摘要: The objective of this paper is to report our results from a prospective study 167 patients with colorectal liver metastases treated radio-frequency ablation (RFA). Three hundred fifty-four treatments were performed in patients, 99 males, mean age 57 years (34–87). number was 4.1 (1–27). maximum diameter 3.9 cm (1–12). Fifty-one (31%) had stable/treated extra-hepatic disease. Treatments under general anaesthesia using US and CT guidance single or cluster water-cooled electrodes (Valleylab, Boulder, CO). All been rejected for refused surgical resection. Eighty percent received chemotherapy. Survival data stratified by tumour burden at the time first RFA. RFA 2.1 (1–7). During follow-up 17 months (0–89), 72 developed new 71 progressive There 14/354 (4%) major local complications 22/354 (6%) minor complications. For ≤5 metastases, no disease, 5-year survival diagnosis 30% thermal 26%. Given that operable median 32%, promising.
