| Research Abstract |
The present study aims to identify a reliable marker for predicting the risk of invasion and metastasis in EMPD.To confirm MUC protein expressions, we analyzed 44 specimens from 38 primary EMPD cases by immunohistochemical staining. Labeling rates of tumor cells were scored by staining intensity on a four-tiered scale (- to 3+) to investigate the correlation between the expression score of these molecular markers and the type of EMPD lesion. Invasive lesions and metastatic lymph nodes tended to express MUC5AC significantly higher than in situ lesions (P<0.01). In conclusion, the degree of MUC5AC expression may correlate with the invasiveness and progression of EMPD, and may be a useful marker for identifying high-risk EMPD cases.
