Summary
Microwave coagulation therapy offers a safe and potentially curative option for unresectable hepatocellular carcinoma, especially in patients with advanced liver cirrhosis. This minimally invasive treatment showed promising results in tumor ablation and patient survival.
Area of Science:
- Hepatobiliary surgery
- Minimally invasive oncology
- Interventional radiology
Background:
- Surgical resection is not always feasible for hepatocellular carcinoma.
- Microwave coagulation therapy (MCT) is an alternative treatment modality.
- Evaluating MCT efficacy in unresectable cases is crucial.
Purpose of the Study:
- To evaluate the efficacy and safety of microwave coagulation therapy (MCT) for patients with unresectable hepatocellular carcinoma.
- To assess outcomes in patients with advanced liver cirrhosis and multifocal or central tumors.
Main Methods:
- Nineteen patients with unresectable hepatocellular carcinoma underwent MCT via laparotomy, laparoscopy, or thoracotomy.
- Treatment targeted single or multiple nodules (5-90 mm).
- Patient outcomes, including tumor ablation, recurrence, and survival, were monitored.
Main Results:
- MCT achieved reproducible regional necrosis and complete tumor ablation in 28 of 31 treated nodules.
- Local recurrence was observed in only 2 patients after laparoscopic MCT.
- Patients demonstrated rapid recovery, and 13 patients (including 2 long-term survivors) were alive at follow-up.
Conclusions:
- Microwave coagulation therapy is a safe and potentially curative option for hepatocellular carcinoma.
- MCT is effective in patients with advanced liver cirrhosis and multifocal or central tumors.
- This preliminary study highlights MCT's potential as an alternative to resection.
