Clinical Indications for Mammography in Men and Correlation With Breast Cancer.

PURPOSE

The purpose of this study is to examine the correlation between presenting clinical symptoms and imaging findings in men with breast cancer.

METHOD AND MATERIALS

Four hundred twenty-nine male patients who presented for mammography at one institution between January 2004 and December 2014 were retrospectively evaluated. Of the 429 patients, 291 presented with clinical symptoms for diagnostic mammography. The presenting clinical symptoms in 291 patients were recorded and correlated with imaging and histopathologic findings.

RESULTS

Two hundred ninety-one male patients were included. Some presented with multiple symptoms, for a total of 318 clinical symptoms. One hundred and ninety (65%) men presented with palpable abnormalities, 44 (15%) with nonfocal pain, 31 (11%) with breast swelling, 14 (5%) with breast enlargement, 13 (4%) with focal pain, 7 (2%) with skin changes, 6 (2%) with nipple discharge/changes and 13 (4%) with other symptoms (itching, throbbing and breast heaviness). A total of 290 patients underwent mammography and 176 underwent sonography. Forty-one malignancies were diagnosed, of which 24 (59%) were invasive ductal carcinoma. Nipple changes/discharge had a 100% positive predictive value for malignancy while breast pain showed a 0% positive predictive value. Fifty-two patients showed either a mass or a focal asymmetry on mammography, of which 38 (73%) were malignant. Three patients (1%) without a mass or focal asymmetry were diagnosed with malignancy.

CONCLUSION

Correlating clinical symptoms and imaging findings can help with timely and accurate diagnosis of breast cancer in men. Nipple discharge/changes and skin changes with palpable abnormalities and mammographic findings of masses and focal asymmetries were associated with breast cancer. Pain, breast enlargement, and breast swelling were unlikely to be associated with malignancy.
