Brief Summary

Surgical resection is the primary curative treatment for patients with hepatocellular carcinoma (HCC), with a 5-year overall survival rate of 60-80% post-surgery. Therefore, guidelines recommend surgical resection as the first-line choice for early to mid-stage HCC (CNLC stages IA-IIA or BCLC stages A/B) patients with well liver reserve function. However, the high postoperative recurrence rate is the main factor limiting long-term survival in HCC patients, with literature reporting recurrence rates exceeding 70%. Among these, half of the patients experience recurrence within two years post-surgery, imposing a heavy burden on patients' physical and mental health as well as on societal medical resources. Adopting effective treatment to improve surgical curability and reduce postoperative recurrence rates is one of the current research hotspots. Recent studies from the investigators' center indicate that hepatic arterial infusion chemotherapy (HAIC) and immunotherapy can provide definite efficacy for patients with advanced HCC, extending their survival time. Mechanistically, chemotherapy and immunotherapy have synergistic effects: tumor cell necrosis induced by chemotherapy can promote immune activation, while cytokines and neutralizing antibodies secreted by immune cells can enhance the toxicity of chemotherapeutic drugs. Therefore, this study aims to conduct a prospective, single-arm, phase II clinical study, targeting HCC patients with high-risk recurrence factors, to evaluate whether neoadjuvant HAIC combined with a PD-1 monoclonal antibody (Tislelizumab) followed by adjuvant Tislelizumab post-surgery can reduce postoperative recurrence rates in HCC patients. The primary endpoint is the 1-year recurrence-free survival (RFS) rate post-surgery, while secondary endpoints include the objective response rate (ORR) of neoadjuvant therapy, the incidence of perioperative complications, the incidence of treatment-related adverse events, overall survival (OS) time, pathological complete response (pCR) rate of neoadjuvant therapy, and major pathological response (MPR) of neoadjuvant therapy. The investigators aim to comprehensively assess the efficacy and safety of neoadjuvant HAIC plus PD-1 and adjuvant PD-1 in the perioperative treatment of HCC.

Conditions

Hepatocellular Carcinoma; Beyond Milan Criteria

Outcome Measures

Primary Outcomes (1)

• recurrence free survival, RFS

  RFS is defined as the time from treatment to post-resection tumor recurrence or death from any cause.

  From date of treatment beginning until the date of first documented tumor recurrence or date of death from any cause, whichever came first, assessed up to 1 years

Secondary Outcomes (5)

• objective response rate，ORR

  From date of neoadjuvant treatment beginning until the date of neoadjuvant treatment completion, up to 1 year.

• pathological complete response，pCR

  From date of neoadjuvant treatment beginning until the date of surgical resection completion, , up to 1 year.

• overall survival, OS

  From date of treatment beginning until the date of death from any cause, assessed up to 1 years.

• perioperative complication rate

  The period from the start of surgery to the patient's discharge from hospital, up to 1 year.

• Incidence of adverse events (safety )

  From date of neoadjuvant treatment beginning until the date of adjuvant treatment completion, up to 2 year.

Study Arms (1)

Experimental arm

EXPERIMENTAL

Two cycles of FOLFOX-HAIC combined with tislelizumab as neoadjuvant therapy, followed by surgical resection and four cycles of adjuvant tislelizumab.

Drug: Neoadjuvant HAIC and PD-1 Plus Adjuvant PD-1

Interventions

Neoadjuvant HAIC and PD-1 Plus Adjuvant PD-1 DRUG

Patients will first receive two cycles of FOLFOX-HAIC combined with tislelizumab as neoadjuvant therapy, with a 3-week interval between cycles. Two weeks after completing the neoadjuvant therapy, imaging assessments will be conducted to evaluate treatment efficacy and surgical feasibility. Surgical resection should be performed within two weeks following the imaging assessment. Four weeks post-resection, patients will undergo a follow-up evaluation to assess postoperative recovery and determine the presence of any residual tumor. If no residual or recurrent tumor is detected, adjuvant therapy with tislelizumab will commence (every three weeks, for a total of four cycles).
