Transmission electron microscopy with in situ ion irradiation [PDF]

, 2015
The macroscopic properties of materials exposed to irradiation are determined by radiation damage effects which occur on the nanoscale. These phenomena are complex dynamic processes in which many competing mechanisms contribute to the evolution of the ...

Effects of proton therapy on the tumor immune system and clinical implications: A review

Precision Radiation Oncology, Volume 10, Issue 3, Page 388-402, September 2026.
Proton therapy is a novel radiotherapy technique. We review four aspects of proton therapy: application in various tumors, effects on the tumor immune system, combination with other therapies, and future challenges. By presenting these aspects in this review, we aim to inspire clinical interventions.

The need for the moving junction in craniospinal irradiation.

The British Journal of Radiology, 2000
The moving junction is used in craniospinal irradiation (CSI) to smooth out any dose inhomogeneity across the head/spine junction. The aim of this study was to demonstrate the extent of the head/spine junction inhomogeneity in treatment plans of actual patients and to compare stationary and moving junction data.

The risk of developing a second cancer after receiving craniospinal proton irradiation [PDF]

, 2009
The purpose of this work was to compare the risk of developing a second cancer after craniospinal irradiation using photon versus proton radiotherapy by means of simulation studies designed to account for the effects of neutron exposures.

Molecular and clinical features of a Japanese medulloblastoma cohort: Subgroup‐specific prognostic stratification using economical/accessible diagnostic methods

Brain Pathology, Volume 36, Issue 5, September 2026.
This study characterizes the molecular subgroup–specific features of a nationwide Japanese cohort comprising 242 medulloblastomas (MBs). Furthermore, we introduce SEE‐6‐CNA, a simple, cost‐effective, and FFPE‐compatible molecular test that is applicable to routine pathology samples and serves as a surrogate for risk stratification in non‐WNT/non‐SHH ...

Initial experience of clinical implementation of an Online Simulation‐free CBCT‐based Adaptive Radiotherapy (OSCAR) workflow for palliative and urgent treatment indications

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background The current standard radiotherapy treatment planning workflow typically requires several hours to days, during which patients must wait before treatment can be initiated. In certain oncological situations, however, treatment should commence as soon as possible.

Acute and Chronic Leukemia in Sub‐Saharan Africa: A Systematic Review

Cancer Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background The four primary subgroups of leukemia include chronic myeloid leukemia (CML), acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and chronic lymphocytic leukemia (CLL). Very little is known about the regional variation of leukemia and subtypes in sub‐Saharan Africa (SSA).
