Purpose: Breast mass - the most common occurences in the breast must be managed by a method that provides both the best medical and cosmetic results.
Methods: Two hundred seventy-eight patients evaluated and managed for breast mass at our center between January 1998 and December 1999 were analysed. In this study, we compare the results of the triple test score (TTS; sum of physical
examination, mammography, and fine needle aspiration cytology) with those from each separate diagnostic test according to a standard formula incorporating sensitivity, specificity, positive predictive value, and negative predictive value. The TTS
was
modified to substitute sonography for mammography-TTSs. The TTS was also compared to the TTS-2 that double weighted the results of fine needle aspiration (FNA), but was otherwise the same as the TTS.
Results: The sensitivity and specificity of breast sonography were 90% and 84% whereas those of mammography were 84% and 73%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of the TTSm
(triple
test score-mammography) were 99%, 97%, 99% and 97% respectively. The scores of the TTSm-2 were 99%, 100%, 100% and 97%. And those of the TTSs were 100%, 100%, 100% and 100%.
Conclusion: The TTS was more accurate than each of the elements separately in evaluating breast masses. The TTSs was also more effective than the TTSm. The TTS-2 was more useful than the TTS, being less likely to miss malignancy due to the
high
accuracy of FNA.
