Treatment Options

 

At Banner Good Samaritan Medical Center, we offer a variety of radiation oncology treatment options:


Intensity Modulated Radiation Therapy (IMRT) uses highly advanced computer-generated planning to conform multiple radiation beams of differing intensities that are precisely shaped to the intended target volume. Because of the precision of these beams it is possible to deliver a higher dose to the target volume than with conventional radiation therapy, while significantly reducing doses delivered to healthy normal tissue.


Stereotactic Radiosurgery (SRS) is the delivery of a single high dose of radiation to a small, well-defined target within the head, while minimizing the radiation dose to the surrounding normal brain. It is a non-invasive procedure using the new Novalis TX linear accelerator to deliver converging beams of high energy X-rays by rotating the beams about the target. Newer machines are faster, allowing for shorter bursts of radiation. A CT scanner make sure the radiation is being delivered to the proper area and turns off the radiation if the patient moves or becomes stressed during the procedure; with this faster and more precise technology, patients may not have to be placed in a head fixation device. In addition, we have the ability to deliver Fractionated Stereotactic Radiation Therapy, which is similar to SRS with the exception that multiple treatments are given using a head frame that can be removed between treatments and reapplied with high levels of reproducibility.


TomotherapyTomoTherapy Hi-Art System® is an advanced radiation device used for the treatment of cancer. TomoTherapy provides physicians with 3-D imaging of a tumor. It delivers radiation from 360 degrees utilizing computerized tomography (CT scanning) with highly targeted radiation beams. This new system allows more accurate identification and treatment of cancerous tumors and reduces exposure of healthy tissue to radiation and treatment time for patients.

Banner Good Samaritan was the first medical center in the Phoenix area to offer Tomotherapy, an advanced radiation device that can deliver highly targeted radiation for more accurate identification and treatment of cancerous tumors while reducing exposure of healthy tissue to radiation.


Radioembolization provides the delivery of millions of microscopic radioactive glass beads directly into inoperable liver tumors through a tiny catheter steered into the artery that feeds the tumor. The beads become lodged within the tumor vessels, where they deliver the local radiation that causes tumor death.


Total Body Irradiation (TBI) is utilized for treating mycosis fungoides and cutaneous T-cell lymphomas. 


Brachytherapy involves placement of radioactive sources within the body to deliver local doses of radiation at High and Low Dose Rates. This may be done utilizing temporary placement of radioisotopes in intracavitary applicators such as gynecological applicators or the Mammosite® partial breast irradiation device, or in surgically implanted catheters, such as for lung, breast, head and neck, connective tissue, gastrointestinal malignancies and uterine disease. Brachytherapy also may be given with permanent implants of small radioactive seeds, used for prostate or brain tumors. All of these methods are highly effective at delivering a therapeutic dose to a small volume while sparing healthy tissue.


Hyperthermia, or elevated temperatures, can be used to enhance the effectiveness of radiation therapy.  It is frequently used to treat recurrent cancer in areas that have been previously treated.  Because of the prior radiation, additional radiation is very limited and may not be very effective.  The addition of hyperthermia improves the chances that retreatment will be successful. 

Hyperthermia is applied by the use of microwave applicators that can raise tissue temperatures to about 43 degrees Celsius (about 109 degrees Fahrenheit).  The heat only penetrates about oneinch deep so this therapy is normally only used for superficial cancers such as in the chest wall. 


SAVI Center of Excellence:  Banner Good Samaritan Medical Center is a center of excellence in accelerated breast partial irradiation for their use of the SAVI® applicator, an advanced therapy for breast cancer as part of breast conservation therapy. The SAVI applicator can provide important advantages for women with early-stage breast cancer.
