A case of synchronous double primary combined hepatocellular-cholangiocarcinoma complicated with gallbladder adenocarcinoma: a rare case report.
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Multiple Primary Cancers (MPCs), especially synchronous combined hepatocellular-cholangiocarcinoma (cHCC-CCA) complicated with gallbladder adenocarcinoma, are extremely rare clinically. This case report discusses a 73-year-old female patient presenting with distending pain in the right upper abdomen, nausea, and weight loss. Contrast-enhanced abdominal computed tomography (CT) and liver-specific contrast-enhanced magnetic resonance imaging (MRI) revealed a space-occupying lesion in segment S4 of the liver (considered cholangiocarcinoma) and a nodular lesion in the gallbladder wall (considered neoplastic lesion). The patient underwent open surgery, and postoperative pathology and immunohistochemical examinations confirmed: the left hemihepatic lesion was cHCC-CCA (90% moderately differentiated cholangiocarcinoma and 10% moderately differentiated hepatocellular carcinoma), the gallbladder lesion was moderately differentiated adenocarcinoma, and no cancerous tissue involvement was found at the resection margins of the liver and gallbladder. After postoperative multidisciplinary team (MDT) discussion, the diagnosis of synchronous double primary tumors of the liver and gallbladder was confirmed. The patient recovered well after surgery, and the abdominal pain symptoms were significantly improved. This is the first reported case of synchronous double primary cHCC-CCA complicated with gallbladder adenocarcinoma at home and abroad.
