Discovery of Key Candidate Protein Biomarkers in Early-Stage Nonsmall Cell Lung Carcinoma through Quantitative Proteomics.

Difficulties in early-stage diagnosis are among the factors contributing to the high mortality of nonsmall cell lung carcinoma (NSCLC) patients. Unfortunately, diagnostic biomarkers are currently lacking, limiting options in the clinic. To discover proteins that have potential for biomarker applications, we performed an in-depth quantitative proteomic analysis on a cohort of Filipino early-stage NSCLC lung adenocarcinoma (LUAD) patients.
