Advances have been made in systemic as well as locoregional treatment of primary breast cancer. Evidence, based established therapeutic strategies, for isolated locoregional lymph node recurrence is not yet sufficient. In this series, we focused especially on isolated axillary lymph node recurrence (AR) and supraclavicular lymph node recurrence (SR) in patients receiving systemic and/or radiation therapy combined with surgery. Disease free survival (DFS) in patients with AR ranged from 20 to 36 months. From 69% to 77% of all patients underwent surgical excision. The 5-year overall survival (OS) ranged from 39% to 46%. Positive lymph node metastases of primary cancer, size of the primary tumor, and R0 resection were associated with good outcomes. Longer DFS is associated with good outcomes. Limited SR data showed DFS to range from 25–27%. Median progression free survival (PFS) was 18 months, 5-year OS rates were 24–42%, and 5-year OS were 29–34 months. Combination therapy was an independent factor associated with better PFS as compared to local therapy only. Salvage treatment and grade of the primary tumor significantly were associated with OS on multivariate analysis. Available data, retrospective and not randomized, showed therapy combining systemic treatments and/or radiotherapy with surgery might contribute to good local control, better PFS, and longer OS.
