Initial results using radiofrequency interstitial thermal ablation (RITA) for the management of liver metastases

Background: hepatic metastases have been shown to be the major cause of morbidity and mortality in patients with gastrointestinal cancers and other malignant tumours. The liver is second only to lymph nodes as a common site of metastasis from solid cancers. Whilst hepatic resection remains the gold standard treatment for liver metastases, only 10–15% of liver-only solid tumour metastases are suitable for resection. Given that the majority of patients with metastatic hepatic malignancies are not candidates for surgical resection, this has led to the evaluation of an abundance of alternative approaches.
