【摘要】 目的 :了解乳腺癌骨转移的特点。方法 :通过对 93例乳腺癌骨转移患者的骨扫描结果进行回顾性分析 ,了解乳腺癌骨转移的特点。结果 :乳腺癌患者骨转移表现以异常放射性浓集灶为主 ,部分患者也可表现为放射性稀疏缺损区。骨转移病灶以脊柱及肋骨为最多 ,占 80 % ;颅骨、胸骨、骨盆及四肢骨约占 2 0 %。浸润性导管癌最多 ,占 3 5 5 % ;腺癌其次 ,占 2 5 8% ;髓样癌占 12 9% ;黏液癌仅占 4 3 %。结论 :乳腺癌患者骨转移表现以异常放射性浓集灶为主 ,部分患者也可表现为放射性稀疏缺损区 ;浸润性导管癌和腺癌骨转移率高于髓样癌和黏液癌更多还原

【Abstract】 OBJECTIVE:To find out characteristics about bone metastasis of breast cancer.METHODS:The bone scaning was performed in 93 patients with breast cancer,and the characteristics about bone metastasis of breast cancer were analysed.RESULTS: Most of patients′imaging showed high radiotracer uptake in bone metastasis,parts of patients′ imaging showed radiotracer absence. Eighty percent of all metastasis were in spine and ribs and about 20% in skull,sternum,pelvis and limbs,and 35.5% of patients were invasive ductal carcinoma, 25.8% adenocarcinoma, 12.9% medullary carcinoma and 4.3% mucoid carcinoma.CONCLUSIONS: Bone metastasis of breast cancer shows mainly high radiotracer uptake in bone scaning,it in parts of patients shows radiotracer absence.The rates of bone metastasis of invasive ductal carcinoma and adenocarcinoma are higher than those of medullary carcinoma and mucoid carcinoma.更多还原
