Table 2. Expression of CD8+ and PD-L1 in primary, recurrent, and metastatic MPNST.
| Primary MPNST | Recurrent MPNST | Metastatic MPNST | ||
|---|---|---|---|---|
| PD-L1 | PD-L1 (1%) = 2/10 | PD-L1 (5%) = 2/10 | PD-L1 (1%) = 0/5 | PD-L1 (5%) = 0/5 |
| PD-L1 (1%) = 7/38 | p=0.909 | p=0.294 | ||
| PD-L1 (5%) = 5/38 | p=0.585 | p=0.388 | ||
| CD8+ | CD8+ (1%) = 8/10 | CD8+ (5%) = 2/10 | CD8+ (1%) = 2/5 | CD8+ (5%) = 0/5 |
| CD8+ (1%) = 20/38 | p=0.118 | p=0.595 | ||
| CD8+ (5%) = 9/38 | p=0.805 | p=0.221 | ||
No significant differences were noted in the expression level of PD-L1 or the amount of CD8+ lymphocytes between primary and recurrent or metastatic MPNST samples.
