OBJECTIVE: To estimate cytologic grade and correlate it with the other known prognostic factors, such as tumor differentiation, growth fraction, estrogen receptor status and nodal status. STUDY DESIGN: Fine needle aspirates from 104 invasive ductal carcinomas were stained by the Papanicolaou method and examined for necrosis, cellular size, nuclear/cytoplasmic ratio, nuclear pleomorphism, nucleoli, chromatin granularity and density of chromatin. We established a semiquantitative scoring system based on the above features and correlated cytologic findings with clinicopathologic variables. RESULTS: Histologic grade correlated positively with cytologic grade and negatively with estrogen receptor positivity. Moreover, high cytologic grade was associated with nodal metastasis and proliferative index labeling by MIB-1. CONCLUSION: This study showed that our grading system for breast cancer on fine needle aspiration cytology is feasible on a routine diagnostic basis. Cytologic grading can provide more information than usual on tumor biologic behavior.
