ABSTRACT
As a disease with high morbidity and mortality, cardiovascular disease always threatens human health at all times. Exploring the risk factors has always been the research direction of physicians. In recent years, it has been found that breast artery calcification is closely related to the occurrence and development of cardiovascular disease, which is one of the potential risk factors. The present paper reviews the overview, grading methods, incidence and related studies of breast artery calcification and cardiovascular disease, and explores in-depth the correlation between breast artery calcification and cardiovascular disease in order to provide a basis for improving the assessment of cardiovascular disease risk.
ABSTRACT
Objective The objective of this study was to investigate the relationship between the molybdenum target imaging features and clinical signs of mammography,and the expression of HER-2 receptor in breast cancer patients with positive receptors of estrogen and progesterone. Methods One hundred and eleven patients with estrogen and progesterone receptor-positive breast canc-er who were admitted to our hospital from July to September 2017 were examined with mammography before operation. Immunohisto-chemical analysis was performed on breast cancer tissues. Pathological features and features related to mammography were analyzed af-ter operation. The relationship between clinicopathological features and mammography-related signs,and HER-2 expression was al-so analyzed statistically. Results Of the 111 patients,34 were HER-2 positive patients. There were significant difference between the observed indicators and the over-expression of HER-2(P<0. 05). These indicators included lymph node metastasis,calcifica-tion of the mass,margin of the mass,the shape of calcification,and the blood status of vessels. The mammography of patients with tri-ple positive breast cancer is more likely to manifest as lymph node enlargement,mass with calcification or simple calcification,margin-al burrs,granular calcification,and vascular thickening. Conclusion The expression of HER-2 in breast cancer patients with posi-tive estrogen and progesterone receptors can be reflected to some extent by lymph node metastasis,tumor with calcification,tumor mar-gin,calcification,calcification morphology and peripheral blood vessel thickening. In terms of clinical conditions,The biological behav-ior and characteristics of tumor can be inferred based on the clinicopathological features of the patient and the imaging findings of the mammography,providing a direction for the treatment and evaluation of prognosis in breast cancer patients.
ABSTRACT
Objective • To investigate the relationship between the mammographic signs and the pathological features in breast cancer. Methods • From August 2015 to August 2018, 300 patients with primary breast cancer confirmed by operation and pathology in Shanghai First Maternity and Infant Hospital, Tongji University were selected. All patients had mammography before operation. The relation between characteristics of molybdenum target imaging and pathological types were retrospectively analyzed. The correlation between specific imaging signs such as lump, calcification, spiculation sign and important pathological features were further analyzed. Results • Among 300 cases of breast cancer, 251 cases (83.7%) had lumps, of which 183 cases had spiculation sign, and 190 cases had calcification. Besides, 235 cases (78.3%) had calcification; 77 cases (25.7%) had structural disorder with diffuse density; 98 cases (32.7%) had positive signs of vascular symptoms. Lump (95.1%), spiculation sign (82.3%) and calcification (83.7%) were mostly observed in invasive ductal carcinoma. Structural disorder (88.2%) was mostly observed in invasive lobular carcinoma. Calcification (96.1%) and lump (60.8%) were mostly observed in intraductal carcinoma. Calcification (100.0%) was mostly observed in lobular carcinoma in situ. Lump was mostly observed in simple carcinoma, medullary carcinoma and mucinous adenocarcinoma. The positive expression rates of estrogen receptor (ER) and progesterone receptor (PR) were higher in patients with tumor lump >5 cm than those with tumor lump ≤ 5 cm, but there were no significant differences (P=0.165, P=0.317). The positive rate of ER was 54.5% and the positive rate of PR was 60.8% in patients with calcification, which were lower than those without calcification (P=0.027, P=0.006). The positive rate of PR in patients with spiculation sign was 71.6%, which was higher than those without spiculation sign (P=0.018). But there was no significant difference in the expression of ER in patients with or without spiculation sign (P=0.321). Patients with lumps alone had a lower incidence of lymph node metastasis (29.5% vs 37.9%, P=0.009), and lower histological grade (P=0.043), in comparison with patients with lumps and calcification. But they had higher ER positive rate (70.5% vs 57.9%, P=0.033) and PR positive rate (73.8% vs 65.3%, P=0.014). Conclusion • Breast cancer patients with different pathological types show different signs of mammography which may have certain associations with the expression of immunohistochemical indicators such as ER and PR. Simple lump shadows in mammography may be a predictor in the good prognosis of breast cancer.

ABSTRACT
Objective To investigate the diagnosis and treatment of mammographic calcifications found by mammary molybdenum target inspection.Methods 150 women who were found out with breast calcifications by mammary molybdenum target inspection and had been treated with surgical excision biopsy were selected.Their clinical data were retrospectively analyzed.Results In 150 cases of mammographic calcifications,102 cases were benign lesions by pathologic diagnosis,and 48 cases were malignant.Compared the morphological characteristics of the benign and malignant breast calcifications,the nature of the lesion was associated with lesion size (x2 =5.55),the density of calcification (x2 =7.591) and the distribution of calcifications (x2 =11.859).Conclusion Mammographic calcifications found by mammary molybdenum target inspection has a certain clinical value for diagnosis and treatment of breast cancer,so such patients should be encouraged to do biopsy to diagnose or exclude breast cancer.
ABSTRACT
Objective To study the consistency between pathology and the single and combined diagnosis of negative breast cancer by ultrasonography and mammography.Methods 90 clinical case data of patients with palpable negative breast tumors and mammography revealed small calcifications were retrospective analyzed.All patients were received the high frequency ultrasound.The value of two methods and combined diagnosis in the diagnosis of breast cancer with palpation negative were compared,which the pathological biopsy was the gold standard.Results The pathological showed that there were 58 cases of benign tumors,32 cases of malignant tumors,10 cases of stage 0,18 cases of stage Ⅰ,4 cases of stage Ⅱ.The high frequency ultrasonography was consistent with pathological(Kappa =0.641).The AUC of diagnosiing the breast cancer was 0.775.The molybdenum target radiography was consistent with pathological (Kappa =0.725),and the AUC was 0.830.The high frequency ultrasonography combined with molybdenum target radiography was highly consistent with pathological(Kappa =0.879),and the AUC was 0.934.The accuracy of combined diagnosis was higher than that of high frequency ultrasound (P ＜ 0.05) and molybdenum target radiography(P ＞ 0.05).Conclusion The high frequency ultrasonography and molybdenum target radiography have advantages in the diagnosis of palpable negative breast cancer.The joint diagnosis helps to achieve complementary strengths,has high consistency with pathology,and help to improve the diagnostic accuracy.
ABSTRACT
Objective To analyze and compare the independent and combined diagnostic values of high frequency ultrasonography (HFU) and molybdenum target imaging (MTI) for early breast tumor in a prospective study.Methods 258 patients with breast mass which were suspected as breast tumors by physical examination received HFU,MTI,their combined applications and operative treatments.Comparative studies were made between the surgical pathology and imaging evaluations.Results Totally 258 cases were enrolled in this study.Surgical pathology confirmed 135 cases of early breast cancer and 123 cases of benign breast tumor.For the diagnosis of early breast cancer,combined application was more effective than HFU or MTI alone in sensitivity (P0.05).In the patients of early breast cancer, compared with HFU,MTI found less nodules of calcification(18.3% vs 36.5%,P<0.01),but revealed more axillary lymph metastasis (69.0% vs 33.3%,P<0.01).Conclusion HFU and MTI alone or their combined application are reliable imaging methods for the diagnosis of early breast cancer.For the sensitivity and accuracy of diagnosis, combined applications has more superior advantages.

ABSTRACT
Objective:To evaluate the diagnosis significance of breast mammography assisted by hook-wire localization biopsy for BI-RADSⅣand above negative or non-palpable breast lesions. Methods:A total of 48 cases of mammary molybdenum target with BI-RADSⅣlevel and above but with clinical-touched negative or non-palpable breast lesions (including 4 bilateral lesions and 44 uni-lateral lesions;total of 52 lesions) were used in the mammography aided by hook-wire localization biopsy. Results:Among the 52 le-sions, 13 cases were malignant lesions (single), 6 cases were at Stage 0 (accounted for 46.15%), 5 cases were in Stage I (38.46%), and 2 cases were in StageⅡ(15.39%). The remaining 39 cases were benign lesions. Results showed that the detection rate for breast cancer was 25.0%. A total of 39 cases of benign lesions and 10 cases of malignant lesions were found among mammography BI-RADSⅣpa-tients. Zero cases of benign lesions and 3 cases of malignant change were found among BI-RADS Ⅴ patients. The positive rates of breast cancer among BI-RADSⅣandⅤpatients were 25.64%and 100%, respectively. Conclusion:Breast mammography assisted by hook-wire localization biopsy could precisely excise both BI-RADSⅣandⅤnegative/non-palpable breast lesions. This technique can also improve the quality of life and prognosis of patients. It is a safe, accurate, and low-cost diagnostic method. Thus, breast mammogra-phy assisted by hook-wire localization biopsy must be widely used in clinical applications in China.
