[Expression of c-erb B-2 concoprotein in salivary adenoid cystic carcinoma]

: OBJECTIVE:In order to analyze the correlation between immunohistochemical expressin for c-erb B-2 oncoprotein and salivary adenoid cystic carcinoma (ACC). METHODS: 25 cases of ACC and two ACC cell strain was studied immunohistochemically using a monoclone antibody against c-erb B-2 oncoprotein. RESULTS: No positive results were obtained in any cell strain,but the invasive breast cancer expressed strong positive. CONCLUSION: It demonstrated that c-erb B-2 expression can not be used as a predictive marker for prognosis of ACC.
