On-demand transarterial chemoembolisation combined with atezolizumab and bevacizumab in patients with untreated hepatocellular carcinoma (TALENTACE): a multicentre, randomised, open-label, phase 3 trial.

Perform HCC surveillance with abdominal ultrasound PLUS serum AFP every ~6 months (semiannual, not annual) in adults with cirrhosis of any etiology who could benefit from HCC treatment: Child-Turcotte-Pugh A or B, and CTP C only if a liver-transplant candidate or listed. Do not surveil patients whose life expectancy is <1-2 years from comorbidity that neither transplantation nor HCC therapy can remedy, and weigh the physical, psychological and financial harms of surveillance case by case. Also surveil selected non-cirrhotic chronic HBV carriers: Asian men >40 and women >50 from endemic regions, people of African origin at younger ages, family history of HCC, or high viral load/active hepatitis. AGA 2026 endorses PAGE-B (intermediate/high risk at ≥10) and REAL-B to stratify these patients. Patients with HCV cirrhosis stay in surveillance after SVR. Patients without cirrhosis from other causes are NOT surveilled because incidence is too low (≤F3 fibrosis, MASLD without cirrhosis, HCV cured before cirrhosis), though fibrosis staging uncertainty warrants individual discussion. CT/MRI are not routine surveillance tools. Abbreviated MRI, GALAD and other blood biomarkers are investigational and should not replace ultrasound+AFP. Multicancer blood detection tests should not be used. Recall per AASLD 2023: AFP ≥20 ng/mL or a rising AFP (doubling, or a rise on two consecutive tests even below 20), any ultrasound observation ≥1 cm, or an inadequate ultrasound triggers multiphasic contrast CT or MRI read with LI-RADS. Treatment per AASLD 2023 is BCLC-linked: resection, ablation or transplant within Milan criteria for very-early/early disease, TACE and other locoregional therapy for intermediate disease, systemic therapy for advanced disease. Preferred first-line systemic therapy in Child-Pugh A is atezolizumab+bevacizumab or durvalumab+tremelimumab (STRIDE); sorafenib, lenvatinib or durvalumab monotherapy are the alternatives. BEACON-HCC (AASLD/HCC-LIVE, Hepatology 2026) is a Delphi consensus framework for treatment allocation that complements BCLC; it does not replace it. Under BEACON-HCC, macrovascular invasion does not automatically mean systemic therapy, and EBRT/SBRT and TARE are primary options. Continue post-treatment surveillance with contrast-enhanced cross-sectional imaging early after curative therapy.
