Objective: We aimed to evaluate the effect of hormone receptor and immunohistochemistry data on the incidence of primary tumor type and lymph node positivity in breast cancer cases.
Method: Demographic, immunohistochemical data of 62 patients who were biopsied in the institute's interventional radiology clinic and long axis of primary tumor in USG were retrospectively evaluated.
Results: The age of the patients, cell type, c-erb B-2 score and axillary lymph node positivity were not significantly correlated with the assessed data, whereas the long axis of primary tumor, estrogen and progesterone receptor severity and prevalence, KI 67 proliferation index affected lymph node involvement ratio.
Conclusion: Evaluation of lymph node involvement with second-line detailed USG before the operation, especially in malignant tumors refer to surgical or interventional radiology departments with negative, high KI 67 PI and C-erb B-2 values in estrogen and progesterone receptors, and the presence of recent axillary USG examination of the cases for breast biopsy regardless of the results, will provide important contribution in the diagnosis and treatment stages.
Key words: Breast cancer, hormone receptors, immunohistochemical data, axillary lymph node
