Radiation Oncology

Our radiation oncology service takes a team approach, involving board-certified radiation oncologists, physicists, dosimetrists, radiation therapists, nurses, dieticians, and other professionals in the evaluation, planning, delivery, and ongoing review of each patient’s treatment. Weekly multidisciplinary tumor boards/case conferences also enhance patient care.

Radiation may be used as a stand-alone treatment or in combination with surgery, chemotherapy, or biological therapy. Our radiation service is equipped with two linear accelerators, a CT simulator, and HDR (High Dose Rate) brachytherapy device. The data from the CT simulator is used to plan daily treatments.

Our advanced use of technology enables us to provide the latest radiation oncology treatments to our patients, such as:

  • Conventional Radiation Therapy, which is standard treatment for many malignancies. It can also be used for treating benign conditions such as pituitary tumors, meningiomas, and prophylaxis for heterotopic bone formation after hip replacements
  • 3D Conformal Radiation Therapy contours the radiation beam to the irregular shape and size of an individual’s tumor
  • Intensity Modulated Radiation Therapy (IMRT) uses computer-generated images to plan and then deliver even more tightly focused radiation beams to cancerous tumors than is possible with conventional therapy and maximizes the radiation dose delivered to the tumor while minimizing the radiation dose delivered to the surrounding normal tissues
  • Image Guided Radiation Therapy (IGRT) is a process of using various imaging technologies such as kv imaging, ultrasound, and CT scans to locate a tumor prior to each daily treatment. Radiation oncologists use image-guided radiation therapy to verify delivery of radiation to the cancer because tumors can move between treatments due to differences in the position of organs during the process of breathing
  • Stereotactic Radiotherapy is a non-invasive procedure that delivers a single very high dose of radiation using multiple beams focused on a tumor in the brain while sparing adjacent normal tissues. This enables us treat the same type of tumors that previously required referral to Gamma Knife Centers in New York and New Haven
  • Brachytherapy is a radiation treatment technique that delivers radiation to tumors by accurately placing radioactive sources, either permanently or temporarily, under careful guidance in close proximity to the tumor or within the tumor itself. This can be done as an inpatient with low dose rate techniques or using the newer high dose rate (HDR) brachytherapy equipment as an outpatient.  It is used primarily for treatment of prostate, gynecologic, and breast malignancies. For prostate cancers, we offer both Iodine and Palladium implants that permit convenient one-day treatment with excellent cure rates and a low rate of long-term side effects as an alternative to prostatectomy or external beam radiotherapy
  • Radiopharmaceuticals such as Quadramet (samarium) can be given intravenously for treatment of painful bone metastases and is especially useful for prostate cancer that has spread
