COMPARATIVE RESULTS OF THE USE OF MODERN EXAMINATION METHODS IN THE EARLY DIAGNOSIS OF KIDNEY CANCER, IN DETERMINING THE STAGE OF INVASION, AND IN CHOOSING STRATEGIES FOR ITS RADICAL TREATMENT.

This article deals with comparative results of the use of modern examination methods in the early diagnosis of kidney cancer, in determining the stage of invasion, and in choosing strategies for its radical treatment. The research work included 170 patients who were treated in department of urology of Azerbaijan Medical University with the diagnosis of kidney cancer from 2006-2016. The age range of patients was between 23-82 (average 61.7), 93(54.7%) were male and 77 (45.3%) were female. According to the application of radiation examinations, we have divided the patients into two groups who are under our observation. Only ultrasound examination was applied to the patients included in the first group for diagnostic purposes, while modern radiation examinations were applied comprehensively to the patients included in the second group. 63 of the patients included in the first group were satisfied with only the results of the ultrasound examination and the appropriate type of treatment was prescribed without additional examinations. In 107, examinations were applied in a complex manner (USM, CT, MRI). According to the results of our research, the response of USM to the stages of kidney cancer in determining the stage of process invasion is T1-97.9±1.2%, T2-94.2±2.3%, T3-92.2±2.5% %, T4-98.0±1.1%, and its sensitivity is 89.7±5.7% in T1 stage, 87.9±4.0% in T2 stage, 87.3±4.5% in T3 stage, It was 85.0±8.0.9% for T4 stage. In patients with kidney cancer, the diagnostic possibility of ultrasound examination and determination of the stage of invasion was 90.5% correct and 9.5% incorrect. 90.4% correct in the placement of the tumor, 9.6% incorrect, 86.9% correct in determining the size of the tumor tissue, 13.1% incorrect, 92.6% correct in 7.4% in determining the direction of development intrarenal wrong, extrarenal development is completely consistent. Specificity of computed tomography by stages in determining the degree of local spread of the process in patients with kidney cancer: T1-98.6±1.4%, T2-91.7±4.0%, T3-84.5±4.8%, T4-97.3±1.9% sensitivity and T1-90.9±8.7%, T2-80.6±6.6%, T3-80.8±7.7%, T4-72.7±13 it has been like this. Our retrospective review revealed that the screenings related to the stage of cancer development were satisfactory and there was no need for additional more complex and expensive screenings. In other patients (T3-T4), conducting preoperative thoracoabdominal CT and MRI examinations was considered important from the point of view of obtaining effective results in order to put an end to the controversial issues arising in the diagnosis and selection of radical treatment.
