Radiation Therapy News and Research

RSS

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

Proton therapy shows excellent outcomes, minimal side effects in high-risk neuroblastoma patients

Researchers from Children's Hospital of Philadelphia 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, finding both that proton therapy was effective at reducing tumors and demonstrated minimal toxicity to surrounding organs.

New technology provides clearer picture to clinicians treating gynecological cancer

New technology developed at Western University is providing an improved way for radiation oncologists to deliver treatment to women with gynecological cancers, including vaginal, cervical and uterine cancer.

Cancer vaccine injected into tumour could kill all cancer cells

Researchers have developed an experimental cancer vaccine that when injected into a single tumour can help trigger the immune system to kill the cancer cells circulating within the body. The results of the study titled, “Systemic clinical tumor regressions and potentiation of PD1 blockade with in situ vaccination,” were published in the latest issue of the journal Nature Medicine, this week, Monday.

High-dose standard radiation treatment well-tolerated by patients with centrally located NSCLC

Stereotactic Body Radiotherapy, a high-dose, precisely delivered radiotherapy, is considered the standard treatment for patients with medically inoperable, node-negative, non-small cell lung cancer.

Magnetic nanoparticles can 'heat up' tumor cells

Unfortunately, cancer isn't simply a single disease, and some types, like pancreas, brain or liver tumors, are still difficult to treat with chemotherapy, radiation therapy or surgery, leading to low survival rates for patients.

New study highlights need for equity in access to radiation therapy care in rural areas

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.

UB researchers develop new method to more accurately predict tumor growth rates

University at Buffalo researchers have developed a new method to more accurately predict tumor growth rates, a crucial statistic used to schedule screenings and set dosing regimens in cancer treatment.

Research identifies genomic risk factor associated with stroke in childhood cancer survivors

Research at St. Jude Children's Research Hospital has identified a genomic risk factor associated with stroke in childhood cancer survivors. The findings were announced today at a press conference as part of the American Association for Cancer Research annual meeting in Atlanta.

$Breakthrough alpha-ray treatment of iodine-refractory thyroid cancer with multiple metastases$

Breakthrough alpha-ray treatment of iodine-refractory thyroid cancer with multiple metastases

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%.

Low-dose radiation therapy may increase uptake of therapeutic nanoparticles by brain tumors

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.

Selective destruction of prostate tumor as effective as complete prostate removal

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.

Cholesterol lowering drug can also help treat cancer-associated cachexia

Brazilian researchers have discovered that a drug regularly prescribed to control cholesterol can also be used to treat cachexia, or wasting syndrome, a condition characterized by rapid weight loss and muscle atrophy associated with extreme physical weakness.
