CHOLANGIOCARCINOMA: EPIDEMIOLOGY, HISTOPATHOLOGY, AND POTENTIAL PROGNOSTIC AND THERAPEUTIC IMPLICATIONS IN A COHORT FROM A REFERENCE CENTER IN SOUTHERN BRAZIL.

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 a rare neoplasm, with high mortality, originating in the bile ducts. Its incidence is higher in Eastern countries due to the endemic prevalence of liver parasites. Factors such as metabolic syndrome, smoking, and pro-inflammatory conditions are also linked to the disease. Clinical features include asthenia, abdominal pain, cholestasis, and increased serum levels of CEA and CA19-9.
aimsThe aim of this study was to evaluate CCA prevalence, survival, and potential prognostic and therapeutic implications in a patient cohort and assess correlations with clinical laboratory data and possible associated risk factors.
methodsThis is a retrospective study of the clinical and histological data of patients diagnosed with CCA at Santa Casa de Misericórdia in Porto Alegre, Brazil, between 2016 and 2021.
resultsThere was a 56% prevalence of CCA in women, with intrahepatic localization in 55.4% of cases and unifocality in 85.6% of patients. The mean age of the patients was 63 years (26-89 years), with a mean tumor size of 5.5 cm. The median survival time was 7 months (0 to >50). CA19-9 was altered in 81% of patients, whereas GOT/GPT was altered in 62.5% and gamma-glutamyl transferase/alkaline phosphatase/bilirubin in 69.1% of patients. Mortality was higher among patients with extrahepatic CCA.
conclusionRisk factors such as smoking, cholecystectomy, cirrhosis, intrahepatic lithiasis, and transplantation should be considered individually by the attending physician for radiological monitoring and incidental discovery of the neoplasm. Lack of timely identification by the attending physician can delay diagnosis, increasing mortality.
