New combo therapy aims to stop liver cancer recurrence in High-Risk patients

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. The subjects voluntarily cooperated with the study and signed the informed consent, 2. Male or female, 18 years old ≤ age ≤75 years old, 3. The histopathologic diagnosis was hepatocellular carcinoma 4. R0 resection was performed within 4 to 8 weeks before recruitment (patients who were confirmed to have R0 resection by imaging and pathological examination were excluded from the study group if the residual R1, residual R2 or the margin of resection were not clear) 5. To satisfy any of the following high risk factors for postoperative recurrence of hepatocellular carcinoma: I) BCLC stage B (\> 3 tumors, regardless of size or number, at least one of which is \> 3 cm in diameter) ; ii) single tumor ≥5 cm in diameter; III) intraoperative or postoperative pathological findings of vascular invasion (including microvascular invasion and VP1/VP2 portal vein invasion) ; IV) histopathologic grade of low differentiation; v) capsular invasion or loss with unclear border; VI) direct invasion of adjacent organs 6. ECOG performance status score of 0-1 and Child-Pugh score of 5-6 7. None of the patients had received anti-tumor therapy for hepatocellular carcinoma, including systemic therapy and local therapy (except for 1-2 prophylactic TACE or HAIC 4-8 weeks after radical therapy) . 8. Subjects who received radical therapy, if required, were allowed to receive 1-2 prophylactic TACE/Haic treatments 4-8 weeks after surgery (on demand and not necessarily) Exclusion Criteria: 1. Known sarcomatoid hepatocellular carcinoma/mixed hepatocellular carcinoma-cholangiocarcinoma/fibrolamellar hepatocellular carcinoma; 2. A history of other malignancies in the past 5 years or at the same time; 3. Severe functional impairment of other important organs such as heart, brain, lung and kidney; 4. Patients with a history of immunodeficiency or autoimmune disease; 5. Evidence of tumor recurrence or metastasis before enrollment; 6.
