Lymph node biopsy does not impair survival after therapeutic dissection for palpable melanoma metastases

BACKGROUND: To determine the effects of disrupting a nodal basin in patients with American Joint Committee on Cancer stage III melanoma with clinically palpable lymph nodes, we studied patients who underwent therapeutic lymph node dissection after excisional lymph node biopsy, after fine-needle aspiration (FNA) biopsy, or without a preoperative biopsy. METHODS: We performed a retrospective review of our patients with American Joint Committee on Cancer stage III melanoma who were treated between January 1972 and June 1995, using data acquired from our 8200-patient database. The study group included 670 patients with melanoma, with known primary tumors, who underwent therapeutic lymph node dissection for palpable nodal metastases diagnosed by open biopsy (227 patients), by FNA (66 patients), or by clinical observation without biopsy (377 patients). Regional node recurrence, 5-year disease-free survival, and overall survival rates were calculated. RESULTS: The same-basin regional node recurrence rates were similar for the three groups (open biopsy, 4.6%; FNA, 3.2%; no biopsy, 4.6%; P = .14). The 5-year disease-free survival rates were 36.8% for the open-biopsy group, 29.6% for the FNA group, and 28.9% for the no-biopsy group (P = .08); corresponding 5-year overall survival rates were 40.6%, 43.9%, and 36.1%, respectively (P = .18). Multivariate analysis failed to identify preoperative biopsy as a significant risk factor. Matched-pair analysis using age, gender, primary tumor site, Breslow thickness, and tumor burden showed no differences in the 5-year disease-free survival rates (33% for the open-biopsy group vs. 27% for the FNA and no-biopsy groups, P = .42) and the 5-year overall survival rates (41% vs. 35%, P = .32). CONCLUSIONS: For patients with melanoma with palpable regional adenopathy, histological confirmation of clinical suspicion with either FNA or excisional lymph node biopsy does not adversely affect survival or recurrence rates.
