The NPV was 92% and accuracy 93%. Median number of assessed lymph node stations during VAM(LA) was 4 (IQR 3–5), and in 96%, at least three stations were assessed.VAM(LA) has a satisfactory sensitivity of 73% to detect mediastinal nodal disease in cN1 lung cancer, and could be the technique of choice for pre-resection mediastinal lymph node assessment in this patient group with a one in four chance of occult-positive mediastinal nodes after negative PET-CT.Videomediastinoscopy reaches a sensitivity of 73% detecting N2 disease in cN1 NSCLC patients; N2 prevalence is 26% http://ow.ly/VrzL30gIOWm ER -
