[Catamnestic evaluation of the results of surgical and combined treatment of pituitary tumors].

The work deals with the study of the results of surgical and combined treatment of 455 patients with adenoma of the hypophysis who were operated on between 1971 and 1977. the catamnestic follow-up periods ranged from 2 to 7 years and more. Microsurgical techniques were used in operations on 146 patients, 309 patients underwent operation by the traditional method. Among 455 patients, 190 were treated by surgery alone, whereas 265 patients received combined treatment (surgical intervention and radiotherapy, mostly in the postoperative period). Study of the results of catamnestic investigation showed that with the use of microsurgical techniques the intervention was more radical and tumors with pronounced extrasellar growth could be removed. The current diagnostic and surgical means as well as combined therapy (surgery combined with radiotherapy) do not solve the problem of the prevention of recurrent tumors of the hypophysis. Recurrences were observed in 22.1% of cases after surgical intervention and in 11.1-15.18% of cases after combined treatment. Combined therapy produces poorer results from the standpoint of correction of the visual and hormonal disorders. The existence, of a considerable number of recurrences makes necessary exact identification of the histobiological and hormonal nature of the whole group of adenomas because the classification accepted today does not meet the essence of the clinical problems encountered in the treatment of these tumors. An exact classification of adenomas of the hypophysis according to their spread is necessary.
