Abstract |
Objectives :The aim of this study was to investigate immunohistochemical expression of CK7, CK19, CK20, SMA and Ki-67 in Adenoid cystic carcinoma(ACC) of the Head and Neck. Material and Methods :Sixteen patients who were treated in Chungbuk National University Hospital from 1992 to 2004, were included in this study. Ten ACCs, 3 MECs, 1 Salivary duct carcinoma, 1 Adenocarcinoma(NOS), and 1 cacinoma ex pleomorphic adenoma were analyzed immunohistochemically for CK7, CK19, CK20, SMA, and Ki-67. Results :CK7 was expressed in 100% of the adenoid cystic carcinoma and 75% of the other tumors. CK19 was expressed in 75% of the adenoid cystic carcinoma and 100% of the other tumors. CK20 was not expressed in all tumors. SMA was expressed in 88.9% of the adenoid cystic carcinoma and not expressed in the other tumors. Ki-67 was expressed in low level in the adenoid cystic carcinoma. Conclusion :The Ki-67 index could explain the natural course of tumor. Immunohistochemistry of CK7, CK19, CK20, SMA and Ki-67 expression in Adenoid cystic carcinoma may provide useful information to diagnosis. |
