Oncological outcomes of I125low dose brachytherapy in localized prostate cancer.
Article in The Canadian journal of urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLow-dose rate (LDR) prostate brachytherapy is a recommended treatment of localized prostate cancer in current guidelines. The study aimed to determine biochemical relapse-free survival (BRFS) in patients treated with dynamic real-time low-dose rate (LDR) brachytherapy using Iodine 125 (I125).
methodsWe retrospectively reviewed 499 patients with localized prostate cancer treated with I125 LDR real-time brachytherapy between 2003 and 2021. The mean patient age was 65 years (range: 45-84 years). Based on the National Comprehensive Cancer Network (NCCN) risk classification, 230 patients (46.1%) were categorized as low risk, 235 (47.1%) as intermediate risk, and 34 (6.8%) as high risk. Gleason scores were distributed as follows: 3+3 in 283 cases (56.7%), 3+4 in 157 cases (31.5%), 4+3 in 46 cases (9.2%), and 4+4 in 13 cases (2.6%). The mean follow-up was 70.5 months.
resultsTumor relapse was observed in 47 patients (9.4%) over a mean follow-up period of 6.26 years (SD 4.16). Local recurrence within the prostate occurred in 20 cases (4%). Patients with nadir PSA <0.2 ng/mL at 5 years of follow-up had a significantly lower incidence of tumor recurrence (3%) compared to those with a nadir PSA >0.2 ng/mL (21.9%) (p = 0.0001). Biochemical relapse-free (BRFS) rates at 5, 10 and 15 years were 96%, 91.5% and 88.9%, respectively. When stratified by NCCCN risk groups, 5-year BRFS was 96% in low risk, 98% in intermediate risk and 85% in high risk patients (p = 0.003). In multivariate analysis, only age at the time of brachytherapy (p = 0.009), initial PSA (p = 0.007) and Gleason grade (p = 0.007) were significantly associated with tumor recurrence. Cancer-specific survival and overall survival were 99.8% and 98.0%, respectively.
conclusionsLDR with I125 has excellent long-term oncological outcomes for patients with low and intermediate-risk prostate cancer, in particular, patients achieving a nadir PSA <0.2 ng/mL at 5 years post-treatment.
