Summary
Percutaneous ethanol injection therapy is effective for small liver cancers, especially when the injected volume exceeds tumor size. It also improves outcomes for hepatocellular carcinoma unresponsive to chemoembolization.
Area of Science:
- Hepatobiliary surgery
- Interventional radiology
- Oncology
Context:
- Percutaneous ethanol injection (PEI) is a non-vascular intervention for liver cancer.
- Optimal PEI requires injecting 1.5 times the tumor volume.
- PEI is best for small hepatocellular carcinoma (HCC) < 3 cm.
Purpose:
- To evaluate the efficacy of PEI in treating liver cancer.
- To determine optimal PEI protocols for hepatocellular carcinoma (HCC).
- To explore the combined use of PEI with transcatheter chemoembolization (TCE).
Summary:
- PEI alone is effective for small HCC (< 3 cm) when injected volume is >1.5 times tumor volume.
- Combined PEI and TCE improves outcomes in HCC cases with collateral blood supply, obstructed hepatic arteries, or poor Lipiodol retention.
- PEI can manage giant HCC, HCC with obstructive jaundice, and intraportal tumor thrombus.
Impact:
- PEI offers an effective treatment option for specific liver cancer cases.
- PEI can improve therapeutic results when transcatheter chemoembolization is insufficient.
- PEI demonstrates versatility in managing complex HCC presentations, including thrombus relief.
