Lymph node metastasis in breast carcinoma: clinicopathological correlations in 3747 patients.

Background: Histological axillary node involvement (ANI) evaluated by axillary dissection remains the most accurate predictive factor for patients with invasive breast cancer. Axillary node involvement implies the necessity of systemic adjuvant treatment and locoregional irradiation.

Aim Of The Study: Is to detect the relative frequency of node positivity in relation to histopathology through studying a large mastectomy series.
