Differentiated approach to surgical treatment of adrenal glands tumors

Abstract

Objective – to improve the results of treatment of adrenal tumors by optimizing a differentiated approach based on the analysis of the results of various surgical invasions. The paper analyzed the results of treatment of 145 patients with various adrenal tumors, which were divided into 2 groups: І (n=71) - patients after adrenalectomies, II (n=74) – after adrenal resections. Organ-preserving invasions showed better results during the early and long-term postoperative period in patients with corticosteromas, pheochromocytomas and incidentalomas by reducing the severity of fluctuations in hemodynamic parameters and the frequency of adrenal insufficiency. Due to the introduction of the treatment algorithm, the number of adrenal resections increased by 26.6% in patients with neoplasms more than 4,0 cm in diameter (p=0.0001). The choice of surgical invasion should be individualized, taking into account the clinical features of the disease, hormone indicator parameters, the size of tumors, the comprehensiveness of the adrenal gland lesion and the ratio of the latter to nearby organs and structures. Adrenal insufficiency was detected 14.2% more often after adrenalectomies (р=0.044) compared to adrenal resections. Treatment according to the developed algorithm reduced the incidence of adrenal insufficiency by 5.8% (p=0.028). In the long-term postoperative period, contralateral gland tumors occurred with the same frequency (4.8%) among patients after adrenalectomies and resections. Relapse of the neoplasm after resections was detected in 3 (7.1%), as a result of which 2.4% underwent repeated operations with the final removal of the gland. An increase in the size of a single adrenal gland was more common by 21.4% after adrenalectomies.
