Novel blood signature for hepatocellular carcinoma screening.
Article in ESMO gastrointestinal oncology, 2025. 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
Background: Alpha-fetoprotein is commonly used for hepatocellular carcinoma (HCC) screening in at-risk populations, but its effectiveness is limited. Routine blood tests offer insights into cancer-related conditions and improve detection in other cancers. This study explores the postulated changes in routine blood tests of HCC patients, allowing the development of routine blood-based artificial intelligence for early HCC detection. Patients and methods: This population-based retrospective study analyzed patient records from 2000 to 2018 from the Hong Kong Hospital Authority Data Collaboration Laboratory. Patients with chronic liver disease (CLD), both with and without HCC, were identified using ICD codes, antiviral drug history, virology tests, and radiology reports. Those with decompensated CLD were excluded. Routine blood tests included complete blood count, liver function test, renal function test, and clotting profiles, with records collected within 1 month before HCC diagnosis. Statistical analyses included descriptive statistics and the Mann-Whitney Results: The cohort comprised 223 862 patients, including 31 149 with HCC (13.9%). Statistical analysis revealed a distinct blood signature for HCC patients, characterized by significant liver function derangement (elevated alanine aminotransferase, alkaline phosphatase, bilirubin, aspartate aminotransferase; decreased albumin), signs of systemic inflammation (lower lymphocyte count, red cell distribution width), bleeding tendencies (prolonged prothrombin time, activated partial thromboplastin time; low platelet count), and indications of cachexia (lower albumin, creatinine, urea)-all statistically significant ( Conclusions: This study presents a novel blood signature for HCC detection based on extensive clinical data. The unique spectral characteristics effectively differentiate HCC from CLD controls, supporting the potential for machine learning models in HCC detection.
