147例肺癌核素骨显像结果分析

目的探讨肺癌骨转移患者骨显像的特点及规律。方法对147例肺癌患者静脉注射99mTc-MDP,3～4h后行全身骨显像。结果147例肺癌患者中骨转移阳性者73例,阳性率为49.7%。其中肺腺癌的阳性率为62.9%,肺鳞癌的阳性率为38.9%,两者骨转移阳性率之间有显著统计学差异(P<0.01)。骨转移的部位以胸部为多见,其次为脊柱、骨盆、肢体和颅骨。结论核素骨显像对于探查肺癌骨转移瘤有很高的灵敏度,肺腺癌较鳞癌易发生骨转移,骨转移的部位以胸部为多见。

Clinical Assessment of Radionuclide Bone Imaging in 147 Patients with Lung Cancer

Objective To evaluate the characteristics of bone metastases in lung cancer.Methods 147 patients with lung cancer underwent whole body bone imaging after injection of 99mTc-MDP.Results Of 147 patients,bone metastases were detected in 73 patients,the incidence of bone metastasas was 49.7%,adenocarcinoma was 62.9%,squamous carcinoma was 38.9%,there was significant difference between the two groups(P<0.01).The site of bone metastases was commonly seen in the thorax,followed by spine,pelvis,limbs and skull.Conclusion With high sensitivity in early detection of bone metastases,the incidence of bone metastasas of adenocarcinoma was higher than squamous carcinoma in patients with lung cancer,The site of bone metastases was commonly seen in the thorax.
