Stromal Expression of CD10 in Breast Carcinoma and Its Association with Known Prognostic Factors-A Tissue...

Area of Science:

• Oncology
• Cancer Biology
• Immunohistochemistry

Background:

• Breast cancer progression involves complex interactions between epithelial cells and the tumor stroma.
• CD10, a matrix metalloproteinase, influences cell adhesion, migration, and tumor invasion.
• Understanding stromal factors like CD10 is crucial for identifying therapeutic targets.

Purpose of the Study:

• To determine the frequency of stromal CD10 expression in breast carcinomas.
• To evaluate the prognostic significance of stromal CD10 by correlating it with established prognostic factors.

Main Methods:

• Analysis of 62 breast carcinoma cases using H&E staining and immunohistochemistry (IHC).
• Evaluation of stromal CD10 expression alongside estrogen receptor (ER), progesterone receptor (PR), and HER2/neu.
• Correlation of CD10 scores with tumor size, grade, lymph node status, necrosis, lymphovascular invasion, and molecular subtypes.

Main Results:

• Stromal CD10 expression was observed in 82.3% of cases.
• Significant associations were found between CD10 expression and increased tumor size, higher tumor grade, lymph node metastasis, necrosis, and lymphovascular invasion.
• CD10 expression correlated with ER negativity, PR negativity, HER2 positivity, triple-negative status, and poorer prognostic groups.

Conclusions:

• Stromal CD10 is a frequent finding in breast cancer and is associated with adverse prognostic factors.
• CD10 demonstrates potential as an independent prognostic stromal marker in breast carcinomas.
• These findings may inform the development of novel therapeutic strategies targeting CD10.
