The Stromal Expression of CD-10 in Breast Carcinoma and its Association with Estrogen, Progesterone receptors, Her2Neu and Tumor Grade
Introduction: In previous studies, role of stromal component in epithelial malignancies has been highlighted. CD10 is a member of metalloproteinase family that breaks down the protein components of extracellular matrix and epithelial tissue remodeling thus playing an important role in carcinogenesis and metastasis.
To evaluate CD 10 expression in breast carcinoma and assess its association with grade of the tumor, ER, PR and Her 2 Neu status.
Methodology: The study was carried in Federal Government Polyclinic Hospital (FGPH) and Pakistan Institute of Medical Sciences (PIMS), Islamabadԁ. Immunohistochemical panel of CD 10, ER, PR and Her 2 was applied to 171 cases of invasive breast carcinoma. The association of CD 10 anԁ ER/PR status was evaluated.
Results: Among 171 cases of breast carcinoma, 77.8% cases were CD-10 positive. A total of 65.5% of ER negative cases expressed strongly positive CD-10 in the stroma as compared to 37.2% of ER positive cases (P=0.001). In 64.4% of PR negative cases expressed strong positivity of CD-10 in the stroma compareԁ with 37.5% (42/112) PR positive cases (P=0.001). The association of CD-10 with HER-2-NEU was not significant (P=0.749). Association of high-grade tumor with CD 10 was not statistically significant (P=0.258).
Conclusion: It was observed that CD10 expression is associated with negative ER, PR status and with higher grades of the tumors, showing its prognostic significance.
