Princeton Radiation Oncology

What Princeton Radiation Oncology does

Princeton Radiation Oncology is a private, community-based radiation oncology practice founded in 1984 and headquartered in Monroe Township, New Jersey. The practice operates a flagship freestanding radiation oncology center plus seven satellite locations embedded within major hospital systems across New Jersey and Pennsylvania (Penn Medicine Princeton, CentraState, Saint Peter's University Hospital, Hunterdon, St. Mary, and Mercy Fitzgerald), giving it a regional footprint of up to eight sites following the January 2019 merger with Astera Cancer Care.

The clinical offering is built on a portfolio of advanced radiation therapy modalities — IMRT, SBRT, SRS, HDR and LDR brachytherapy, proton therapy (at the ProCure Proton Therapy Center in Somerset, the first proton facility in the NJ/NY metro area), SpaceOAR Hydrogel for prostate protection, prone and partial-breast irradiation, prostate seed implantation, Deep Inspiration Breath Hold, and low-dose radiation therapy for osteoarthritis — unified under a proprietary methodology branded "Princeton Precision." Clinical delivery is supported by 12 (and post-merger 35 across Astera) board-certified radiation oncologists trained at premier institutions (Harvard, Johns Hopkins, Memorial Sloan Kettering, MD Anderson, Penn, MGH), and the practice has held consecutive QOPI three-year certifications from ASCO (2013, 2016, 2019).

Revenue is generated through insurance-based billing for radiation treatment services delivered on-site, accepting most major commercial carriers plus Medicare; pricing varies by case complexity and modality (with proton and SRS/SBRT cases carrying higher ASPs). The go-to-market motion is sales-led, driven by physician referrals from medical oncologists, surgeons, urologists, pulmonologists, gynecologists, and PCPs, supplemented by a direct-to-patient website, telemedicine channel, and earned media. Ownership sits within the Astera Cancer Care parent structure following the 2019 merger, with no disclosed PE/VC involvement.

Brands

• Princeton Precision: A precision treatment methodology combining multiple techniques including highly precise treatment planning, unsurpassed targeting accuracy, treatment delivery from many different angles, highly conformal radiation delivery systems, and proton therapy for tumor targeting with reduced radiation exposure to surrounding tissue.

Products and services

• Deep Inspiration Breath Hold (DIBH) A specialized radiation therapy technique in which patients take a deep breath to a precise level and hold it while radiation is delivered, minimizing motion of tumors near organs that move with breathing such as breast, lung, liver, and pancreas. Intended for cancer patients requiring precise, motion-controlled radiation treatment.
• HDR and LDR Brachytherapy Cancer treatment by placing radioactive sources (seeds) in or near tumors, with high dose rate (HDR) sessions lasting 10-20 minutes and low dose rate (LDR) permanent implants used for various cancers including breast, gynecologic, gastrointestinal, and prostate. Indicated for patients with breast, gynecologic, gastrointestinal, prostate, and other cancers suitable for internal radiation.
• SpaceOAR Hydrogel FDA-approved semi-solid absorbable gel injected between the prostate and rectum to create a protective barrier that reduces radiation exposure to the rectum during prostate cancer treatment, minimizing side effects and protecting quality of life. Intended for men undergoing radiation therapy for prostate cancer.
• Intensity Modulated Radiation Therapy (IMRT) Non-invasive radiation therapy using high-precision targeting via computer-controlled multi-leaf collimators that shape hundreds of beams to maximize radiation to tumors while minimizing damage to healthy tissue. Indicated for prostate, lung, gastrointestinal, head and neck, breast, and brain cancers.
• Partial Breast Irradiation (APBI) Accelerated partial breast irradiation delivering focused radiation to the lumpectomy area via catheter-based brachytherapy with small radioactive seeds, typically completed with twice-daily treatments over one week. Intended for selected breast cancer patients after lumpectomy.
• Prone Breast Radiation Therapy Radiation therapy delivered with patient lying face-down, allowing the breast to fall away from the chest wall to reduce radiation exposure to the heart and lungs. Especially beneficial for women with large breasts undergoing breast radiation therapy.
• Prostate Seed Implantation Minimally invasive outpatient procedure placing radioactive seeds in the prostate gland to target cancer cells while preserving healthy tissue. Pioneered at the practice since 1997 using the Seattle group's transrectal ultrasound-guided technique. Indicated for prostate cancer patients seeking a minimally invasive treatment option.
• Proton Therapy Advanced radiation treatment using positively charged protons that can be controlled for depth penetration to focus the beam on tumors while reducing exposure to surrounding healthy tissue. Available at the ProCure Proton Therapy Center in Somerset, NJ. Indicated for cancer patients who benefit from reduced radiation exposure to healthy tissue.
• Skin Cancer Treatment Radiation therapy for early-stage non-melanoma skin cancers using HDR brachytherapy with small radioactive seeds placed on the skin surface or external electron beam radiation for larger cancers, offering excellent tumor control with minimal scarring. Indicated for patients with early-stage non-melanoma skin cancers.
• Stereotactic Body Radiation Therapy (SBRT) Highly specialized technique delivering high doses of radiation to tumors with extreme precision over 1-5 daily sessions, used primarily for early-stage lung cancer and tumors of the spine, liver, adrenal glands, and other organs, as an alternative to surgery. Indicated for patients with early-stage lung cancer or localized tumors in moving organs.
• Stereotactic Radiosurgery (SRS) Non-invasive method of delivering high-dose radiation to brain tumors in a single treatment session using Brainlab technology for enhanced targeting accuracy, treating inoperable brain cancers and post-surgical tumor beds. Indicated for patients with brain tumors and post-surgical tumor bed treatments.
• Osteoarthritis Low-Dose Radiation Therapy (LDRT) Non-invasive treatment option for painful osteoarthritis and benign conditions (including tendonitis, plantar fasciitis, and Dupuytren's contracture) using focused low-dose radiation to relieve pain and improve function, with minimal side effects and no hospitalization required. Indicated for patients with chronic joint and soft tissue conditions seeking non-invasive pain relief.
• Telemedicine Appointments Video-based remote appointments using the Doxy.me platform allowing patients to consult with Princeton Radiation Oncology physicians from home, accessible via smartphone, tablet, or computer. Indicated for patients seeking consultations or follow-ups without an in-person visit.
• Princeton Precision A comprehensive precision treatment approach combining multiple advanced techniques including highly precise treatment planning, image guidance, unsurpassed targeting accuracy, and highly conformal radiation delivery systems to maximize tumor targeting while minimizing exposure to healthy tissue. Indicated for cancer patients seeking precision radiation therapy tailored to their specific case.
