Lymph Node Metastasis Around the Common Hepatic Artery Is Associated With Dismal Prognosis in Patients Undergoing Resection of Extrahepatic 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
backgroundLymph node (LN) metastasis in extrahepatic cholangiocarcinoma (eCCA) is associated with poor prognosis, but the impact of specific metastatic sites is unclear. This study investigated the clinical significance of LN metastasis around the common hepatic artery (N [CHA]) in eCCA.
methodsA total of 291 patients who underwent curative resection for eCCA between 2002 and 2022 were retrospectively reviewed. Patients were classified as N1 (CHA), N1 (other, regional LN metastasis without CHA), or N0. Clinical characteristics and long-term outcomes were compared. The short-to-long axis ratio (SLR) of CHA nodes on preoperative CT was evaluated for diagnostic value.
resultsOf 291 patients, 164 had perihilar and 127 had distal cholangiocarcinoma. The N1 (CHA), N1 (other), and N0 groups included 33, 103, and 155 patients, respectively. Five-year cancer-specific survival (CSS) rates were 6.9% (N1 [CHA]), 24.7% (N1 [other]), and 60.3% (N0). N1 (CHA) and N1 (other) had CSS hazard ratios of 3.34 and 1.86, respectively (p < 0.01). The area under the receiver operating characteristics curve for SLR in predicting N1 (CHA) was 0.779.
conclusionsN1 (CHA) is a strong negative prognostic factor in eCCA. CHA node status may serve as a useful imaging-based marker of biological resectability.
