Summary
Transcatheter arterial embolization (TAE) offers high diagnostic accuracy for hepatocarcinoma but rarely changes treatment plans. Its risk-benefit ratio, especially with mechanical embolization, is unfavorable, with limited clinical benefit shown.
Area of Science:
- Hepatobiliary Surgery
- Interventional Radiology
- Oncology
Background:
- Hepatocellular carcinoma (HCC) management requires accurate diagnosis and staging.
- Transcatheter arterial embolization (TAE) is an interventional radiology technique.
- Evaluating TAE's role in potentially surgical HCC cases is crucial.
Purpose of the Study:
- Assess transcatheter arterial embolization (TAE) reliability in altering diagnosis, staging, and treatment for potentially surgical hepatocarcinoma.
- Compare TAE outcomes with primary liver resection.
- Analyze TAE-related mortality and morbidity.
Main Methods:
- Thirty-nine patients with hepatocarcinoma underwent TAE.
- Diagnostic accuracy, tumor size reduction, and necrosis percentage were evaluated.
- Results were compared to 62 patients undergoing primary liver resection.
Main Results:
- TAE identified more lesions than other methods, excluding 4 patients (10.2%) from surgery.
- TAE-related mortality (1 patient) and severe morbidity (11 patients) excluded 4 additional patients.
- Tumor size reduction was minimal; necrosis >70% in 13/29 resected tumors. Complications linked to Gelfoam embolization (p<0.01).
Conclusions:
- TAE demonstrates high diagnostic accuracy but has limited impact on treatment decisions post-evaluation.
- The risk-benefit ratio of TAE is unfavorable, particularly with mechanical embolization.
- Clinical benefit of TAE in this context is not clearly evident.
