Abstract:
Objectives:
To determine if ultrasound can increase the accuracy of fine needle aspiration biopsy in confirming malignancy in clinically malignant breast masses.
Methods:
Clinically malignant breast masses underwent ultrasound, fine needle aspiration biopsy/cytology, and tissue biopsy. Accuracy of each test and in combination were calculated using histopathology as gold standard.
Results:
The accuracy of ultrasound alone was only 67.5% sensitivity of 90.0%, specificity of 33.3%, positive predictive value of 67.2% and negative predictive value of 68.8%, while FNAB alone has an accuracy of 89.2%, sensitivity of 90.0%, specificity of 87.9%, postive predictive value of 91.8%, and negative predictive value of 85.3%. With concordant findings in ultrasound and FNAB, accuracy, sensitivity, specificity, positive predictive value, and negative predictive value are 94.3%, 97.6%, 81.8%, 95.3%, and 90%, respectively.
Conclusion:
With concordant findings in ultrasound and FNAB, accuracy in confirming malignancy is 94.3%.
Key words: breast cancer, breast ultrasonography, fine needle aspiration biopsy/cytology
