American Association of Physicists in Medicine Issues Position on Medical Imaging Radiation Limits

When a medical imaging exam provides a clinical benefit, the only risk that should be considered is the exam itself rather than a patient’s previous radiation exposure, according to a statement from the American Association of Physicists in Medicine, the American College of Radiology and the Health Physics Society, citing potential adverse effects on patient care.

MD Anderson Research Highlights for June 30, 2021

The University of Texas MD Anderson Cancer Center’s Research Highlights provides a glimpse into recently published studies in basic, translational and clinical cancer research from MD Anderson experts. Current advances include expanded use of a targeted therapy for a new group of patients with leukemia, molecular studies yielding novel cancer therapeutic targets, insights into radiation therapy resistance and a community intervention to reduce cervical cancer rates.

Experimental Drug Makes Radiation Therapy More Effective, Less Damaging

DALLAS – May 20, 2021 – An experimental drug that has shown promise in protecting healthy tissue from collateral damage caused by radiation therapy for cancer also appears to enhance radiation’s capacity to kill tumors, a new study led by UT Southwestern scientists shows. The findings, published online in Science Translational Medicine, could provide a much-needed boost to the radiation treatments used against a variety of tumor types.

Improving the Precision of Treatment for Cancer Patients Receiving Radiation

Valley-Mount Sinai Comprehensive Cancer Care — part of Ridgewood, NJ, based Valley Health System — is now using new technology to improve the precision of radiation therapy by accounting for the continual motion of a patient’s anatomy so treatment is delivered with greater accuracy and effectiveness.

Valley is the only hospital on the east coast and, only fourth in the nation, using the latest generation of capabilities available in the newest iteration of ExacTrac Dynamic from Brainlab.

Exercise May Improve Effects of Radiation Therapy in Prostate Cancer

Cancer is the second leading cause of death around the world after heart disease. This week, researchers exploring the effects of exercise as a natural preventive tool and noninvasive treatment for cancer will present their work at the American Physiological Society (APS) Integrative Physiology of Exercise conference.

5G Wireless May Lead to Inaccurate Weather Forecasts

Upcoming 5G wireless networks that will provide faster cell phone service may lead to inaccurate weather forecasts, according to a Rutgers study on a controversial issue that has created anxiety among meteorologists.

Deep Look at Immune Cells in Patients’ Tumors Reveals Insights on Timing for Treatment Combinations

It’s clear that radiation therapy, or radiotherapy, an approach used to treat cancer since the early 20th century, can be an effective companion to newer, immune-stimulating approaches known as immunotherapy. Research from a team from Roswell Park Comprehensive Cancer Center explains how radiation helps boost the immune system’s ability to fight cancer in combination with immune checkpoint inhibitors — and provides new evidence that the timing of these therapies can make a big difference in how effectively they work together.

Jefferson Lab ES&H Deputy Director Receives Health Physics Society Honor

Bob May’s career-long aspiration has been to keep people from all walks of life and in different work environments safe from radiation in the workplace. Now, the deputy director of Environment, Safety and Health at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility has been honored for his dedication to the field by being named a fellow of the Health Physics Society.

Sylvester Comprehensive Cancer Center Urologist Leads Collaborative Study on Fertility Counseling Prior to Chemotherapy

For younger cancer patients, fertility counseling at the time of cancer diagnosis is important for making family planning decisions. Ranjith Ramasamy, M.D., a clinician and researcher at Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine, was the lead author of a new collaborative study, “Evaluation of Reported Fertility Preservation Counseling Before Chemotherapy Using the Quality Oncology Practice Initiative Survey,” published JAMA Network Open.

Jean Paul Allain: Then and Now

Jean Paul Allain is a professor and department head of the Ken and Mary Alice Lindquist Department of Nuclear Engineering, the director of the Radiation Surface Science and Engineering Laboratory, professor in Biomedical Engineering by courtesy and the Lloyd & Dorothy Foehr Huck Chair in Plasma Medicine at Penn State University.

Long-term study finds faster breast cancer radiation treatment as effective as longer course

Approximately half of the patients were randomly assigned whole breast radiation, delivered once per day over three to five weeks. The other half received external beam APBI, considered to be the least invasive approach to partial breast irradiation, which was given twice a day over five to eight days.
The study was long-term, with a median followup of 8.6 years.

Story Tips from the Department of Energy’s Oak Ridge National Laboratory, December 2019

An additively manufactured polymer layer applied to specialized plastic proved effective to protect aircraft from lightning strikes in lab test; injecting shattered argon pellets into a super-hot plasma, when needed, could protect a fusion reactor’s interior wall from runaway electrons; ORNL will celebrate the life and legacy of Dr. Liane Russell on December 20.

Yale Cancer Center researchers show adding radiation after immunotherapy improves survival time for patients with advanced lung cancer

The results of a phase II clinical trial by Yale Cancer Center (YCC) researchers show adding high-dose radiation after immunotherapy stops working increases survival time for patients with metastatic non-small-cell lung cancer (NSCLC).
