ABSTRACT
Objective:
To investigate the comparative analysis of multimodal ultrasound features and clinicopathology of different molecular types of breast cancer, so as to improve the diagnostic accuracy of different types of breast cancer.Methods:
A retrospective analysis of 112 patients with invasive breast cancer in the Second Affiliated Hospital and Affiliated Cancer Hospital of Harbin Medical Univeristy from August 2017 to November 2018 was carried out. With reference to St.Gallen standard, breast masses were divided into four subtypes, including Luminal A (LA), Luminal B (LB), Her-2 overexpression (Her-2+ ) and triple negative (TN). Two-dimensional greyscale, color Doppler flow imaging, shear wave elastography and contrast-enhanced ultrasound images were performed before operation. Complete clinicopathological data were collected. The differences between different subtypes of breast cancer in terms of multimodal ultrasound and clinicopathological features were analyzed.Results:
①Luminal breast cancer showed posterior echo attenuation, low Alder grade, low Emax and Eratio value. LA was more likely to show a speculated or angular margin and concentric enhancement; LB was more frequently to show a indistinct margin, low enhancement and no perfusion defect (all P<0.05). ②Her-2+ cancers were characterized with a indistinct margin, enhanced posterior echo, a high Alder grade, Emax and Eratio value, and a high contrast enhancement and perfusion defect. The TTP value was lower than other subtypes (all P<0.05). ③TN cancers were associated with microlobulated margin, posterior echo enhancement, low Alder grade, high Emax and Eratio value and Ki67 expression, contrast concentric enhancement have and perfusion defect (all P<0.05).Conclusions:
Different molecular subtypes of breast cancer have different multimodal ultrasound features and clinicopathological appearances, which can provide more imaging information for clinical diagnosis, treatment, and prognosis.
