7 Radiation Therapy Trends to Watch for at ASTRO 2022



According to Michael Dattoli, at ASTRO 2022, radiation therapy experts will discuss the most recent advancements in the field. Several emerging trends will be presented at the Society’s annual meeting, which will take place in November. These breakthroughs are expected to fundamentally alter the way cancer is treated by doctors. This article will examine seven of them in greater detail. In the hope that one of these will assist you in making a decision about which technologies to pursue for your own patient If this is the case, continue reading for some suggestions and inspiration.

Highly accurate CT images serve as the starting point for artificial intelligence-based contouring of organs at risk. These images also serve as the foundation for the planning of radiation therapy treatments. A medical physicist working in the Radiation Oncology Department of the Hospital del Mar in Barcelona, Spain, has identified the top three trends he intends to present at ASTRO 2022 as intensity modulated radiation therapy (IMRT), dual energy imaging, and molecular imaging.

The use of artificial intelligence to treat patients will be a hot topic at ASTRO 2022. On the show floor, attendees were treated to a demonstration of an innovative artificial intelligence-driven treatment planning system. This system combines multiple CT images with a treatment plan in order to provide a more accurate diagnosis. It also enables radiation oncologists to edit treatment plans by applying changes to them automatically based on the images they are viewing. For example, the system can automatically detect the location of organs that are at risk and adjust treatment plans as needed.

Michael Dattoli observed that, reflexion PET-targeting adaptive therapy is currently undergoing a phase I/II clinical trial with the FDA, and it has the potential to significantly accelerate the treatment of metastatic cancer. Aside from that, it makes use of software that can convert MRI datasets into simulated CT images. When compared to CT, MRI provides more detail of soft tissues than CT, making it the preferred imaging technique for diagnosing and understanding the extent of disease. So, what can we do to improve the effectiveness of our treatment options?

Radiosurgery with stereotactic accuracy is another cutting-edge technique. With this technique, a large dose is delivered to a small area in a very precise manner. It is used to treat tumors in the head and brain, and it delivers radiation from several different angles. The radiation is directed at the tumor, with nearby structures being spared to the greatest extent possible. Because of its precision, this procedure is referred to as “radiosurgery” and is frequently referred to as a robotic procedure.

The advancement of proton beam radiation technology is also having an impact on the field of cancer treatment and research. This treatment entails directing protons at the cancerous tissue. Because the radiation from these beams is only released from the physics department at a specific distance, it’s important to remember that proton beam radiation can only target tumors that are located at a greater distance from the nearby healthy tissues. It also has the additional benefit of minimizing the radiation’s effects on healthy tissues, making it an increasingly popular cancer treatment option.

Another emerging treatment option, IMRT, is gaining popularity in the field of cancer treatment. When using IMRT, total body irradiation is increased; however, the risk of secondary malignancies increases significantly, particularly in younger patients. Head and neck tumors are particularly problematic for this technology, which also increases the patient’s overall radiation exposure as a result of the procedure. It may, however, have some applications in these areas in the future. The increasing use of IMRT may benefit cancer patients who have tumors of the central nervous system, tumors of the head and neck, or tumors of critical structures in these areas.

Michael Dattoli pointed out that, a¬†sham-radiation procedure is another new treatment method. Instead of a medical expert making a diagnosis, a radiation oncologist examines a cancer patient in detail and then makes a treatment recommendation. They examine their medical history and test results in order to determine the precise location of the cancer that requires treatment. Known as a’sim’, a simulated treatment involves the patient lying still next to a machine while the simulation is taking place.

The Food and Drug Administration is currently evaluating a new cancer treatment called intensity-modulated WAR. Cancer of the pelvic bones and vertebral bodies has been used to treat patients with this type of cancer. Its primary endpoint is tolerability, with secondary objectives including quality of life, overall survival, and progression-free survival as secondary goals. As a consolidation treatment, it is currently being evaluated, and additional research is needed to determine the benefits and limitations of this new treatment option.
