NSE/Alb as a Prognostic Biomarker for Lung Cancer (NARPBLC)

A Prospective Cohort Study on NSE/Alb as a Prognostic Biomarker for Lung Cancer Patients in Multicenter

The incidence and mortality rate of lung cancer is the highest in the world. Current studies have found that tumor markers, inflammatory or nutritional indicators have a good predictive value for the prognosis of patients with non-small cell lung cancer (NSCLC). Neuron specific enolase (NSE) and serum albumin (Alb) are important indicators for monitoring tumor progression and nutritional status in lung cancer patients, respectively. Previous studies suggested that the higher the NSE, the worse prognosis of NSCLC patients, while the lower the Alb, the worse the prognosis of patients with malignant tumors. Through a retrospective study, the investigators found that NAR (NSE Alb Ratio) was higher and prognosis was poorer in patients undergoing NSCLC surgery. This is better than the previous assessment indicators PLR (platelet to lymphocyte ratio), NLR (neutrophil to lymphocyte ratio), AGR (albumin to globulin ratio), NAR can better assess prognosis. Therefore, on the basis of the previous retrospective analysis, the optimal NAR cut-off value was calculated according to ROC curve, and the value was grouped into multi-center prospective cohort study, and the relationship between NAR and other clinical indicators was studied by chi-square test. Univariate and multivariate analysis of Cox proportional hazard regression model was used to determine the prognostic factors. Finally, NSCLC patients were stratified according to tumor stage and pathological classification, and the differences of survival time between high NAR group and low NAR group were compared again under different stages and types, and the different stages of NAR in NSCLC patients were further analyzed. The clinical significance of typing. By exploring and validating the relationship between NAR and the prognosis of NSCLC patients, the investigators try to establish a new prognostic index. Obviously, it has important value for clinical application.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
high NAR; Neuron-Specific Enolase to Albumin Ratio is higher than 3.2×10-7	Diagnostic test: Neuron-Specific Enolase to Albumin Ratio; Previous studies have shown that inflammation and nutrition-related factors such as CRP/Alb (C-reactive protein-albumin ratio), PLR (platelet-to-lymphocyte ratio), NLR (neutrophil-to-lymphocyte ratio) can help to assess the prognosis of malignant tumors. This study is the first time to combine NSCLC tumor marker NSE and patient nutrition-related indicators Alb to predict the prognosis of patients, trying to find high sensitivity and specificity for NSCLC prognostic indicators to guide clinical work.
low NAR; Neuron-Specific Enolase to Albumin Ratio is lower than 3.2×10-7	Diagnostic test: Neuron-Specific Enolase to Albumin Ratio; Previous studies have shown that inflammation and nutrition-related factors such as CRP/Alb (C-reactive protein-albumin ratio), PLR (platelet-to-lymphocyte ratio), NLR (neutrophil-to-lymphocyte ratio) can help to assess the prognosis of malignant tumors.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall survival	The time from randomization to death due to any cause. The last follow-up time is usually calculated as the time of death for those who have been lost before death.	2 years.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Disease-free survival	Refers to the time from randomization to relapse or death due to disease progression. It is usually the end point after radical surgery. DFS is more difficult to record as an end point than OS because it requires careful follow-up and timely detection of disease recurrence. In this study, as an important prognostic indicator for patients undergoing NSCLC surgery.	2 years.
