为明确乳腺癌骨性胸廓转移特点及规律,本研究收集了72例未经骨转移治疗的乳腺癌骨性胸廓转移的多层螺旋CT(MDCT)表现,回顾分析骨性胸廓转移的优势解剖分布及转移类型。结果发现转移灶以胸椎最多见,左侧第4肋骨是肋骨转移最多受累部位,右乳癌患者更易出现双侧肋骨转移(65%)及双侧上肢带骨(54.5%)转移;28例患者表现为溶骨转移(38.9%),30例发生成骨转移(41.7%),转移类型中以成骨转移为主;乳腺癌骨性胸廓转移存在一定的规律及特点。
In order to clarify the characteristics and regularity of bony metastasis of breast cancer, we collected 72 cases of breast cancer without bone metastasis by multi-slice spiral CT (MDCT) manifestations, retrospective analysis of the dominant anatomical distribution of bony thoracic metastasis And transfer type. The results showed that the most common metastases were thoracic vertebrae. The fourth rib on the left was the most affected site of rib metastasis. The patients with right breast cancer were more likely to have bilateral rib metastases (65%) and bilateral upper extremity bone metastases (54.5%). Osteolytic metastasis (38.9%), osteogenesis metastasis (41.7%) in 30 cases and osteogenic metastasis in metastatic type. There are some regularities and characteristics of bony thoracic metastasis in breast cancer.
