- W3131774752 abstract "OBJECTIVE: To determine the diagnostic accuracy of salivary MMP1 as non-invasive diagnostic biomarker of OSCC through conventional sandwich ELISA technique. Analytical cross-sectional study. METHODOLOGY: Individuals with clinical suspicion for OSCC (IWCS-OSCC) were included in the study after fulfilling selection criteria. Saliva samples were collected from IWCS-OSCC. To confirm OSCC, the patients were referred for biopsy. After definitive diagnosis on biopsy, patients were labeled OSCC positive or OSCC negative. The colorimetric sandwich-ELISA test was performed on saliva samples to measure the level of MMP1. Data was entered in Statistical Package for the Social Sciences (SPSS) -16 and levels of MMP1 were correlated with the biopsy status of patient (OSCC positive or OSCC negative). RESULTS: Our sample included twice as many males as females (2.1:1) and a wide age range of 22-77years with median age of 50yrs. Of all the IWCS-OSCC 85% were OSCC +ve and 15% were OSCC-ve. Diagnostic accuracy was measured as; Area under curve (AUC) = 0.623, Sensitivity (Sn) = 50%, Specificity (Sp)= 83.3%, Positive predictive value (PPV)= 94.4%, Negative predictive value (NPV)= 22.7% CONCLUSION: MMP1 as detected by conventional sandwich-ELISA technique is not proven as an accurate diagnostic biomarker of OSCC.
