Recurrence of mucinous prostate cancer in rectal wall due to needle-track seeding from previous transrectal prostate biopsy.

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
Introduction: Needle-track seeding of prostate cancer into the rectal wall following transrectal prostate biopsy is exceedingly rare. We report a case of mucinous prostate cancer recurrence in the rectal wall due to biopsy needle seeding, discovered after robot-assisted radical prostatectomy. Case presentation: A 67-year-old man underwent robot-assisted radical prostatectomy for mucinous prostate cancer (clinical stage T2cN0M0, Gleason score of 4 + 4, and initial prostate-specific antigen level of 8.8 ng/mL). Five years postoperatively, endoscopy revealed a rectal tumor, which was diagnosed as needle-track seeding from the previous transrectal prostate biopsy. Following resection of this rectal tumor, the patient's prostate-specific antigen level fell to <0.008 ng/mL. No signs of recurrence or metastasis were observed 3 months postoperatively. Conclusion: While rare, transrectal prostate biopsies can pose a small risk of needle-track seeding into the rectal wall. Endorectal examination should be considered if biochemical recurrence of prostate cancer occurs following radical prostatectomy.
