Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

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

European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) position paper on screening, diagnosis and investigation of paediatric metabolic dysfunction‐associated steatotic liver disease

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Metabolic dysfunction‐associated steatotic liver disease (MASLD) is the most common reason for elevated liver enzymes in children in Europe, affecting more than 5% of all children. Since the last iteration of this position paper, there have been substantial advances in our understanding of the disease.

Predictive Value of Nutrition Indices in Advanced Hepatocellular Carcinoma Patients Treated With Lenvatinib

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prognostic nutritional index (PNI) and geriatric nutritional risk index (GNRI) are simple markers that reflect immune and nutritional status. This retrospective study evaluated their prognostic significance in 276 patients with advanced hepatocellular carcinoma (HCC) who received first‐line lenvatinib. PNI and GNRI were calculated based on

The Natural History of Residual and Recurrent Disease in Advanced Juvenile Nasopharyngeal Angiofibroma: A Systematic Review

The Laryngoscope, EarlyView.
Residual and recurrent disease in advanced juvenile nasopharyngeal angiofibromas (JNAs) demonstrate spontaneous involution, reduction in size, or long‐term stability following initial treatment in 95% of patients. In this systematic review of 131 patients with advanced JNA, only 2% of patients demonstrated disease progression during surveillance, but ...

Is Proton Therapy Superior to Gamma Knife Radiosurgery for Sporadic Vestibular Schwannoma?

The Laryngoscope, EarlyView.
With changing practice patterns, radiation therapy for vestibular schwannomas has become an increasingly utilized treatment modality with high tumor control rates. Gamma‐Knife radiosurgery remains a well‐established and readily accessible option with good rates for tumor control, cranial nerve preservation, and hearing outcomes.

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 ...

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

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.
