Significance of metastatic disease in subaortic lymph nodes.

Thirty-five patients underwent resection of primary bronchogenic carcinoma of the left upper lobe or left main bronchus in the presence of metastatic disease in subaortic lymph nodes. No patient had metastatic disease in other mediastinal node stations. There was 1 postoperative death. Complete follow-up is available on 34 patients. Three-year and five-year actuarial survival for the entire group is 44% and 28%, respectively. For 23 patients undergoing complete resection, five-year actuarial survival is 42%. Resection of primary bronchogenic carcinoma in the presence of subaortic nodal metastases is associated with improved survival relative to reports of survival following resection of metastatic disease in other mediastinal node stations. Resection should be undertaken in these patients especially when it is judged that the resection is likely to be complete.
