A 10-year analysis of American Society For Radiation Oncology Junior Faculty Career Development Awards.
Between 2000 and 2010, the American Society for Radiation Oncology (ASTRO) awarded 22 Junior Faculty Career Development Awards (JFA) totaling $4.4 million. This study aimed to evaluate the impact of these awards on the grantees' career development, including current position, publications, and subsequent independent grant funding. ⋯ ASTRO JFAs over the past decade have been strongly associated with grantees remaining in academic positions, success in attracting private and NIH grants, and publication productivity. In an era of dwindling federal research funding, the support provided by the ASTRO JFA may be especially helpful to support the research careers of promising junior faculty members.

Karnofsky performance status and lactate dehydrogenase predict the benefit of palliative whole-brain irradiation in patients with advanced intra- and extracranial metastases from malignant melanoma.
To determine prognostic factors that allow the selection of melanoma patients with advanced intra- and extracerebral metastatic disease for palliative whole-brain radiation therapy (WBRT) or best supportive care. ⋯ Karnofsky performance status and serum LDH values indicate whether patients with advanced intra- and extracranial tumor manifestations are candidates for palliative WBRT or best supportive care.

Randomized Controlled TrialRadiation-free weekend rescued! Continuous accelerated irradiation of 7-days per week is equal to accelerated fractionation with concomitant boost of 7 fractions in 5-days per week: report on phase 3 clinical trial in head-and-neck cancer patients.
To report long-term results of randomized trial comparing 2 accelerated fractionations of definitive radiation therapy assessing the need to irradiate during weekend in patients with head and neck squamous cell carcinoma. ⋯ Results of this trial indicate that the effects of accelerated fractionation can be achieve by delivering twice-per-day irradiation on weekday(s). This trial has also confirmed that an accelerated, 6-weeks schedule is a reasonable option for patients with intermediate-stage head-and-neck squamous cell carcinoma because of the associated high cure rate and minimal severe late toxicity.

Gamma knife radiosurgery for the treatment of cystic cerebral metastases.
To assess the role of Gamma Knife radiosurgery (GKRS) in the treatment of nonsurgical cystic brain metastasis, and to determine predictors of response to GKRS. ⋯ This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates.
