Abstract

Amaç: Meme kanserinin shear-wave elastografi (SWE) bulgularını değerlendirerek, diğer görüntüleme teknikleri ile farklılıklarını karşılaştırmayı ve moleküler alt tipler arasındaki ilişkiyi belirlemeyi amaçladık.
Yöntem: Meme kitlesi nedeniyle biyopsi yapılan ve malign tanı alan hastaların radyolojik bulguları ve histopatoloji sonuçları retrospektif olarak değerlendirildi. SWE bulguları, ultrasonografi (US), mamografi ve manyetik rezonans görüntüleme (MRG) bulguları değerlendirildi. US-SWE rehberliğinde yapılan tru-cut biyopsinin histopatoloji sonuçları incelendi. SWE ve diğer radyolojik tekniklerin bulguları istatistiksel olarak karşılaştırıldı ve moleküler alt tipler ile ilişkisi değerlendirildi.
Bulgular: 51 hastanın median yaş değeri 58’ di. SWE'de ortalama tümör boyutu 20 mm ve tümör elastisite değeri 105 kPa idi. B modu US-SWE ile ölçülen tümör boyutu farklılıkları ile tümör elastisite değeri arasında istatistiksel olarak anlamlı korelasyon bulundu. SWE bulguları ile moleküler alt tipler arasında anlamlı ilişki saptanmadı. SWE, lezyon boyutu açısından mamografi ve MRG ile anlamlı derecede yüksek pozitif korelasyona, US ile çok yüksek pozitif korelasyona ve ER pozitifliği ile zayıf negatif korelasyona sahipti.
Sonuç: Konvansiyonel radyolojik görüntüleme tekniklerine ek olarak, SWE' nin kullanımı meme kanserinin değerlendirilmesinde yararlı bilgiler sağlamaktadır.

Relationship of Shear-wave Elastography Findings with Breast Cancer Molecular Subtypes and Comparison with Other Radiological Imaging Techniques

Abstract

Purpose: We aimed to evaluate the shear-wave elastography (SWE) findings of breast cancer and to compare their differences with other imaging techniques and to determine the rela-tionship between molecular subtypes.
Methods: Radiological findings and histopathology results of patients who underwent biopsy due to breast mass and diagnosed as malignant were evaluated retrospectively. SWE findings, ultrasonography (US), mammography and magnetic resonance imaging (MRI) findings were evaluated. The histo-pathology results of the tru-cut biopsy performed under the guidance of US-SWE were analyzed. The findings of SWE and other radiological techniques were compared statistically and relationship with molecular subtypes was evaluated.
Results: We had 51 patients with a median age of 58 years. In SWE, the mean tumor size was 20 mm, and the tumor elasticity was 105 kPa. Statistically signi-ficant correlation was found between the tumor size differences measured by B mode US-SWE and the tumor elasticity value. No correlation was found between SWE findings and molecular subtypes. SWE had significantly high positive correlation with mamography and MRI in terms of lesion size, with US very high positive correlation and with ER positivity weak negative correlation.
Conclusion: In addition to conventional radiological imaging techniques the use of SWE provides useful insight to evaluation of breast cancer.
