Stereotactic Body Radiation Therapy (SBRT)
Stereotactic Body Radiation Therapy (SBRT) is a form of highly precise radiation therapy that targets tumors in the body with extreme accuracy. It is sometimes referred to as stereotactic ablative radiotherapy (SABR).
Stereotactic Body Radiation Therapy (SBRT) is a form of highly precise radiation therapy that targets tumors in the body with extreme accuracy. It is sometimes referred to as stereotactic ablative radiotherapy (SABR). SBRT combines advanced imaging techniques with focused radiation beams to treat tumors in the body, including the lungs, liver, pancreas, spine, and prostate, among other areas.
Key Features of SBRT:
- Precision Targeting: SBRT uses advanced imaging and computer planning to deliver radiation precisely to the tumor, minimizing exposure to surrounding healthy tissue.
- High-Dose Delivery: It delivers a high dose of radiation in a few treatments (typically between 1 to 5 sessions), which is much higher than the doses used in conventional radiation therapy.
- Real-Time Tracking: SBRT often incorporates real-time imaging and tracking techniques to monitor the tumor's position and make adjustments during treatment.
- Non-Invasive: SBRT is a non-invasive treatment that does not require surgical incisions.
Benefits of SBRT:
- Short Treatment Course: SBRT requires fewer treatment sessions compared to conventional radiation therapy, which can improve patient convenience and quality of life.
- Minimized Side Effects: The precision of SBRT reduces the impact on healthy tissues, potentially leading to fewer side effects.
- High Local Control Rates: SBRT offers high rates of tumor control due to the delivery of high radiation doses directly to the tumor.
- Outpatient Treatment: SBRT is often performed on an outpatient basis, allowing patients to return home the same day.
Applications of SBRT:
- SBRT can be used to treat various types of tumors, including:
- Lung cancer
- Liver tumors
- Pancreatic cancer
- Prostate cancer
- Spinal tumors
- Kidney cancer
- Certain types of brain tumors and other extracranial tumors
Treatment Planning and Delivery:
- Planning: Treatment planning involves using advanced imaging techniques such as CT, MRI, or PET scans to create a detailed treatment plan that maps the tumor's location, shape, and size.
- Delivery: During treatment, the patient is positioned precisely, and the radiation is delivered according to the treatment plan using specialized equipment. Real-time tracking is used to monitor the tumor's position and adjust the radiation delivery as needed.
Conclusion:
Stereotactic Body Radiation Therapy (SBRT) offers an effective and efficient treatment option for patients with certain types of tumors. Its precision targeting, short treatment times, and minimized side effects make it a valuable option for both patients and healthcare providers.
