158例食管癌骨转移核素骨显像特征分析

Radionuclide Bone Imaging Features of Bone Metastasis from 158 Patients of Esophageal Cancer

目的探讨食管癌骨转移患者的核素骨显像特征及临床应用。方法收集我院2007年1月至2011年12月接受全身骨显像的158例食管癌患者病历资料。对全身骨显像结果进行统计和分析,归纳食管癌患者骨转移显像特点。结果 158例食管癌患者骨转移发生率为17.72%(28/158),其中以脊柱及肋骨转移最为多见,发生率分别为89.29%(25/28),64.29%(18/28)。依据病理类型,鳞癌、腺癌、小细胞癌的骨转移发生率分别为13.83%(13/94),21.95%(9/41)和26.09%(6/23)。结论放射性核素骨显像对食管癌患者具有重要的临床意义,应作为治疗前后骨转移诊断和随访的常规检查手段。

Objective To investigate radionuclide bone imaging features and its clinical value in esophageal cancer patients with bone metastasis.Methods The medical records of 158 patients with esophageal cancer who accepted the whole body bone scan（WBS） from January 2007 to December 2011 in our hospital were collected.The WBS results were statistically analyzed,and the imaging features were summarized.Results The bone metastasis incidence of 158 cases of esophageal cancer patients was 17.72%（28/158）.The spine and rib metastasis were the most common,the rate was 89.29%（25/28） and 64.29%（18/28）,respectively.According to the pathological type,the bone metastasis incidence of squamous cell carcinoma,adenocarcinoma,small cell carcinoma was 13.83%（13/94）,21.95%（9/41） and 26.09%（6/23）,respectively.Conclusion Radionuclide bone imaging has important clinical value in patients with esophageal cancer.It should serve as a routine means of diagnosis and follow-up of bone metastases before or after treatment of patients.
