This study compares the pattern of metastases in 228 patients with initial stage I and 635 patients with initial stage II breast cancer. All these patients had recurrence within a median time of follow-up of 4.9 years (range 2.0-7.0 years). All patients were initially mastectomized, and staging was based on histopathological evaluation of mastectomy specimens. ⋯ The prognostic significance of the classification of patients with breast cancer according to stage does not seem to discriminate tumours with different biological properties with regard to the rate as well as the pattern of dissemination. Postmastectomy follow-up of patients with stage I and II disease should therefore, follow the same guide-lines. Since the anatomical distribution of metastases was the same in different periods after mastectomy, the screening for recurrent disease should not be directed towards any specific sites in certain periods after initial diagnosis.
