120例乳腺癌术后核素骨显像与病理结果分析

Clinical Assessment of Bone Scanning in Breast Cancer Patients after Mastectomy

目的:对不同病理类型乳腺癌术后患者行全身核素骨显像,以观察骨转移的发生率及转移部位。方法:对12 0例乳腺癌患者术后进行骨显像,显像剂为99m TC- MDP。结果:112 0例乳腺癌患者核素骨显像示转移者4 9例,阳性率为4 0 .8% ;2不同病理类型乳腺癌中以低分化腺癌骨转移最高,与其他病理类型骨转移发生率差异有显著性;3术前发生腋淋巴结转移者有5 8.8%骨显像阳性,与术前未发生腋淋巴结转移患者相比差异有显著性;4乳腺癌转移部位以肋骨为最多见(33.6 % ) ,其次为脊柱(2 0 .5 % )。结论:乳腺癌患者检查骨显像对乳腺癌的预后评估及不同病理类型的治疗方案选择有重要的临床参考价值。

Objective To evaluate radionuclide bone scanning in patients with breast cancer for detecting bone metastasis.Methods 120 patients with breast cancer underwent bone scanning with r-camera(GZB) after injection of 99m TC-MDP ients,bone metastase ra(GZB).Results Of 120 patients,bone metastase were detected in 49 patients. Among these bone imaging positive patients,58.8 % showed axillary tymph node metastases before operation.When compared with patients without lymph node metastases before operation the difference is of marked statistical significance (P<0.01).The metastases detected in rib .vertebral, column.Conclusions Radionuclide bone imaging is useful for staging ,treating and prognosis of breast canacer.
