Saint Clare’s offers the region’s most advanced radiation treatment and technology for various types of cancers. Our accomplished radiation oncologists utilize the following treatment protocols and therapy delivery technologies:
- RapidArc® Volumetric Arc Therapy
- Intensity-Modulated Radiation Therapy (IMRT)
- Image-Guided Radiation Therapy (IGRT)
- Low Dose & High Dose Rate (HDR) Brachytherapy (radioactive seeds)
- Mammosite Brachytherapy (HDR therapy for breast cancer)
RapidArc® Volumetric Arc Therapy
RapidArc® treatments are delivered using a medical linear accelerator outfitted with an on-board imaging system that generates images to guide patient placement and treatment delivery. During a RapidArc® treatment, delivery of the radiation treatment is shaped and reshaped as it is continuously delivered from virtually every angle in a 360-degree revolution around the patient.
Intensity-Modulated Radiation Therapy (IMRT)
Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that utilizes computer-controlled linear accelerators to deliver precise radiation doses to a malignant tumor or specific areas within the tumor. IMRT allows for the radiation dose to conform more precisely to the three-dimensional (3-D) shape of the tumor by modulating—or controlling—the intensity of the radiation beam in multiple small volumes. IMRT also allows higher radiation doses to be focused to regions within the tumor while minimizing the dose to surrounding normal critical structures.
Image-Guided Radiation Therapy (IGRT)
Image-guided radiation therapy (IGRT), which is one of the most cutting-edge innovations in fighting cancer combines imaging and treatment capabilities into a single treatment system. Because tumors can move, IGRT allows oncologists to see and track the tumor at the time of treatment, and to make very fine adjustments to patient position to greatly increase the precision and accuracy of radiation therapy treatment. Knowing exactly where the tumor is allows clinicians to irradiate only the tumor, sparing the surrounding healthy tissue. This enhanced accuracy results in higher radiation doses to the tumor, creating an increased likelihood of controlling or eliminating the cancer.
High Dose Rate (HDR) Brachytherapy
Radiation oncologists use brachytherapy to apply a radioactive source, sometimes referred to as a radioactive seed, directly to the tumor while sparing nearby healthy tissue and surrounding organs. The seed is usually inserted using catheters, needles or applicators inserted into a body or directly into the tumor during a simple outpatient procedure.
Mammosite Brachytherapy (HDR therapy for breast cancer)
The MammoSite® Radiation Therapy System, which received FDA clearance in 2002, is available at Saint Clare’s. MammoSite’s targeted radiation therapy works from the inside, meaning that a higher daily dose can be used for a shorter period of time, five days instead of the traditional radiation therapy course of five to seven weeks. Based on the HDR brachytherapy approach, MammoSite places the radiation source inside the space left when a breast tumor is removed. This delivers radiation to the area where cancer is most likely to recur. The treatment is provided daily over the course of five days, at intervals indicated by your oncologist.
