St. Joseph's Cancer Center offers treatments using advanced medical technology.
More than half of our current cancer patients are treated with radiation therapy in which
high-energy radiation is carefully used to pinpoint and destroy cancer cells in the body. The
Radiation Oncology Department, under the clinical leadership of Lesley Ann Hughes, MD, Section
Chief of Radiation Oncology, continues to develop more precise treatment strategies
including Intensity-Modulated Radiation Therapy (IMRT), Image-Guided Radiation
Therapy (IGRT) and High Dose Rate Afterloading (HDR) Brachytherapy.
Intensity-Modulated Radiation Therapy (IMRT)
Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision
radiotherapy, administered by an Elekta SynergyTM Linear Accelerator. It delivers precise
radiation doses to a malignant tumor or to specific areas within the tumor. The radiation
dose is designed to conform to the three-dimensional (3-D) shape of the tumor by focusing a higher
radiation dose while minimizing exposure to healthy tissue. IMRT can be used to treat cancers of
the prostate, head and neck, brain, breast, and lung, as well as gynecologic tumors, lymphomas and sarcomas.
Image-Guided Radiation Therapy (IGRT)
Image-guided radiation therapy (IGRT) assures that the radiation dose is targeted to the tumor.
Our Elekta SynergyTM combines both IMRT with state-of-the-art three-dimensional X-ray Volume Imaging (XVI) that
enables the radiation oncologist to adjust the radiation beam to target the tumor. This accuracy allows higher
doses of radiation to be delivered safely.
High Dose Rate Afterloading (HDR) Brachytherapy
The temporary implantation of radioactive sources directly into the cancerous site. This
outpatient procedure is effective in treating gynecologic, lung, breast and other cancers.
Another option for some women is Mammosite, a non-invasive therapy designed to deliver
the prescribed radiation dosage following a lumpectomy for breast cancer. The Mammosite
treatment is completed in five outpatient treatment days. It provides minimal radiation
exposure to healthy tissue and reduces the potential for side effects and cosmetic damage.
