OBJECTIVE

To determine the predictive values of the TIRADS and Bethesda Scoring Systems in diagnosing thyroid malignancy at the Quezon City General Hospital.

METHODS

Design: Retrospective Review of Records

Setting: Tertiary Government Training Hospital

Participants: Records of patients aged 18 years old and above who were admitted and underwent thyroidectomy under the Department of Otorhinolaryngology-Head and Neck Surgery from 2018 to 2023

RESULTS

A total of 47 patient records were included, 16 had thyroid malignancy while 31 had benign histopathology results. The Bethesda system showed 60% sensitivity, 94% specificity, 82% positive predictive value and 83% accuracy while the TIRADS system showed 53% sensitivity, 50% specificity, 33% positive predictive value,and 51% accuracy. Using Chi-Square tests, the Bethesda system had a strong association (p value < .0001), while the TIRADS system had no significant association (p value 1.000) with thyroid malignancy [odds ratios 24.2 and 1.00] respectively.

CONCLUSION

Our study showed that the Bethesda classification had good specificity, positive predictive value, accuracy and fair sensitivity while the TIRADS system had poor predictive value
