However, the early pathological stage was identified as the only factor independently associated with recurrence\u2010free survival by multivariate analysis (<jats:italic>P<\/jats:italic>\u2009=\u20090.038). In a preoperative lymph nodes evaluation, the accuracy and specificity of computed tomography alone were 52.9% (46\/87) and 88% (302\/343), respectively, and 73.2% of these cases with incorrect nodal staging (30\/41) were upstaged. Skipping metastases were more frequent in operated stage N2 cases (71.4%), whereas whether or not those patients showed skipping metastasis did not affect their recurrence\u2010free survival or overall survival (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). The highest metastasis frequencies for specific lobes with primary lymphoepithelioma\u2010like carcinoma are as follows: #5 left upper lobe (21.4%); #7 left lower lobe (40.7%); #2R (28.6%) and\/or #4R (14.3%) right upper lobe; #7 (42.9%) right lower lobe; #7 (28%) and\/or superior mediastinal nodes (36%) right middle
