✦ Synopsis

In a retrospective study 143 patients with 155 axillary lymphadenectomies were observed with a maximum of 8 years of follow-up (mean 51.9 +/- 25.8 months). At the time of their lymphadenectomies, 39 patients had histologically negative nodes (stage I), 85 patients lymph-node metastases (stage II), 19 patients axillary node involvement and distant metastases (stage III). The estimated 5-year survival rates were 77.5% in stage I and 28.6% in stage II. Axillary recurrence after dissection of tumor-free lymph nodes rarely happened, but in stage II the probability of recurrence was as high as 30.7%. All axillary recurrences occurred in the first 20 months after lymphadenectomy. In a multivariate analysis (Cox model), the only prognostic factor of probability of recurrence in stage II was the development of regional in-transit cutaneous metastases (p = 0.048). Factors that did not affect the appearance of recurrent metastases in the node dissection field were: epidermal ulceration, vascular invasion, tumor thickness, degree of lymph-node involvement, age, sex, and adjuvant chemotherapy. Median survival after axillary recurrence following therapeutic lymph-node excision (5 months) was comparable with survival after lymphadenectomy in stage III (7 months). There was a high incidence (> 30%) of regional in-transit cutaneous metastases in both groups. Regardless of the poor prognosis, we found 15% axillary recurrences after lymph-node clearance in stage III.
