[About changes in the structure of surgically treated goiter]

Area of Science:

• Endocrinology
• Surgical Oncology
• Pathology

Background:

• Goiter and thyroid carcinoma represent significant endocrine and oncological challenges.
• Surgical intervention remains a primary treatment modality for various thyroid conditions.
• Longitudinal studies are crucial for understanding epidemiological shifts in thyroid diseases.

Purpose of the Study:

• To compare the incidence of different goiter types and thyroid carcinomas over two distinct surgical periods (1974-1985 and 1986-1996).
• To identify statistically significant trends in operated Basedow goiter and thyroid cancer rates.
• To analyze changes in the frequency of differentiated and anaplastic thyroid carcinoma subtypes.

Main Methods:

• Retrospective analysis of surgically treated goiter and thyroid carcinoma cases from 1974 to 1996.
• Comparison of disease incidence between two defined time intervals: 1974-1985 and 1986-1996.
• Statistical evaluation to determine the significance of observed changes in disease types and subtypes.

Main Results:

• A statistically significant decrease in the incidence of operated Basedow goiter was observed.
• A significant increase in the overall incidence of thyroid cancer was identified.
• The frequency of differentiated and anaplastic thyroid carcinoma subtypes showed changes between the two study periods.

Conclusions:

• The epidemiological landscape of surgically treated thyroid conditions has shifted, with declining rates of Basedow goiter and rising thyroid cancer incidence.
• These findings highlight the need for ongoing surveillance and potential adjustments in clinical management strategies for thyroid disorders.
• Further research into the etiological factors driving these observed trends in thyroid carcinoma is warranted.
