J Clin Oncol: s18 F. fluorodeoxyglucose positron emission tomography scan/computer tomography on the stages of head and neck cancer and negative predictive value and surgical effects on the N0 neck

The purpose of this study is to determine the negative prediction (NPV) of the clinical N0 neck based on the positive electron emission tomography (PET)/computertomic tomography (CT) on the basis of neck anatomyincluded participants in the newlydiagnosed, the first-time head and neck squamous cell carcinoma (HNSCC) and at least one clinical N0 neck side that planned an autopsyA total of 287 participants were forward-lookingly recruited from 23 American College of Radiological College imaging network qualification agenciesThe results of PET/CT were compared with those of neck anatomyresults, 212 participants had 270 Pet/CT scans and pathological results on the Neck Side of N0For visual evaluation, the NPV on the clinical-N0 side is 0.868 (95% CI, 0.803 to 0.925)For the maximum standardized intake values of the dicon method, the NPVs specificity of the nodule base is 0.940 (95% CI, 0.928 to 0.952) and 0.937 (95% CI, 0.925 to 0.949) at the pre-specified cutoff points of 2.5 and 3.5, respectivelyThe maximum standardized intake value for the best cutoff point was determined to be 1.8 and the NPV was 0.942 (95% CI, 0.930 to 0.953)Compared to PET/CT blind surgery, 51 (22%) of the 237 participants changed THE PET/CT informed surgical treatment regimenIn 34 participants (14%), this led to plans to dissect additional nodule levelsIn 12 participants (5%), this led to a decrease in the level of nodules planned for dissectionN0 neck PET/CT scan negative, 87% true negative, 13% false negativefluoro-deoxygenglucose-PET/CT has a higher NPV on the N0 neck of T2 to T4 HNSCCAbout 22% of patients in this group can change surgical treatment regimens based on PET/CT results These results show that the s/he-fluoro-oxycodone glucose-PET/CT can help clinicians determine the best treatment option for The N0 Neck of HNSCC clinically A well-designed clinical trial should be conducted to test the results of a neck anatomy that uses PET/CT to omit
