Al's Comment:

 This is fascinating but needs to be confirmed in larger studies.   For patients with Glioblastoma, they found median OS was 22 months in blood group O whereas 14 months in blood group A, 11 months in blood group B and 6 months in blood group AB.    This could be significant when looking at clinical trial data. Blood type is usually not analyzed but it appears to make a larger difference in survival than any treatment ever tested.
