Unraveling Stereotactic Body Radiotherapy (SBRT): Precision in Cancer Treatment
Stereotactic Body Radiotherapy (SBRT) is a cutting-edge cancer treatment that delivers highly precise, high-dose radiation to tumors in fewer sessions compared to traditional radiation therapy. At ID Cancer Center, we are proud to offer SBRT as part of our advanced cancer treatment portfolio. This blog post will explore what SBRT is, how it works, its benefits, and what patients can expect during their treatment journey.
What is SBRT?
Stereotactic Body Radiotherapy (SBRT) is a non-invasive radiation therapy that uses advanced imaging and precision techniques to target tumors with sub-millimeter accuracy. Unlike conventional radiation therapy, which is typically administered over several weeks, SBRT delivers high doses of radiation in a smaller number of sessions, often between one to five treatments.
How Does SBRT Work?
SBRT works by focusing high-dose radiation beams on the tumor from different angles, ensuring that the maximum dose is concentrated on the tumor while sparing surrounding healthy tissues. Here's how the process typically unfolds:
Advanced Imaging: Detailed imaging scans, such as CT, MRI, or PET, are used to map the exact size, shape, and location of the tumor. This imaging ensures precise targeting during treatment.
Treatment Planning: The radiation oncologist, along with a team of medical physicists, creates a customized treatment plan. This plan takes into account the tumor's characteristics and the patient's anatomy to maximize treatment efficacy and minimize side effects.
Immobilization: To ensure accuracy, patients are positioned on a treatment table with the aid of immobilization devices. These devices help keep the patient still during each session, ensuring the radiation is delivered exactly as planned.
Radiation Delivery: The treatment itself involves delivering radiation from multiple angles around the patient. Advanced technologies, such as linear accelerators equipped with image guidance, ensure that the radiation beams are precisely focused on the tumor.
Benefits of SBRT
SBRT offers several significant advantages over traditional radiation therapy:
Precision: The high level of accuracy in targeting the tumor minimizes radiation exposure to surrounding healthy tissues.
Efficacy: High-dose radiation delivered in fewer sessions can be more effective in controlling and potentially eradicating tumors.
Convenience: With fewer treatment sessions required, SBRT offers greater convenience for patients compared to conventional radiation therapy.
Versatility: SBRT is suitable for treating various types of cancer, including lung, liver, pancreas, prostate, and spinal tumors, as well as metastatic cancers.
What to Expect During SBRT
Consultation: The journey begins with an initial consultation with a radiation oncologist who specializes in SBRT. During this visit, the doctor will review the patient's medical history, discuss treatment options, and outline the SBRT process.
Simulation: A simulation session is conducted to determine the optimal patient positioning and create a customized treatment plan. This session may involve additional imaging scans and the use of immobilization devices.
Treatment Sessions: SBRT is typically delivered in one to five sessions, with each session lasting between 30 to 60 minutes. During each session, the patient is positioned on the treatment table, and the radiation beams are precisely directed at the tumor.
Follow-Up: After completing SBRT, patients will have follow-up appointments to monitor their progress and manage any side effects. Regular imaging scans may be conducted to assess the treatment's effectiveness.
Advances in SBRT
The field of SBRT continues to evolve, with ongoing research and technological advancements enhancing its precision and efficacy. Innovations such as real-time tumor tracking, adaptive radiotherapy, and integration with other treatment modalities (like immunotherapy) are expanding the potential of SBRT in cancer care.
