Proliferative Lesions Found at Reduction Mammaplasty: Incidence and Implications in 995 Breast Reductions

Abstract

Background: Reduction mammaplasty relieves symptomatic macromastia. Pathologic specimens occasionally reveal unsuspected proliferative lesions or carcinoma. Few studies examine the incidence, risk factors, and outcomes in this population.

Methods: A retrospective review was performed between 2000 and 2012. The pathologic condition was categorized as benign, proliferative, or cancer.

Results: Five hundred seventy-two patients underwent 995 reduction mammaplasties. Cancer was detected in 23 specimens (2.3 percent) and proliferative lesions were detected in 137 (13.8 percent). Compared with patients with benign pathologic findings, patients with proliferative lesions or cancer were older (p < 0.001), had greater body mass index (p = 0.003), had increased unilateral procedures (p < 0.001), and more had history of cancer (p < 0.001). On multivariable regression analysis, age (OR, 1.058; 95 percent CI, 1.040 to 1.077; p < 0.001) and prior breast cancer (OR, 2.070; 95 percent CI, 1.328 to 3.227, p = 0.001) were independent risk factors for proliferative lesions, and age significantly predicted cancer (OR, 1.054; 95 percent CI, 1.012 to 1.097; p = 0.010). Forty-one percent of patients with proliferative lesions and no history of cancer had a change in management. If there was a history of cancer, 54 percent had a change in management.

Conclusions: Proliferative lesions of the breast may be more common than previously reported. Age and a history of breast cancer increase the risk for proliferative lesions. All should be referred to oncology, as nearly half of these patients will have a change in management.

Clinical question/level of evidence: Risk, III.
