Variations in Medicaid Reimbursements for Radiation Therapies

A new study finds wide state-by-state variations in Medicaid reimbursements to physicians who treat cancer patients with radiation therapies. These differences could compound existing disparities in access to health care in rural communities; which tend to have higher Medicaid coverage rates than metropolitan areas. Previous studies The study is available for free access through April…

Proton Therapy Shows Excellent Outcomes, Minimal Side Effects

Researchers from Children’s Hospital of Philadelphia (CHOP) and the Perelman School of Medicine at the University of Pennsylvania analyzed the largest cohort to date of pediatric patients with high-risk neuroblastoma treated with proton radiation therapy (PRT), finding both that proton therapy was effective at reducing tumors and demonstrated minimal toxicity to surrounding organs. High-risk neuroblastoma…

Breast Tomosynthesis for Screening Mammography in Older Women

Digital breast tomosynthesis (DBT) performs better than two-dimensional digital mammography (DM) as screening mammography in women aged 65 years and older; researchers report. “Tomosynthesis leads to the detection of more invasive (rather than in situ) cancers and fewer node-positive cancers; compared to conventional digital 2D mammography, suggesting that with tomosynthesis we are finding clinically important…

Highlights Need for Equity in Access to Radiation Therapy

The newest study of America’s radiation oncology workforce finds that gender and race gaps have narrowed slightly, although persistent and growing geographic disparities point to a need for more equity in access to radiation therapy care. The survey; which drew responses from more than 1,100 physicians across the country; finds that fewer radiation oncologists are…

Triple-Gaussian Model Improves Proton Therapy Plans

A new treatment planning system (TPS) for proton therapy has been shown to accurately predict delivered dose by modelling the beam as a combination of three Gaussian distributions. Researchers in Japan tested the system using an ionization chamber and radiochromic film in a simple; commercially available phantom. The results demonstrate a reliable and convenient method…

Radiotherapy Shows Early Promise In Patients With Esophageal Cancer

The experimental oncolytic adenovirus telomelysin (OBP-301) in combination with radiotherapy was safe and showed early clinical efficacy in vulnerable patients with esophageal cancer, according to results from a phase I clinical trial presented at the AACR Annual Meeting 2019, March 29-April 3. “Most standard therapeutic strategies for esophageal cancer; such as surgery and chemoradiotherapy; therefore…

MRI Guided Radiation Therapy For Pancreatic Cancer

Researchers are launching a multi-institutional trial to test the effectiveness of precise, higher dose, MRI-guided radiation therapy to treat pancreatic cancer. Because “High-definition MRI and daily treatment plan adaptation allow us to deliver ablative radiation doses safely to [patients with pancreatic cancer] for the first time,” Parag Parikh, MD, director of gastrointestinal radiation oncology and MRI-guided…

Alpha Ray Treatment of Iodine Refractory Thyroid Cancer

For many years, radioactive iodine which emits beta rays has been used for treatment of thyroid cancer. Generally, 5-year survival rates may exceed 90%. However, some thyroid tumors become resistant to iodine treatment (“iodine-refractory”), and a breakthrough approach is need. Many research groups have attempted to determine new methods for treatment of iodine-refractory thyroid cancer;…

MRI Provides Useful Findings In Discordant Core Biopsy

An essential part of breast intervention is the process of assessing concordance between imaging findings and core biopsy results. When pathology results are consider benign discordant; current standard of care is surgical excision, even though many of these lesions will ultimately be found benign. A new study published in the April 2019 issue of the…

Low dose Radiation Therapy Increase Therapeutic Nanoparticles

A new study led by Massachusetts General Hospital (MGH) investigators finds that radiation therapy may increase the uptake of therapeutic nanoparticles by glioblastomas, raising the possibility of using both growth-factor-targeted and immune-system-based therapies against the deadly brain tumor. The team describes how pretreatment with low-dose radiation increased delivery to tumors of nanoparticles carrying small interfering…

Laser Targeted Removal Of Prostate Tumors And Removal Of Prostate

Researchers from The University of Texas Medical Branch at Galveston, led by prostate cancer treatment pioneer Dr. Eric Walser, have shown that selectively destroying cancerous prostate tissue is as effective as complete prostate removal or radiation therapy while preserving more sexual and urinary function than the other treatments. This study is currently available in Journal of…
