- Brief Summary
Ablation has been an effective therapy in treating intrathoracic metastases. However, for hepatocellular carcinoma with pulmonary oligometastasis, ablation of metastases remains relatively unexplored and still needs clinical evidence.
- Detailed Description
Systemic therapy is the standard treatment for advanced hepatocellular carcinoma (HCC) with metastasis. However, metastases with limited number (oligometastasis) can represent a subtype and transition point between localized disease and widespread metastases. Thus, eliminating metastases could be advantageous and beneficial to the prognosis if feasible and permitted. Image-guided ablation therapy, such as microwave ablation (MWA), radiofrequency ablation (RFA), and cryoablation, has attracted great interest as a minimally invasive approach against intrathoracic metastases. Recently, ablation has been used on patients with pulmonary metastases from various cancers. This technique yields high proportions of sustained complete responses and is associated with relatively low morbidity. This multicenter study focuses on the management of ablation of oligometastasis therapy combined with systemic therapy.

- Primary Outcome Measures
Name Time Method Progression-Free-Survival 12 months Progression was defined as progressive disease by independent radiologic review
- Secondary Outcome Measures
Name Time Method Overall survival (OS) 24 months OS is the length of time from the date of inclusion until death from any cause.
Objective response rate (ORR) 12 months ORR, as determined based on tumor response according to RECIST 1.1, is defined as the proportion of all included patients whose best overall response is either a complete response or partial response.
