Efcacy and Safety of Postoperative Adjuvant Hepatic Arterial Infusion Chemotherapy With mFOLFOX in Hepatocellular Carcinoma With High-risk Recurrence Factors

Postoperative Adjuvant Hepatic Arterial Infusion Chemotherapy With mFOLFOX(Modified Folinic Acid, Fluorouracil, and Oxaliplatin) in Hepatocellular Carcinoma With High-risk Recurrence Factors：A Single-center, Phase II, Single-arm, Prospective Study

This is a single-center, single-arm, prospective trial to explore the efficacy and safety of postoperative adjuvant hepatic arterial infusion chemotherapy(HAIC) with mFOLFOX in hepatocellular carcinoma with high-risk recurrence factors.

Study Overview

• Status: Recruiting
• Conditions: Hepatocellular Carcinoma (HCC)
• Intervention / Treatment: Drug: mFOLFOX ：Oxaliplatin,leucovorin calcium,5-fluorouracil

Detailed Description

Patients meeting the study's inclusion criteria were enrolled, and their baseline demographic data were collected. Patients enrolled in this study received a first HAIC treatment (mFOLFOX-HAIC) 4-8 weeks after radical surgery. A second HAIC session was administered 3 weeks later, depending on individual patient conditions, with a maximum of two treatments. The protocol specified: Oxaliplatin 85 mg/m²via arterial infusion for 2-3 hours, leucovorin calcium 400 mg/m² for 1-2 hours, followed by a 400 mg/m²arterial infusion of 5-fluorouracil for 5 minutes , and continuous arterial infusion at 2400 mg/m²for 46 hours.

Follow-up was conducted every 8-12 weeks until 12 months postoperatively or the termination of the study. The follow-up included the patient's survival status, tumor recurrence, adverse drug reactions,routine blood tests, liver function, and electrocardiogram.Contrast-enhanced abdominal CT (layer thickness ≤5 mm) or contrast-enhanced MRI (including DWI sequence) were used for tumor recurrence.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult; Older Adult
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

1. Age ≥18 years and ≤75 years.
2. Histologically/cytologically confirmed hepatocellular carcinoma (HCC) (fibrotic HCC and mixed HCC/biliary carcinoma subtypes were excluded from inclusion criteria), with no prior treatment for HCC (including but not limited to chemotherapy, targeted therapy, immunotherapy, cell therapy, local radiotherapy, and interventional therapy) before surgery.
3. Patients who underwent radical surgery within the first 8 weeks and meet the following criteria: a. Histologically confirmed negative surgical margins (R0) for radical surgery: 1) No residual cancer on gross intraoperative or postoperative imaging; 2) Liver margins>1cm from tumor boundary, or margins ≤1cm with no tumor cell remnants in resected pathological tissue; b. Imaging examination (enhanced chest CT, abdominal CT or MRI, pelvic CT or MRI) performed ≥4 weeks after surgical resection or ablation to confirm complete radiological response.
4. ECOG score ranges from 0 to 1.
5. Patients meeting any of the following high-risk factors for hepatocellular carcinoma recurrence after radical surgery: 1) Single tumor>5 cm 2) Concurrent vascular invasion (microvascular invasion or major vessel invasion Vp1-2) 3) Multiple lesions with ≥3 tumors 4) Tumor grade Edmondson III-IV 5) Surgical margin ≤1cm
6. For patients with preoperative AFP elevation, post-radical surgery or ablation, AFP levels must have significantly decreased and show no significant upward trend.
7. Subjects with Hepatitis B or C Virus(HBV or HCV) infection must undergo standardized antiviral therapy prior to enrollment and continue the treatment during the study period.
8. The patient must have adequate organ and bone marrow function, with laboratory test values meeting the following criteria: 1) Complete blood count (CBC): Absolute neutrophil count (ANC) ≥1.5×10⁹/L; platelet count (PLT) ≥80×10⁹/L; hemoglobin (Hb) ≥90 g/L; 2) Liver function: Serum totalbilirubin (TBIL) ≤2×upper limit of normal (ULN), or direct bilirubin ≤ULN for subjects with TBIL>2×ULN; alanineaminotransferase (ALT) and aspartate aminotransferase (AST) ≤3×ULN; serum albumin ≥28 g/L; 3) Renal function: Serum creatinine (Cr) ≤1.5×ULN, or creatinine clearance (CCr) ≥45 mL/min (Cockcroft-Gault formula) for subjects with Cr>1.5×ULN; 4) Urinalysis shows urine protein <2+; For subjects with baseline urinalysis showing proteinuria ≥2+ in routine urine tests, 24-hour urine collection should be performed with 24-hour urine protein quantification <1g; 5) Coagulation function: International Normalized Ratio (INR) or Activated Partial Thromboplastin Time (APTT) ≤1.5×Upper Limit of Normal (ULN).

Exclusion Criteria:

1. Presence of extrahepatic metastasis, residual lesions, or recurrence on imaging after surgery or ablation.
