0001), but it was not associated with PD-L1 expression (p=0.296) or immune cell infiltrates (p=0.619). In recurrent SFTP, PD-L1 was expressed in 4 of 10 (40%) tumors (all 1% expression). There was no correlation in PD-L1 expression between primary and recurrent SFTP samples. A small subset of SFTPs express PD-L1 at low levels (1%) but exhibit colocalization of CD8 immune cells suggesting an inducible expression mechanism. The role of PD-L1 merits exploration in the clinical setting in patients with advanced SFTP w
