目的 评估集束电极射频 (radiofrequency ,RF)治疗肝癌的临床疗效及适应证。方法回顾分析我院 2 45例肝癌患者经集束电极射频治疗的临床资料 ,比较治疗前后癌体内血液供应状况 ,癌灶体积 ,胎甲球蛋白 (AFP)的变化 ,及患者自觉症状的改善情况。结果 AFP术后 1周内下降者占5 0 % ,患者自觉症状明显改善。癌灶直径小于 5cm的肝癌 ,术后 1至 6个月内 70 %～ 90 %癌灶血液供应消失 ,癌灶缩小 ,甚至消失。个别癌灶复发经再次射频治疗得到控制。直径大于 5cm的肝癌 ,配合介入栓塞治疗 ,6 0 %癌灶缩小。继发性肝癌 ,就癌灶而言 ,射频治疗术后癌灶缩小 ,症状得到控制。结论 B型超声引导下集束电极射频治疗肝癌近期疗效确切。直径小于 5cm的癌灶疗效理想 ,直径大于 5cm的肝癌 ,采用多点射频治疗 ,再配合介入栓塞治疗 ,也取得了比较理想的疗效。
Objective To evaluate the clinical efficacy and indications of radiofrequency (RF) therapy for liver cancer. Methods A retrospective analysis was performed on the clinical data of 2 45 cases of HCC patients treated by RFE. The changes of blood supply, tumor volume, fetal AFP, and the improvement of patients’ symptoms were compared before and after treatment. Results AFP decreased within 1 week after surgery accounted for 50%, patients with symptoms improved significantly. Focal liver cancer less than 5cm in diameter, within 1 to 6 months after surgery, 70% to 90% of the foci of blood supply disappears, the foci shrink or even disappear. The recurrence of individual cancer was controlled by RF therapy again. Liver cancer more than 5cm in diameter, with interventional embolization, 60% foci shrink. Secondary liver cancer, in terms of cancer, radiofrequency treatment of cancer shrinkage, the symptoms under control. Conclusion B-ultrasound-guided bundled electrode radiofrequency treatment of liver cancer has the exact effect in the near future. The diameter of less than 5cm of the foci of curative effect ideal, diameter greater than 5cm of liver cancer, multi-point radiofrequency treatment, coupled with interventional embolization, but also achieved a more ideal effect.
