The present-day collaboration of doctors, researchers, and technology has enabled the fast growth of delivery techniques for both internal and external radiation doses. Advances in radiation treatment allow doctors to accurately target tumors, even in difficult instances like lung cancer, where the organ is constantly in motion and close to delicate tissues like the heart.
This accuracy makes treating patients effectively without endangering the nearby healthy tissue possible. Radiation therapy has, therefore, become a widely accepted treatment modality with encouraging results, especially for instances that are challenging or incurable. In this blog, we will delve into some of the latest innovations in radiation therapy.
Volumetric Modulated Arc Therapy
One of the few facilities offering volumetric modulated arc treatment (VMAT) for leukemia in children who require whole-body irradiation before bone marrow transplantation is CHLA.
Patients are treated conventionally using a single radiation beam from a distance of around ten feet. However, this may give the lungs too many dosages, resulting in dangerous side effects such as pneumonitis.
Using intensity-modulated radiation treatment, VMAT provides various body areas with tailored radiation dosages. This makes it possible to give the lungs considerably smaller dosages. With VMAT, radiation dosages are also significantly more precise.
Spatially Fractionated Radiation Therapy
Although adults have had access to this therapy for decades, modern technology has significantly enhanced it. One of the first hospitals in the world to use it for pediatric patients is Children’s Hospital Los Angeles.
Spatially fractionated radiation treatment is specifically designed to treat patients with huge, bulky tumors by delivering high-dose radiation to specific, localized parts of the cancer rather than the entire mass. Research has demonstrated that this method can cause significant changes across the tumor with few negative effects.
4D Image Guidance
A tumor might be a moving target since the organs in the body move, such as while breathing. To combat this, medical professionals create radiation treatments that are administered in between breathing cycles by using 4D imaging technology to pinpoint the exact position of a tumor at any particular time. Intensity-modulated radiation treatment (IMRT) forms beams of varying strengths to match the tumors, and SBRT both employ this technique.
With the use of 4D imaging, researchers can make sure that radiation therapy precisely targets tumors while limiting exposure to internal organs such as the heart or lungs during the patient’s respiration cycle.
There is less chance of adverse consequences since physicians save more of the good tissue. They can completely ablate the tumor in cases of stage I lung cancer, obviating the need for surgery. They can fully avoid the heart when it comes to breast cancer.
Conclusion
Radiation treatment has a bright future, with further research and technology developments opening the door to more accessibility and efficacy. Proton therapy, immunotherapy combinations, and individualized treatment regimens based on each patient’s unique genetic profile are just a few innovations that will transform how cancer is treated.
Furthermore, artificial intelligence and machine learning improvements will improve therapy administration and planning, further maximizing results while reducing side effects. Radiation treatment is going to be more and more important in the battle against cancer as these advancements keep happening.
