Abstract:
Twenty-six patients with mucosal malignant melanoma of the upper respiratory tract and of the oral cavity were seen at the oncologic departments of eastern Denmark from 1955 to 1989. There were 17 males and nine females with an average age of 65 years. Primary symptoms lasted from one to 24 months and depended on localization of tumor. Five patients had lymph node metastases at the time of diagnosis; one also had distant metastases. Ten patients had surgery as primary treatment, 10 had combined surgery and radiotherapy and six had radiotherapy. Complete remission after primary treatment was seen in 22 cases (85%) and lasted from three to 94 months. Seventeen patients had recurrence, six of these had recurrence twice or three times. The five-year crude survival was 35% and only one patient (4%) lived more than 10 years. Recurrence-free survival among the 22 patients with initially complete response was 14%.
