Summary
Percutaneous microwave coagulation therapy effectively treated residual hepatocellular carcinoma in a patient with cirrhosis. This minimally invasive technique offers a safe and viable option for superficial liver tumors.
Area of Science:
- Hepatobiliary Medicine
- Interventional Radiology
- Oncology
Background:
- Hepatocellular carcinoma (HCC) recurrence post-treatment necessitates effective management strategies.
- Superficial liver tumors, particularly in cirrhotic patients, present unique therapeutic challenges.
- Arterial embolization therapy is a common treatment for HCC, but residual disease can occur.
Observation:
- A 67-year-old male patient presented with residual HCC on the anterior and inferior surfaces of liver segment 6 post-arterial embolization.
- Percutaneous microwave coagulation therapy (PMCT) was selected for treatment of the residual tumor.
- Tumor location on superficial liver surfaces was noted.
Findings:
- PMCT was performed safely, achieving complete tumor ablation.
- Post-treatment contrast-enhanced computed tomography (CT) revealed a non-enhancing treated tumor.
- Two-year follow-up demonstrated sustained tumor non-enhancement and size reduction on contrast-enhanced CT.
Implications:
- PMCT is a safe and effective treatment modality for residual HCC, even in patients with underlying cirrhosis.
- This technique provides a valuable option for managing superficial liver tumors that may be difficult to treat with other methods.
- Successful PMCT suggests potential for improved outcomes in patients with challenging HCC presentations.
