Intrathoracic neoplasia can take several forms including primary or metastatic lung tumors, cranial mediastinal neoplasms, mesothelioma (which can affect the pericardium and pleural surfaces) and less common primary or metastatic cardiac neoplasms. In all of these cases appropriate staging of the disease should involve diagnostic imaging as well as sampling of the any draining lymph nodes.
In the case of lung tumors it is known that there is a significant negative prognostic effect on survival for dogs with primary lung tumors that have evidence of metastatic disease to the tracheobronchial lymph nodes compared to those without.1-3 It is therefore currently recommended that dogs undergoing lung lobectomy for resection of primary lung tumors also undergo sampling or excision of the draining tracheobronchial lymph nodes (TBLN) to assess for metastatic disease. Pulmonary lymphatics drain into three groups of tracheobronchial lymph nodes located around the tracheal bifurcation. These lymph nodes are the primary site of lymphatic metastasis for pulmonary neoplasms. The right node lies just caudal to the insertion of the azygous vein into the cranial vena cava and is sometimes somewhat obscured by the base of the right cranial lung lobe. However, the right node may be the easiest node to dissect. The left TBLN lies just ventral to the aorta on the left side and is somewhat more challenging to dissect. The central TBLN is generally bilobed with a narrow isthmus connecting both sides. It is accessible from the right side but not the left side and is ventral to the azygous vein, more caudal to the right node and just dorsal to the caudal lobar bronchus. Sternal and mediastinal lymph nodes are sometimes also accessed for thoracoscopic resection if pre-operative diagnostic imaging is suggestive of these lymph nodes being abnormal. The author has removed a number of sternal nodes in dogs and this is a reasonably straightforward procedure. [...]
