Expression of vascular endothelial growth factor, CD10, and factor 8 in phyllodes tumor: A 5-year study of 38 cases

Introduction: Phyllodes tumor is a group of biphasic fibroepithelial tumors of the breast, graded as benign, borderline, and malignant. The grading of breast phyllodes remains a challenging task for the pathologists as the prognosis, and further treatment depends on it. In this study, an effort has been made to grade phyllodes tumor on the basis of immunohistochemistry. Aims and Objectives: Vascular endothelial growth factor, CD10, and factor 8 have been used as immunohistochemical markers for grading. Results and Conclusion: We have found a significant correlation between the expression of these markers and grading of phyllodes tumor. Positive correlation was also found amongst expression of all three markers. To conclude, increased expression of these markers with increasing grade can aid in diagnosis and guide treatment.
