Radiation Oncology Program

St. Joseph Hospital Orange

Mon - Fri: 8 a.m. - 5 p.m.

The Radiation Oncology Program at The Center for Cancer Prevention and Treatment is an integral part of our comprehensive, multidisciplinary cancer program, providing advanced technology and innovative care. With two state-of-the-art Varian Linear Accelerators, including TrueBeam®, three board-certified radiation oncologists, dedicated on-site physicists, dosimetrists, therapists and nurses, the Radiation Oncology Program delivers nearly 14,000 radiation treatments per year to both adults and the pediatric population.

Our experienced radiation specialists offer the latest radiation techniques and technology necessary to target tumors while minimizing exposure to normal tissue.

Our Radiation Oncology specialists work together with a team of experts from many areas of medicine to develop a personalized treatment plan that meets each patient's unique medical and personal needs. Personalized treatment plans enhance the patient experience and contribute to improved clinical outcomes.

By combining sophisticated technology and the latest treatment options with a compassionate environment and experienced, caring staff, we care for the whole patient . . . body, mind and spirit.

The following radiation therapy modalities are offered:

  • Intensity Modulated Radiation Therapy (IMRT) using the Varian Trilogy with RapicArc capability.
  • Image-Guided Radiation Therapy (IGRT) using 3D imaging for precise localization to correct for subtle changes to tumor location during treatment with millimeter precision.
  • Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT) delivering high-dose precision radiation to small areas in one to five treatments. This is commonly used for brain, lung, bone and liver tumors.
  • Intraoperative Radiation Therapy (IORT) for early stage breast cancer delivering a single treatment at the time of surgery using electron beam therapy with Mobetron.
  • High dose rate (HDR) brachytherapy for breast and gynecologic malignancies.
  • Low dose rate (LDR) brachytherapy for prostate cancer using permanent I-125 seed implants.
