Colonic ductal adenocarcinoma case report: New entity or rare ectopic degeneration?
Article in World journal of gastrointestinal endoscopy, 2023. 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
backgroundEctopic pancreatic tissue is a congenital anomaly where a part of pancreatic tissue is located outside of the pancreas and lacks vascular or anatomical communication with it but shows the same histological features. Currently, the literature reports only two anecdotal cases of malignant transformation of colonic ectopic pancreas. CASE SUMMARY: We present a case of an 81-year-old patient presenting with anemia, with right colonic neoplasia and carbohydrate antigen 19-9 above the normal values. She underwent laparoscopic right hemicolectomy. The final histology was consistent with a primitive adenocarcinoma with ductal morphology and solid-predominant growth pattern. Benign ectopic pancreatic tissue was absent in the surgical specimen.
conclusionThe case describes a very rare complete degeneration of a colonic ectopic pancreatic tissue. However, the absence of benign ectopic pancreatic tissue in the surgical specimen is suggestive of the first description of a primitive ductal adenocarcinoma of the colon.
