Background and Objective: This study aimed to assess the immunohistochemical expression of stromal CD10 in invasive breast carcinoma and determine its relationship with some clinicopathological parameters.

Methods: A cross-sectional study was conducted on 91 female breast cancer cases collected from the archive of pathology department in Rizgary Teaching Hospital and some private labs during the period from January 2012 to August 2015. CD10 expression was detected by immunohistochemistry using labeled polymer and enhanced polymer systems (Dako EnVision™ Flex) Dakoprotocol. The scoring was based on the intensity and percentage of the stained stromal cells. Then CD10 immunoexpression was correlated with the age of patients, tumor size, histopathological types, tumor grade, lymphovascular invasion, lymph node status, and tumor stage.

Results: Stromal CD10 expression was observed in 70.4% of the cases. A statistically significant positive correlation was seen between stromal CD10 and the tumor subtype (P = 0.02), tumor grade (P = 0.025), lymphovascular invasion (P = 0.002), and lymph node status (P = 0.047), however, no statistically significant association was identified between stromal CD10 expression and age, tumor size and tumor stage.

Conclusion: Stromal CD10 is expressed in the majority of cases of invasive breast carcinoma and concerning the positive correlations between stromal CD10 expression and tumor grade, lymphovascular invasion, and lymph node status suggest a strong effect of stromal CD10 expression on aggressive behavior of breast carcinoma.
