title: [Treatment modalities for conjunctival melanoma].
abstract: BACKGROUND
  Because of high local recurrence rates after excision of conjunctival melanoma adjuvant local chemotherapy employing mitomycin C (MMC) or irradiation is recommended. Brachytherapy is possible with ruthenium-106-plaques ((106)Ru) or with the strontium-90-plaques ((90)Sr).
  
  
  METHODS
  Fifty-six patients received an excision and adjuvant radiotherapy of conjunctival melanoma between 1992 and 2007. The mean follow-up was 42 months (12 - 151 months). Mean age was 62 (28- 86) years. As an adjuvant radiotherapy 15 patients received X-ray irradiation, 12 patients received (106)Ru-brachytherapy, 4 patients received proton beam therapy and 16 patients with conjunctival melanoma were treated with adjuvant strontium-90 brachytherapy after tumour excision. Four patients received proton beam irradiation and in 13 patients an exenteratio was performed.
  
  
  RESULTS
  Twelve patients (21 %) developed tumour recurrences in or adjacent to the irradiated area. Thirteen patients (22 %) showed a recurrence distant from the primary site. Ten patients (18 %) developed systemic metastasis during follow-up. Seven patients (46 %) had no recurrence during the follow-up. Three patients (20 %) had a recurrence in the treated or adjacent areas. Eight patients (53 %) developed new tumours in non-treated areas.
  
  
  CONCLUSIONS
  Adjuvant radiotherapy allows an acceptable local tumour control rate after excision of conjunctival melanoma. No obvious differences regarding tumour control or systemic metastasis could be seen between the different modes of radiotherapy used.
