Accumulating Genetic Mutations from Primary to Secondary Biliary Tract Cancers: Analysis of Four Patients With Metachronous Biliary Tract Cancer Using Comprehensive Genomic Profiling.
Article in Cancer genomics & proteomics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND/
aimMetachronous biliary tract cancer (BTC) is a rare occurrence after curative resection of primary BTC. The genetic alterations and pathogenesis associated with metachronous BTC remain poorly understood. PATIENTS AND
methodsWe analyzed four patients with metachronous BTC who underwent resection at the Nagoya University Hospital between 2010 and 2024. Gene panel examination was performed on both primary and secondary tumors using next-generation sequencing.
resultsThe median interval between resection of the primary tumor and diagnosis of metachronous BTC was 24 months. Genetic alterations were observed in all paired primary and metachronous carcinomas. The number of genetic mutations was higher in metachronous lesions than in primary lesions.
conclusionThis study demonstrated that characteristic genetic alterations and their accumulation play important roles in metachronous BTC. This suggests that the increasing burden of gene mutations may play a crucial role in the carcinogenesis of metachronous BTC. Further investigation is required to validate these findings and elucidate the underlying molecular mechanisms.
