消化道肿瘤核素骨显像特点分析

Characteristic analysis of bone scan in patients with carcinoma of alimentary tract

目的探讨消化系统恶性肿瘤骨转移的概率和转移灶的分布特点。方法对136例消化系统恶性肿瘤99mTc-MDP全身骨显像进行回顾性分析。结果消化系统恶性肿瘤的骨转移率为63.9%,食管癌和肝癌骨转移率最高,达66.7%,其次为直肠癌(60.0%)、胃癌(38.9%)。转移灶分布以胸部最常见,占总病灶的37.8%,其次为脊柱(30.1%)、四肢(14.8%)、骨盆(14.0%)和颅骨(3.2%)。结论消化系统恶性肿瘤患者早期或定期进行骨显像是必要的。

Objective Toanalysis the characteristics of radionuclide bone scan for detecting bone metastasis in patients with carcinoma of alimentary tract. Methods One hundred and thirty-six patients with carcinoma of alimentary tract were examined of bone scintigraphy in SPECT after injection of ^99mTc-MDP. Results Of 136 patients, hone metastases were detected in 87 patients, 40 （66.7%）patients with esophageal cancer, 24（66.7%） patients with hepatic cancer, 24（60%） patients with rectum-anal cancer, 7 （38.9%） patients with gastric cancer, the more metastases lesions were in thoracic, vertebral column, femur, pelvisl. Conclusion The bone metastasis is more common in patients with digestive cancer, radionuclide bone imaging is necessary to the therapy for the patients with carcinoma of alimentary tract.
