Abstract
Flash radiotherapy (Flash-RT) is a treatment modality that uses the normal tissue sparing regimen induced by ultra-high dose rate and ultra-fast irradiation. Compared to conventional dose rate radiotherapy, Flash-RT has the potential to provide the isoefficacy for tumors while achieving the remarkable normal tissue protection. Due to this unique feature, Flash-RT is attracting more and more attention from the radiotherapy community. An abundance of groups from both academia and industry are extensively studying the therapeutic ratio and underlying biological mechanisms. Here, we review the prior knowledge about Flash-RT and summarize the results that have been reported from various groups using both in vitro and animal studies with different experimental protocols. We also discuss possible biological mechanisms and the challenging of implementing Flash-RT, as well as its possible options for clinical applications.
Key words:
Flash radiotherapy; Dose rate; Dosimetry; Hypoxia; Ultra-fast irradiation
期刊介绍:
The Chinese Journal of Radiation Oncology is a national academic journal sponsored by the Chinese Medical Association. It was founded in 1992 and the title was written by Chen Minzhang, the former Minister of Health. Its predecessor was the Chinese Journal of Radiation Oncology, which was founded in 1987. The journal is an authoritative journal in the field of radiation oncology in my country. It focuses on clinical tumor radiotherapy, tumor radiation physics, tumor radiation biology, and thermal therapy. Its main readers are middle and senior clinical doctors and scientific researchers. It is now a monthly journal with a large 16-page format and 80 pages of text. For many years, it has adhered to the principle of combining theory with practice and combining improvement with popularization. It now has columns such as monographs, head and neck tumors (monographs), chest tumors (monographs), abdominal tumors (monographs), physics, technology, biology (monographs), reviews, and investigations and research.
