Role of Adjuvant Chemotherapy in Distal Cholangiocarcinoma.
Article in Journal of hepato-biliary-pancreatic sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundRecent studies addressing the role of adjuvant chemotherapy (AC) in cholangiocarcinoma (CCA) have been published; however, there are challenges in generalizing the findings due to different prognostic characteristics depending on tumor location and resectability. Therefore, this study aimed to investigate the role of AC in distal cholangiocarcinoma (dCCA), a common tumor subtype of CCA.
methodData from 497 patients with dCCA who underwent curative surgery at Seoul National University Hospital between 2000 and 2019 were reviewed using prospectively collected clinicopathologic information.
resultsThe median overall survival (OS) and recurrence-free survival (RFS) in the entire cohort were 62.9 and 44.0 months, respectively. AC was associated with improved five-year OS (58.5% vs. 46.4%; p < 0.001) and RFS (49.9% vs. 40.7%; p = 0.005), particularly in patients with advanced T stages (≥ T3). Multivariate analysis revealed that AC was an independent positive prognostic factor for survival. Furthermore, adjuvant radiotherapy (RT) alone provides no survival benefit, whereas AC combined with RT (AC + RT) offers greater benefits, particularly for patients with positive resection margins.
conclusionAC improved the postoperative survival outcomes of patients with dCCA who underwent curative surgery. Furthermore, AC + RT appears to provide greater benefits, especially for patients with positive resection margins.
