title: [The clinical characteristics and surgical treatment of giant mediastinal tumors: an analysis of 140 cases].
abstract: The experience on the diagnosis and treatment of 140 cases of giant mediastinal tumors from Jan. 1978 to Dec. 1994 was summarized in this paper. The mean size of the tumors was 14.6 cm x 11.2 cm x 8.9 cm. Among the 140 cases, teratoma was seen in 58 cases (41.4%), thymoma in 32 cases (22.9%) and neurogenic tumors in 16 cases (11.4%). Correct preoperative diagnosis was made in 96.4% for ultrasongraphy (UG), 89.5% for CT and only 19.5% for thin needle biopsy (TNB). The resection rate was 82.9% (116/140) and the operative mortality was 2.14% (3/140). The authors suggest that for the giant mediastinal tumoor, besides chest X-ray, UG and chest CT should be the main preoperative diagnostic nethods, TNB and fibro-optic bronchoscopy are also helpful to define the border and the invasiveness of the tumor. The choice of incisions and attentions during the operation are discussed.
