Objectives: We evaluated the diagnostic power of different used evaluation criteria in ultrasound 2B, Doppler and elastography.
Method: Retrospective data analyses of all cases with breast lumps, that were evaluated and also operated during the study follow-up period. Study period: January 2011–April 2013 (Table 1).
Ductal breast ultrasound, Doppler and real-time elastography was performed with a HITACHI EUB 7500 HV machine, with 6–13 MHz variable frequency linear probe, with water bag, Hitachi Medical System, Tokyo, Japan. Ueno score and also strain ratio were measured for all described lesions. ACR4 lesions were referred to the surgeon. Some ACR3 lesions were also referred to the surgical cure. Extemporaneous and postsurgical histopathological exam was performed in all cases. Some ACR3 lesions were also referred to the surgeons because of cosmetic, pre-pregnancy, need of hormonal contraception use reasons.
Results: Study group was comprised only by the operated cases. We calculated the diagnostic power of different parameters in identifyiung cases with breast cancer.
| Parameter | Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) |
| Lump size >2.5 mm | 20.83 | 89.21 | 57.69 | 61.58 |
| Perpendicular dominant axis | 52.77 | 89.21 | 77.55 | 72.8 |
| Iregular margins | 48.61 | 89.21 | 76.08 | 71.09 |
| Inhomogenous content | 15.27 | 85.29 | 58.78 | 89.86 |
| Spiculated shape | 25.49 | 75.0 | 62.25 | 77.15 |
| Increased vascularity | 54.16 | 75.49 | 60.93 | 70.0 |
| Three out of five criteria | 63.81 | 63.75 | 68.64 | 58.62 |
| Four out of five criteria | 65.71 | 68.28 | 65.40 | 58.62 |
| Five out of six criteria | 68.42 | 50.74 | 61.17 | 58.62 |
| UENO SCORE >3 | 90.41 | 81.91 | 79.51 | 91.66 |
| FLR ratio >4.99 | 94.4 | 94.11 | 92.0 | 96.0 |
Conclusion: There is a net diagnostic value difference in favor of real-time elastography, in identifying breast cancer cases.
