Hypoxic tumors are sensitive to FLASH radiotherapy
Localized FLASH Radiotherapy Reduces Long-Term Skin and Muscle Damage While Preserving Systemic Homeostasis
Radiotherapy (RT) is a cornerstone treatment for nearly 50% of cancer patients, yet its efficacy remains limited by cumulative damage to healthy tissues over time. Delivering RT at ultra-high dose rates (FLASH-RT) represents a transformative strategy, as it appears to maintain tumor control, while s...

Differential impact of FLASH and conventional radiotherapy on a pivotal metabolic organ: White Adipose Tissue
Purpose: Tumor hypoxia is a major cause of treatment resistance, especially to radiation therapy at conventional dose rate (CONV), and we wanted to assess whether hypoxia does alter tumor sensitivity to FLASH. Methods and materials: We engrafted several tumor types (glioblastoma [GBM], head and neck...

Evaluation of the late genotoxic effect of flash radiation therapy in mouse tissue
This study aims to assess the effect of conventional radiotherapy compared to FLASH radiotherapy on healthy human lung tissue. FLASH radiotherapy, characterized by ultra-high dose rates, is hypothesized to spare healthy tissue from radiation-induced damage while maintaining efficacy against tumors. ...
