RefleXion debuts at ASTRO with PET-guided rad therapy

October 23, 2018 -- SAN ANTONIO - What if you could take cancer's natural activity in the human body and turn it back on itself? That's the premise behind RefleXion, which made its debut at this week's American Society for Radiation Oncology (ASTRO) meeting with a PET-guided radiation therapy system. Discuss

ASTRO: SABR is effective for oligometastatic cancers

October 23, 2018 -- Stereotactic ablative radiotherapy (SABR) can greatly increase how long oligometastatic patients survive and doubles how long they live without cancer, according to new research presented at this week's American Society for Radiation Oncology (ASTRO) meeting. Discuss

October 23, 2018 -- SAN ANTONIO - Radiation therapy (RT) could be more effective in African-American men with prostate cancer than previously realized, according to data presented on Monday at the American Society for Radiation Oncology (ASTRO) annual meeting. Discuss

Can whole-body MRI be used in oncologic staging?

October 23, 2018 -- Offering similar performance to PET/CT but without requiring radiation dose, multiparametric whole-body MRI could feasibly be used for staging metastatic lesions and evaluating treatment response in a variety of cancers, according to a study published in the November issue of Academic Radiology.

ASTRO: AI's rad therapy future is in predicting outcomes

October 22, 2018 -- SAN ANTONIO - Radiation oncology is already putting artificial intelligence (AI) to work by using the technology for automating mundane tasks. But AI's real value will come when it is able to accurately predict patient outcomes, according to a Sunday talk at the American Society for Radiation Oncology (ASTRO) annual meeting. Discuss

Key MRI markers link vascular brain injury to health risks

October 22, 2018 -- Which MRI markers of vascular brain injury are most significantly associated with a greater risk for stroke, dementia, and death in older adults? If you answered white-matter hyperintensities, brain infarcts, and cerebral microbleeds, your conclusion matches the findings of a meta-analysis published online October 22 in JAMA Neurology. Discuss

Study gives all-clear for skin cream during radiation therapy

October 19, 2018 -- It's OK for patients scheduled for radiation therapy to apply topical treatments such as skin cream in moderation before their procedures, according to a study published October 16 in JAMA Oncology.
