BackgroundImmunotherapy is a promising advance in oncology. Limited information exists regarding the interrelationship between CD47 expression and tumour-associated macrophage-related immuno-microenvironment in patients with non-small cell lung cancer (NSCLC). These factors may predict novel immunotherapy efficacy.Patients and methodsCD47 and PD-L1 expression was retrospectively assessed in 191 resected NSCLC specimens via immunohistochemistry. Forty-six patients with pulmonary infectious diseases were enrolled as the control group. The infiltration of macrophages (M2 and M1) and CD8+ T-lymphocytes was evaluated via dual-immunofluorescence staining. Targeted DNA sequencing was performed on NSCLC specimens. Survival analysis was performed using the Cox model.ResultsUsing 2+/3+ as a CD47 positive (CD47pos) expression cut-off, the prevalence of CD47pos expression in NSCLC was 33.0% (63/191), significantly higher than in pulmonary infectious diseases. CD47pos expression was significantly higher in female, non-smoking and adenocarcinoma patients (p=0.020, p<0.001 and p<0.001, respectively). Furthermore, CD47pos expression was significantly correlated with epidermal growth factor receptor mutation (p<0.001). The expression of CD47 (H-score) in NSCLC was negatively correlated with tumour PD-L1 expression (p=0.0346) and tumour mutation burden (p=0.0107). CD47pos expression was independently correlated with poor disease-free survival in patients with resected NSCLC in multivariate Cox regression analysis (p=0.035).ConclusionThis study revealed the demographic, molecular and immuno-microenvironment characteristics of CD47 expression in NSCLC. We identified tumour CD47pos expression as an independent prognostic factor for recurrence in resected NSCLC. Our findings illustrate the potential of anti-CD47 treatment in NSCLC.

e17540 Background: The hepatocyte growth factor/MET pathway has been shown to cause tumor progression in several types of carcinomas. We reported that c-Met up-regulated topoisomease I (Topo I) in non-small cell lung cancer cell lines (submitted for publication). The aims of this study were 1) to examine the prognostic influence of c-MET/phospho-MET (p-Met), or Topo I expression and 2) to elucidate correlation between c-Met/p-Met expression and Topo I expression in small cell lung cancer (SCLC). Methods: This retrospective study included 72 SCLC patients (pts) with available tumor tissue from primary lung tumor or metastatic lesions and clinical data including survival. We performed immunohistochemistry to detect c-MET/phospho-MET and Topo I expression. Results: Tumor tissues were obtained from 72 SCLC pts. Sixty-six pts, (51 male, 15 female, median age 67.5 range 43-91, LD/ED 38/28, PS0,1/2,3,4 57/9) were evaluated. c-Met overexpression was seen in 40.9%, p-Met in 74.2%, and Topo I expression in 59.1%, respectively. High expression of Topo I associated with lower response rate (RR) (96.7% in low group vs 78.4% in high group, p=0.029) and shorter progression-free survival (PFS) (65W vs 39W, p=0.040) but did not correlate with overall survival (OS). Phosphorylation of Met protein did not correlate with RR, PFS or OS. Interestingly, intensity of p-Met significantly correlated with Topo I expression (p=0.048). High expression of c-Met protein did not associated with RR or PFS but significantly associated with shorter OS (high 53W, low 95W, p=0.018). Multivariate analysis which included c-Met, stage, PS, and age resulted that c-Met was an independent prognostic factor for OS of pts with SCLC (HR; 2.144, 95% confidence interval 1.162-3.956, p=0.015). Conclusions: This study suggested c-Met high expression was an independent prognostic factor, and Topo I was up-regulated by Met in SCLC.
