Metastatic prostate cancer mimicking colorectal cancer: a rare case of peritoneal and mesocolic lymph node involvement.
Article in Journal of surgical 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
Metastatic prostate cancer seldom involves the gastrointestinal tract, with simultaneous peritoneal and mesocolic nodal spread and is unreported in literature. We describe the case of a 93-year-old man with stable metastatic prostate cancer who presented with sigmoid obstruction secondary to sigmoid adenocarcinoma. Pathological assessment of the specimen confirmed sigmoid adenocarcinoma as well as prostate cancer deposits in colonic serosa, peritoneum, and mesocolic nodes that was not evident on preoperative imaging. This case highlights a previously undocumented metastatic pattern, the limitations of conventional imaging, and the importance of intra-operative vigilance in dual malignancies.
