BACKGROUND: The purpose of the current study was to determine the outcomes of patients with previously untreated Merkel cell carcinoma of the skin who were treated with curative intent. METHODS: Between October 1984 and January 2002, 34 patients were treated with radiotherapy alone (2 patients) or combined with surgery (32 patients). Nine patients received adjuvant chemotherapy. Patients had follow-up for a median of 3.0 years (range, 0.3 to 18.5 yrs). Follow-up on living patients ranged from 2.2 to 18.5 years (median, 7.1 yrs). RESULTS: The 5-year outcomes were as follows: local control, 94%, locoregional control, 80%; freedom from distant metastases, 60%; cause-specific survival, 52%; and survival, 37%. No patient experienced a severe complication. CONCLUSIONS: Patients treated aggressively with surgery and locoregional radiotherapy have about a 50% chance of cure. Limited data suggest that definitive radiotherapy alone or after incomplete macroscopic resection may control locoregional disease in a significant subset of patients. The dominant site of failure was distant. Copyright 2005 American Cancer Society
