Introduction

In radiotherapy, the emergence of Ultra-High Dose Rate (UHDR) proton irradiation, or FLASH therapy, has gained significant attention for its potential to facilitate treatment modalities. In this work, we present a database derived from a meticulous study of FLASH studies. We aimed to create an easily navigable repository summarising current research and facilitating comparative assessments across experimental procedures and outcomes.

We collected all published papers until March 2024 about FLASH murine studies that directly compared CONV vs UHDR in all irradiation modalities (electrons, protons, carbons and X-rays). The database is continuously updated with new publications. Each experiment's physical and biological parameters must be extracted and listed in the database. Most parameters were documented within the papers; however, specific parameters were not directly provided and required calculations or extraction from plots. The additional information below gives explanations for the calculation and the parameters reported.

With this database, we want to provide a comprehensive overview of FLASH experiments, enabling comparisons of physical and biological parameters across studies. We also want to offer valuable insights for researchers initiating new experiments, potentially helping to reduce endpoint and methodology heterogeneity.

Spreadsheets for analysis

For specific endpoints, we extracted and reported all information into spreadsheets that can be easily used for statistical analysis with any programming language.

Additionally, we provide the Python scripts used for simple endpoint comparisons:
