[Recurrence and regional metastasizing of breast cancer after surgical treatment].

Frequency and time of relapse and regional spreading following surgery were studied in 1516 cases of breast cancer. Recurrence was observed in 10.4% of patients whereas regional metastasis--in 10.7%. Risk of relapse was found to depend upon stage and pattern of tumor rather than type of mastectomy. Mastectomy after Patey proved no inferior to that after Halsted for early breast cancer.
