Abstract

BACKGROUND:

Nodular thyroid disease is a common endocrine problem. Most thyroid nodules are benign hyperplastic lesions, but 5-20% may be a true neoplasm. It is important to differentiate a benign from a malignant nodule early as the approach to treatment in the two is radically different. Early institution of medical management in a benign nodule may obviate the need for surgery.

PURPOSE OF THE STUDY:

The present work aims to study the efficacy of thyroxine suppression in the management of benign thyroid nodules.

MATERIALS AND METHODS:

A prospective study on patients presenting with thyroid nodule was undertaken. The diagnostic work-up included a clinical evaluation, thyroid function tests, thyroid scintigraphy and fine needle aspiration cytology. Based on the investigations, patients were segregated in Group A (toxic nodular goiter), Group B (benign euthyroid nodule) and Group C (malignant nodule). Group A patients were managed with antithyroid drugs and radioiodine and Group C patients were managed surgically. Group B patients were put on thyroxine suppression. Patients who failed to show reduction in size of the nodule at 18 months were treated surgically.

CONCLUSION:

The response rate of benign euthyroid nodule to thyroxine suppression was 76% in the present study.
