Abstract:
OBJECTIVE
To determine the predictive values of the TIRADS and Bethesda Scoring Systems in diagnosing thyroid malignancy at the Quezon City General Hospital.
METHODSDesign: 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
RESULTSA 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.
CONCLUSIONOur study showed that the Bethesda classification had good specificity, positive predictive value, accuracy and fair sensitivity while the TIRADS system had poor predictive value
