanent prostate seed implants, HDR for gynecologic and prostate cancers), accelerated partial breast irradiation (APBI), intraoperative radiation therapy (IORT), and radiopharmaceutical therapy such as Xofigo (radium-223). The practice participates in national cooperative group clinical trials through RTOG, GOG, COG, and PCG.

Commercially, ROC operates a traditional fee-for-service private practice model. Revenue is generated through insurance reimbursement for professional physician services — consultations, treatment planning, daily treatment delivery, and follow-up care — with the practice accepting most major commercial and government payers (Aetna, Blue Cross Blue Shield, Cigna, Humana, Medicare, Medicaid, United Healthcare). Patients access the practice primarily through physician referrals from urologists, medical oncologists, surgeons, and primary care physicians across Chicagoland, with a dedicated referral hotline and self-referral and second-opinion channels also offered. ROC bills its own physician professional charges separately from the hospital facility charges billed by its partner hospitals.

Scale indicators4 records

Expansion highlights4 records

Direct peers

• Vantage Oncology: Former community radiation oncology platform acquired by McKesson/US Oncology; closely comparable as a multi-site independent radiation oncology practice serving hospitals and freestanding centers before its consolidation.
• Tennessee Oncology: Large physician-owned oncology practice group operating multiple sites across Tennessee and beyond with comparable breadth across radiation and medical oncology; analogous private-practice model at scale.
• 21st Century Oncology (now part of GenesisCare): Was one of the largest community radiation oncology practice groups in the U.S. before its absorption into GenesisCare; ROC is comparable as an independent, multi-site radiation-oncology group delivering external beam, brachytherapy, and radiosurgery in a defined metro region.

Broad incumbents

• US Oncology Network (McKesson): McKesson-owned national network of community oncology practices (medical and radiation); comparable to ROC because it aggregates independent physician practices into a multi-state, multi-modality service platform serving hospital- and freestanding-based cancer care.
• GenesisCare: One of the largest global radiation oncology and cardiology operators with hundreds of centers; ROC is comparable as a multi-modality radiation oncology group delivering CyberKnife, Gamma Knife, SBRT, brachytherapy, and radiopharmaceuticals at scale, though at a meaningfully smaller footprint.

Regional players

• City of Hope (formerly Cancer Treatment Centers of America): Specialty oncology provider operating destination cancer centers including Chicago metro locations; comparable as a multi-modality cancer care brand competing for complex and self-referred patients in Chicagoland.
• Advocate Medical Group Radiation Oncology: Employed-physician radiation oncology group within the Advocate Health system that hosts ROC at five hospital cancer centers; a direct substitute for hospital-system-owned professional services.
• Northwestern Medicine Department of Radiation Oncology: Academic radiation oncology department at Northwestern operating a competing Gamma Knife center and proton beam facility within the same Chicagoland market as ROC, directly contesting complex intracranial and pediatric cases.
• University of Chicago Medicine Radiation Oncology: Academic radiation oncology program within the same Chicagoland geography, delivering SBRT, brachytherapy, and proton therapy; competes with ROC for tertiary referral cases and clinical trial enrollment.

Others

• Varian (Siemens Healthineers): Manufacturer of TrueBeam, RapidArc, and the broader Varian radiation oncology platform that ROC operates across its partner hospitals; included as an ecosystem enabler whose product roadmap shapes ROC's modality mix and capex requirements.
