RATIONALE FOR THE APPLICATION OF CALCITONIN LEVEL IN THE EARLY POSTOPERATIVE PERIOD TO EVALUATE THE EFFECTIVENESS OF SURGICAL TREATMENT OF MEDULLARY THYROID CANCER.

Purpose: To determine the effectiveness of the basal calcitonin (CTb) determination in the early postoperative period to predict the possible recurrence (persistence) of medullary thyroid cancer (MTC).

Material And Methods: A retrospective study of the treatment results in 194 patients with MTC (148 (76.3%) primary - group 1 and 46 (23.

Outcomes of laser-induced thermotherapy for thyroid nodules at the West Vascular Center, Ukraine.

Thyroid nodules are common, occurring in 50-60% of healthy patients. Currently, there are no effective conservative treatment options for nodular goiter, and surgery can have limitations and potential complications. The purpose of this study was to evaluate the efficacy, tolerability, and long-term results of using sclerotherapy and laser-induced interstitial thermotherapy (LITT) to treat benign thyroid nodules.

Breast cancer relapses considering molecular biological characteristics.

We aimed to analyze the frequency of breast cancer relapses and their relationship with molecular and biological tumor characteristics. We studied 6,136 breast cancer patients, including 146 with relapses (Group 1) and 455 without relapses (Group 2). We divided the patients based on age, menstrual function, disease stage, histology form and grade, and molecular-biological subtype.

Topical Diagnosis and Determination of the Primary Hyperaldosteronism Variant.

Laboratory diagnosis of primary hyperaldosteronism is based on determining blood levels of aldosterone, renin on request, potassium, and sodium. The results of these studies are significantly influenced by drugs, preparation for the study and blood collection methods, age, gender, and concomitant diseases. The work analyzes the factors influencing the results of the study of aldosterone and identifies the main ways of their exclusion at each stage of the diagnosis.

Laboratory Diagnostics of Primary Hyperaldosteronism and its Peculiarities (Literature Review).

The final stage of the diagnostic of primary hyperaldosteronism is to identify the causes of excessive secretion of aldosterone and determination of its variants. Based on the analysis of literature data, the diagnostic value, sensitivity and specificity of the methods of radiation diagnostics for primary hyperaldosteronism were assessed: ultrasound, computed tomography, magnetic resonance imaging, photon emission tomography, magnetic resonance spectroscopy, scintigraphy with iodine radiopharmaceuticals. The causes of false-positive and false-negative evaluations of changes in adrenal glands in the application of these diagnostics have been analyzed.
