Cytohistomorphological grading of breast carcinoma with special reference to apoptotic rates and lymph node metastasis.
To analyze the significance of comparative evaluation of cytohistomorphological grading of infiltrating ductal carcinoma with specific reference to lymphnode metastasis status and apoptotic index. 50 patients who underwent FNAC and mastectomy for infiltrating ductal carcinoma were included in the study. Concordance between cytological and histological grades was calculated. Cytological smears were also evaluated for apoptotic rates and lymph node metastasis and then compared with the histological grades using regression analysis. Histological and cytological grades were comparable and statistically significant difference was found in the lymphnode metastasis rate and apoptotic index in the three cytological grades of the tumor. Moreover, by considering the apoptotic rates, the sensitivity of cytological grading significantly rose in relation to histological grade. With histological grade taken as the standard, cytology was found to be comparable but less sensitive for grading infiltrating ductal carcinoma. However, by considering lymphnode status and apoptotic rates as calculated on cytology, the sensitivity of cytological grading rose significantly in relation to histological grade. Therefore, apoptotic index incorporated with cytological grade may provide relevant information on the aggressiveness of invasive ductal carcinoma of breast and could be a useful parameter to take into consideration when selecting neo-adjuvant therapy.
