- 目的:探讨动脉灌注吉西他滨联合125I粒子植入治疗进展期胰腺癌的临床价值。Objective:To study the role of 125I implantation plus gemcitabine in treatment of advanced pancreatic cancer(APC).
- 用Iodogen法125I标记的猪脾转移因子示踪液灌注大白鼠后，于不同时间，分别测定血、肝脏及尿标本中放射活性（cpm值），上述各标本中cpm值到达高峰时间依次为2h、8h及24h。The radioactivities (cpm) of specimens of blood, liver and urine of white rats were detected at different time after being perfused with porcine spleen transfer factor labelled with 125I by Iodogen method. The result showed that the times when the cpm of specimens described above reached peak value were 2, 8 and 24hours, respectively.
- 方法:43例进展期胰腺癌(APC)患者随机分成125I粒子植入+吉西他滨(GEM)治疗组(A组,n=18)和单纯吉西他滨化疗组(B组,n=25)。Methods: Fortythree untreated patients with APC were randomly divided into two groups: 125I plus gemcitabine(group A,n=18)and Gemcitabine(group B,n=25).
- 复查病例均未发现放射性肺炎及骨髓抑制等严重并发症。 结论CT导向下放射性125I粒子组织间植入治疗肺癌安全有效,并发症少,值得推广。CONCLUSION : CT Guided Radioactive 125I seeds Interstitial Implantation is a safe ,effective method with little side effects and worth spread .
