ABSTRACT
Objective To investigate the value of correction of ultrasound elastography strain rate ratio in BI-RADS grading of breast hyperplasia with fibroadenoma and breast cancer.Methods The data of 120 cases of hyperplasia of mammary gland hyperplasia with fibroadenoma and 120 cases of breast cancer confirmed by operation or biopsy in this hospital from January 2012 to October 2016 were analyzed retrospectively.The boundary,shape,echogenicity,aspect ratio,calcification,blood flow distribution,resistance index,BI-RADS grade,ultrasonic elastography strain ratio were analyzed.The value of correction of ultrasound elastography strain rate in breast hyperplasia with fibroadenoma and breast cancer BI-RADS grading ratio were investigated.Results There were significant differences in boundary,rear echo,aspect ratio,calcification,ultrasonic elastography strain ratio between breast hyperplasia with fibroadenoma and breast cancer (P＜0.05);There was no significant difference between the two groups about morphology and internal echo (P＞0.05);Breast hyperplasia with fibroadenoma were mainly 0-Ⅰ in blood flow distribution,RI＜ 0.7,breast cancer showed Ⅱ-Ⅲ,RI≥0.7,the difference was statistically significant (P＜0.05).Ultrasound elastography strain rate ratio improved the diagnose accordance rate of two groups after BI-RADS' classification correction.Conclusion Hyperplasia of mammary glands with fibroadenoma and breast cancer have overlapping ultrasound features.Ultrasound elastography strain rate ratio can improve the diagnose accordance rate of two groups after BI-RADS' classification correction,which has certain clinical value.
ABSTRACT
Objective To investigate the relationship between mammary ductal hyperplasia and ductal carcinoma by detecting the expressions of Notch1 and Cyclin D1 in various histotypic mammary ductal diseases.Methods A total cases of 44 normal ductal tissues,44 usual ductal hyperplasias.40 atypical ductal hyperplasias,42 ductal carcinomas in situ and 51 invasive ductal carcinomas were included in this study.Expressions of Notch1 and Cyclin D1 were detected by S-P immunohistochemistry.Results There was significant difference of expression of Notch1 among the five subgroups of this study(P<0.01);there were significant differences between every two subgroups(P<0.05)except for normal ductal tissues versus usual ductal hyperplasias and ductal carcinomas in situ versus invasive ductal carcinomas(P>0.05).There was also significant difference of expression of CychnD1 amongthe five subgroups of this study(P<0.01),and there were significant difference between every two subgroups(P<0.05)except for normal ductal tissues versus usual ductal hyperplasias and normal ductal tissues versus atypical ductal hyperplasia(P>0.05).The correlation between Notch1 and Cyclin D1 was negative (r=-0.428,P<0.01).Conclusions There is a relationship between mammary ductal hyperplasia and ductal carcinoma.Decrease of Nowhl or increase of Cyclin D1 expressions may promote nmnmmry ductal hyperplasia advancing to manunary ductal carcinoma.
ABSTRACT
Se realizó un estudio longitudinal, prospectivo observacional en 30 pacientes que acudieron a la consulta externa del servicio de cirugía general del Hospital Militar Clínico Quirúrgico Docente "Octavio de la Concepción y de la Pedraja", en el primer semestre del año 2000 con el diagnóstico clínico de alteración fibroquística de la mama; a las cuales se les aplicó tratamiento con Tamoxifeno 10 mg / por vía oral diario, durante tres meses. Todas las pacientes que conformaron la muestra cumplían dos premisas fundamentales: a) haber procreado, b) rango de edad entre 25-35 años. La efectividad del tratamiento a los tres meses fue excelente, no se observaron efectos adversos.
A longitudinal, prospective - observational study was carried out in 30 patients who attendet to the external consultation of general surgery at " Octavio de la Concepción y de la Pedraja" Miltary - Clinical- Teaching Hospital during the firts semester of 200 with the clinical diagnosis of fibrocystic disease of breats: to whorn a treatment whit tamoxifen 10 mg/ orally/ day during three months was applied . All patients participating in the sample fulfill two main premises: a) to have procreated, b) age group among 25-35 years. Treatment effectiveness after three months was excellent, adeverse effects were not reported. Literature is received.
ABSTRACT
Objective To observe the therapeutic effect of Qingxiang Concentrated Pill (QCP) on mammary gland hyperplasia (MGH) in rats. Methods Injection of estradiol were given to establish rat models of MGH and QCP was given QCP at the same time. Pathologic changes of mammary gland in rats were observed under light microscope. Changes of breast diameter, mammary gland volume and weight were measured; serum sex hormones levels, SOD activity and MDA content were also estimated. Results QCP could decrease the increased breast diameter, mammary gland volume and weight, reduce the numbers of mammary gland lobules and mammary acini and the diameter of acinar cavities. It could also decrease eatradiol level and MDA content in serum, inhibit the decrease of the coefficient of thymus and increase the serum progesterone level. Conclusion QCP can regulate sex hormone levels, inhibit lipid peroxidation and relieve the pathologic changes of mammary gland in MGH rats.
ABSTRACT
Objective To analyse the necessity and feasiblity about the diagnosis and classification of fibrocystic disease of breast, through using synthesize imaging methods.to increase the diseases diagnosis rate. Methods Using imaging checks (molybdenum photography,ultrasonography and infra - red scanner) for 600 breast's cases and contrast to pathogenesis if they were done operations. Results 143 cases were normal. 166 cases got other disease of breast,291 cases were fibrocystic disease of breast(48. 1%), 155 cases of them were performed operations and pathogenesis. the diagnosis similar rate between performed operations check and pathogenesis was 83. 2%. Conclusion The sensitivity of three kinds imaging check method is different each other,but one method can give some help each other. The synthesize imaging check can increase the diagnosis rate and avoid mis - diagnosis and doing needless operations.
ABSTRACT
Objective To expatiate the ultrasonographical and pathological manifestations of breasts with juvenile macromastia.Methods Four patients with juvenile macromastia were examined by high frequency ultrasonography.The sonographical and pathological images were observed and reported.Results The sonographical characteristics of the breasts with juvenile macromastia were similar: the anatomical structures of the breasts were obscure,which were characterized by cystic formation,reticular structure,patched hypoechoic or hyperechoic regions and distorted gland structure.One patient had fibroadenoma and dermatic erythema.The results of pathological examination showed marked cystic proliferation of glands accompanied with ductal epithelial hyperplasia,irregular ductal distribution,no lobules formation or proliferation of fat tissue,fibrocyte and fibroblast.Conclusions The abnormalities of juvenile macromastia may not only be the huge volume,but also may include abnormal ultrasonographical and pathological manifestations,awaiting more follow-up studies.
