#12u nodes are peribronchial lymph nodes around the upper lobe bronchus which should not be routinely dissected in cases with middle lobe carcinoma or lower lobe carcinoma. In this paper, #12u were examined histologically in 152 lung cancer cases. As a results, 14 of 152 (9.2%) had nodal diseases in #12 nodes. #12u nodes were involved in 3 of 30 N1 diseases (10%), and in 11 of 35 N2 diseases (31.4%). There was a case which had no nodal involvement except for #12u node. And in three cases, we found only one nodal metastasis except for #12u nodes. If we did not dissect #12u nodes, these cases will be relapse in near future. Thus, for curative operation, #12u nodes should be dissected as a standard operation.
