Neoplasm Recurrence, Local
Paget's Disease, Mammary
The incidence of distant metastases at presentation was lowest, and RFS was longest, for patients with T4d tumors not grossly involving the skin or posterior structures. Patients whose tumors grossly invaded both skin and posterior structures (T4c) or those with T4d tumors grossly invading either most frequently presented with distant metastases and had the shortest RFS.
