DATA SOURCES Published randomized controlled trials of CH vs SH with a minimum clinical follow-up of 12 months were searched and selected in the MEDLINE, EMBASE, and(More)
Ablation of liver tissue produces in situ tumoural antigens and elicits specific immune responses. The aim of this review is to examine the available data about the local and systemic responses produced and to compare differences between the methods available. A literature search was undertaken for all papers focusing on immune responses following ablative(More)
This article reviews the therapeutic efficacy and complications of microwave ablation (MWA) in the treatment of primary and secondary liver malignancies. A PubMed search using keywords 'microwave', 'liver', 'malignancy', 'cancer' and 'tumour' was performed to identify articles related to MWA of liver malignancies published in English from 1975 to February(More)
