Abstract
Thirty eight patients with mediastinal tumor were reviewed, including 17 neurogenic tumors, 7 bronchogenic tumors, 5 teratomas, 4 thymic tumors and 2 lipomas. Thirty seven cases were surgically treated. Twenty nine cases of them had benign tumors and their operative results were excellent. Seven out of nine malignant tumors were neuroblastomas (1 stage III and 6 stage IV). Five of 7 patients are still alive without tumor more than two years since operation, but 2 elder patients of stage IV have died. Complete removal of mediastinal neuroblastomas (stage III,IV) were successfully carried out in all cases. High rate of complete removal of primary tumor may contribute to their favorable prognosis.
