Criteria

Inclusion Criteria:

3. At the initial enrollment evaluation, patients were expected to accept radical resection of liver cancer and meet at least one of the following high-risk recurrence factors after surgery: ①There are 3 or more tumor lesions in the liver; ②The diameter of a single tumor lesion is >8cm; ③Existence macrovascular tumor thrombus; ④>5 MVI or MVI occurred in the distant paracancer tissues;

4. Before enrollment (after radical resection of liver cancer), imaging evaluation was performed to ensure that the tumor was completely removed (clear margin);

5. Must have at least 1 resectable lesion (diameter ≥2 cm);

6. ECOG score <2;

7. Child-Pugh score ≤7;

9. An estimated life expectancy of ≥3 months;

10. Participation in this clinical study voluntary, can cooperate with researchers to carry out research, and sign informed consent.

Exclusion Criteria:

8. Have received or are expected to participate in this study within 4 weeks before pretreatment to receive TIL required focus radiotherapy, or tumor evaluation focus (target focus or non-target focus) radiotherapy, or radical radiotherapy;

9. Any toxic response resulting from previous anti-tumor treatment prior to pretreatment did not return to grade 1 or below (CTCAE5.0 version);

10. Previous history of organ / stem cell transplantation or expected to be involved in this trial for organ / stem cell transplantation;

11. Left ventricular ejection fraction (LVEF)<45% or New York Heart Association (NYHA)≥ grade 2;
