[The proton radiotherapy of melanoma of the uvea. The technic, methodology and first clinical observations].

Since June 1991, a Cyclotron unit with a proton beam of 65 MeV has been working at the Institute Antoine Lacassagne in Nice, France. An international cooperative group has been founded to guarantee the thorough exploitation of the facility through complete cooperation. From June 17 to December 20, 1991, 47 patients with uveal melanoma were treated; 4 of them entered the study by means of the Italian team and were treated in cooperation with the Cyclotron staff. Treatment modalities and preliminary observations are described.
