ABSTRACT
Objective: To investigate the correlation between the prognosis of breast cancer patients and mammographic calcification. Methods: A total of 1 035 breast cancer patients with complete clin ical information were in cluded in this study. According to mammographic calcification before operation, the patients were divided into calcification group and non-calcification group, and then the expressions of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER-2) were compared between two groups. The influence of calcification on the positive expression rates of ER, PR and HER-2 and the relationship between calcification and tumor size, axillary lymph node status, histological grade, molecular classification and prognosis were analyzed. Results: The rate of calcification in the patients with axillary node metastasis was significantly higher than that in the patients without lymphatic metastasis [53.6% (199/371) vs 47.1% (312/663)] (P 0.05). In survival analysis, there was no obvious difference between the calcification group and non-calcification group. Conclusion: The breast cancer with micro-calcification shown on mammographic X-ray images was associated with the expression of HER-2, molecular typing and axillary lymph node status. The calcification is likely to have no effect on the survival of patients.
ABSTRACT
Objective: Explore photography position of mammary gland molybdenum target X-ray digital image quality. Methods: To choose from June 2011-June 2012 1120 patients for 4320 patients of mammary gland molybdenum target X-ray digital image analysis, image classification statistics of different position of photography, the unqualified reason caused by the image and the influence factors are analyzed. Results: Not class a piece of 292 images in the 4320 images, not percent of pass is 6.76%, unqualified 81 of non-artificial factors, unqualified reason is due to changes in patients mammary gland, unable to obtain high quality images, accounted for 27.74%, improper operation and set 211, accounted for 72.26%, above that are caused by unqualified image after carefully designed rephotography is class a Conclusion:the high quality images needs not only advanced imaging technology equipment and operation, at the same time requires accurate position placement and elaborate design, All three are short of one cannot.
