Emergence of FLASH‑radiotherapy across the last 50 years (Review).

ABSTRACT: A novel radiotherapy (RT) approach termed FLASH-RT, which irradiates areas at ultra-high dose rates, is of current interest to medical researchers. FLASH-RT can maintain equivalent antitumor effects while sparing healthy tissue compared with conventional RT (CONV-RT), which uses low dose rates. The sparing effect on healthy tissue after FLASH-RT is known as the FLASH effect. Owing to the FLASH effect, FLASH-RT can raise the maximum tolerable dose to control tumor growth or eradicate the tumor and provide a new strategy for clinical RT. However, definitive irradiation conditions for reproducing the FLASH effect and the biological mechanism of the FLASH effect have not yet been fully elucidated. The efficacy of FLASH-RT is controversial despite its successful application in clinical RT. The
