Detection of both serum MMP1 and P53 autoantibody for the diagnosis of esophageal squamous cell carcinoma
OBJECTIVE:To evaluate diagnostic values from the combined detection of serum MMP1 and P53 autoantibody in patients with esophageal squamous cell carcinoma(ESCC).METHODS:The study included 93 ESCC patients hospitalized in the Cancer hospital of Shantou University Medical College and 90 physical examination subjects as normal controls.Serum levels of MMP1 and P53 autoantibodies were measured by enzyme-linked immunosorbent assay(ELISA).The diagnostic value was evaluated using the receiver operating characteristic(ROC)curve.RESULTS:The serum levels of MMP1 and P53 autoantibodies of ESCC patients were higher than those in normal controls(P＜0.01).ROC curves showed that the area under curve(AUC)of MMP1 in ESCC diagnosis was 0.700(95％CI:0.624-0.776).When the optimum diagnostic cutoff was 7.248 ng/mL,the sensitivity was 52.7％,and the specificity was 83.3％.Measurement of P53 autoantibodies demonstrated an AUC of 0.713(95％CI:0.638-0.788),with the diagnostic cutoff of 0.080 and a sensitivity/specificity of 49.5％/83.3％.The combination of MMP1 and P53 autoantibodies yielded an AUC of 0.787(95％CI:0.720-0.854),a sensitivity of 66.7％and a specificity of 83.3％.In early-stage ESCC,combined detection of MMP1 and P53 autoantibodies provided good diagnostic power(AAUC=0.760;95％CI:0.663-0.857),with 66.7％sensitivity and 83.3％specificity.CONCLUSION:Serum MMP1 and P53 autoantibody were both over-expressed in ESCC patients.The use of both biomarkers was helpful in making early diagnosis of ESCC.
