Multifactorial Contributors to Diagnostic Delay in a High-Risk Patient with Hepatocellular Carcinoma: A Case Report with Clinical Lessons.
Article in International medical case reports journal, 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
Background: Patients at high risk for primary liver cancer (PLC) are recommended to undergo PLC surveillance at least every six months. Alpha-fetoprotein (AFP) is a commonly used biomarker; however, approximately 15-30% of PLC cases remain AFP-negative throughout their course. Therefore, surveillance in high-risk populations should be based on liver imaging. Any newly detected or progressive lesion should be further characterized by contrast-enhanced computed tomography (CT), contrast-enhanced magnetic resonance imaging (MRI), or contrast-enhanced ultrasound, following guideline-based classification and follow-up recommendations. Case Presentation: This case details a 45-year-old Chinese male with hepatitis B virus (HBV) infection, type 2 diabetes mellitus, and a family history of PLC. As a high-risk individual for PLC, he did not undergo regular PLC surveillance for three years. During opportunistic encounters for acute myocardial infarction and abdominal pain, the attending specialists failed to appreciate the progression of liver imaging findings. In addition, the COVID-19 pandemic may have further aggravated pre-existing difficulties with follow-up and access to care, contributing to a delayed diagnosis of PLC. Conclusion: This case illustrates how a combination of physician-related, patient-related, and social-environmental factors contributed to surveillance failure and diagnostic delay in a high-risk patient with PLC. It reflects on why guideline-recommended interventions were not implemented at each healthcare encounter, how to correctly interpret AFP, and how to improve adherence to surveillance among high-risk populations for PLC. The insights from this case aim to inform systematic improvements in PLC monitoring for patients with chronic HBV infection.
