The solitary thyroid nodule revisited

Area of Science:

• Endocrinology
• Surgical Oncology
• Diagnostic Pathology

Background:

• Solitary thyroid nodules are common clinical findings.
• Management strategies evolve over time.
• Comparative studies are essential for tracking trends in diagnosis and treatment.

Purpose of the Study:

• To compare the presentation, diagnosis, and surgical management of solitary thyroid nodules over a ten-year period.
• To evaluate changes in diagnostic accuracy and surgical approaches.
• To assess the incidence of malignancy in solitary thyroid nodules.

Main Methods:

• Retrospective analysis of 195 clinically solitary thyroid nodules.
• Comparison with a matched series from a decade prior.
• Review of diagnostic methods, focusing on fine needle aspiration (FNA).
• Analysis of surgical interventions, including nodulectomies and more extensive resections.

Main Results:

• No significant change in the pattern of presentation for solitary thyroid nodules.
• Increased reliance on fine needle aspiration for preoperative diagnosis.
• Low false negative rate (2%) and no false positive rate for FNA.
• Shift towards more conservative surgical management, such as nodulectomies.
• Incidence of malignancy in solitary thyroid nodules was 10.2%.

Conclusions:

• Fine needle aspiration has become the preferred diagnostic tool for solitary thyroid nodules.
• Surgical management trends towards conservatism.
• The incidence of malignancy in solitary thyroid nodules remains consistent.
