Robinson cytologic grading in invasive ductal carcinoma of the breast: correlation with E-cadherin and alpha-, beta- and gamma-catenin expression and regional lymph node metastasis.

Objective: To correlate the cytologic grade of breast carcinoma with the expression of E-cadherin/catenin system molecules and the presence of metastasis in regional lymph nodes.

Study Design: Aspirate smears were examined together with histologic sections from the corresponding neoplasms taken from 100 patients with invasive ductal carcinoma. In 50 cases, > or = 1 metastatic nodes were identified.

Robinson cytologic grading of invasive ductal breast carcinoma: correlation with histologic grading and regional lymph node metastasis.

Objective: To evaluate the importance of cytologic grading of breast carcinoma and its association with histologic grading and the existence of axillary lymph node metastasis.

Study Design: Aspirates and surgical samples from 100 patients with invasive ductal breast carcinoma not otherwise specified were studied. In 50 patients, > or = 1 metastatic nodes were identified.
