Between 1970 and 1986, 990 patients underwent excisional biopsy and radiation for clinical Stage I or II breast cancer. A limited axillary dissection (levels I and II) was performed in 914 of these patients. The median follow-up was 40 months from the initiation of radiation. Thirty-one patients developed a regional node failure as their first site of recurrence either with (12 patients) or without (19 patients) simultaneous distant metastases. The median interval to recurrence was 27 months (range 4-59). The 5-year actuarial rate for an isolated regional node recurrence (without simultaneous distant metastases) was 3%. The most common site for a regional node failure was the axilla (17 patients) followed by the supraclavicular nodes (13 patients). Salvage therapy was effective for an axillary +/- breast failure with 10/14 patients alive with no evidence of disease. Prognosis was related to the site of recurrence as well as the presence or absence of distant metastases. The 5-year actuarial survival from initial treatment for all patients with a regional node failure was 63% with a 3-year actuarial survival of 57% from diagnosis of recurrence. Regional node failure was related to the number of axillary nodes removed at the time of dissection and patient age.
