Abstract
OBJECTIVES
To conduct a clinicopathologic study of male breast carcinoma with Magee equation recurrence score (RS).
METHODS
Seventy-four cases of male invasive breast cancers (MBCs) were studied, including 63 hormone receptor (HR)-positive, 10 human epidermal growth factor receptor 2-positive, and one triple-negative breast cancers.
RESULTS
Among 63 HR-positive MBC patients, nine patients developed distal metastasis. Statistical analysis demonstrated distal metastasis was significantly associated with positive lymph node, high Nottingham grade, and increased Magee equation RS. All HR-positive MBCs were further stratified into two categories (low RS <18; intermediate/high RS ≥18). There was a significantly increased risk for distal metastasis in MBCs with intermediate/high Magee equation RS, but no increased risk for lymph node metastasis.
CONCLUSIONS
Our data suggest Magee equation RS may be useful to predict distal metastatic risk in MBC patients.
