Is it appropriate to use a hypofractionated regimen to treat the pelvic nodes in prostate cancer?
For example, for the first 25 fractions, you would treat the rest of the pelvis in 1.8 Gy/fx to 45 Gy, and then using a SIB treat the prostate/proximal SV at 2.5 Gy/fx to 62.5 Gy. Then boost the prostate/prox SV for additional 3 fractions, for 7.5 Gy for a total of 70 Gy.
Answer from: Radiation Oncologist at Community Practice
Much of the world uses 60 Gy in 20 fractions as their new standard of care, which is endorsed by nearly all guidelines. When treating nodes people simply use 2.1 or 2.2 Gy per fraction to 42 to 44 Gy in 20 fractions simultaneously to the nodes. It is near identical to the 1.8 Gy to 45 Gy so not rea...

Answer from: Radiation Oncologist at Academic Institution
Radiation oncologists have a lot of freedom to use our alpha-beta model to create innovative fractionation schemes. We know that hypofractionation to the prostate is safe and effective at 2.5 Gy/fx to 70 Gy and 3 Gy/fx to 60 Gy. We also know that 1.8 Gy/fx to the pelvic nodal regions is a well estab...
