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.

Research identifies biomarkers in blood to fine-tune breast cancer interventions

Doctors may be able to spare patients unnecessarily aggressive breast cancer treatments by collecting and testing cancer cells in patients' blood, research from the University of Michigan and the University of Kansas suggests.

Breakthrough combo therapy lowers death risk in recurrent prostate cancer

Men whose prostate cancer returns after surgery or radiation therapy may now benefit from a new drug combination shown in clinical trials to cut the risk of death by more than 40%.

New approach protects the brain from radiation-induced cognitive decline

While tremendous relief comes from successfully battling cancer, survivors can also experience cognitive impairments caused by the disease and its treatment.

Quitting smoking after cancer diagnosis sharply improves survival, study finds

Postdiagnosis smoking cessation was linked to significantly longer overall survival among cancer patients across all stages, based on real-world electronic health record data. Despite clear survival benefits, only one in five smokers quit within six months of diagnosis, highlighting missed opportunities for intervention.

Proton therapy dose escalation may improve outcomes for glioblastoma patients

Previously, results from the photon cohort of the NRG-BN001, a signal seeking Phase II randomized trial, indicated that photon radiation dose intensification (75 Gy) did not demonstrate improvement in overall survival (OS) for patients with newly diagnosed glioblastoma (GBM).

Stereotactic radiotherapy offers long-term survival outcomes comparable to surgery for NSCLC patients

A new clinical trial report finds that stereotactic radiation therapy offers long-term survival outcomes comparable to surgery for patients with small, early-stage non-small cell lung cancer (NSCLC). Patients in the study who received radiation also reported fewer side effects after treatment.

Proton therapy offers no significant QOL advantage over photon therapy for breast cancer

The first randomized trial to compare photon- and proton-based radiation therapy for breast cancer finds that patients report equally strong health-related quality of life with either treatment. Patients who received proton therapy were more likely to say they would recommend or choose it again, but overall patient-reported outcomes were similar.

Radiation therapy shows promise as safer alternative for severe heart rhythm disorder

Radiation therapy may offer a comparable and potentially safer alternative to repeat catheter ablation for patients with severe abnormal heart rhythms that can no longer be controlled with medication.

Five-session SBRT reduces side effects in intermediate-risk prostate cancer

For patients with intermediate-risk, localized prostate cancer, radiation therapy delivered in five sessions reduced patient-reported side effects compared to longer courses of radiation, according to results of a large, randomized phase III trial.

Post-operative radiation therapy reduces pelvic relapse in high-risk bladder cancer

Radiation therapy could be an underused tool to reduce pelvic relapse risk for patients with locally advanced, muscle-invasive bladder cancer, according to results of a new phase III randomized trial.

Proton therapy and IMRT show similar outcomes in head and neck cancer trial

A new phase III clinical trial finds that intensity-modulated radiation therapy (IMRT) and proton beam therapy resulted in similar quality-of-life outcomes and low rates of side effects for people with locally advanced oropharyngeal cancer.

29 Sep 2025

Gene expression test identifies prostate cancer patients who benefit from hormone therapy

A new randomized study finds that a lab test that reads tumor genes can identify which patients with recurrent prostate cancer will benefit from adding hormone therapy to radiation after surgery - the first predictive biomarker in this setting.

Combining radiopharmaceuticals with targeted radiation improves progression-free survival in prostate cancer patients

A new clinical trial finds that people with a limited number of metastases from recurrent prostate cancer lived significantly longer without disease progression when they received a radiopharmaceutical drug before targeted radiation, compared with radiation alone.

Low-dose radiation therapy may be a suitable option for people with painful knee osteoarthritis

A single course of low-dose radiation therapy may provide a safe and effective alternative treatment option for people with painful knee osteoarthritis according to a new randomized, placebo-controlled clinical trial.

UCLA presents advances in radiation therapy at ASTRO 2025

Physicians and scientists from the UCLA Health Jonsson Comprehensive Cancer Center will share the latest research and clinical trial results at the 2025 American Society for Radiation Oncology (ASTRO) Annual Meeting, including studies on targeted radioactive therapy for recurrent prostate cancer, new approaches to stereotactic body radiation for prostate and head and neck cancers, advances in MRI- and 5DCT-guided imaging for more precise treatments, and innovations in patient-focused cancer education.

Stereotactic body radiation therapy and surgery show similar outcomes for early lung cancer

Researchers from The University of Texas MD Anderson Cancer Center will present new data at the American Society for Radiation Oncology (ASTRO) 2025 Annual Meeting demonstrating that stereotactic body radiation therapy (SBRT) and surgery achieved similar survival outcomes at 10-year follow-up for patients with early-stage non-small cell lung cancer, with radiation offering quality-of-life benefits.

Genomic testing speeds patient accrual in high-risk prostate cancer trial

The NRG Oncology NRG-GU009 (PREDICT-RT) study evaluating intensified and de-intensified concurrent radiation regimens based on the genomic risk of patients with high-risk prostate cancer completed accrual and met its accrual milestone of 2,478 patients approximately two years earlier than the trial's anticipated accrual completion date.

Targeted radiation shows promise for rare solitary fibrous tumors

A novel targeted radiation approach for a rare form of malignant tumor-the solitary fibrous tumor (SFT)-has shown significant success, achieving a near-complete response in three patients.

Study highlights critical mental health risk for eczema patients

A new international study presented today at the European Academy of Dermatology and Venereology (EADV) Congress 2025 reveals that adults with atopic eczema (AE) are significantly more likely to experience suicidal thoughts, with researchers uncovering the key factors driving this elevated risk.

Leading cancer organizations release updated guideline on post-mastectomy radiation therapy

Three leading national cancer organizations today issued an updated guideline on post-mastectomy radiation therapy (PMRT) for physicians treating patients with breast cancer.
