MRI-guided biopsy reduces biochemical recurrence in prostate cancer patients undergoing radiation therapy: a single-center study from Thailand.

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
Accurate diagnosis of significant prostate cancer (PCa) is essential for effective treatment. Multiparametric magnetic resonance imaging (mpMRI) is increasingly used for lesion detection and biopsy guidance, but its impact on outcomes following radiotherapy remains uncertain. This study assesses the effect of MRI-guided biopsy on biochemical recurrence (BCR) following definitive external beam radiotherapy (EBRT). This single-center, retrospective review included 102 patients with localized PCa who received primary EBRT between 2018 and 2021. The MRI-guided biopsy group underwent both targeted and systematic biopsies, while the non-MRI-guided biopsy group underwent systematic biopsy alone. All patients underwent pre-treatment MRI (pre-RT MRI). Kaplan-Meier analysis compared BCR-free survival between the MRI-guided and non-MRI-guided biopsy groups. Among the 102 patients, 57 underwent MRI-guided biopsy, with 52.9% classified as intermediate-risk. The median follow-up period was 57.2 months. The proportion of very-high-risk patients was significantly greater in the non-MRI-guided biopsy group (24.4% vs. 3.5%, p = 0.01). Seventeen patients in the non-guided biopsy group were staged as T3 with the assistance of the pre-RT MRI. Despite the use of pre-RT MRI in all non-MRI-guided biopsy cases, four patients experienced BCR, whereas no BCR was observed in the MRI-guided biopsy group. The MRI-guided biopsy group demonstrated superior BCR-free survival (p < 0.01) across both intermediate- and higher-risk groups. MRI-guided biopsy was associated with a reduced risk of BCR following definitive EBRT, particularly in intermediate-risk patients. In contrast, systematic random biopsies, even when combined with pre-RT MRI, were linked to poorer intermediate oncologic outcomes.
