One of the key advantages of SBRT is its ability to complete treatment in just a few sessions, often as few as one to five sessions, compared to conventional radiation therapy, which may require daily treatments over several weeks. This condensed treatment schedule not only reduces the burden on patients but also minimizes disruptions to their daily lives, allowing them to resume normal activities sooner.
Furthermore, SBRT is particularly well-suited for treating tumors in challenging locations, such as those near critical structures like the spinal cord, liver, or lungs. Its precise targeting capabilities enable oncologists to deliver high doses of radiation to these tumors while minimizing the risk of damage to nearby healthy tissues, thereby expanding the range of cancers that can be effectively treated with radiation therapy.
The effectiveness of SBRT has been demonstrated across various cancer types, including lung cancer, liver cancer, prostate cancer, and pancreatic cancer, among others. Numerous studies have shown high rates of local tumor control and excellent long-term outcomes for patients treated with SBRT, making it a valuable addition to the oncologist’s arsenal of treatment options.
Despite its effectiveness, SBRT may not be suitable for all patients or all types of tumors. Factors such as tumor size, location, and proximity to critical structures must be carefully considered when determining whether SBRT is the appropriate treatment approach. Additionally, like any form of radiation therapy, SBRT carries some risk of side effects, which may include fatigue, skin irritation, and, in rare cases, damage to nearby organs.
