Peritumoral ductular reaction can be a prognostic factor for intrahepatic cholangiocarcinoma.

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
backgroundPeritumoral ductular reaction (DR) was reported to be related to the prognosis of combined hepatocellular-cholangiocarcinoma and hepatocellular carcinoma. Non-mucin-producing intrahepatic cholangiocarcinoma (ICC) which may be derived from small bile duct cells or liver progenitor cells (LPCs) was known to us. However, whether peritumoral DR is also related to non-mucin-producing ICCs remains to be investigated.
methodsForty-seven patients with non-mucin-producing ICC were eventually included in the study and clinicopathological variables were collected. Immunohistochemical analysis and immunofluorescence staining for cytokeratin 19, proliferating cell nuclear antigen, and α-smooth muscle actin were performed in tumor and peritumor liver tissues.
resultsA significant correlation existed between peritumoral DR and local inflammation and fibrosis. (r = 0.357, 95% CI, 0.037-0.557; P = 0.008 and r = 0.742, 95% CI, 0.580-0.849; P < 0.001, respectively). Patients with obvious peritumoral DR had high recurrence rate (81.8% vs 56.0%, P = 0.058) and poor overall and disease-free survival time (P = 0.01 and P = 0.03, respectively) comparing with mild peritumoral DR. Compared with the mild peritumoral DR group, the proliferation activity of LPCs/ cholangiocytes was higher in obvious peritumoral DR, which, however, was not statistically significant. (0.43 ± 0.29 vs 0.28 ± 0.31, P = 0.172). Furthermore, the correlation analysis showed that the DR grade was positively related to the portal/septalα-SMA level (r = 0.359, P = 0.001).
conclusionsPeritumoral DR was associated with local inflammation and fibrosis. Patients with non-mucin-producing ICC having obvious peritumoral DR had a poor prognosis. Peritumoral DR could be a prognostic factor for ICC. However, the mechanism should be further investigated.
