放射性核素淋巴扫描在恶性肿瘤诊治中的临床应用

Clinical application of radionuclide lymphoscintigraphy in malignant tumor

目的:探讨放射性核素淋巴扫描在恶性肿瘤诊治中的临床价值。方法:对76例恶性肿瘤患者进行盆腹腔放射性核素淋巴扫描,双足I、II趾间皮下或肛周粘膜下注射99mTc-DX(右旋醣酐)74～111MBq?0.1～0.2ml,于1小时后行双下肢及盆腹腔显像,部分患者行3小时延迟显像。结果:76例患者中41例盆腹腔淋巴结核素分布异常,其中42例与手术病理对照,32例核素淋巴显像结果与病理诊断一致,诊断符合率为76.2%。结论:核素淋巴显像在恶性肿瘤淋巴转移的定位、定性诊断中有一定的价值。

Objective:To study the value of radionuclide lymphoscintigraphy for malignant tumor.Methods:Lym-phoscintigraphy was performed in76patients with malignant tumor.This method consisted of injecting74～111MBq?0.1～0.2ml 99m Tc-dextran into the toe web or anal submucosa.Pelvic lymphoscintigraphy was performed after1hour or 3hours.Results:The abnormity of nodal uptake of radionuclide on pelvic scanning was seen in41patients.42patients were confirmed by op-eration and pathology.Diagnosis-coincidence rate was76.2%.Conclusion:This study shows better clinical value in the staging of tumor.
