Radiation treatment can target and shrink tumors as well as kill cancer
cells. The Radiation Oncology Department at Lake Charles Memorial Health
System is the top facility for cancer treatment in Southwest Louisiana,
comparable to facilities in large metropolitan areas.
Trilogy, our two linear accelerators, utilize advanced technology such as
Smart Arc and Align RT. Close to 3 in 5 of cancer patients will receive radiation therapy, intensity-modulated
linear accelerators utilize a radiation technology that more accurately
pinpoints and destroys cancer cells in less time and with less side effects.
We also utilize computerized real-time positioning during radiation treatment
sessions to manage the motion of cancerous tumors.
Intensity Modulated Radiation Therapy (IMRT)
Intensity Modulated Radiation Therapy (IMRT) gives radiation oncologists
the tools and technology necessary to pinpoint and destroy cancer cells
using non-invasive therapy. Imaging technology such as computed tomography
(CT) gives the oncologist a three-dimensional image of the growth. This
allows for precision in planning treatment of the cancer and eradication
of the tumors using radiation therapy. Our technology enables us to maximize
control of the radiation in order to precisely focus beams and protect
surrounding, healthy parts of the body.
Align RT uses the leading Surface Guided Radiation Therapy (SGRT). During
treatment, a patient's motion is tracked by AlignRT and detects tiny
differences in breathing to ensure radiation is stopped until the patient
is correctly positioned. The system can sense even tiny movements with
sub-millimeter accuracy. In particular for breat cancer, this technology
has been shown to help reduce radiation exposure to the heart while treating
left-breast cancer. The cancer is treated, and the heart is protected.
SmartArc technology is used for Volumetric Intensity Modulated Arc Therapy
(VMAT), which allows fast and precise radiation therapy. This advanced
form of treatment quickly rotates the linear accelerator around the patient
while the treatment beam is on and is designed to significantly reduce
treatment time compared with traditional methods, allow greater treatment
accuracy, and reduce radiation dose to healthy tissue. This provides treatment
plans that are comparable to standard IMRT plans but with a shorter treatment time.
Accelerated partial breast irradiation (APBI)
Accelerated Partial Breast Irradiation (APBI) is a breast radiation therapy
in which focused radiation is delivered specifically to the part of the
breast where the tumor was removed and in a shorter timeframe. APBI treatments
can be administered via brachytherapy or through external radiation beam
techniques. Requirements for APBI typically include a small tumor, clear
surgical margins after a lumpectomy and preferably no lymph nodes containing
cancer. Therefore, APBI may be a suitable treatment option for women with
early stage breast cancer.
For certain types of cancer - including gynecologic cancer, prostate cancer,
esophageal cancer, breast cancer, and lung cancer - is brachytherapy,
which essentially means "short distance therapy." This technologically
advanced and complex method can be accomplished in minutes, and utilizes
tiny sources of radioactivity seeds which are precisely placed internally
directly beside tumors using a high dose rate to destroy cancerous growths.
Deep Inspiration Breath Hold (DIBH)
Deep Inspiration Breath Hold (DIBH) is a radiation therapy technique where
patients take a deep breath during treatment, and hold this breath while
the radiation is delivered. By taking a deep breath in, your lungs fill
with air and your heart will move away from your chest. DIBH can be useful
in situations where radiation therapy is necessary in the chest region,
and it is desired to avoid radiation dose to the heart. DIBH involves
matching the delivery of radiation to the breath hold in order to limit
the amount of your heart exposed to the radiation beam during treatment.
