Abstract

Aims: Pleomorphic adenoma (PA) is the most common salivary gland tumour with a tendency to recur (RPA) and a risk of malignant transformation. Mucin 1 (MUC-1) plays a role in the progression of many tumours and may be a marker to predict RPA. The aim of this study was to evaluate MUC-1 expression in different phases of the adenoma to carcinoma sequence. Methods and results: Twenty-one cases of PA, 18 cases of RPA, three cases of RPA with focal transformation (TRPA) and 11 cases of carcinoma ex-pleomorphic adenoma (CXPA) were analysed immunohistochemically for MUC1 expression using an antibody to MUC1/DF3. MUC1 reactivity in RPA was stronger than that observed in PA and, in all the different carcinoma groups, MUC-1 expression was significantly higher in carcinoma than in RPA and PA. Conclusion: This study has confirmed that MUC-1 is related to the recurrence of PA and that this molecule is associated with malignant transformation of PA with carcinoma cells overexpressing MUC-1.
