Interesting item that I don't recall being discussed here, though I don't get here a whole lot anymore. "Single Dose Radiation Therapy", SDRT.
Check this link out: Single-Dose Radiotherapy Produced Similar Safety and Efficacy Data to Stereotactic Body Radiotherapy for Intermediate-Risk Prostate Cancer
From the article:The phase 2 trial investigated the toxic effects, PSA responses, and resulting quality of life measures from SBRT and SDRT, finding that the latter has the potential to be a feasible alternative treatment option for prostate cancer.
When analyzed as a potential alternative to hypofractionated stereotactic body radiotherapy (SBRT), ultra-high single-dose radiotherapy (SDRT) produced similar tumor control and quality-of-life data while maintaining a tolerable safety profile, according to research published in JAMA Oncology.
I had primary RT by IGRT, 44 sessions. A single treatment session would be great, though obviously with such a high single dose the accuracy of delivery would be critical.
