Penile Metastasis From Dedifferentiated Prostate Cancer With Low PSA Levels: A Case Report.
Article in Clinical case reports, 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
Penile metastasis from prostate cancer is rare and is associated with a poor prognosis; however, there is currently a lack of high-level evidence to guide the management of this condition. This case report describes a 68-year-old male with prostate cancer who developed a penile metastasis during follow-up. This occurred despite stable prostate-specific antigen (PSA) levels after treatment with androgen deprivation therapy, combined with endocrine therapy and radiotherapy. Imaging studies and intraoperative frozen section pathology suggested a penile tumor. The patient subsequently underwent total penectomy combined with urinary diversion surgery. Postoperative histopathology confirmed poorly differentiated adenocarcinoma consistent with metastatic prostatic adenocarcinoma exhibiting morphological changes related to prior therapy. This case highlights the importance of maintaining clinical suspicion for penile metastasis in prostate cancer patients with stable PSA levels, especially in the context of tumor dedifferentiation, to facilitate early diagnosis and appropriate intervention.
