Abstract

CD10 is a cell surface zinc metalloprotease expressed through a variety of normal cell types, including lymphoid precursor cells, germinal center B lymphocytes, and some epithelial cells. Many studies showed that CD10 expression is associated with the tumor progression of a large variety of cancers, such as breast and colorectal carcinomas. The aim of this study was to investigate the expression of CD10 in nasopharyngeal carcinoma (NPC). The expression of CD10 was immunohistochemically examined in 47 paraffin embedded NPC biopsies from Tunisian patients compared with 16 reactional nasopharyngeal mucosas. A significant expression of CD10 was observed in stromal fusiform cells in 46.8% of NPC cases but was not in malignant and normal epithelial cells. There was no significant expression of CD10 in control group. The stromal expression of CD10 was more frequently detected in advanced clinical stage than early stage (56 vs 23%; p=0.04) and in patients older than 25 years than in patients under 25 years (56.2 vs 26.5%; p=0.05). Our study is the first in investigating CD10 expression in nasopharyngeal carcinoma and showed that CD10 expression by stromal cells in this malignancy play an important role in tumor progression, particularly in older patients.
