A new method for predicting survival in stage I non-small cell lung cancer patients: nomogram based on macrophage immunoscore, TNM stage and lymphocyte-to-monocyte ratio.

ABSTRACT:

Background

The prognosis of patients with stage I non-small cell lung cancer (NSCLC) is often uncertain. This study aims to investigate a new prognostic tool to classify stage I NSCLC patients more accurately.

Methods

CD68 and CD163 macrophages were quantified by immunohistochemical analyses of the center of the tumor and the invasive margin of the 339 tumors, which were used to construct the macrophage immunoscore (MI). Cox proportional hazards models determined the effects of multiple factors on disease-free survival (DFS) and overall survival (OS). One nomogram was developed to predict DFS and OS of stage I patients.

Results

The multivariate Cox analysis identified MI (P<0.001), lymphocyte-to-monocyte ratio (LMR, P=0.006), and TNM stage (P=0.046) as independent pro
