  • * Grades are 0 = normal; 1 = insignificant visible lesion; 2 = equivocal, needs further follow-up and evaluation; 3 = probably metastasis; and 4 = significant metastasis.

  • In R/T (radiation therapy), No = never treated before, Pelvis = radiation field was confined to pelvis, and L-3/4 or L-1/2 = radiation field was applied up to level of L3 or L1.

  • A = pathologically proven, B = concordant positive findings of 18F-FDG PET and CT or MR images, and C = confirmed by second CT or MRI follow-up.
