ABSTRACT
Objective To summarize that the distant interval metastasis of nasopharyngeal carcinoma(NPC) patients who have been examined by 18F-FDG PET/CT and analysis the diagnostic efficacy of doctors using PET/CT device.Methods 75 patients were divided into three groups including primary patients without any treatment and patients in treating and patients after radiotherapied.The distant interval metastasis sits,incidence and their difference were analyzed.We adopt five grades to diagnose distant interval metastasis of NPC.And we choose the difference grade as cut off point to draw ROC curve and then decide the best diagnostic cut off point.Result There are 22patients in the first group and 2patients in the second group and 51patients in the third group in all 75paients.The incidence of distant interval metastasis in the first group is 59.1% and third 68.6% and there are statistical significance between groups(P=0.0001).The most frequent sites of distant interval metastasis is the distant interval lymph nodes(38.67%) and the second is skeleton(36%) and the third is liver(25.33%).ROC curve indicate that third one is the best cut off point because of doctors using PET/CT device can acquire the optimal sensitivity(86.36%)and specificity(88.24%) and accuracy(76.8%).Conclusion The incidence of distant interval metastasis is higher and the most frequent part is distant interval lymph nodes.And the doctors using PET/CT device diagnose the distant interval metastasis of NPC efficacy is higher.
