Résumé

PURPOSE: To analyse a new technique for prostate brachytherapy with permanent Iodine implants characterized by the use of a seed projector after a 3D dosimetric peroperative treatment planning (FIRST technique). PATIENTS AND METHOD: 395 patients have been treated in France with this technique in six radiotherapy centres between November 2002 and December 2005 for a localized prostate cancer. RESULTS: Thirteen patients (3.3%) developped a urinary retention, and respectively 7.8 and 26.5% an acute RTOG grade 3 and 2 toxicity. The 6-weeks IPSS score was equal or lower to 15 in 73% with a 11 median IPSS value. A failure of the loading with the seed-projector, leading to a manual loading of the seeds, occurred in 9 patients (2.3%) in two centres, directly related to the loading procedure with the seed-projector in 5 cases. The median duration of the procedure was reduced by 30 minutes for the patients treated in 2005. CONCLUSIONS: This multicenter study establishes the feasibility of the routine use of a seed projector for permanent iodine 125 prostate implants with an initial tolerance similar to the best results published for other implants techniques.
