CT导向下^(125)I粒子植入治疗肝门区肝癌

CT guided radioactive seed ^(125)I implantation in treating hilar hepatic tumor and metastatic lymphnodes

目的评价CT导向下125I粒子植入治疗肝门区肝癌及淋巴结的临床价值。方法本组病例32例,其中肝门区肝细胞癌(HCC)8例,肝门区胆管癌(HC)12例,肝转移瘤6例,肝门区淋巴结转移6例。14例侵犯肝门胆管致肝内胆管扩张,22例合并肝硬化。全部病例经CT、MRI检查或病理穿刺活检证实。病灶平均直径为4.2 cm。采用TPS计算布源,在CT导向下将125I粒子植入瘤灶内,采用0.6~0.9 mCi活度的125I粒子相隔1.0~1.5 cm平面播植。结果2例死于远处转移,3例死于肝功能衰竭,全组中位生存时间10个月。2个月后CT复查,完全缓解(CR)2例;部分缓解(PR)20例;无变化(NC)5例;进展(PD)5例。总有效率(CR+PR)68.8%。2个月随访过程中发现7颗粒子在肝脏内游走,3颗粒子迁徙至肺内;1例出现气胸,肺压缩在30%以下,白细胞轻度下降1例。未见大出血、胆汁瘘、肠瘘、肠出血等严重并发症。结论CT导向下放射性粒子植入治疗肝门区肿瘤及淋巴结创伤小,并发症发生率低,生活质量改善明显,近期效果好,是治疗中晚期肝门区肿瘤及淋巴结的简单、安全、有效的方法。

Objective To investigate the clinical value of CT guided radioactive seed ^125Ⅰ implantation in treating hilar hepatic tumor and metastatic lymphnodes. Methods 32 patients with pancreatic cancer accepted CT guided radioactive seeds ^125Ⅰ implantation were enrolled in this study. The average tumor dimension was 4.2 cm. In this series, there were 8 cases of hepatocellular carcinoma, 12 cases of hilar cholangio carcinoma,6 cases of hepatic metastasis and 6 of hepatic hilar tumor and metastatic lymphnodes. Among these patients, 14 cases had cholangiectasis and 22 cases had cirrhosis. Under CT guidance, ^125Ⅰ seeds of 0.6-0.9 mCi were implanted into the pancreatic cancer at a distance of 1.0-1.5 cm according to TPS. Results Two cases died on account of metastasis and three died through liver function failure. Among CT followed-up of 32 patients in 2 months, 2 obtained CR, 20 obtained PR, 5 NC and 5 PD. The responsive rate was 68.8%. The side effects occurred during the procedure including pneumothorax in 1 case with lung compression less than 30% ; 7 seeds migration in liver and 3 seeds in lung. WBC decreased slightly in 1 cases during 2 months follow up. No massive bleeding, biliary fistula, intestinal fistula, intestinal hemorrhage, acute pancreatitis, enterorrhagia and intra-abdominal abscess were encountered. Conchlsions CT guided radioactive seed ^125Ⅰ implantation procedure is a safe and effective method in treating hilar hepatic tumor and metastatic lymphnodes with good clinical effects of minimal damage and few complications.
