    Atypical ductal hyperplasia in men with gynecomastia: what is their breast cancer risk?

    Purpose Atypical ductal hyperplasia (ADH) significantly increases the risk of breast cancer in women. However, little is known about the implications of ADH in men. Methods Review of 932 males with breast pathology was performed to identify cases of ADH. Patients were excluded if ADH was upgraded to cancer on excision, or if they had contralateral breast cancer. Cases were reviewed to determine whether any male with ADH developed breast cancer. Results Nineteen males were diagnosed with ADH from June 2003 to September 2018. All had gynecomastia. Surgical procedure was mastectomy in 8 patients and excision/reduction in 11. One patient had their nipple areola complex removed, and 1 required a free nipple graft. Median patient age at ADH diagnosis was 25 years (range 18–72 years). Of the 14 patients with bilateral gynecomastia, 10 had bilateral ADH and 4 had unilateral. Five cases of ADH were described as severe, bordering on ductal carcinoma in situ. No patient reported a family history of breast cancer. No patient took tamoxifen. At a mean follow-up of 75 months (range 4–185 months), no patient developed breast cancer. Conclusion Our study is the first to provide follow-up information for males with ADH. With 6 years of mean follow-up, no male in our series has developed breast cancer. This suggests that either ADH in men does not pose the same risk as ADH in women or that surgical excision of symptomatic gynecomastia in men effectively reduces the risk of breast cancer.

    Incidental atypical hyperplasia/LCIS in mammoplasty specimens and subsequent risk of breast cancer
    (2019) Armengol, Victor Diego ; Deng, Zhengyi; Tang, Rong; Coopey, Suzanne; Mazzola, Emanuele; Lanahan, Conor; Braun, Danielle; Yala, Adam; Barzilay, Regina; Li, Clara; Santus, Enrico; Colwell, Amy; Guidi, Anthony; Cetrulo, Curt; Garber, Judy Ellen; Smith, Barbara L.; King, Tari A.; Hughes, Kevin S.
    Background: Proliferative breast lesions with atypia (atypical hyperplasia and lobular carcinoma in-situ (LCIS)) increase the risk of breast cancer (BC). Most cases are diagnosed in the context of an abnormal mammogram. Little is known about BC risk for patients with these lesions who are asymptomatic. Mammoplasty specimens allow us to study breast tissue in asymptomatic healthy women. We previously published the rate of atypia in the largest reported mammoplasty cohort. The aim of this study is to examine the risk of BC in the atypia cohort. Methods: Breast pathology reports were retrospectively reviewed for evidence of atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH) or LCIS in bilateral reduction mammoplasty specimens from five institutions within a single healthcare system between 1990 to 2017. Patients with prior or concurrent BC or prior atypia were excluded. Data was extracted from electronic medical records using natural language processing and manual review to assess subsequent risk of BC. Results: From our mammoplasty cohort of 4771 patients, 295 patients were found to have atypia (6.2%) at baseline. 40 of these patients were lost to follow-up and excluded from the study. For the remaining 255 patients, 13 had severe ADH bordering on ductal carcinoma in situ, 52 had LCIS, 119 had ALH, and 71 had ADH at baseline. The median age at baseline was 52.1 (range 17.9 – 74.3). With a median follow-up of 7.7 years, of the 255 patients 9 patients developed BC (8 invasive carcinomas, 1 ductal carcinoma in situ). 81.3% of the cohort did not receive chemoprevention. Only one patient out of the nine who developed BC received chemoprevention. The risk of developing BC among women with atypia at baseline was 0.5%, 2.9% and 4.1%, at 3, 5 and 10 years respectively. Conclusions: Patients with asymptomatic atypias found in reduction mammoplasty specimens appear to be at lower risk of developing BC than those diagnosed with atypia in the context of an abnormal mammogram. These results may provide guidance on how to manage this group of patients related to future screening and/or chemoprevention.
