Abstract:
The axillary lymph node status of patients with newly diagnosed breast cancer remains the most important prognostic information available at the moment. However, only a minority of patients presents with such node metastases at diagnoses. We reviewed our database and studied 500 consecutive patients with early breast cancer, and found that age inferior to 50 years, high grade, diameter superior to 1 cm, elevated Ki-67, and expression of oncogene p-53 are all factors associated with lymph node metastases.
