CD8A and chondrosarcoma: A comparison of the TILs within conventional chondrosarcoma showed that grade 3 tumors had higher CD8+ TILs than grade 1 or 2 tumors: mean 3.4 ± 6.1 (range, 0-14, n=5) lymphocytes per high-power field versus 0.26 ± 1.3 (range, 0-7.6, n=37) lymphocytes per high-power field, (p=0.014).
