On the development of an interstitial radiation protocol for a multicenter consortium. Experience with permanent low-dose rate and temporary high-dose rate 125I implants in 'failed' and 'newly diagnosed' glioblastoma patients: quality assurance methodology and a possible future adjuvant for therapeutic enhancement.

Three interstitial implant trial groups (one permanent low-dose rate 125I and two temporary high-dose rate 125I implants) in glioblastoma patients ('newly diagnosed' and 'failed') were compared to non-randomized similar control groups for efficacy. The results formed the basis for the BTCG 87-01 national implant trial. The 'pilot' trial demonstrated: 1) the effectiveness of a temporary high-dose rate 125I implant in 'failed' and 'newly diagnosed' patients; 2) the ability of a multicenter consortium to adhere to a standard protocol; 3) a methodology to insure quality assurance; and 4) the possibility of the future adjuvant application of hyperthermia using a single catheter system.
