ASTRO’s Top Six Trends in Radiation Therapy

At this year’s American Society for Radiation Oncology’s annual meeting, the following radiation therapy technology trends were labeled as the most up-and-coming. 

Flash Therapy
Labeled a “revolutionary” way to treat cancer, flash therapy has been under the radar for the past few years. Rather than giving fractions of radiation to patients over days or weeks at a time, a full dose is delivered swiftly. Healthy tissues react differently to high doses of radiation as opposed to smaller doses over time; the tissues recover well, and cancer cells are rapidly destroyed. This therapy can potentially revolutionize radiation therapy, making patient treatment slots more available. 

Image-Guided Radiotherapy Systems
Magnetic Resonance Imaging (MRI) guided linear accelerators (linac) systems gained popularity through the past few years thanks to their ability to allow real-time imaging during radiation therapy. With this process, patients are more aligned with the therapy through changes in tissue movement, breathing, food intake, bowel gas, etc. Though the results are more accurate and safer, they take longer to perform, and are being reserved for certain types of cancers. 

Proton: A Mainstream Treatment
Becoming more widely available, this therapy is highly accurate and performs better than the best photon therapy systems. Randomized trials will soon compare proton therapy versus photon therapy in prostate, lung, and breast cancer. Proton therapy interacts with cell biology differently than photon beam therapy. Proton flash therapy also makes proton systems more economically viable, since many more patients can be treated at once. 

PSMA PET For Prostate Cancer
Prostate-Specific Membrane Antigen (PSMA) Positron Emission Tomography (PET) imaging for prostate cancer can monumentally improve the diagnosis and treatment of prostate cancer. In male patients with prostate cancer, the drug for PET nuclear imaging of PSMA-positive lesions was approved by the FDA. 

Synthetic CT from MRI Is Cost-Effective for Radiotherapy
New software can convert MRI databases into synthetic CT image datasets to assist in treatment plans. Since separate CT scans are not needed, costs can be reduced and care can be sped up. MRI is preferred for diagnosis compared to CT, as it can help provide a better understanding of the disease extent. 

AI (Artificial Intelligence) in Radiotherapy
AI is being used mainly as a time saver, as it speeds up routine tasks, automates treatment plans, offers alternative options, and more. AI can target tumors, identify tissues to avoid using radiation on, and provide information to suggest better treatment decisions.

Novel ‘Cure’ For Cancer Treatment

A new report published in Nature titled “Decade-long leukemia remissions with persistence of CD4+ CAR T cells” highlights a novel treatment called CAR T, which is being hailed as a “cure” for cancer by Dr. Carl June, the principal investigator for the trial at the University of Pennsylvania.

June said, “Now we can finally say the word ‘cure’ with CAR T cells.” In 2010, when the trial began, the idea for this sort of therapy “was way out there,” he added.

June and his colleagues reported that the CAR T therapy wiped out cancer in two out of the three initial early-trial patients, all of who had chronic lymphocytic leukemia. Though the cancer disappeared, the CAR T cells stayed circulating through patients’ bloodstreams, almost guarding the body against future attacks.

In CAR T therapy, T cells (white blood cells that fight viruses) are removed from a patient’s blood and re-introduced after being genetically engineered to fight cancer. Patients’ T cells are taught to recognize and destroy B cells, a key player in cancer formation throughout the body. Without B cells – or cancer – patients require regularly-scheduled infusions of immunoglobulin infusions, which replenish antibodies.

Many people with blood cancer have benefitted from CAR T therapy, which has proved especially effective against acute leukemia. Roughly a third of patients who underwent the CAR T therapy have gone into remission, but many patients later relapse.

Dr. John F. DiPersio, chief of the division of oncology at Washington University in St. Louis, said, “The question is not only why some patients relapse or are resistant to therapy but why are some patients cured?”

He continued, “Oncologists don’t use words like ‘cure’ lightly or easily or, frankly, very often,” he said. “I guarantee that it’s not being used lightly. The patients we treated had far advanced disease,” he noted, adding, “the biggest disappointment is that it doesn’t work all the time.”

Using Medical Radiation Detectors

By 2030, the global medical radiation detection market is projected to reach $2,558.1 million; in 2020, the market was valued at $1,173 million, according to a new report from Researchandmarkets.com.

A variety of fatal illnesses can result when people are exposed to radiation for an extended period. Radiation detectors are medical equipment solutions that can detect the presence of radiation. Handheld Survey Meter (HSM), Personal Radiation Detector (PRD), Radiation Portal Monitor (RPM), and Radiation Isotope Identification Device are some of the options available to detect radioactive materials and ionizing radiation.

Dosimeters, radiation-detecting equipment, can detect Gamma rays, which are the most dangerous. Cancer rates have been rising, accelerating the need for medical radiation detecting equipment. An increase in diagnostic imaging facilities requiring medical radiation detectors has helped avoid unnecessary exposure.

Encouraging awareness in radiation-prone settings has been crucial when it comes to safety. In the upcoming years, the increased potential for medical radiation detection is expected to expand in emerging markets.

There are different branches of the global medical radiation detection market, including detection type, product, end-user, and region. Each category contains its sub-categories as well. All of these segments are what drive market growth.

Novel AI Might Predict Heart Attacks

New research published in the Journal of Nuclear Medicine shows how physicians can use Artificial Intelligence (AI) to predict heart attacks. The study included 293 participants with coronary artery disease; 22 people experienced a myocardial event during the 53-month follow-up period.

When used in combination with F-sodium fluoride (F-NaF) and quantitative coronary plaque analysis (via CT angiography) along with clinical findings, physicians can easily predict the risk of myocardial infractions.

Predicting heart attacks has been challenging in everyday clinical practice and is typically based on cardiovascular risk factors. Patients with coronary artery disease can have underlying conditions despite high scores.

Pitor J. Slomka, Ph.D., FACC, FASNC, FCCPM, director of Innovation in Imaging at Cedars-Sinai Medical Center in Los Angeles, said, “Recently, advanced imaging techniques have demonstrated considerable promise in determining which coronary artery disease patients are most at risk for a heart attack. These techniques include 18F-sodium fluoride (18F-NaF) PET, which assesses disease activity in the coronary arteries, and CT angiography, which provides a quantitative plaque analysis. Our goal in the study was to investigate whether the information provided by 18F-NaF PET and CT angiography is complementary and could improve prediction of heart attacks with the use of artificial intelligence techniques.”

The AI-assisted process exhibited a significant advancement in predicting heart attacks rather than employing clinical data alone.

Slomka said, “F-NaF PET combined with anatomical imaging provided by CT angiography has the potential to enable precision medicine by guiding the use of advanced therapeutic interventions. Our study supports the use of artificial intelligence methods for integrating multimodality imaging and clinical data for robust prediction of heart attacks.”

Henry Ford Health System Implants Novel Therapy for Brain Tumors

Surgeons at Michigan’s Henry Ford Health System successfully treated a patient who suffers from a recurrent brain tumor by delivering a dose of radiation therapy directly on the tumor. This new approach could revolutionize treatment by delaying or preventing future tumor cells from regrowing. Called GammaTile Therapy, the surgically targeted radiation therapy was the first of its kind performed in Michigan; the patient was a 41-year-old male.

Adam Robin, M.D., a neurosurgeon at the Hermelin Brain Tumor Center at Henry Ford, said, “The current standard of care for brain tumors is tumor resection, often followed by radiation, chemotherapy, or a combination of both. Approximately half of patients treated for brain tumors experience tumor recurrence within a year. In his most recent surgery, the patient was treated with a form of surgically targeted radiation therapy, which targets residual tumor cells with radiation before they can significantly replicate. Our hope is this therapy will delay or prevent the tumor cells from replicating and forming a recurrent tumor.”

GammaTile Therapy is cleared by the FDA and designed to delay tumor regrowth while protecting healthy brain tissue in patients who suffer from recurring tumors.

Mira M. Shah, M.D., a radiation oncologist at Henry Ford, external beam radiation therapy is usually delivered no sooner than two- to three weeks after surgery to let the incision heal. With GammaTile, the radiation is focused on specific areas of the brain using a type of brachytherapy (internal radiation) which delivers a therapeutic dose to the tumor during surgery.

Leaving the healthy tissue unharmed, GammaTile maximizes the amount of radiation aimed at the tumor and is critical for those patients who have received external beam radiation therapy, which exposes healthy tissue to radiation.

A bioresorbable, conformable 3D-collaten tile uses uniformly spaced radiation sources to target the tumor cavity after the tumor is removed. In just 33 days, 90 percent of the radiation dose is delivered, and after 100 days, the GammaTiles are considered free from radiation. The placement of GammaTile takes approximately five minutes.

Augmented Reality (AR) Becoming an Aspect of Surgery

ClariffEye, an industry-first solution that combines 2D and 3D visualizations, uses a 3D Augmented Reality (AR) system to enable surgeons to define and navigate through real-time. Royal Phillips announced the first patients had been successfully treated using ClariffEye at Sant Joan de Deu Barcelona Children’s Hospital in Spain along with the Armed Forces Hospital, Oman.

Philips integrated Spine Suite was used by both surgeons, which showcases the Azurion Hybrid Operating Room (OR) in conjunction with ClariffEye. Both surgeries performed with ClariffEye were spinal.

“The level of success of this surgery would not have been possible to reach without ClarifEye,” said Dr. Alejandro Peiró, Orthopedic surgeon and pediatric traumatologist at Sant Joan de Déu Barcelona Children’s Hospital.

Dr. Ahmed Al Jahwari, Head of Department Orthopedics and Spine Surgery at Hospital MoD, Oman, said, “Philips’ new technology enables us to perform less invasive procedures and produce better outcomes for patients with spine conditions. Thanks to the high quality of the intraoperative cone beam CT imaging and the positioning flexibility of the ClarifEye system, we can ensure that implants are in place which lowers post-operative CT scans to check implant placements.”

Spinal procedures can be challenging and fragile to maneuver for surgeons. Delicate neurological and vascular structures near the spine are susceptible to damage. Minimally-invasive techniques have become more prevalent thanks to recent technology, which reduces blood loss, soft tissue damage, and post-operative discomfort.

With ClariffEye, surgeons can utilize real-time imaging in addition to 3D navigation to increase accuracy and improve outcomes.

According to Science Reports, ClariffEye performed accurately better compared to open surgery without 3D navigation. Additionally, ClariffEye has a 98 percent accurate ability to place a pedicle screw during minimally invasive procedures.

“We’re excited that international access to ClarifEye is expanding, and more hospitals and patients will get to experience its benefits firsthand,” said Karim Boussebaa, General Manager Image Guided Therapy Systems at Philips. “As the latest addition to Spine Suite, ClarifEye adds a new dimension in surgical precision for patients. It is a great example of how we’re innovating procedures and helping clinicians to deliver on the Quadruple Aim of better health outcomes, improve patient experience and staff satisfaction, and lower cost of care.”

Fewer Imaging Exams Scheduled During Virtual Visits

New research published in the JAMA Network Open suggests primary care visits that take place via video or phone result in fewer imaging scan orders.

The COVID-19 pandemic has fueled telehealth as a primary way for physicians to offer patient care. As patients stay home to limit exposure to the virus, physician follow-up care can look different.

Using pre-pandemic data from more than 1.1 million patients, Kaiser Permanente researchers found that primary care doctors ordered imaging in roughly 59 percent of office visits versus 29 percent of virtual and 27 percent over the phone.

The study did not specify the reason behind the variance; however, the authors suggested patients who were more ill might have sought out in-person primary care.

Mary Reed, DrPH, a Kaiser Permanente research scientist, said, “It is possible that these differences in treatment might be driven by the types or seriousness of concerns that patients chose for each visit type, or by the degree to which physicians could assess the patient in each visit type. We need to explore these details further in future research.”

The study analyzed primary care appointments at Kaiser Permanente in Northern California between 2016 and midway through 2018; almost 2.2 million were evaluated. Video and telephone visits resulted in a lower number of medications prescribed (39 percent and 35 percent, respectively) compared to office-based visits, which were at 52 percent.

Overall, 25 percent of video visits required a follow-up appointment within a week. Telephone and in-person visits required follow-ups at 26 percent and 24.5 percent, respectively.

Emergency department visits or hospitalizations did not see a difference.

The study wrote, “In contrast to prior studies of direct-to-consumer telemedicine, we did not find evidence of over-ordering or over-prescribing among patients using telemedicine to visit their own primary care doctors. Video or telephone visits may be a convenient and safe way for patients to address some primary care needs without generating a substantial number of follow-up office visits or experiencing health events.”
