Differences in tumor angiogenesis and related factors between lung adenocarcinomas manifesting as pure ground glass opacity and solid nodules.

ABSTRACT:

Introduction

The prognosis of ground glass opacity featured lung adenocarcinomas (GGO-LUAD) is significantly better than that of solid nodule featured lung adenocarcinomas (SN-LUAD), but the specific reasons behind their indolent tumor behavior are still unclear. The purpose of this study is to investigate their differences in intratumoral microvessels, related angiogenic factors and important stromal cells.

Methods

Thirty patients (15 paired patients only with GGO or SN) diagnosed with pathological stage 0-I lung adenocarcinoma who underwent surgical treatment were included into this study. Immunohistochemistry was performed to stain the blood vessel markers (CD31, CD34 and CD105), LYVE-1, the cancer-associated fibroblasts (CAFs) markers (α-SMA and S100A4), TGF-β and HIF-1α
