| dc.description.abstract | A 2.1-fold increase in the rate of thyroid carcinoma is observed in Sri Lanka during the
past decade. Despite high incidence of thyroid tumors (7% of the population), malignancy
rate was 5%. Effective methods of preoperative diagnosis are crucial for effective patient
management. A descriptive cross-sectional study was conducted to evaluate the diagnostic
utility of Ultrasound Scan (USS) in the preoperative diagnosis of thyroid tumors. The
study enrolled 108 patients with radiologically suspected malignant nodules. USS findings
were reported according to the Thyroid Imaging Reporting and Data System (TIRADS),
and the results were compared with the final histological diagnosis. Among the 108
participants, the majority were females (78%), and their ages ranged from 15 to 75 years,
with a mean age of 47.5. Histology results were available for only 35 individuals, with
77.14% (27 cases) confirmed as malignant. In the 27 histologically confirmed malignant
cases, there were fourteen (n=14) reported as 4c, three (n=3) as five. TIRADS system shows
a moderate, positive and insignificant correlation (p>0.05) when compared with histology
results. Based on the findings, TIRADS system proved to have a 50% specificity and thus
additional investigations are required for further preoperative diagnosis. | |
