[Diagnosis and treatment of mediastinal tumors]

The analysis of treatment of 103 patients with sizable mediastinal formations is adduced. In 50 patients the disease was revealed during prophylactic photoroentgenography. In 44 (42.7%) patients malignant tumor was revealed, in 37 (84.1%) of them the diagnosis was confirmed according to morphological investigation data before beginning of the treatment, in 7--while the operation performance. Of 32 patients with malignant tumor operated on in 25 preoperative irradiation therapy was conducted, in 19 the tumor was excised entirely and in 4--partially, in 9 it was not possible to excise it at all. In 13 patients postoperative complications occurred and 2 (2.3%) died. The authors propose to confirm the mediastinal formation diagnosis by preoperative morphological investigation data. In absence of possibility of morphological diagnosis conduction it is necessary to perform operative intervention. In the case of malignant solid tumor present preoperative irradiation therapy in the middle fractioning regimen is expedient.
