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 evaluate the effect of breast blood oxygen functional imaging combined with mammography on breast cancer screening in women aged over 40 years.Methods A total of 10 076 cases of women in our hospital underwent breast blood oxygen functional imaging and mammography X -ray examination.The breast imaging report and data system (BI -RADS)III level of women performed on the biopsy pathology were used as the gold standard.The effect of different inspection methods were compared and analyzed.Results Among 10 076 cases,235 cases were diagnosed as BI -RADS,which was diagnosed by blood oxygen functional imaging system and a molybdenum target X -ray diagnosis of III.Thirteen cases with early breast cancer were diagnosed by needle biopsy.And 222 cases were diagnosed benign lesions.The sensitivity of the blood oxygen functional imaging system was 69.23% (9 /13)and 85.58% (190 /222), respectively.The sensitivity of molybdenum target X -ray was 76.92% (10 /13),and the specificity was 82.88% (184 /222).The sensitivity of combined detection was 100.0% (13 /13)and the specificity was 82.88% (184 /222).The accuracy index of combined molybdenum target X -ray (0.829)was significantly higher than that of single detection (0.548 and 0.598)(U =2.117,2.501,P <0.05).Conclusion Breast blood oxygen functional imaging instrument combined with molybdenum target examination could effectively improve the accuracy of diagnosis in breast cancer screening among women over 40 years.
