This study was conducted to investigate this issue.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective analysis was conducted at the Chinese Academy of Medical Sciences. Patients undergoing right middle and lower lobectomy with lymphadenectomy for preoperative clinical stage Ia\u2013IIIa from 2014 to 2015 were identified. To avoid interference, cases were limited to tumors within the primary lobe. When a tumor is completely located in the lower lobe, no direct invasion occurs into the visceral pleura\/bronchus\/parenchyma of the middle lobe and tumor cell metastasis into the peripheral LNs (stations 12\u201314) in the middle lobe is defined as cross\u2010lobe lymph node metastasis (CLM).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 68 patients were identified, of which nine (13.2%) had CLM. Seven had squamous cell carcinoma, one adenocarcinoma, and one small cell carcinoma. Seven cases (77.8%) had intermediate bronchus invasion, and seven cases (77.8%) intermediate bronchus adjacent lymph node involvement (station 11). Compared to non\u2010CLM patients, tumor diameter (5.2 vs. 3.2; <jats:italic>P<\/jats:italic>\u2009=\u20090.28), N2 lymph node metastasis rate (66.7% vs. 28.8%; <jats:italic>P<\/jats:italic>
