Impact of preoperative prognostic factors on survival outcomes in intrahepatic cholangiocarcinoma: a retrospective cohort study.

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
Purpose: This study assesses preoperative prognostic factors in intrahepatic cholangiocarcinoma (ICC) to improve risk assessment and inform clinical decisions, focusing on the role of lymph node dissection (LND). Methods: We conducted a retrospective analysis of 234 patients who underwent surgery for ICC at a single institution between 2010 and 2019. Prognostic factors affecting overall survival (OS) were identified through univariate and multivariable logistic regression analyses. Patients were categorized into high-, intermediate-, and low-risk groups based on the number of adverse prognostic factors. Survival curves were compared between the groups that underwent LND and those that did not within each risk category. Results: Of the 234 patients, 138 (59.0%) underwent LND, and 96 (41.0%) did not (non-LND). Significant prognostic factors included preoperative elevation of CEA (>5 ng/mL), CA 19-9 (>37 U/mL), tumor multiplicity, tumor size >5 cm, and extrahepatic invasion. These factors were associated with adverse OS (hazard ratio ranging from 1.69 to 2.54). High-risk patients had significantly lower median OS compared to intermediate and low-risk groups in both LND and non-LND cohorts, but no significant difference in median OS between LND and non-LND groups within each risk category was observed. Conclusion: Preoperative prognostic factors such as CEA, CA 19-9, tumor size, and multiplicity are vital for assessing patient risk in ICC. These factors guide clinical decision-making and emphasize the need for targeted treatment strategies, including the consideration of LND, particularly in high-risk patients. The study underscores the importance of these prognostic indicators in enhancing treatment outcomes.
