Mathematical methods and models for radiation carcinogenesis studies [PDF]

, 1986
Research on radiation carcinogenesis requires a twofold approach. Studies of primary molecular lesions and subsequent cytogenetic changes are essential, but they cannot at present provide numerical estimates of the risk of small doses of ionizing ...

Targeting m6A Reader YTHDF1 Enhances Antitumor Immunity and Potentiates Anti‐PD‐L1 Efficacy in Intrahepatic Cholangiocarcinoma

Advanced Science, EarlyView.
The m6A reader YTHDF1 drives intrahepatic cholangiocarcinoma (ICC) progression by remodeling the tumor immune microenvironment. YTHDF1 promotes MDSC recruitment via activation of m6A‐FOSL2‐CXCL6/CXCR2 axis, thereby suppressing CD8+ T cell infiltration and function.

Brachial Plexopathy in Head and Neck Cancer Potentially Related to LET-Dependent RBE

Biophysica
Proton beam therapy for head and neck cancers traditionally employs a fixed relative biological effectiveness (RBE) of 1.1, which may underestimate actual biological effects in critical structures.

Absence of a dose-rate effect in the transformation of C3H 10T1/2 cells by α-particles [PDF]

, 1987
The findings of Hill et al. (1984) on the greatly enhanced transformation frequencies at very low dose rates of fission neutrons induced us to perform an analogous study with -particles at comparable dose rates. Transformation frequencies were determined

Bacterial Pigments as Potential Antitumor Agents Against Gastrointestinal Cancers: A Comprehensive Systematic Review

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Gastrointestinal cancers (GICs) constitute one of the leading causes of cancer‐related morbidity and mortality worldwide. Despite currently available therapeutic strategies, new approaches and procedures are needed for their prevention and treatment.

Recommendations for reporting and evaluating proton therapy beyond dose and constant relative biological effectiveness

Physics and Imaging in Radiation Oncology
Background and purpose: In proton therapy, a relative biological effectiveness (RBE) of 1.1 is used to convert proton dose into an equivalent photon dose.

Estimation of biological effect of Cu-64 radiopharmaceuticals with Geant4-DNA simulation

Scientific Reports, 2022
The aim of this work is to estimate the biological effect of targeted radionuclide therapy using Cu-64, which is a well-known Auger electron emitter. To do so, we evaluate the absorbed dose of emitted particles from Cu-64 using the Geant4-DNA Monte Carlo

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 ...

Predicting the Biological Effects of Human Salivary Gland Tumour Cells for Scanned ⁴He-, ¹²C-, ¹⁶O-, and ²⁰Ne-Ion Beams Using an SOI Microdosimeter

Applied Sciences, 2022
Experimental microdosimetry along with the microdosimetric kinetic (MK) model can be utilized to predict the biological effects of ions. To predict the relative biological effectiveness (RBE) of ions and the survival fraction (SF) of human salivary gland

Combining radiotherapy with CAR‐T cell therapy for solid tumors: Challenges, mechanisms, and future directions

Precision Radiation Oncology, EarlyView.
Radiotherapy enhances CAR‐Tcell therapy by increasing antigenicity, improving trafficking, and reshaping the tumor microenvironment. Despite its dual effects, including potential immune suppression, understanding these mechanisms enables the development of strategies to maximize synergy in solid tumors.
