PDF, 1. Brachytherapy BT proved to be an effective and safe way for dose escalation in combination with external-beam radiotherapy EBRT [1—6]. Furthermore, multi-parametric MRI spectroscopy, dynamic contrast-enhanced- diffusion weighted images provides the possibility to visualize the highest risk of local relapse i.
Staging examinations included prostate specific prostate gland cancer mri PSA measurement, digital rectal examination, histopathology review, 1. Patient- tumor- and treatment characteristics are presented in Supplementary Tables 1 and 2.
Interventions were performed in a 0. Frompatients were placed in supine position in combination with a pelvic coil, allowing more comfortable interventions Supplementary Figure 1.
Navigation, contouring and planning were exclusively based on MR images. Details of the procedure have been previously described . The prostate was implanted via a peripheral loading technique with extra effort to insert catheters directly into any visualized tumor or tumor-bearing region s previously defined on diagnostic MRI.
Clinical target volume CTV included the prostate gland ± extraprostatic extension or root of seminal vesicles without margin. The urethra and pre-urethral strip of the central gland if no tumor present were excluded from CTV Supplementary Figure 2 .
Anterior rectal wall, intraprostatic- membranous urethra and bladder were delineated as OARs. Dose-point optimization n ¼ 7, Theraplan Plus vs.

Where it was possible, we tried to maximally cover high-risk areas and concentrate the hot spots within this site Supplementary Figure 2. Patients were seen by a radiation oncologist weekly during RT.
The follow up schedule included PSA test prostate gland cancer mri three months in the first year, every six months in the second to fifth year, and yearly thereafter. Statistical evaluation was performed with SPSSvs. Table 1. Disease control: actuarial and crude rates for all patients.
Figure 1. Biochemical relapse-free survival for all patients. Two patients developed subsequently bone metastasis, while two patients have still no evident of clinical disease. One IRPC patient had suspicious tumor prostate gland cancer mri on the bladder trigonum after 93 month followup. Due to poor general condition ECOG:4, previous strokeno PSA test, imaging studies, biopsy was performed, patient went on best supportive care and recorded as a local failure.
There was a single urinary incontinence Gr. Three urinary strictures were diagnosed, including one Gr. Frequency of late toxicities for all patients with baseline values. EPIC urinary scores recovered within 6—12 months, followed by a slight decline and stabilized from 4th-year. After a significant decline p ¼. Dosimetry results, imaging observations and working time analysis are attached in Supplementary appendix. Discussion To date only few long-term clinical results are available on MR guided-HDRBT [12,13,15—17] as reports primarily focus on clinical workflow, feasibility and cohort sizes, follow-up times are too short to address the clinical efficacy.
Our moderate dose escalation protocol with single implants follows the national and Catalan practice [2,6]. A low Gr. Despite the lack of clear correlation between dose-volume, non-dosimetry factors and stricture incidence [23,24], we believe that MR-based definition of membranous urethra might improve dose delivery and eventually decrease toxicity.
GI toxicity was generally mild with only one Gr. The observed Gr. EPIC scores revealed mainly urinary baseline symptoms and showed transient changes in both domains over time similarly to literature findings [21,22,25].
Apart from a prostate gland cancer mri decline, we noted a transient drop in GI QoL at 24 months as well.

The main reason is the patient with manifested proctitis suffered from a bowel perforation during the explorative colonoscopy. The limited number of cases with heterogeneous radiation treatment across the cohort represents the main limitation of our paper. However, the follow-up is long enough to draw a definitive conclusion on clinical outcome.
It would be excessive and premature to state that these results are directly related to MRI guidance as several patients — tumor — and treatment related factors may contribute to clinical outcome .
Although, its influence on targeted catheter placement, target and OARs definition throughout the course of the procedure could not be ignored either. Funding  There was no funding source for this study.
