Zapping liver tumors to make them operable
NCT ID NCT07832006
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers test whether irreversible electroporation, a technique that uses electrical pulses to destroy tumor cells while sparing nearby blood vessels and bile ducts, can boost the effects of lenvatinib and sintilimab in people with advanced hepatocellular carcinoma that cannot be surgically removed. Participants receive the drug combination with or without the electroporation procedure. The study measures how many tumors shrink and how many patients become eligible for curative surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- irreversible electroporation combined with lenvatinib and sintilimab
- What this could lead to
- If it works, this approach could make surgery possible for more people whose liver cancer cannot be removed at diagnosis.
- What could go wrong
- The trial is small and single-center, so results may not apply broadly. Combining ablation with drugs and immunotherapy can cause liver injury, bleeding, or immune-related side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 to 75 years. * Clinically or pathologically confirmed hepatocellular carcinoma (HCC). * Unresectable HCC corresponding to CNLC stage IIa, IIb, or IIIa, without extrahepatic metastasis. * At least one measurable lesion according to RECIST version 1.1. * Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. * Child-Pugh class A or B liver function. * Adequate organ function, including an absolute neutrophil count ≥1.5 × 10⁹/L; platelet count ≥75 × 10⁹/L; hemoglobin ≥80 g/L; serum creatinine ≤1.5 × the upper limit of normal (ULN) or creatinine clearance ≥50 mL/min; total bilirubin ≤3 × ULN; and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤5 × ULN. * Suitable for treatment with lenvatinib and sintilimab according to institutional standards. * Able to understand and sign written informed consent. Exclusion Criteria: * Presence of extrahepatic metastasis. * Previous treatment with irreversible electroporation. * Prior systemic therapy that precludes treatment with lenvatinib or sintilimab. * Diffuse infiltrative HCC not suitable for IRE evaluation. * Uncontrolled ascites, hepatic encephalopathy, or active gastrointestinal bleeding. * Active severe infection requiring systemic treatment. * Active tuberculosis. * Uncontrolled hepatitis B virus replication despite antiviral therapy. * Clinically significant cardiovascular disease, including uncontrolled hypertension, recent myocardial infarction, unstable angina, or severe arrhythmia. * Concurrent malignancy requiring active treatment. * Pregnancy or breastfeeding. * Any condition that, in the investigator's judgment, would interfere with study participation or interpretation of the study results.
