High dose hypofractionated proton beam therapy is a safe and feasible treatment for central lung cancer

Radiology and Oncology, 2017
There have been few reports about high total dose hypofractionated proton beam therapy for central lung cancer. The aim of this study was to examine retrospectively the safety and efficacy of high total dose hypofractionated proton beam therapy for ...

Fraction-variant beam orientation optimization for non-coplanar IMRT

, 2017
Conventional beam orientation optimization (BOO) algorithms for IMRT assume that the same set of beam angles is used for all treatment fractions. In this paper we present a BOO formulation based on group sparsity that simultaneously optimizes non ...

Proton beam therapy facility [PDF]

, 1984
It is proposed to build a regional outpatient medical clinic at the Fermi National Accelerator Laboratory (Fermilab), Batavia, Illinois, to exploit the unique therapeutic characteristics of high energy proton beams. The Fermilab location for a proton therapy facility (PTF) is being chosen for reasons ranging from lower total construction and operating ...

Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy

Boost Approaches in Patients Undergoing Postoperative Radiotherapy

Journal of Surgical Oncology, EarlyView.
ABSTRACT The use of breast conservation surgery for early‐stage breast cancer is common, and adjuvant radiotherapy is often recommended to reduce the risk of ipsilateral breast tumor recurrence. Historical trials have used sequential boost techniques with favorable outcomes with reduction in local recurrence and acceptable cosmetic outcomes.

Enriched Environment Enhances Motor Function in Mice With Cerebral Infarction by Promoting mTOR‐Dependent Autophagy in the Contralateral Dentate Nucleus

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Although environmental enrichment (EE) promotes post‐stroke motor recovery, the mechanisms underlying its regulation of cerebellar dentate nucleus (DN) plasticity remain unclear; this study therefore investigated how EE coordinates autophagy, mitochondrial homeostasis, and synaptic remodeling in the contralateral DN to facilitate functional ...

Proton beam therapy achieves excellent local control for recurrent epithelial ovarian cancer: a single-center retrospective study

Journal of Ovarian Research
Background Previous studies have demonstrated the benefit of radiation therapy for patients with recurrent epithelial ovarian cancer; however, the effects of proton beam therapy in these patients remain unelucidated.

Recurrent Maxillary Ameloblastoma Presenting as an External Auditory Canal Mass

The Laryngoscope, EarlyView.
Ameloblastoma with temporal bone involvement is exceedingly rare, with no prior reports of external auditory canal presentation. This case report demonstrates successful multidisciplinary management with extensive skull base resection and adjuvant radiation therapy, emphasizing the role of proton therapy in achieving tissue‐sparing treatment and long ...

Monte Carlo calculated CT numbers for improved heavy ion treatment planning

Nukleonika, 2014
Better knowledge of CT number values and their uncertainties can be applied to improve heavy ion treatment planning. We developed a novel method to calculate CT numbers for a computed tomography (CT) scanner using the Monte Carlo (MC) code, BEAMnrc ...

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances

Mass Spectrometry Reviews, EarlyView.
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.
