504例体部恶性实体瘤患者金标植入的探讨

目的 探讨体部恶性实体肿瘤实施射波刀治疗前肿瘤靶区金标植入术的技术要点、效果及并发症。方法 504例体部实体恶性肿瘤患者在CT引导下行射波刀治疗前肿瘤靶区金标植入术，观察植入效果及并发症。结果 504例接受金标植入的患者中，500例（99.2％）植入成功。453例肝脏穿刺患者中，6例出现金标游走。158例出现穿刺部位疼痛，3例出现心动过速，肝脏穿刺针道少量出血致术后腹痛33例；19例肺脏穿刺患者中，1例出现少量气胸，1例出现少量血胸。结论 体部恶性实体肿瘤实施射波刀治疗前肿瘤靶区金标植入术是一种微创且相对比较安全的方法。

Experience on the implementation of fiducial markers for 504 patients with body malignant tumors

Objective To investigate technical points, effect and complications of fiducial implantation for body malignant solid tumors with cyberknife. Methods A total of 504 cases of body malignant solid tumors accepted fiducial implantation under CT guidance before the treatment of cyberknife. The complications and effect were observed. Results Among the 504 cases, the success- ful rate of fiducial implantation was 99. 2% （500/504）. Among the 453 patients with liver nidi, 6 had fiducial migration. One hundred and fifty-eight patients felt pain at the punctured sites and 3 patients bad tachycardia. Among the 19 lung cancer patients who accepted paracentesis, 1 case had haemothorax and 1 case got pneumothorax. Conclusion The method of fiducial implantation on targets before treating malignant solid tumor with cyberknife is minimally invasive and comparatively safe.
