[Results of interstitial curietherapy and combined transcutaneous radiotherapy-curietherapy in 150 patients with carcinoma of the tongue and/or mouth floor]

The authors report their experience on the treatment of carcinoma of the oral tongue and floor of the mouth with interstitial brachytherapy, alone or in combination with external irradiation. One hundred and fifty patients were treated; among these, 116 with brachytherapy alone, 34 with combined treatment. The five years local control in those patients treated with brachytherapy alone was 72.5% in T1, 61.2% in T2 and 35% in T3; in those patients treated with external irradiation and brachytherapy the global five years control was 42.5%. The global five years survival was 64% in the patients treated with brachytherapy alone and 48% in the patients treated with combined therapy.
