Got a guy with multiple recurrences of skin cancer of the scalp who now has brain and bone invasion locally just adjacent to the precentral gyrus. 78yo and a KPS of 70. Anyone think more resection is necessary since they will not resect the area well enough to get a GTR? Should I just do 60 Gy and 30fx and tell neurosurgery to hold off? Can't really find much literature on outcomes once the brain parenchyma is involved by skin cancer.
