Abstract:
Objective To compare positron emission tomography/computed tomography(PET/CT)vs.endobronchial ultra-sound-guided transbronchial needle aspiration(EBUS-TBNA)in evaluating lymph node metastasis in NSCLC.Methods We col-lected 79 NSCLC patients with enlarged mediastinal lymph nodes(diameter >1 cm by CT).The diagnostic values of PET/CT scanning and EBUS-TBNA for mediastinal staging were evaluated.Subgroup analysis according to histologic type was per-formed.Results There were 22 patients of N1 stage and 28 patients of N2 in these 79 cases.In the N1 patients,PET/CT's sen-sitivity and specificity was 59.1% and 75.4%,respectively.EBUS-TBNA's sensitivity and specificity was 86.4% and 100.0%,respectively.In the N2 patients,PET/CT's sensitivity and specificity was 67.9% and 76.5% and EBUS-TBNA's sensitivity and specificity was 89.3% and 100.0%.Conclusion EBUS-TBNA is more accurate than PET/CT in evaluating the metastatic condition of patients,and EBUS-TBNA can also benefit PET/CT(-)patients with adenocarcinoma.
