A Retrospective Multicenter Study Identifies a Similar Overall Survival of Patients After Liver Transplantation With Incidental Cholangiocarcinoma Compared to Hepatocellular Carcinoma.

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
backgroundCholangiocarcinoma (CCA) is the second most common liver malignancy with a dismal prognosis. Liver transplantation of patients with CCA is currently no treatment option backed by guidelines for most of the patients, mainly because of presumably worse outcome. This study identified cases of incidental CCA (incCCA) in three German transplant centers, that is, CCAs unexpectedly found in liver explants, and analyzed the outcome in comparison to patients transplanted because of hepatocellular carcinoma (HCC).
methodsHistopathology reports of liver explants from patients transplanted between 2002 and 2021 in three transplant centers (Hanover, Mainz, and Munich) were screened. Cases of incidental biliary tract cancer were classified according to tumor node metastasis (TNM) staging and anatomic location. Overall (OS) and disease-free survival (DFS) were analyzed and compared to patients transplanted due to HCC fulfilling the Milan criteria.
resultsA total of 19 incCCA and 140 HCC patients were included in this analysis. IncCCA was a rare finding in liver explants and occurred most frequently in patients with primary sclerosing cholangitis (63%). Mean follow-up of CCA patients was 61 (range, 4-254) months. Interestingly, OS and DFS of incCCA patients were not significantly different from patients transplanted with HCC (OS: p = 0.31; DFS p = 0.25). However, OS and DFS of incCCA patients differed significantly based on tumor location (OS HCC: N/A, intrahepatic CCA/perihilar CCA: 133 months, distal CCA/gallbladder: 6.5 months; p = 0.005; DFS HCC: 146 months, intrahepatic CCA/perihilar CCA: 133 months, distal CCA/gallbladder 5 months; p = 0.006).
conclusionOS of patients diagnosed with incCCA was similar to HCC patients. These results add data to support transplantation of specific CCA patients as a reasonable treatment option.
