According to current scientific investigations radiofrequency ablation (RFA) as a local ablative tumor therapy for unresectable liver malignancies is currently accepted as the best therapeutic choice. The results of randomized trials justify RFA for small hepatocellular carcinomas (HCC) and RFA is considered to be a viable alternative to resection for inoperable patients with limited hepatic metastatic disease, especially from colorectal cancer (CRC LM). However, surgical resection still remains the gold standard for resectable CRC LM. The intraprocedural image guidance modality of choice is computed tomography (CT) alongside CT fluoroscopy. Contrast-enhanced ultrasound (CEUS) and magnetic resonance imaging (MRI) are used for preprocedural lesion detection and differentiation as well as for follow-up and can be used to perform RFA procedures as well. This article highlights new developments in RFA.
根据目前的科学研究，射频消融术（RFA）作为一种用于不可切除肝脏恶性肿瘤的局部消融肿瘤治疗方法，目前被认为是最佳治疗选择。随机试验结果证明RFA适用于小肝细胞癌（HCC），并且对于患有局限性肝转移疾病（尤其是结直肠癌肝转移（CRC LM））的无法手术的患者，RFA被认为是一种可行的手术替代方案。然而，手术切除仍然是可切除CRC LM的金标准。术中首选的图像引导方式是计算机断层扫描（CT）以及CT透视。对比增强超声（CEUS）和磁共振成像（MRI）用于术前病变检测和鉴别以及随访，也可用于进行RFA手术。本文重点介绍了RFA的新进展。
