A first human test of ultra-fast and ultra-powerful proton beam radiotherapy suggests that this novel technique may be the way of the future.  University of Cincinnati radiation oncologists report their preliminary phase 1 trial results to the American Society for Radiation Oncology’s (ASTRO) Annual Meeting.

 

Ten patients 27-81 years of age with painful extremity bony metastases at 12 sites were treated with a whopping 8 Gy of radiation at greater than 40 Gy per second in about 3/10ths of a second.  This dose rate is 300 times higher than the conventional rate.  When these patients’ use of pain meds was recorded at varying intervals up to 13 months following therapy, 7 of the 10 patients enjoyed complete or significant partial pain relief.

 

The best news: this FLASH technique spares normal, non-cancerous tissue better than conventional radiation therapy.
