Article Synopsis
- A study compared the effectiveness and side effects of smaller 0.5-mm (125)I seeds in 20-gauge needles versus standard 0.8-mm seeds in 18-gauge needles for prostate brachytherapy.
- Researchers analyzed dosimetry data and acute urinary retention among 200 patients and evaluated toxicity through surveys and physical exams.
- Results showed that the 20G group had better dosimetry and significantly less perineal pain and bruising, with similar rates of urinary retention and other side effects between the two groups.
Objectives: To determine whether there is an optimal type of mathematical equation for predicting seed and activity requirements for permanent prostate brachytherapy.
Methods: Four institutions with extensive brachytherapy experience each submitted details of more than 40 implants. The data was used to generate power and linear equations to reflect the relationship between preimplant volume and the number of seeds implanted, and preimplant volume and the total implant activity.
Purpose: To describe, step-by-step, the current Seattle preplan technique, and report the dosimetric outcomes on 1,131 consecutively such treated prostate brachytherapy patients.
Methods And Materials: One thousand one hundred thirty one patients with prostate cancer were treated with iodine-125 ((125)I), palladium-103 ((103)Pd), or cesium-131 ((131)Cs) using a preplanned template-guided transrectal ultrasound-guided approach between January 2005 and August 2007. Day one computed tomography (CT) scans were taken for postimplantation dose-volume histogram evaluations.
Purpose: Despite the existence of guidelines for permanent prostate brachytherapy, it is unclear whether there is interinstitutional consensus concerning the parameters of an ideal implant.
Methods And Material: Three institutions with extensive prostate brachytherapy expertise submitted information regarding their implant philosophy and dosimetric constraints, as well as data on up to 50 radioiodine implants. Regression analyses were performed to reflect each institution's utilization of seeds and implanted activity.
