[Study of salivary metabonomics in patients with oral squamous cell carcinoma and leukoplakia]. | LitMetric
Purpose : The objective of this study was to detect and analyze the existence of differential metabolites from saliva of patients with oral squamous cell carcinoma(OSCC) by metabonomics method, and to evaluate its application value on clinical diagnosis or screening of OSCC.Methods : The collected saliva samples for OSCC patients, oral leukoplakiac(OLK) patients who were pathologically diagnosed and met the inclusion criteria were analyzed using metabonomics methods (GC-TOF-MS). The results were analyzed by principal component analysis and orthogonal partial least squares discriminant analysis using SIMCA software.Results : The metabolic profiles of OSCC, OLK and healthy control group showed significant differences (P<0.05). In total, 15 typical differential metabolites among the three groups were detected. Further study focusing on metabolic pathway revealed imbalance of protein, energy and lipid metabolism between OSCC and OLK patients. Abnormal tricarboxylic acid cycle was detected as well.Conclusions : Metabonomics methods is feasible for differential metabolites analysis,15 differential metabolites were detected in OSCC,OLK patients and healthy people. These findings will contribute to the early screening of oral squamous cell carcinoma.
