[摘要] 目的：观察并总结131I-间碘苄胍(131I-MIBG)治疗恶性嗜铬细胞瘤转移灶的临床疗效。方法：我院1986年1月~2010年1月共收治94例恶性嗜铬细胞瘤转移的患者。按转移瘤大小将其分为三组，三组患者均每隔1~2个月静滴131I-MIBG 80~100 mCi，如果肿瘤组织接受辐照剂量达1 000 cGy/g以上，则每隔3~6个月治疗1次，每次80~100 mCi。结果：大部分患者症状消失，治疗总有效率达73.4%。131I-MIBG对于中小体积的肿瘤的治疗效果较好，与大体积肿瘤疗效比较，差异有统计学意义(χ2=143.19，P<0.05)。每克肿瘤组织接受辐照的剂量与其原始大小有密切关系。每克肿瘤组织接收剂量达1 500~2 000 cGy时，肿瘤可消失或明显缩小。结论：131I-MIBG对恶性嗜铬细胞瘤转移灶具有较好的疗效且副反应较小，不能行手术切除者可首选此方法治疗。

[Abstract] Objective: To observe and summarize the therapeutic effects of 131I-MIBG in treatment of m alignant pheochromocytoma with metastases. Methods: 94 patients of m alignant pheochromocytoma with metastases who were treated from January 1986 to January 2010 in our hospital were classified into 3 groups according to their tumor size. Intravenous infusion of 131I-MIBG 80-100 mCi was given every 1-2 months, or every 3-6 months if the absorption dose per gram of tumor was above 1 000 cGy. Results: Clinical symptoms disappeared in most patients after treatment, and the total effective rate was 73.4%. The effects in the small and medium volume groups were better than those in the large volume group (χ2=143.19, P<0.05). The absorption dose of tumor was closely related to its volume. When the absorption dose of tumor attained 1 500-2 000 cGy/g, the tumor was smaller or disappear obviously. Conclusion: 131I-MIBG has certain therapeutic effectiveness and low side effects in treatment of m alignant pheochromocytoma with metastases. Thus, treatment with 131I-MIBG should be the first selection for masses unable surgical resection.
