Interstitial Brachytherapy (LDR-Brachytherapy) in the Treatment of Patients with Prostate Cancer
Objectives: As the number of patients with prostate cancer treated with permanent radioactive implants is increasing world wide, long-term data on tumor control and treatment morbidity become available. Materials: Biochemical and clinical tumor control appears to be as effective as after radical prostatectomy or external beam radiation therapy in early prostate cancer. Results: The risk of post...
متن کاملDeveloping a Treatment Planning Software Based on TG-43U1 Formalism for Cs-137 LDR Brachytherapy
BACKGROUND The old Treatment Planning Systems (TPSs) used for intracavitary brachytherapy with Cs-137 Selectron source utilize traditional dose calculation methods, considering each source as a point source. Using such methods introduces significant errors in dose estimation. As of 1995, TG-43 is used as the main dose calculation formalism in treatment TPSs. OBJECTIVES The purpose of this stu...
متن کاملContrast-enhanced ultrasound as support for prostate brachytherapy treatment planning
PURPOSE To investigate the possibility of localization of intraprostatic lesions (IL) with contrast-enhanced ultrasound (CEUS) to support the brachytherapy treatment planning of temporary implants. MATERIAL AND METHODS Two brachytherapy treatment plans were generated for 8 patients treated with external beam radiotherapy and pulsed-dose rate brachytherapy boost for prostate cancer. The first ...
متن کاملThe use of nomograms in LDR-HDR prostate brachytherapy
PURPOSE The common use of nomograms in Low Dose Rate (LDR) permanent prostate brachytherapy (BT) allows to estimate the number of seeds required for an implant. Independent dosimetry verification is recommended for each clinical dosimetry in BT. Also, nomograms can be useful for dose calculation quality assurance and they could be adapted to High Dose Rate (HDR). This work sets nomograms for LD...
متن کاملdeveloping a treatment planning software based on tg-43u1 formalism for cs-137 ldr brachytherapy
conclusions according to the results, the old dosimetry formalisms, overestimate the dose especially towards the applicator’s tip. while the tg-43u1 based software perform the calculations more accurately. results for a typical arrangement of 10 active pellets in the applicator, the percentage difference between doses obtained by the new algorithm at 1cm distance from the tip of the applicator ...
