OBJECTIVE: To determine the predictors of the aggressive course of adrenocortical cancer (ACC). ACC is a rare malignant neoplasm of the adrenal cortex with a variable prognosis. At present, predicting the course of the disease and clinical outcome in patients presents significant difficulties, since many aspects of the treatment of ACC have not been studied or require clarification. In particular, the prognostic value of markers that are used in clinical practice has not been fully determined.
MATERIAL AND METHODS: Histological and immunohistochemical studies of the surgical material of adrenal neoplasms were performed. The study included 73 patients with a histologically confirmed diagnosis of ACC: 51 (69.9%) women and 22 (30.1%) men aged 17 to 82 years. Cox regression model was used for survival analysis. Statistically significant factors (p<0.05) according to the results of independent regression analysis were included in the Kaplan-Meier analysis followed by pairwise comparison using the log-rank test.
RESULTS: An increased risk of recurrence is associated with the presence of pathological mitoses and excessive secretion of aldosterone, death - with stage IV according to the classification of the European Network for the Study of Adrenal Tumors (ENSAT), relapse and death - the value of mitotic activity more than 20, the Ki-67 index more than 12, the classic variant. Mitotic activity and hormonal activity were independent predictors of recurrence-free survival, mitotic activity and ENSAT stage were independent predictors of overall survival.
CONCLUSIONS: In the present work, potential predictors of the course of ACC are identified, which are available for use in routine practice. Based on the totality of clinical, morphological, immunohistochemical data used in the diagnosis of ACC, a conception of the patient's survival can be obtained.
