Abstract
The treatment for the patients with Paget disease of the breast is controversial. This review of its natural history, treatment approach, and clinical outcome will help to formulate treatment. Forty-one patients with a diagnosis of Paget disease of the breast were retrospectively reviewed at Providence Hospital & Medical Centers from 1980 to 1999. Ninety-eight percent of patients had underlying carcinoma (ductal carcinoma in situ and/or invasive ductal cancer). Patients with a palpable mass have a much higher incidence of invasive ductal cancer, positive lymph node, and a worse survival rate. The median length of follow-up was 42 months (range: 6--200 months). Twenty-seven percent of patients (11/41) had conservative operations, including 1 patient with a palpable mass; 10 patients with no palpable mass; and 3 patients with recurrence after conservative operation. Thirty-seven percent of patients received adjuvant therapy. Paget disease of the breast has very high incidence of underlying carcinoma (100% in a palpable mass, 96% in nonpalpable mass). Patients with a palpable mass have a worse survival than do patients with nonpalpable mass. Conservative operation should cautiously be selected even for patients with no palpable mass because of a higher recurrence rate.
