The treatment of ethanol vapors in biotrickling filters for air pollution control was investigated. Two reactors were operated in parallel, one at ambient temperature (22 degrees C) and one at high temperature (53 degrees C). After a short adaptation phase, the removal of ethanol was similar in both reactors. At a bed contact time of 57 s, the elimination(More)
PURPOSE To evaluate acute and late genitourinary (GU) and gastrointestinal (GI) toxicity and biochemical control of hypofractionated, image-guided (fiducial markers or ultrasound guidance), simplified intensity-modulated arc therapy for localized prostate cancer. METHODS AND MATERIALS This Phase II prospective clinical trial for T1a-2cNXM0 prostate cancer(More)
INTRODUCTION Within 10 years of radical prostatectomy (RP), up to 30% of prostate cancer (PCa) patients will have a rise in prostate-specific antigen (PSA), requiring radiation therapy (RT). However, with current technology, distinction between local and distant recurrent PCa is not possible. This lack of an accurate test constrains the decision whether to(More)
OBJECTIVE There is little information available on the treatment of hot flashes in patients refractory to pharmaceutical interventions. Anecdotal evidence led to the use of oxybutynin for the management of hot flashes in refractory cancer patients; therefore, we performed a retrospective chart review of such patients to determine the effect of oxybutynin in(More)
PURPOSE To perform a rigorous technological assessment and statistical validation of a software technology for anatomic delineations of the prostate on MRI datasets. METHODS AND MATERIALS A 3-phase validation strategy was used. Phase I consisted of anatomic atlas building using 100 prostate cancer MRI data sets to provide training data sets for the(More)
BACKGROUND Radiation therapy treatment planning has advanced over the past 2 decades, with increased emphasis on 3-dimensional imaging for target and organ-at-risk (OAR) delineation. Recent studies suggest a need for improved resident instruction in this area. We developed and evaluated an intensive national educational course ("boot camp") designed to(More)
BACKGROUND Prostate bed (PB) contouring is time consuming and associated with inter-observer variability. We evaluated an automated atlas-based segmentation (AABS) engine in its potential to reduce contouring time and inter-observer variability. METHODS An atlas builder (AB) manually contoured the prostate bed, rectum, left femoral head (LFH), right(More)
PURPOSE To initiate a phase 1/2 trial to examine the tolerability of a condensed combined-modality protocol for high-risk prostate cancer. METHODS AND MATERIALS Men scoring ≥3 on the Vulnerable Elderly Scale (VES) or refusing conventionally fractionated treatment for high-risk prostate cancer were eligible to participate. Androgen suppression was(More)
BACKGROUND Survivors of childhood cancer (SCC) who have received radiotherapy to the head, neck, and upper thorax are at higher risk of developing subsequent thyroid malignancies. As part of the post treatment long-term follow-up protocol, the current Children's Oncology Group guideline recommends surveillance by annual palpation; however, thyroid nodules(More)
