CT导向下经皮肺穿刺瘤体内植入125I粒子治疗老年肺癌的可行性研究

目的 探讨CT导向下经皮肺穿刺瘤体内植入125I粒子治疗老年肺癌的临床价值.方法 46例老年肺癌患者,CT导向下经皮肺穿刺肿瘤内植入125I粒子,术后1、2、3、6个月,观察肿瘤大小的变化判断临床疗效.结果 46例患者,57个病灶,其中7例行2次植入,1例行3次植入,总穿刺次数为76次.术后观察6个月.术后1、2、3、6个月肿瘤治疗有效率(CR+PR)分别为8.77%(5/57)、40.35%(23/57)、89.47%(51/57)、96.49%(55/57).并发气胸6.58%(5/76),咳血19.57%(9/46).于植入后第6个月复查时2例出现粒子丢失,可能是肿瘤缩小,粒子被咳出.结论 CT导向下经皮肺穿刺瘤体内植入125I粒子对老年肺癌患者是一种微创、安全、疗效可靠的治疗手段.

Brachytherapy by CT-guided Percutaneous Paracentesis Implantation of Iodine-125 Seed for Lung Cancer in Old Patients

Objective To observe the efficiency and safety of brachytherapy by CT-guided percutaneous paracentesis implantationof iodine-125 seed for lung cancer in elder patients.Methods 46 elder patients with lung cancer(65~81 years)were undergonebrachytherapy by CT-guided percutanepus paracentesis implantation of iodine-125 seeds with implanting needle(18-gauge). The effect of treatment according to observe the changes of tumors in size was evaluated after operation 1,2,3 and 6 months,respectively. Results There were totally 57 lesions in 46 cases,7 cases were undergone two times of implantation,and 1 case was undergone three times of implantation,totally the puncture accounted for 76. The effective rate (CR+PR) of treatment after one ,two, three, and six months was 8.77%(5/57), 40.35%(23/57),89.47%(51/57) and 96.49%(55/57),respectively. 5 patients(6.58%) accompanied by pneumathorax.Conclusion Brachytherapy by CT-guided percutaneous paracentesis implantation of iodine-125 seed is a safe, reliable and effective treatment for lung cancer, especially for elder patients.
