Breast cancer is often evaluated using fine-needle aspiration cytology (FNAC), which is a simple and minimally invasive first-line diagnostic procedure. Among the various cytological grading methods, Robinson’s system is most commonly used because of its high reproducibility and strong prognostic significance.
Fifty confirmed cases of breast carcinoma were cytologically evaluated and correlated with histopathological findings in this retrospective study conducted in the Department of Pathology, B.J. Medical College and Civil Hospital, Ahmedabad. Cytological grading was performed on FNAC smears using Robinson’s method, while histological grading of tissue sections was done according to the modified Bloom-Richardson system. Overall concordance between the two grading systems was 60%.
Cytological grading of breast carcinoma using the Robinson system is a straightforward and reliable method that demonstrates a good correlation with histopathological grading. It offers valuable prognostic insight and plays a supportive role in guiding appropriate neoadjuvant treatment decisions.
