RESUMEN
OBJECTIVE: To study the feasibility of modified urinary nucleosides metabolic profiling on lung cancer diagnoses. METHODS: The modified urinary nucleosides metabolic profiling from 42 normal adults and 80 patients with lung cancer were determined by a coupled-column high performance liquid chromatography system. Partial least squares-discriminant analysis (PLS-DA) models were used to class differentiation between the lung cancer patients and controls and to discover potential biomarkers. RESULT: The PLS-DA model results showed that there was a clear differentiation between normal adults and lung cancers patients, with the value of prediction (Q2) equals to 0.744. CONCLUSION: Modified urinary nucleosides metabolic profiling method is useful for lung cancer diagnoses.
