Design outcomes

Primary

MeasureTime frame
the change at 3 months after focal brachytherapy (FBT) from baseline in the mean 24 h urinary frequency

Secondary

MeasureTime frame
1, PSA value before FBT, and at 1,3,6,12,18,24,30,and 36 months after FBT. 2, biochemical failure free survival by Stuttgart definition (PSA nadir + 1.2ng/ml) 3, biochemical failure free survival by Phenix definition (PSA nadir + 2.0ng/ml) 4,pathological findings by saturation biopsy 36 months after FBT 5,findings on MRI 36months after FBT 6,radical treatment free suvival 7,the change at 1,3,6,12,18,24,30,and 36 months after FBT from baseline in IPSS, OABSS, QOL, SHIM, SF-8, and EPIC 8, the change at 1,3,6,and 12 months after FBT from baseline in mean volume voided per micturition, the change at 1,6,and 12 months after FBT from baseline in the mean 24 h urinary frequency 9, the change at 1,3,6,12,18,24,30, and 36months after FBT from baseline in post-voiding residual volume 10, Genitourinary and gastrointestional toxicity (CTCAE version 5.0) 11, comparison of chronological change of PSA between patients with positive findings on saturation biopsy at 36 months after FBT and those with negative findings 12,comparison with historical data (patients who underwent low-dose-rate brachytherapy between May 2010 and April 2020) in the change of IPSS, OABSS, QOL, SHIM, SF-8, EPIC, the mean 24h urinary frequency, mean volume voided per micturition, and toxicity.
