What this trial studies

This observational study aims to gather data on the efficacy and safety of microwave ablation (MWA) for patients with primary and secondary liver malignancies and small renal tumors. It will evaluate the short, medium, and long-term clinical outcomes of patients undergoing MWA, comparing these results with existing literature on other treatment methods. Participants will continue their usual clinical care while data on their treatment and outcomes will be collected for analysis.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with small primary or secondary liver tumors or small kidney tumors that are not suitable for surgical resection.

Not a fit: Patients with extensive extrahepatic or extrarenal disease, or those with non-manageable coagulopathies, are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness of microwave ablation as a treatment option for patients with small renal and liver tumors.

How similar studies have performed: Other studies have shown promising results with microwave ablation for similar conditions, indicating that this approach is supported by existing evidence.
