BACKGROUND Melanoma and renal cell carcinoma (RCC) are traditionally considered less radioresponsive than other histologies. Whereas stereotactic body radiation therapy (SBRT) involves radiation dose intensification via escalation, we hypothesize SBRT might result in similar high local control rates as previously published on metastases of varying(More)
PURPOSE To characterize changes in standardized uptake value (SUV) in positron emission tomography (PET) scans and determine the pace of normal tissue regeneration after stereotactic body radiation therapy (SBRT) for solid tumor liver metastases. METHODS AND MATERIALS We reviewed records of patients with liver metastases treated with SBRT to ≥40 Gy in 3-5(More)
BACKGROUND Autogenous vein grafts are commonly used for arterial reconstructive procedures. Their success is limited by the development of intimal hyperplasia (IH), a fibroproliferative disease that predisposes the grafts to occlusive stenosis. Mesenchymal cell proliferation and the deposition of an extracellular matrix characterize neointimal development.(More)
A novel intensity-modulated radiation therapy (IMRT) phantom for use in three-dimensional in vitro cell experiments, based on a commercially available system (CIRS Inc., Norfolk, VA), was designed and fabricated. The water-equivalent plastic phantom can, with a set of water-equivalent plastic inserts, enclose 1-3 multi-well tissue culture plates. Dosimetry(More)
PURPOSE To compare volumetric modulated arc therapy (VMAT) with 3-dimensional conformal radiation therapy (3D-CRT) in the treatment of localized intracranial germinoma. We modeled the effect of the dosimetric differences on intelligence quotient (IQ). METHOD AND MATERIALS Ten children with intracranial germinomas were used for planning. The prescription(More)
PURPOSE To experimentally validate how temporal modification of the applied dose pattern within a single fraction of radiation therapy affects cell survival. METHOD AND MATERIALS Using the linear-quadratic model, we have previously demonstrated that the greatest difference in cell survival results from comparing a temporal dose pattern delivering the(More)
Approximately 20% of children with Ewing sarcoma (EWS) and rhabdomyosarcoma (RMS) present with metastatic disease at initial diagnosis. Overall, the outcome is poor, with an event-free survival of < 20%. Local control at metastatic sites has not been previously reported. We reviewed control of metastatic sites in children with EWS and RMS that received(More)
PURPOSE To evaluate the temporal dose response of normal liver tissue for patients with liver metastases treated with stereotactic body radiation therapy (SBRT). METHODS AND MATERIALS Ninety-nine noncontrast follow-up computed tomography (CT) scans of 34 patients who received SBRT between 2004 and 2011 were retrospectively analyzed at a median of 8 months(More)
Patients with medically inoperable early stage nonsmall cell lung cancer are now routinely offered definitive treatment with stereotactic body radiation therapy (SBRT), which achieves excellent local control and provides a 3-year survival on the order of 60%, with less than 5% chance of severe toxicity. 1,2 However, the same medical comorbidities that make(More)
