目的 探讨 12 5I永久性植入组织间治疗不能切除的胰腺癌的疗效。方法 选择晚期胰腺癌病人 12例。将12 5I粒子永久性植入癌组织区域和癌细胞转移途径的各组 (站 )淋巴结区域。术后 3～ 7d测血象及免疫指标 ,1周后摄X片观察12 5I分布状况 ,观察有效率。结果 有效率41.67% ,病人的平均生存时间为 9.66个月 ,其中 1例已经存活 2 5个月 ,无一例出现因植入12 5I粒子而导致的严重并发症。结论 组织间永久性植入12 5I粒子治疗恶性肿瘤方法简单、安全、有效
Objective To investigate the curative effect of 125I permanent implantation in the treatment of unresectable pancreatic cancer. Methods Select patients with advanced pancreatic cancer in 12 cases. 125I particles were permanently implanted into each of the groups (stations) of the lymph node area of the cancer tissue and cancer metastasis. After 3 ~ 7d, blood test and immune index were taken. One week later, X-ray was taken to observe the distribution of 125I, and the effective rate was observed. Results The effective rate was 41.67%. The mean survival time of patients was 9.66 months. One of them had survived for 25 months. None of the patients had severe complications due to 125I seeds implantation. Conclusion The method of permanent implantation of 125I particles in the treatment of malignant tumors is simple, safe and effective
