Through its introduction of state-of-the-art technology to treat cancer patients with radiation therapy, Staten Island University Hospital has earned an important reputation as a major cancer center treating patients with the most difficult-to-treat disease from across the nation and throughout the world.

At the heart of its Department of Radiation Oncology is innovative treatment using pinpoint precision radiosurgery, as well as IMRT. This technology allows high dose, sophisticated radiation to be delivered precisely to tumors while minimizing effects on normal healthy tissues.

Our Radiation Oncology department is, in fact, New York City's second largest facility.

Our linear accelerators, equipped with a special device called a multileaf collimator that shapes the radiation beam, delivers radiation in accordance with the treatment plan. The equipment can be rotated around the patient to send radiation beams from the most favorable angles for giving the tumor a high dose while preserving important healthy tissues. The linear accelerator provides an open-treatment environment in which patients are not enclosed.

Equipped with Intensity Modulated Radiation Therapy (IMRT), radiosurgery at Staten Island University Hospital uses computer-generated images to plan and then deliver even more tightly focused radiation beams to cancerous tumors than is possible with conventional radiotherapy. IMRT enables doctors to deliver substantially more cancer-killing energy to tumors while decreasing potentially harmful doses to surrounding healthy tissue. It optimizes a treatment plan based on a physician's dose instructions, and information about tumor size, shape and location in the body. IMRT is being used to treat tumors in the brain, breast, head and neck, liver, lung, nasopharynx, pancreas, prostate, and uterus. Based on nationally-gathered data, twice a day radiation is superior for head and neck, and some lung cancers.

University Hospital combines IMRT with Respiratory Gating technology so doctors can collect and use respiration motion data. Our radiosurgery experience has shown that in some cases, very small renal cell cancers might be treated with radiosurgery alone. Treatment is investigational.
