Retrospective analysis of inflammatory biomarkers and prognosis in non-small cell lung cancer without adenocarcinoma in situ

TL;DR

This study examines how inflammatory biomarkers affect survival in non-small cell lung cancer patients without a specific early-stage subtype.

Contribution

The study evaluates inflammatory biomarkers in NSCLC while excluding Adenocarcinoma In Situ to avoid bias.

Findings

Higher inflammatory biomarker levels correlated with poorer survival in NSCLC patients.

Multivariate analysis showed traditional factors like age and tumor stage were better long-term predictors than biomarkers.

Abstract

Inflammatory biomarkers have shown prognostic value in Non-Small Cell Lung Cancer (NSCLC), but the inclusion of Adenocarcinoma In Situ (AIS) cases in previous studies may introduce bias. This study aims to evaluate the prognostic significance of inflammatory biomarkers in NSCLC while excluding AIS.

This study included patients who received surgery for lung carcinoma from August 2016 and August 2019. We collected demographic, clinical, laboratory, and outcome information. Inflammatory biomarkers were analyzed using receiver operating characteristic (ROC) curves, Kaplan-Meier survival analysis, and Cox regression to assess their prognostic value.

Higher levels of inflammatory biomarkers correlated with poorer survival, with significant differences in overall survival (OS) between high- and low-expression groups. However, multivariate Cox regression identified age, tumor stage, and differentiation as independent prognostic factors, while biomarkers were not independently predictive.

Inflammatory biomarkers have short-term prognostic value in invasive NSCLC, but traditional clinical and pathological factors remain key for long-term outcomes.
