How do you contour a resected brain metastases for fractionated partial brain radiation?

When treating a resection cavity in the brain after surgical excision of the tumor, I contour the resection cavity on a Gd-contrast enhanced volumetric MRI. For most large metastases, an average cavity volume reduction of 15% to 43% has been reported in several published studies within 3-4 weeks aft...

If you're just giving 30 in 10, I don't think you have to sweat the details much, after all, you could give the whole brain 30 in 10. If your equipment is limited, you could try a wedged pair or 3 field plan to spare structures like the lens, salivary glands, and hippocampus, if possible. Using 2d o...

I agree with @Dr. First Last's excellent summary.

And @Dr. First Last brings a good point - no need to worry about margins as much or OAR for 30 in 10.

If this was a resected brain metastasis, either offer HA-WBRT (using whole brain as per the initial Patchell study) or use post-operative SRS/SRT...
