Efficacy of immune checkpoint inhibitors according to PD‐L1 tumor proportion scores in non‐small cell lung cancer
Background We correlated the tumor proportion score (TPS) of programmed cell death ligand 1 (PD‐L1, SP263 or 22C3) expression with the disease control rate (DCR, partial remission and stable disease), and progression free survival (PFS) after nivolumab or pembrolizumab treatment. Methods A total of...

Zusammenfassung: | Background
We correlated the tumor proportion score (TPS) of programmed cell death ligand 1 (PD‐L1, SP263 or 22C3) expression with the disease control rate (DCR, partial remission and stable disease), and progression free survival (PFS) after nivolumab or pembrolizumab treatment.
Methods
A total of 70 case records (55 males, 15 females) of patients with non‐small cell lung cancer (NSCLC, 46 adenocarcinoma, 22 squamous cell carcinoma, and two others) were reviewed. The PD‐L1 expressions were divided into High (SP263 ≥ 30%, 22C3 ≥ 80%) and Low groups (SP263 |
