Refining prostate seed brachytherapy: Comparing high-, intermediate-, and low-activity seeds for I-125 permanent seed prostate brachytherapy.

Purpose: To analyze the difference in prostate coverage and dose to the rectum in men with prostate carcinoma treated with permanent seed brachytherapy with different seed activities.

Methods: Forty-nine patients treated with iodine-125 permanent seed prostate brachytherapy with low-activity seeds of 0.30-0.

Urethra-sparing, intraoperative, real-time planned, permanent-seed prostate brachytherapy: toxicity analysis.

Purpose: To report the toxicity outcome in patients with localized prostate cancer undergoing (125)I permanent-seed brachytherapy (BT) according to a urethra-sparing, intraoperative (IO), real-time planned conformal technique.

Methods And Materials: Data were analyzed on 250 patients treated consecutively for low- or intermediate-risk prostate cancer between 2005 and 2009. The planned goal was urethral V(150) = 0.

Comparison between high and low source activity seeds for I-125 permanent seed prostate brachytherapy.

Purpose: To compare low (mean 0.44, SD ± 0.0163 mCi) with high source activity (0.

Total body irradiation with a reconditioned cobalt teletherapy unit.

While the current trend in radiotherapy is to replace cobalt teletherapy units with more versatile and technologically advanced linear accelerators, there remain some useful applications for older cobalt units. The expansion of our radiotherapy department involved the decommissioning of an isocentric cobalt teletherapy unit and the replacement of a column-mounted 4-MV LINAC that has been used for total body irradiation (TBI). To continue offering TBI treatments, we converted the decommissioned cobalt unit into a dedicated fixed-field total body irradiator and installed it in an existing medium-energy LINAC bunker.
