Long-Term Survival Rates More Than Double Previous Estimates for Locally Advanced Lung Cancer

Excerpt:

“Long-term results of a phase III clinical trial indicate that survival rates for patients receiving chemoradiation for unresectable, locally advanced non-small cell lung cancer (NSCLC) may be more than twice as high as previous estimates. At five years following treatment with a standard dose of 60 Gray (Gy) radiation delivered in 30 fractions, the overall survival rate was 32 percent, setting a new benchmark of survival for patients with inoperable stage III NSCLC. The trial, RTOG 0617, also confirms that a standard dose of radiation therapy is preferable to a higher dose and that cetuximab offers no additional survival benefit for these patients. Findings will be presented today at the 59th Annual Meeting of the American Society for Radiation Oncology (ASTRO) in San Diego.”

Radiation Therapy Can Enhance Effectiveness of Immunotherapy in People With Advanced Lung Cancer, UCLA Study Finds

Excerpt:

“A new study by UCLA scientists has found that the breakthrough immunotherapy drug pembrolizumab can be more effective in improving survival in people with non-small cell lung cancer (NSCLC) if they have previously received radiation therapy, compared to those without a history of radiation treatment. The findings are important as the strategies of combining radiation therapy with anti-PD-1 antibodies such as pembrolizumb are currently being explored, and have the potential to increase the overall benefit of immunotherapy for people with NSCLC, the most common form of lung cancer.”

A New Prognostic Classification May Help Clinical Decision-Making in Glioblastoma

Excerpt:

“New research shows that taking molecular variables into account will improve the prognostic classification of the lethal brain cancer called glioblastoma (GBM).

“The study was led by researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).

“Published in the journal JAMA Oncology, the study found that adding significant molecular biomarkers to the existing GBM classification system improves the prognostic classification of GBM patients who have been treated with radiation and the drug temozolomide.”

Older Women with Breast Cancer Report Better Cosmetic Satisfaction with Less Radiation, Less Surgery

Excerpt:

“In the first study evaluating patient-reported cosmetic outcomes in a population-based cohort of older women with breast cancer, The University of Texas MD Anderson Cancer Center researchers found that less radiation was associated with improved cosmetic satisfaction long-term. However, reduced radiation was also associated with a slightly increased risk of disease recurrence.

“The findings, presented at the 2016 San Antonio Breast Cancer Symposium in a poster session by Cameron W. Swanick, M.D., should serve as an important discussion point between older patients and their physicians when making treatment decisions.”

Study Shows Strong Evidence Supporting Radiation Boost to Tumor Bed in Ductal Carcinoma in Situ

Excerpt:

“A radiation boost to the local tumor bed following treatment with breast-conserving therapy (ie, local excision followed by whole-breast radiation therapy) improves local control for patients with ductal carcinoma in situ, according to a study of pooled data from 10 academic centers, presented at the 58th Annual Meeting of the American Society of Radiation Oncology (ASTRO). The magnitude of improvement is similar to that seen for a radiation boost in invasive breast cancer.”

Benefit of Radiation Boost in DCIS Validated

Excerpt:

“A radiation boost to the tumor bed led to a small but statistically significant reduction in breast cancer recurrence after breast-conserving therapy for ductal carcinoma in situ (DCIS), a randomized study showed.

“Women who received the radiation boost had a 15-year freedom from ipsilateral recurrence of 91.6% compared with 88.0% for patients who had lumpectomy and adjuvant irradiation but not boost to the tumor bed. The additional protection afforded by the radiation boost encompassed both DCIS and invasive recurrence.”

Intermediate Risk Prostate Cancer May Be Well Controlled with Brachytherapy Alone

Excerpt:

“For men with intermediate risk prostate cancer, radiation treatment with brachytherapy alone can result in similar cancer control with fewer long-term side effects, when compared to more aggressive treatment that combines brachytherapy with external beam therapy (EBT), according to research presented today at the 58th Annual Meeting the American Society for Radiation Oncology (ASTRO).”

Immune and Targeted Therapies Combined with Radiation Therapy Improves Outcomes for Melanoma Brain Metastases Patients, Say Moffitt Researchers

Excerpt:

“Brain metastases are one of the most common complications of advanced melanoma, requiring multidisciplinary management. Patients who are diagnosed with these metastases have an expected median survival of only 4 to 5 months. Moffitt Cancer Center researchers hope to improve these survival rates following a new study in Annals of Oncology that shows novel immune and targeted therapies with radiation therapy improves the outcomes of patients with melanoma brain metastases over conventional chemotherapy.”

Hypofractionation May Be Poised to Become New Standard of Care for Prostate Cancer

Excerpt:

“There has been an ongoing debate about which type of radiation therapy is preferable in the treatment of localized prostate cancer: hypofractionation (larger fractions given over 4–5 weeks) or conventional radiotherapy (given over 8–9 weeks). A new study presented at the 2016 ASCO Annual Meeting may help to resolve that debate.

“The large, randomized trial found that hypofractionation was not inferior to conventional radiation therapy in terms of efficacy or safety in men with localized intermediate-risk prostate cancer. This is the third large, randomized, contemporary study to demonstrate that both techniques have equivalent efficacy and safety.”
