Fifteen lung cancer (LC) and 11 malignant mediastinal tumor (MMT) patients who received surgical treatment in association with a reconstruction of great vessel from 1981 to 1997 were retrospectively reviewed. The aorta was resected in 7 (AO group) of 15 LC patients and the superior vena cava in the remaining 8 patients (SVC group). Pathological examination revealed actual tumor invasion in one (14%) of AO group and 6 (75%) of SVC group. In 7 p-T4 patients, 6 (85.7%) were p-N2 or N3 diseases. Five of the 6 patients belonged to SVC group and one to AO group. Five-year survival rate was 10% in all LC patients, 20% in p-T3 patients, 0% in p-T4 cancers, 50% in p-N0 patients and 0% in p-N2 or N3 patients. Eleven MMT patients included 5 thymomas, 2 thymic cancers and 4 germ cell tumors. SVC was resected and replaced with ringed PTFE graft in all patients. Invasion of vessel wall was diagnosed pathologically in 10 of 11 patients. Fifteen-year survival rate was 60% in 5 thymoma patients but 4 of whom had distant metastasis. Five-year survival rate was 50% in thymic cancers and 0% in germ cell tumors. Since the prognosis of LC and MMT patients who have tumor invasion of the great vessel is very poor, induction therapy based on preoperatively pathological diagnosis is recommended.
