Distinct cellular immune profiles in lung adenocarcinoma manifesting as pure ground glass opacity versus solid nodules.

ABSTRACT:

Introduction

Ground glass opacity featured lung adenocarcinomas (GGO-LUAD) display more indolent biological behavior than solid nodule featured lung adenocarcinomas (SN-LUAD) and have an excellent prognosis. However, the cellular immune characteristics of GGO-LUAD remain poorly understood.

Methods

Immunohistochemistry technique was performed to stain related immune markers (CD8, CD103, CD20, CD138, CD4, FOXP3, CD68, CD163, PD-1 and PD-L1) and TGF-β from 15 patients with pure GGO-LUAD and 15 patients with SN-LUAD tissue sections (Paired cohort), and then, the related markers with significant differences were verified on 10 patients (Verified cohort) with both pure GGO-LUAD and SN-LUAD. For localization analysis of CD68 + tumor-associated macrophages (TAMs) and FOXP3 + Terg ce
