PD-1 and PD-L1 Expression in NSCLC Indicate a Favorable Prognosis in Defined Subgroups
<div><p>Background</p><p>Immunotherapy can become a crucial therapeutic option to improve prognosis for lung cancer patients. First clinical trials with therapies targeting the programmed cell death receptor PD-1 and its ligand PD-L1 have shown promising results in several solid tumors. However, in lung cancer the diagnostic, prognostic and predictive value of these immunologic factors remains unclear.</p><p>Method</p><p>The impact of both factors was evaluated in a study collective of 321 clinically well-annotated patients with non-small lung cancer (NSCLC) using immunohistochemistry.</p><p>Results</p><p>PD-1 expression by tumor infiltrating lymphocytes (TILs) was found in 22%, whereas tumor cell associated PD-L1 expression was observed in 24% of the NSCLC tumors. In Fisherâs exact test a positive correlation was found for PD-L1 and Bcl-xl protein expression (p = 0.013). Interestingly, PD-L1 expression on tumor cells was associated with improved overall survival in pulmonary squamous cell carcinomas (SCC, p = 0.042, log rank test), with adjuvant therapy (p = 0.017), with increased tumor size (pT2-4, p = 0.039) and with positive lymph node status (pN1-3, p = 0.010). These observations were confirmed by multivariate cox regression models.</p><p>Conclusion</p><p>One major finding of our study is the identification of a prognostic implication of PD-L1 in subsets of NSCLC patients with pulmonary SCC, with increased tumor size, with a positive lymph node status and NSCLC patients who received adjuvant therapies. This study provides first data for immune-context related risk stratification of NSCLC patients. Further studies are necessary both to confirm this observation and to evaluate the predictive value of PD-1 and PD-L1 in NSCLC in the context of PD-1 inhibition.</p></div

<p>Included variables: sex (male (ref.) <i>vs</i>. female), age (< 80 years (ref.) <i>vs</i>. â„ 80 years), LVEF (as a continuous variable), LVEF (LVEF < 45% (ref.) <i>vs</i>. â„ 45%); previous malignancy (no previous (ref.) malignancy <i>vs</i>. previous malignancy); SPN (no SPN (ref.) <i>vs</i>. SPN â„ 5 mm and all others (ref.) <i>vs</i>.

Prognostic impact of PD-L1 expression by tumor cells depends on tumor histology.
<p>Whereas for the full study collective (n = 321 patients), no prognostic effect was found, neither for PD-1 (A) nor for PD-L1 (B), patients who received adjuvant therapy (C), patients with pulmonary squamous cell carcinomas (D), patients with pT2-T4 tumors (E) and patients with a positive lymph node status (pN1-3, F) had an increased overall survival.</p
