Malignancy in Solitary Thyroid Nodule

Area of Science:

• Endocrinology
• Surgical Oncology
• Nuclear Medicine

Background:

• Solitary thyroid nodules are common, requiring accurate diagnosis to differentiate benign from malignant conditions.
• Radioiodine uptake patterns (cold, warm, hot) are crucial in evaluating thyroid nodules.
• Distinguishing malignancy risk in different nodule types is essential for patient management.

Purpose of the Study:

• To determine the relative frequency of malignancy in cold solitary thyroid nodules compared to hot and warm nodules.
• To analyze the clinical, ultrasonographic, and histopathological characteristics of solitary thyroid nodules.
• To assess surgical outcomes and complications associated with solitary thyroid nodule treatment.

Main Methods:

• Prospective study including 100 patients with clinically and ultrasonographically diagnosed solitary thyroid nodules.
• Radioiodine uptake scans (thyroid scans) classified nodules as cold, warm, or hot.
• All patients underwent surgical treatment (lobectomy or total thyroidectomy) followed by histopathological examination.

Main Results:

• The study found a higher malignancy rate (20.83%) in cold solitary thyroid nodules compared to other types.
• Histopathology revealed 16% of nodules were malignant (carcinoma), with papillary carcinoma being the most common type (50%).
• Common surgical complications included hoarseness of voice (5%), hematoma (4%), infection (2%), and hypoparathyroidism (3%).

Conclusions:

• Cold solitary thyroid nodules present a significantly higher risk of malignancy.
• Surgical intervention and histopathological analysis remain critical for diagnosing and managing solitary thyroid nodules.
• Understanding nodule characteristics aids in risk stratification and appropriate treatment planning for thyroid neoplasms.
