Dosimetric evaluation and clinical application of collimated apertures with proton beam line scanning in stereotactic radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Stereotactic radiotherapy (SRT) is a highly effective treatment with precision for small, localized lesions. Proton therapy, characterized by the Bragg peak, offers superior dose conformity compared to photon‐based approaches. However, challenges remain in minimizing lateral penumbra and optimizing dose delivery, particularly for small

Diffusion MR Characteristics Following Concurrent Radiochemotherapy Predicts Progression-Free and Overall Survival in Newly Diagnosed Glioblastoma. [PDF]

open access: yes, 2015
The standard of care for newly diagnosed glioblastoma (GBM) is surgery, then radiotherapy (RT) with concurrent temozolomide (TMZ), followed by adjuvant TMZ. We hypothesized patients with low diffusivity measured using apparent diffusion coefficient (ADC)

An Analysis for IDH‐Mutant Grade 4 Astrocytoma Based on WHO CNS 5: Implication of Clinical Practice

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose There is ongoing debate regarding the therapeutic approach and prognosis for IDH‐mutant grade 4 astrocytoma, a newly defined subtype of diffuse glioma in the 2021 WHO classification system for central nervous system tumors (WHO CNS 5). The aim of this study was to explore the clinical outcome and prognosticators for newly diagnosed IDH‐

The role of surgery in the treatment of older women with breast cancer

open access: yes, 2009
A significant proportion of women diagnosed with breast cancer are over the age of 70 years and there is evidence that these patients frequently do not receive standard treatments, including surgical procedures and adjuvant therapies, which would be ...

Huge decreases in the risk of breast cancer relapse over the last three decades [PDF]

open access: yes, 2013
Introduction The aim of this study was to evaluate local and systemic breast cancer control by comparing the risk of relapse in breast cancer patients in 2003–2004 with that in 1972–1979 and in 1980–1986.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

open access: yesAdvanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Principal causal effect identification and surrogate endpoint evaluation by multiple trials [PDF]

open access: yesarXiv, 2015
Principal stratification is a causal framework to analyze randomized experiments with a post-treatment variable between the treatment and endpoint variables. Because the principal strata defined by the potential outcomes of the post-treatment variable are not observable, we generally cannot identify the causal effects within principal strata. Motivated

Current trends in glioblastoma multiforme treatment: radiation therapy and immune checkpoint inhibitors. [PDF]

open access: yes, 2013
Glioblastoma multiforme (GBM) is the most common primary brain cancer. Even with aggressive combination therapy, the median life expectancy for patients with GBM remains approximately 14 months.
