BENEFITS OF SABR
SABR (Stereotactic Ablative Body Radiation, also known as Stereotactic Body Radiation Therapy – SBRT) is a treatment technique that uses precisely targeted, very high dose x-ray beams to destroy small cancers. First developed in the early 2000s as an alternative to surgery for treatment of small lung cancers, it has since been proven to be highly eﬀective and safe in the treatment of a wide variety of cancer types throughout the body, including prostate cancer.
How long has SABR been used for prostate cancer?
SABR has been used to treat prostate cancer since 2003. Since this time the technique has been continually reﬁned since this time based upon published data of both safety and eﬃcacy.
How eﬀective is prostate SABR?
Published data from multiple centers throughout the world have demonstrated SABR to be at least as eﬀective as conventional 45-day treatment. For more detailed review of the data supporting prostate SABR, please see References .
Is prostate SABR safe?
Yes. There is a substantial body of peer-reviewed data demonstrating that the safety of prostate SABR is at least equivalent, if not superior, to that of conventional radiation therapy.For more detailed review of the data supporting prostate SABR, please see References .
Why isn’t prostate SABR available at more radiation centers?
Safe and eﬀective delivery of prostate SABR requires state-of-the-art linear accelerator technology, intensive medical physics support, and specialized physician expertise. Few community-based centers at present have this combination of attributes.
Is it feasible to be treated with SABR if I live outside of central Florida?
Yes. Special arrangements to facilitate the consultation, treatment planning, and treatment delivery process to meet out-of-town patients’ needs can be made as needed.
SABR differs from conventional radiation therapy for prostate cancer (also known as IMRT) in several significant ways.
- 1) Duration Treatment takes only 5 sessions instead of up to 45 sessions.
- 2) Margins The prescription dose of radiation is distributed more tightly around the prostate gland
- 3) Setup Patients are positioned in a more intricate manner
- 4) Preparation Patients have a more rigorous bowel and bladder preparation prior to each session
Dr. Brabham will review and discuss your case with you and determine whether SABR is an appropriate treatment option for your prostate cancer.
If appropriate and not already performed, Dr. Brabham will order imaging studies to determine the clinical stage of your prostate cancer.
PLACEMENT OF FIDUCIAL MARKERS
Three, small plastic markers called ﬁducials will be placed in the patient’s prostate in a procedure which is similar to a prostate biopsy, but quicker and typically much less uncomfortable. These markers will be imaged during each treatment to ensure precise positioning of the prostate to allow for on-target dose delivery.
TREATMENT PLANNING CT SCAN
During this session, the patient’s custom body mold will be created and a CT scan of the patient in this device will be performed immediately thereafter. Patients prepare for the scan with a self-administered enema to achieve an empty rectum and by drinking a moderate amount of water prior to the procedure to achieve a full bladder.
MRI of the prostate will be performed shortly after the CT simulation to generate the highest resolution images possible of the prostate and the surrounding anatomy. The MRI images will then be combined with the images from CT simulation, allowing Dr. Brabham to produce a highly accurate three-dimensional model of the patient’s anatomy to be used in treatment planning.
Treatment delivery typically occurs within one to two weeks of the treatment planning scans. Each treatment takes approximately 10 minutes of set-up time and approximately 2 minutes of radiation delivery time. Treatment is non-invasive and entirely painless. Patients perform the same bladder and rectal preparation as for the treatment planning scan.
FOLLOW-UP AFTER TREATMENT
After treatment you will follow up periodically in this clinic for PSA monitoring and overall clinical assessment.
“This entire oﬃce starting with the staﬀ up front are the most caring, competent caregivers I have ever encountered. The Dr. is so intelligent and clearly explains every step of the treatment. His nurse Mary is so caring and extremely knowledgeable in the care of the patient. Also all the staﬀ in the actual radiation treatment room make sure you are comfortable & everything is monitored so that treatment is performed correctly & with little to no discomfort. Excellent all around.”
