^(18)氟-氟化脱氧葡萄糖在下咽部肿瘤诊断中的作用

The role of ^(18)F-FDG in hypopharyngeal cancer

目的 :研究18氟 氟化脱氧葡萄糖 ( 18F FDG)在下咽部肿瘤诊断中的作用。方法 :2 0例下咽部肿瘤患者均接受18F FDG检查及CT、全组内镜 (食管、咽喉、气管镜 )检查。结果 :2 0例下咽部肿瘤患者18F FDG检查结果显示 :2例阴性 ;18例肿瘤原发部位有同位素浓集 ,其中 5例伴异位同位素浓集。对此 5例患者进一步临床、病理检查证实 :1例食管部占位 ,2例肺部病变 ,2例为良性改变。18F FDG检查结果显示的病变范围与CT、内镜检查相符。结论 :18F FDG检查可以提高下咽部肿瘤、尤其是隐匿的并发肿瘤诊断的准确性 ,明确病变范围 ,为临床治疗提供依据 ;同时又是一个简单、易行的下咽部肿瘤的随访检查手段。

Objective:To evaluate the function of fluorine 18 fluorodeoxyglucose ( 18 F FDG) in the diagnose of hypopharyngeal cancer.Method:Twenty patients with hypopharyngeal cancer were entered in the research. Every clinical information was collected carefully, including 18 F FDG , CT scanner and panendoscopy (pharyngo laryngo broncho oesophagien), compared and analysed with each other.Result:The study showed 18 positive 18 F FDG reactions among these 20 patients, including 5 ectopia reactions. Compared with the clinical and pathology exam, we found that 18 F FDG exam had a good correspondance, with such good sensitivity and specificity.Conclusion: 18 F FDG reaction is useful in the diagnose of hypopharyngeal cancer , especially for the detection of the secondary secret cancer; also useful for the follow up exam.
