50例鼻咽癌患者核素骨显像分析

目的 分析鼻咽癌患者全身骨放射性核素显像。探讨骨转移的发生概率及好发转移部位。方法 50例鼻咽癌患者行全身骨放射性核素显像，骨显像剂为^99m锝-亚甲基二磷酸盐（^99mTcMDP)。结果 50例鼻咽癌患者核素骨显像示骨转移32人，其中鳞癌31人，未分化癌1人，鼻咽癌骨转移部位以脊柱，骨盆多见，肋骨，四肢，头颅次之。结论 鼻咽癌患者核素骨显像对鼻咽癌的诊断及治疗方案选择和预后均有重要的临床参考价值。

Clinical assessment of radionudide bone scanning in 50 patients with nasopharyngeal carcinoma

Objective It' s an evaluation of radionuclide bone scan in detecting bone metastases in the pa-tients with the nasopharyngeal carc inoma.The ratio of bone metastases a nd the locations commonly involved w ere also investigated.Method The 99m Tc -MDP bone scan was performed in 50p atients with nasopharyngeal carcin oma.Result Bone metastases was revealed in 32patients out of 50,including 32squamo us cell carcinoma and 1undif-ferentiated carcinoma.The metasta ses occurred in vertebral column,rib,pelvis,extremities,and skull in90.6%,56.3%,59.4%,43.8%,and 28.1%patie nts respectively.Conclusion Radionuclide bone scan is helpful in diagnosis,prognosing and treatmen t designing of nasopharyngeal carcinoma.
