Summary
Evaluating 200 thyroid nodules, this study found an 18% malignancy rate. Clinical signs and thyroid scans were unreliable; fine needle aspiration showed low diagnostic accuracy, suggesting cervicotomy for suspicious nodules.
Area of Science:
- Endocrinology
- Oncology
- Surgical Pathology
Background:
- Thyroid nodules are common, with varying malignancy risks.
- Accurate diagnosis and management of thyroid nodules remain challenging.
- Distinguishing benign from malignant nodules impacts treatment decisions.
Purpose of the Study:
- To evaluate diagnostic methods for thyroid nodules.
- To determine the malignancy rate in a clinical setting.
- To assess the efficacy and limitations of various diagnostic and surgical approaches.
Main Methods:
- Analysis of 200 thyroid nodule cases from Laennec Hospital.
- Comparison of clinical examination, isotope scans, fine needle aspiration, and ultrasound.
- Review of pre- and post-operative histology and long-term follow-up data.
Main Results:
- Malignancy rate was 18% among the analyzed thyroid nodules.
- Clinical examination showed suspicious signs in most malignant cases.
- Thyroid isotope scans (82% cold) and fine needle aspiration had limited diagnostic value.
- Ultrasound was only reassuring for small, thin-walled cysts, a rare finding.
Conclusions:
- Current diagnostic methods for thyroid nodules have significant limitations.
- Early surgical intervention with histological examination is recommended for suspicious nodules.
- Cervicotomy with frozen section analysis and lobo-isthmectomy offer a viable management strategy with minimal complications.
