The Lymphatic Spread of Lung Cancer: An Investigation of the Anatomy of the Lymphatic Drainage of the Lungs and Preoperative Mediastinal Staging.

The knowledge of lymphatic spread of lung cancer permitted the study of anatomy of lymphatic drainage of the lungs. The history of anatomy of lymphatic drainage of the lungs began in the 15th century. In the human, pulmonary lymph flows to the lymph nodes around the lobar bronchi and thence to extrapulmonary lymph nodes located around the main bronchi and trachea and its bifurcation (tracheobronchial lymph nodes). These send their efferents to a right and left mediastinal lymph trunks, which may join the thoracic duct, but usually drain opening directly into the brachiocephalic vein of their own side.

Guiding Principles on the Importance of Thoracic Surgical Education on Establishing Integrated Thoracic Surgery Program, Interdisciplinary Thoracic Oncology Conferences, and an Interdisciplinary Approach to Management of Thoracic Malignancies.

The objective of these notes is to stress the principles underlying the management of primary lung cancers and other types of malignancies in the thorax-diffuse malignant mesothelioma, invasive mediastinal tumors, chest wall sarcoma, and tracheal neoplasms-and from these considerations to outline a routine scheme for management, which can be followed easily by all staff. It is hoped that by adherence to this routine, adequate and efficient management of all cases will be obtained, both in the very important matter of preoperative preparation, as well in the postoperative management.
