1 Relationship between early recurrence and micrometastases in the lymph nodes of patients with stage I non-small-cell lung cancer  Riichiroh Maruyama, MDa, Kenji Sugio, MDa, Tetsuya Mitsudomi, MDb, Genkichi Saitoh, MDa, Teruyoshi Ishida, MDc, Keizo Sugimachi, MDa  The Journal of Thoracic and Cardiovascular Surgery  Volume 114, Issue 4, Pages (October 1997) DOI: /S (97) Copyright © 1997 Mosby, Inc.

2 Fig. 1 A, Section of the lymph node regional to primary lung adenocarcinoma. A single CK-positive tumor cell is seen against a background of benign lymph nodes cells by means of the strept-avidin-biotin complex immunoperoxidase technique with a monoclonal CK antibody and methyl-green counterstaining. B, A comparable section from the same lymph nodes as depicted in A, stained by HE. No tumor cells are visible in this routine preparation. (Original magnifications ×80.)

4 Fig. 2 A, The distribution of CK-positive tumor cells in the lymph nodes of T1 disease. B, The distribution of CK-positive tumor cells in the lymph nodes of T2 disease. The open squares indicate lymph nodes that were not examined, the hatched squares represent the CK-negative lymph nodes, and the closed squares denote the CK-positive lymph nodes. The numbers assigned to the regional nodal stations are as follows: number 1 indicates the highest mediastinal nodes, number 2 the paratracheal nodes, number 3 the pretracheal nodes, number 4 the tracheobronchial angle nodes, number 5 Botallo's nodes, number 6 the paraaortic (ascending aorta) nodes, number 7 the subcarinal nodes, number 8 the paraesophageal nodes, number 9 the pulmonary ligament nodes, number 10 the hilar nodes, number 11 the interlobar nodes, and number 12 the lobar nodes.28 The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /S (97) ) Copyright © 1997 Mosby, Inc.
