Value of anterior mediastinotomy in bronchogenic carcinoma of the left upper lobe
TE Bowen, R Zajtchuk, DC Green and WH Brott
Neoplasms of the left upper lobe may spread directly to the anterior
mediastinal group of nodes without involving the inferior tracheobronchial,
superior tracheobronchial, or paratracheal nodal chain. Routine cervical
mediastinoscopy does not sample the anterior mediastinal node group.
Parasternal anterior mediastinotomy was performed in 28 patients with left
upper lobe carcinoma and normal findings from cervical mediastinoscopy.
Despite the normal findings at cervical mediastinoscopy, 10 of the 28
patients were deemed to have inoperable disease because of spread of the
neoplasm to the anterior nodal group or because of direct neoplastic
involvement of the aorta or main pulmonary artery. All patients in whom
results of anterior mediastinotomy were normal had resectable lesions at
thoracotomy. Fourteen of the 16 patients who came to thoracotomy had normal
hilar nodes. Parasternal anterior mediastinotomy, introduced by
Chamberlain, should be performed in addition to standard cervical
mediastinoscopy if the nodal drainage of left upper lobe neoplasms is to be
more completely evaluated. Combining these two procedures samples all major
drainage pathways except the posterior mediastinal nodal chain.
