background: the locally advanced head and neck cancer with fixed nodes are incurable and has a short survival. this study aims to evaluate the symptom relief, disease response and acute toxicity after palliative hypofractionated radiotherapy. methods: between december 2010 to june 2011, previously untreated 50 patients who had histopathologically proved of head and neck squamous cell carcinoma ...

PURPOSE To evaluate dosimetric coverage of the prostate, normal tissue sparing, and acute toxicity with HDR brachytherapy for large prostate volumes. MATERIALS AND METHODS One hundred and two prostate cancer patients with prostate volumes >50 mL (range: 5-29 mL) were treated with high-dose-rate (HDR) brachytherapy ± intensity modulated radiation therapy (IMRT) to 4,500 cGy in 25 daily fractio...

BACKGROUND Clinical data indicates that delivery of larger daily doses of radiation may improve the therapeutic ratio for prostate cancer compared to conventional fractionation. A phase II study of stereotactic body radiotherapy with real-time motion management and daily plan re-optimization for low to intermediate risk prostate cancer was undertaken to evaluate this hypothesis. This report det...

objective(s): drug addiction is one of the fastest growing social problems that researchers, for many years, have been trying to find proper strategies for its prevention and treatment. short-term physical activity is considered as acceptable for the treatment and prevention of addiction. on the other hand, prefrontal cortex is known to be responsible for many of the complex behavioral response...

BACKGROUND To assess acute (primary endpoint) and late toxicity, quality of life (QOL), biochemical or clinical failure (secondary endpoints) of a hypofractionated IMRT schedule for prostate cancer (PC). METHODS 38 men with localized PC received 66 Gy (2.64 Gy) to prostate,2 Gy to seminal vesicles (50 Gy total) using IMRT.Acute toxicity was evaluated weekly during radiotherapy (RT), at 1-3 mo...

in schizophrenia, neurocognitive functions are one to two standard deviations below the normal controls and these deficits have a significant relationship with overall functioning and poor outcome. according to this fact, it is important to investigate the factors that effect neurocognition in schizophrenic patients. this study was carried out to demonstrate the relationship between attention/v...

BACKGROUND/PURPOSE To review the efficacy and toxicity of palliative radiotherapy (RT) for symptomatic locally advanced gastric cancer (GC) and to determine the optimal RT schedule for symptom palliation. METHODS We searched MEDLINE and CENTRAL for eligible studies published from 1995 to 2015. Outcomes of interest were relief of bleeding, pain and obstruction. RESULTS Seven non-comparative ...

Systemic therapy using bone-seeking radiopharmaceuticals has clear advantages for the treatment of multisite metastatic pain. Evidence supporting the use of beta-particle, electron, and alpha-particle-emitting radiopharmaceuticals is reviewed here. Appropriate patient selection relies on correlating clinical symptoms with focal abnormalities on conventional bone scintigraphy. Time to symptom re...
