Radiofrequency ablation (RFA)
Killing a tumour by heating it with an electrical current through a needle placed under image guidance, without removing it.
A probe delivers alternating current that heats tissue above 60°C, coagulating tumours up to about 3 cm. Standard for small hepatocellular carcinomas (equivalent to resection under 2-3 cm), colorectal liver metastases, small kidney tumours in comorbid patients, lung nodules, and Barrett's oesophagus after endoscopic resection. Limitations are the heat-sink effect near large vessels and incomplete ablation of larger lesions, which microwave ablation partly overcomes.
