摘要
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 evaluate the palliative effect in patients with osseous metastases.Methods:120patients with bony metastases were recruited.They were divided into three arms:A,B and C.Each arm had40patients.A arm received local field radiotherapy;B arm received local field radiotherapy and stron-tium-89,and C arm received internal strontium-89radiotherapy.Results:The pain alleviation and the im-provement of SPECT imaging in patients of B arm were better than that in A and C arm.The new sites of bone pain appeared fewer(P<0.05).The hematological toxicity in the three groups was not significantly differ-ent(P>0.05).Conclusion:Stronuium-89adjuvant to local field radiotherapy is very useful for patients with malignant cancer metastasas in the bone.
