Our Cancer Care Technologies

Accelerated Partial Breast Irradiation (APBI)

Accelerated partial breast irradiation (APBI) is high-dose-rate (HDR) internal therapy for breast cancer, administered following a lumpectomy. There are several different applicators including SAVI®, Mammosite®, and Contura®. A radioactive Iridium-192 seed at the end of a metallic wire and contained within a computer-controlled HDR delivery system is directed to 50 or so pre-defined positions within a set of catheters, which are inserted into the lumpectomy site through plastic tubes or a balloon. The HDR delivery system directs the seed sequentially along each catheter tube, stopping at pre-defined dwell positions and delivering radiation along the length of the tube within the lumpectomy site and immediate surrounding area. Treatment is delivered twice a day over five treatment days. After each application, the radioactive seed is withdrawn from the tubes into a lead-lined box and the patient (now non-radioactive) can go home. After the ten treatments are completed, the balloon or catheter array is removed.

Brachytherapy

Brachytherapy, also known as internal radiation therapy, is a form of radiation therapy where a temporary or permanent radioactive implant is placed inside the patient. This makes it possible to place a higher dose of radiation near the tumor, while reducing radiation exposure to other parts of the body. The radiation is delivered either by needles inserted into the tissue, or by a special applicator placed into a body cavity near the tumor. Special applicators could include tubes, capsules, or balloon-like material. Depending on the type of cancer and treatment, the implants can be left in place anywhere from a few minutes to a few months.

CT Scanning & Simulation

Computer Tomography (CT) Scanning & Simulation allows the cancer specialists to design a treatment plan specifically for the patient based on the size, location, and shape of the tumor. The patient will have three-dimensional images (CT Scans) taken. These are used with the treatment planning software that helps determine how to best deliver the radiation beams while reducing damage to surrounding areas. In some cases, it may be necessary to mark the patient’s skin with a tiny marker so that the patient is perfectly realigned in the correct position for every session of radiation therapy. The need for a temporary or permanent marker will be discussed with the patient before the simulation.

Image-Guided Radiation Therapy (IGRT)

Image-Guided Radiation Therapy (IGRT) combines three-dimensional images, such as CT scans, with the precise technology of either 3-D or intensity-modulated radiation therapy (IMRT) to pinpoint and treat cancerous tumors. The images allow the cancer specialists to precisely localize the tumor each time radiation therapy is administered. This improves both accuracy of delivery and safety by reducing radiation exposure to other areas of the body including nearby tissue and organs. IGRT is used to treat tumors in areas of the body that are prone to movement, such as the lungs, liver, and prostate gland, as well as tumors located close to critical organs and tissues.

Intensity-Modulated Radiation Therapy (IMRT)

Intensity-modulated radiation therapy (IMRT) is an advanced form of external radiation treatment that allows precise targeting of tumor cells. The CT simulator localization scan or other three-dimensional images provide the radiation oncologist with an understanding of the shape and location of the tumor. With 3D planning, the radiation oncologist specifies the dose from various beams and sums up those doses to calculate the dose to tumor and normal tissue (forward planning). With IMRT, the radiation oncologist specifies the dose desired to give the tumor and the doses acceptable to the normal tissues (as low as possible). Then the computer system provides millions of alternative beam positions and the varying intensities of each beam, comparing one plan to the next until the best plan is identified. This is called inverse planning. Since each beam is broken up into many sub-beams of varying intensity the process is called intensity-modulated radiation.
