Title | Optimal irradiation dosis in strontium brachytherapy in uveal melanoma |
Abstract Nr. | 2081 |
Purpose | To determine the best irradiation dosis for strontium brachytherapy in uveal melanoma. To investigate whether the dosis is best calculated as top dosis or base dosis. |
Methods | Review of 135 patients with uveal melanoma, treated with strontium brachytherapy. Different parameters, including age, tumor height, tumor diameter, tumor recurrence, irradiation dosis on the top and base, location of the tumor and ultrasound characteristics were categorised. |
Results | Mean age was 64 years at the time of the treatment, mean diameter 9 mm and mean height 4 mm. COMS classification defined 44 tumors as small and 87 as medium sized tumors. No local recurrence occured at a top dosis of 75 Gy. |
Conclusion | The best irradiation dosis for strontium brachytherapy in uveal melanoma is 75 Gy. The dosis is best calculated as top dosis. |
