I see wide variance in radiation dose length and total dose.
How is the best dose determined? How does one know if their radiation oncologist is making the best choice?
For example, for consolidative radiation, in STAMPEDE, the dose was 55 Gy in 20 fractions over 4 weeks, or weekly fractions totaling 66 Gy over 6 weeks.
In contrast, PEACE 1 Arm D, not yet reported, used 74 Gy in 37 fractions.
How is the dosing determined? I would appreciate greater clarity on this.
