This study is a long-term analysis of RTOG 9903, originally published in 2007[1], to determine if there were additional failures, second primaries and/or toxicities at a longer follow-up of eight years. RTOG 9903, an open-label, Phase 3 randomized trial, examined if the addition of EPO, which stimulates the bodys bone marrow to increase red blood cell production to prevent and to treat anemia, to radiation therapy would improve disease control in anemic patients with HNSCCa.

Radio Astronomy in Africa: The Case of Ghana

Bernard Duah Asabere, Michael Gaylard, Cathy Horellou, Hartmut Winkler, Thomas Jarrett (Submitted on 30 Mar 2015) South Africa has played a leading role in radio astronomy in Africa with the Hartebeesthoek Radio Astronomy Observatory (HartRAO). It continues to make strides with the current seven-dish MeerKAT precursor array (KAT-7), leading to the 64-dish MeerKAT and the giant Square Kilometer Array (SKA), which will be used for transformational radio astronomy research. Ghana, an African partner to the SKA, has been mentored by South Africa over the past six years and will soon emerge in the field of radio astronomy Continue reading

ASTRO applauds CMS's decision to cover annual, LDCT screening for high-risk lung cancer patients

Fairfax, Va., February 9, 2014 – The American Society for Radiation Oncology (ASTRO) commends the February 5, 2015, decision by the Centers for Medicare and Medicaid Services (CMS) to provide coverage for annual lung cancer screening via low-dose CT screening for those at highest-risk for lung cancer. The final Decision Memo for Screening for Lung Cancer with Low Dose Computed Tomography (LDCT) (CAG-00439N) details that there is sufficient evidence to warrant annual lung cancer screening for patients most at-risk for developing lung cancer.
