Radiation monotherapy as regional treatment for lymph node-positive merkel cell carcinoma
2010
BACKGROUND: Merkel cell carcinoma (MCC) is an aggressive cutaneous malignancy with a high risk of lymph node involvement. To the authors’ knowledge, few data have been published to date regarding the optimal regional therapy for lymph node-positive patients. This cohort study was performed to analyze the outcomes of patients with lymph node-positive MCC treated with lymph node irradiation as definitive therapy compared with completion lymphadenectomy (CLND). METHODS: Fifty patients with lymph node involvement of MCC at presentation and adequate follow-up data were included in this analysis. Forty-three of these patients were enrolled and followed prospectively. Twenty-six patients presented with microscopic lymph node disease, and 24 patients presented with palpable lymph node involvement. RESULTS: Regional control for patients with microscopically involved lymph nodes
