After spinal anesthesia steel or plastic needle placement performed under TRUS guidance. Pre- and post-insertion ultrasound based planning is obligatory in all cases. Two fractions of 13Gy are delivered with 2 separate implantations and 2-3 weeks interval. The CTV was defined as the prostate capsule with 1mm (low-risk) - 3 mm (intermediate risk) expansion plus proximal 1/3 of seminal vesicles. The PTV was equal to CTV. The rectum, bladder and urethra are contoured as organs at risk. The dosimetry plan objectives are the following: prostate D90 - above 104% and V100% - above 92%; urethra D10 \< 110% , rectum D2cc\<75% (below 75Gy EQD2).

Before SBRT three fiducial markers are obligatory inserted into the prostate.Planning MRI on diagnostic table with subsequent fusing with simulation CT is obligatory. CTV to planning target volume (PTV) expansion was 3-5 mm in all direction except posteriorly (in the direction of the rectum) where it is 1-3 mm. Dose must be delivered as 5 fraction of 7.25Gy. V100% for PTV ≥ 95%. Main dose constraints are as follows: D 2cm³ ≤ 36Gy for rectum (below 75Gy EQD2)., V 37.5 Gy \<5 cm³ for bladder, V 20 Gy \<10 cm³ for femoral heads. Androgen deprivation therapy is not permitted.

All treatments must be performed on conventional linear accelerators with cone beam CT guidance before each fraction, intrafractional motion monitoring is optional.

Patients were randomly assigned (1:1) to conventionally high dose rate brachytherapy or stereotactic body radiotherapy. Randomisation was done Chief researcher blinded to patient data by telephone stratification by risk group (low or intermediate).

Stereotactic ablative radiotherapy

High dose rate brachytherapy

Sergey Novikov

This is single center prospective phase 2 randomized trial aiming to compare biochemical and clinical relapse free survival and toxicity profiles of stereotactic body radiotherapy (SBRT) versus high dose rate brachytherapy (HDRB) for localized low- and intermediate risk prostate cancer patients.

Before SBRT three fiducial markers are obligatory inserted into the prostate. Simulation and every SBRT sessions are performed after bowel preparation (enema) and bladder filling (400ml).Planning MRI on diagnostic table with subsequent fusing with simulation CT is obligatory. The clinical target volume (CTV) include the prostate only (low-risk patients) or prostate and proximal 1/3 of seminal vesicles (intermediate-risk patients). CTV to planning target volume (PTV) expansion was 3-5 mm in all direction except posteriorly (in the direction of the rectum) where it is 1-3 mm. Dose must be delivered as 5 fraction of 7.25Gy. V100% for PTV ≥ 95%. Main dose constraints are as follows: D 2cm³ ≤ 36Gy for rectum (below 75Gy EQD2)., V 37.5 Gy \<5 cm³ for bladder, V 20 Gy \<10 cm³ for femoral heads. Androgen deprivation therapy is not permitted.

Patients are assessed during treatment, 4-12 weeks after the end of the treatment, every 3 months for the first year and then every 6 months till the end of the study. Normal tissue adverse events are reported according to Common Terminology Criteria for Adverse Events (CTCAE version 5.0). International prostate symptoms score (IPSS) and international index of erectile function (IIEF-5) must be assessed on each visit, maximal urinary rate and residual urine volume - annually.

Prostate cancer can be detected only in male patients
