Abstract

The present study aimed to clarify the association between macrophages, tumor neo‑vessels and programmed cell death‑ligand 1 (PD‑L1) in the tumor microenvironment and the clinicopathological features of patients with non‑small cell lung cancer (NSCLC), and to explore the prognostic factors of stromal features in NSCLC. To determine this, tissue microarrays containing samples of 92 patients with NSCLC were studied using immunohistochemistry and immunofluorescence. The quantitative data demonstrated that in tumor islets, the number of CD68+ and CD206+ tumor‑associated macrophages (TAMs) was 8‑348 (median, 131) and 2‑220 (median, 52), respectively (P<0.001). In tumor stroma, the number of CD68+ and CD206+ TAMs was 23‑412 (median, 169) and 7‑358 (median, 81), respectively (P<0.001). The number of CD68+ TAMs in each location of the tumor islets and tumor stroma was significantly higher than that of CD206+ TAMs, and they were significantly correlated (P<0.0001). The quantitative density of CD105 and PD‑L1 in tumor tissues was 19‑368 (median, 156) and 9‑493 (median, 103), respectively. Survival analysis revealed that a high density of CD68+ TAMs in tumor stroma and islets and a high density of CD206+ TAMs and PD‑L1 in tumor stroma were associated with worse prognosis (both P<0.05). Collectively, the survival analysis demonstrated that the high‑density group was related to a worse prognosis regardless of combined neo‑vessels and PD‑L1 expression with the CD68+ TAMs in tumor islets and stroma, or CD206+ TAMs in tumor islets and stroma. To the best of our knowledge, the present study was the first to provide a multi‑component combined prognostic survival analysis of different types of macrophages in different regions with tumor neo‑vessels and PD‑L1, which demonstrated the importance of macrophages in tumor stroma.
