153Sm-乙二胺四甲基撑膦酸治疗恶性肿瘤骨转移疼痛

目的 评价153Sm-乙二胺四甲基撑膦酸(153Sm-EDTMP)在恶性肿瘤骨转移疼痛治疗中的临床应用价值.方法 对80例骨转移癌患者进行153Sm-EDTMP治疗,按22.2～37 MBq/kg体重一次性静脉注射给药.按照视觉模拟评分法和Kamofsky评分标准,分别评价治疗前后患者疼痛缓解及生活质量改善情况.结果 153Sm-EDTMP治疗的80例骨转移癌患者中,疼痛缓解总有效率为68.75%.其中前列腺癌骨转移癌痛缓解率最高,达81.82%,其次为乳腺癌和肺癌,分别为80.00%、75.00%.分析治疗前后Karnofsky评分变化情况,发现疼痛级别越高生活质量改善越明显.结论 153Sm-EDTMP对恶性肿瘤骨转移所致的疼痛具有较好的缓解作用,对中、重度骨痛患者的生活质量有明显的改善,该法是使用放疗、镇痛药物等方法治疗骨转移癌痛的有益补充.

Evaluation of the dinical curative effect of using 153Sm-EDTMP in painful bone metastasis of malignant tumor

Objective To evaluate the clinical curative effect of using 153Sm-EDTMP in painful bone metastasis of malignant tumor. Methods Eighty patients with bone metastasis of malignant rumor underwent radionuclide bone palliation therapy were analysed.The treatment efficacy was evaluated by visual analogue scale (VAS) and Kamofsky performance scale.Results 68.75% of patients had a positive response.A better analgesic effect was found in cases of lung,prostate and breast carcinoma metastasm compared to metastasis from other malignant lesions.Improvement of performance in Karnofsky scale was found in cases of midrange and heavy range patients.Conclusion The analgesic effects of 153Sm-EDTMP is obvious in painful bone metastasis of malignant tumor.Improvement of life quality is significant in cases of midrange and heavy range patients.The therapeusis is a beneficial supplement of radiotherapy and odynolysis therapy.
