title: Neutron brachytherapy in the treatment of melanoma.
abstract: OBJECTIVE
  The use of Cf-252 for treatment of cutaneous malignant melanoma is presented.
  
  
  METHODS
  From 1975 to 1992, plaque Cf-252 applicator neutron brachytherapy was performed in nine patients with skin malignant melanoma of head and neck or chest wall. Neutron brachytherapy alone was applied in six patients; two patients received neutron brachytherapy before and one after photon teletherapy. Tumor neutron brachytherapy doses ranged from 3.9-11.5 Gy. Four patients underwent surgical resection of the primary tumor and in six cases, regional lymph node dissection was done.
  
  
  RESULTS
  The patients survival times ranged from 3 months to 12 years; 2-year survival was 50% and 30% of the patients lived 3 years. The mean survival time was 39 months. All but 1 patients died because of distant metastases. Local tumor control was achieved in all cases.
  
  
  CONCLUSIONS
  The clinical study shows the relative sensitivity of melanoma to the neutron irradiation and offer new possibilities in Cf-252 brachytherapy.
