[Current status of surgery for mediastinal tumors].
Impact of surgery on the result of mediastinal tumors is variable: In benign tumors such as teratoma, congenital cyst, intrathoracic struma and neurogenic tumor, a complete resection causes a good result. Simultaneous thoracotomy and laminectomy should be performed in the Dumbbell type of neurogenic tumor. Since complete resection of the invasive thymoma promises a good prognosis, excision of all the tumor and invading tissues followed by radiation therapy is recommended in the treatment of thymoma. In pure seminoma resection and radiation therapy is the treatment of choice, while in non-seminomatous germ cell tumor, aggressive chemo- and radiation therapy should be performed, until tumor markers such as AFP and HCG become negative. The operation is to be followed afterwards. A mass screening test for neuroblastoma in infant facilitates an early detection of this disease and promises a good result by chemotherapy, radiation therapy, and surgery. There is still a possibility that the result of treatment of the malignant mediastinal tumors would be improved by exact diagnosis and intensive treatment.
