目的:分析局部外照射配合89 Sr治疗骨转移癌的疗效。方法:120例确诊为骨转移癌的患者,分为3组,每组40例。局部外照射(A组),局部外照射+89 Sr治疗(B组),89 Sr治疗(C组)。结果:治疗后B组骨痛缓解,骨显像显示原发灶改善明显好于A组、C组,新疼痛部位的出现少于A组、C组(P<0.05),治疗后血液学的毒性3组差异无显著性(P>0.05)。结论:局部外照射配合89 Sr治疗骨转移癌有较好的疗效。
Objective: To analyze the effect of local external irradiation combined with 89 Sr in the treatment of bone metastases. Methods: One hundred and twenty patients with bone metastases were divided into three groups, 40 cases in each group. Local external beam irradiation (group A), local external irradiation +89 Sr treatment (group B), 89 Sr treatment (group C). Results: After treatment, bone pain was relieved in group B, and bone imaging showed that the improvement of primary lesions was significantly better than that of group A and group C. The occurrence of new pain sites was less than that of group A and group C (P <0.05) There was no significant difference in toxicity between the three groups (P> 0.05). Conclusion: Local external irradiation combined with 89 Sr treatment of bone metastases have a good effect.
