Sorry, but Beaquiterapia is not enabled in your browser! No grupo de baixo risco foram classificados O risco para toxicidades retais agudas e tardias foi maior quando teleterapia conformada foi utilizada. Results of the association of high dose-rate brachytherapy with external beam irradiation in prostate cancer.

Brachytherapy Iridium radioisotopes Prostatic neoplasms. Prognostic factors associated to overall and disease-free survival, as well as to braquitedapia related toxicity were also studied.

A retrospective study of patients with localized prostate adenocarcinoma treated between December and March was performed. According to the risk group, three fractions of HDR brachytherapy were delivered in the course of 24 hours, with a single implant: The interval between fractions was of at least 6 hours.


Resultados da associação de braquiterapia de alta taxa de dose à teleterapia no câncer

Conventional 2D or 3D conformal external beam irradiation was delivered to the prostate and seminal vesicles with 25 fractions of 1. Multivariate analysis was done to evaluate unfavorable prognostic factors for biochemical failure free survival BFFS.

The mean follow-up was 50 months ranging from 24 to months median 48,4 months. Death from prostate cancer occurred in 4. Biochemical failure occurred in 9.

Using the Phoenix criteria, The only feature predicting biochemical failure BF in the multivariate analysis by both ASTRO and Phoenix criteria was the presence of prostate nodules, but patients younger than 60 years presented higher chance of BF using Phoenix criteria only. They presented as grade 1 in Late urethral stenosis was observed in 8.

Acute urinary toxicity was related to previous urinary obstruction and higher brachytherapy dose to the urethra.

Late urethral stenosis brauqiterapia related to older age and higher brachytherapy dose. Grade 1 early rectal toxicity occurred in Late rectal toxicity occurred as grade 1 in 3.


The risk of acute and late rectal toxicity was higher when 3D conformal irradiation was used. Glans pain was observed in 4.

Sexual impotence presented a higher incidence in older patients with one or two co-morbidities, previous sexual impairment, or 3D conformal irradiation.

Factors related to survival and toxicity can help to better select and manage patients with localized prostate carcinoma. This document is only for private use for research and teaching activities.
