Abstract:
Objective:To study the characteristics of tumor microvascular perfusion by contrast-enhanced ultrasound (CEUS) in patients with breast cancer, and to analyze its relationship with pathology.Methods:The clinical data of 180 breast cancer patients admitted to Tangshan People′s Hospital from February 2019 to March 2021 were retrospectively analyzed. They were examined by contrast-enhanced ultrasound before surgery, and the specimens were sent for pathological biopsy after surgery. The characteristics of tumor microvascular perfusion under CEUS were observed, and the correlation between the characteristics and pathological classification and grade were analyzed.Results:The results of the CEUS showed that the contrast agentrapid infusion was 47.78%(86/180), slowly filled was 60.00%(108/180), the mass showed hyperenhancement when the contrast agent reached its peak was 42.78%(77/180), the contrast agent slowly withdrew was 42.78% (77/180), and the contrast agent retention in clearance was 65.56% (118/180). Pathological biopsy revealed that among 180 patients, 16 patients (8.89%) were non-invasive carcinoma, 41 patients (22.78%) were invasive lobular carcinoma, 88 patients (48.89%) were invasive ductal carcinoma, 10 patients (5.56%) were mucinous adenocarcinoma, 11 patients (6.11%) were medullary carcinoma, 8 patients (4.44%) were squamous carcinoma, 6 patients (3.33%) were hard carcinoma (3.33%). There was no correlation between tumor microvascular perfusion characteristics and pathological classification under CEUS ( P>0.05). Pathological biopsy showed that 95 patients (52.78%) were grade Ⅰ, 49 patients (27.22%) were gradeⅡand 36 patients (20.00%) were grad Ⅲ. There was a certain correlation between tumor microvascular perfusion characteristics and pathological grade under CEUS ( P<0.05). Conclusions:There is a certain relationship between tumor microvascular perfusion characteristics detected by CEUS and pathological grading in patients with breast cancer. Analysis of the microvascular perfusion characteristics can provide an important basis for pathological grading.
