[Validity of diagnostic studies in thyroid pathology. Retrospective study]

Area of Science:

• Endocrinology
• Diagnostic Imaging
• Surgical Pathology

Background:

• Increasing number of diagnostic tests for thyroid diseases.
• Need to evaluate the validity of various diagnostic methods.

Purpose of the Study:

• To retrospectively evaluate the diagnostic utility of multiple tests for thyroid lesions.
• To assess the role of these tests in treatment planning.

Main Methods:

• Retrospective analysis of 2500 patients (1500 operated).
• Evaluation of scintiscanning, oncotropic indicators, echography, needle biopsy, thyrolymphography, and thyroid hormones.

Main Results:

• Scintiscanning and needle biopsy are primary for lesion nature determination.
• Echography provides supplementary, non-essential information.
• Oncotropic indicators and thyrolymphography lack diagnostic value.
• Thyroid hormone levels are crucial for managing hot lesions, suspected thyroiditis, and hypothyroidism.

Conclusions:

• Diagnostic examinations for thyroid lesions should be used more selectively.
• Scintiscanning and needle biopsy are key diagnostic tools.
• Thyroid hormone testing is indicated in specific clinical scenarios.
