Correlation of Cyfra 21-1 levels in saliva and serum with CK19 mRNA expression in oral squamous cell carcinoma
Abstract
Oral squamous cell carcinoma (OSCC) accounts for 90 % of malignant lesions of oral cavity. The study assessed the potential of Cyfra 21-1 as a tumor marker in OSCC. The study included 50 patients of OSCC to evaluate levels of Cyfra 21-1 in serum and saliva by electrochemiluminescent immunoassay (ECLIA) and CK19 messenger RNA (mRNA) expression in tissue by florescent quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR) along with healthy individuals as control. The salivary and serum Cyfra 21-1 levels in patients of OSCC were significantly higher compared to controls (p value < 0.01). There was a 2.75-fold increase in CK19 mRNA expression in OSCC cases compared to controls. A significant positive correlation was found between serum and salivary Cyfra 21-1, serum Cyfra 21-1, and CK19 mRNA expression and between salivary Cyfra 21-1 and CK19 mRNA expression. Among these, correlation between serum and salivary Cyfra 21-1 was highly significant. Salivary and serum Cyfra 21-1 showed significantly elevated levels in grade II OSCC compared to grade I histopathologically. Elevated levels of salivary Cyfra 21-1 were associated with recurrence in OSCC patients. Reverse operating curve constructed using 3 ng/ml as...Continue Reading
