| Object:The age of breast cancer patients in Liaocheng people’s Hospital in recent years,the application value of breast magnetic resonance imaging in opportunistic screening of outpatients and physical examination of workers in community units.The data collected were compared with mammography and breast ultrasound data collected in recent years.To explore the screening model of breast cancer suitable for Chinese women.To study the clinical value of breast magnetic resonance imaging(MRI)in the treatment of breast cancer.Materials and methods:The first part of the data is based on the data of 1788 breast cancer patients in Liaocheng people’s Hospital from 2014 to 2017,and the patients are divided into five-year and one-year age groups.To observe and analyze the age change trend of breast cancer patients treated in Liaocheng people’s Hospital and the proportion of young patients under40 years old.The second part of the data comes from the physical examination data of workers in Liaocheng people’s Hospital in 2016.All 991 female workers over 40 years of age were examined by magnetic resonance imaging(MRI),all of which were nuclear magnetic fields(MRI).The pathological results and follow-up data were collected and compared with the data of breast cancer screening using different screening methods in other areas reported in the relevant domestic literature,and the results were observed and analyzed as compared with the mammography target.The advantages and disadvantages of breast ultrasound and other examination methods.The third part of the data comes from the breast center clinic of Liaocheng people’s Hospital.From March 2017 to August 2018,1465 people were screened by breast-specific magnetic resonance imaging(MRI)for opportunistic screening.The selected population accorded with the condition of not diagnosed breast-related disease,had high risk factors of breast cancer,genetic factors,pathological signs or strong check-up requirements.The data of all the patients who were able to track the pathological results were statistically analyzed and compared with the results of different screening patterns in other areas of the relevant literature in recent years.To observe the advantages and disadvantages of breast magnetic resonance(MRI)in comparison with other breast examination methods.The fourth part of the data comes from the breast surgery ward of Liaocheng people’s Hospital from March 2017 to August2018 to evaluate the efficacy of neoadjuvant chemotherapy with breast-specific magnetic resonance imaging(MRI).The results were compared with mammography and mammography at the same time.To investigate the value of breast-specific magnetic resonance imaging(MRI)in breast-conserving surgery by collecting relevant literature and clinical data.The fifth part of the data was from March 2017 to August 2018 in all patients who underwent postoperative follow-up with breast-specific magnetic resonance imaging(MRI).The data were analyzed statistically and compared with the related pathological results to explore the significance of breast MRI in postoperative breast cancer follow-up.Finally,the health economics evaluation of different check-up modes was discussed.In this study,Aurora 1.5T special magnetic resonance(dedicated breast magneticresonance imaging DB-MRI(dedicated breast magneticresonance imaging DB-MRI)scanner and breast coil were used to examine the breast magnetic resonance(MRI).Each patient underwent MRI enhancement,and the data were measured and the images were processed by two experienced doctors in breast MRI diagnosis.According to WHO mammography report and data system(Breast Imaging Reporting And Data System,BI-RADS),the morphological features of MRI in plain and enhanced images were described.If a malignant lesion(BI-RADS 4 or 5)was suspected by imaging examination,further examination,including a coarse needle biopsy,was performed.The results showed that the malignant lesions of the breast were followed by further comprehensive treatment of breast cancer.The data obtained by screening were analyzed and analyzed.The sensitivity,specificity,positive predictive value and negative predictive value of breast cancer detected by magnetic resonance imaging(MRI)were analyzed.From March 2017 to August 2018,all patients in the breast surgery ward who used breast-specific magnetic resonance imaging,mammography and mammography to evaluate the efficacy of neoadjuvant chemotherapy were statistically analyzed.Breast MRI was used in breast central outpatients for postoperative follow-up of breast cancer and related pathological results were collected and analyzed.Results:from 2014 to 2017,the number of breast cancer patients diagnosed and treated by Liaocheng people’s Hospital increased year by year.The number of young breast cancer patients under 40 years old showed an increasing trend year by year,but the proportion of breast cancer patients decreased year by year,accounting for about 15%.35 / 65 years old was the age range of high incidence of breast cancer.In 2017,990 female workers over 40 years of age were examined for health in Liaocheng people’s Hospital.The results of the examination showed that there were 12 cases of BI-RADS class 4,of which 4 cases were pathologically diagnosed as breast cancer,and the sensitivity of breast-specific magnetic resonance examination was 100%(4/4).The specificity,positive predictive value and negative predictive value were 99%(978/987),33.3%(4/12)and 100%,respectively.The results of ultrasound and mammography were negative in one case of breast cancer.From April 2017 to August 2018,there were 1465 patients with breast special magnetic resonance opportunistic screening in the out-patient department of breast center of Liaocheng people’s Hospital.The results showed that there were 201 patients with BI-RADS 4 types,of whom 149 patients had pathological results after follow-up,and 80 patients had been diagnosed as breast cancer.The results showed that there were 79 BI-RADS patients in 5categories,72 of them had pathological findings,68 of them were diagnosed as breast cancer,and the detection rate of opportunistic screening with breast-specific magnetic resonance imaging was 10.1%(148/1465).Three types of breast lesions were diagnosed by special magnetic resonance imaging(BI-RADS)and one of them was early breast cancer and the rest were benign breast lesions after minimally invasive circumcision of breast mass in the late stage of the operation.The pathological results showed that one of the patients was early breast cancer and the others were benign lesions of the breast.The sensitivity,specificity,positive predictive value and negative predictive value of mammography were 99.3%(148/149),73.5%(202/275),67%(148/221)and 99.5%(202/203),respectively.The accuracy rate was 82.5%(350/424).Three of the patients who were diagnosed as breast cancer were negative by mammography and mammography after special magnetic resonance examination(MRI)indicated that they needed to be treated and finally diagnosed as breast cancer.3 of the patients were diagnosed as breast cancer by mammography and ultrasonography.There were 4 patients with benign breast lesions diagnosed as BI-RADS 5 by MRI.The pathological results were all inflammatory lesions of breast.From March 2017 to August 2018,60 breast cancer patients were evaluated with breast magnetic resonance imaging in the breast surgery ward of Liaocheng people’s Hospital.Of these,29 completed pre-needle puncture.After the second neoadjuvant chemotherapy and the fourth neoadjuvant chemotherapy,the mammography of mammography was evaluated 4 times before the operation,and the rest of the patients either had poor curative effect due to chemotherapy.Alternatively,a simple mammography or breast ultrasound examination was replaced as a means of assessment.From March 2017 to August 2018,in the breast center of Liaocheng people’s Hospital,the breast region and armpit were reexamined with breast magnetic resonance imaging(MRI),of which 14 patients had BI-RADS grade ≥ 4.After further examination,the recurrence and metastasis of breast cancer were found in 8 cases,of which 3 cases were recurrence and metastasis of breast wall on one side of mastectomy,2 cases were axillary lymph node with recurrence and metastasis on the affected side.Conclusion:The incidence of breast cancer is on the rise in recent years,and young breast cancer patients account for a certain proportion,for young women,breast cancer screening of high-risk groups can not be ignored;Breast magnetic resonance imaging(MRI)can play an important role in community breast cancer screening,physical examination and outpatient opportunistic screening.It has important value in screening breast cancer in young and middle-aged women under 40 years of age and dense glands in young and middle-aged women.To explore a new type of breast cancer screening mode suitable for Chinese women and how to make breast magnetic resonance play a greater role in breast cancer screening of Chinese women needs to be further studied and discussed.Breast magnetic resonance imaging has high application value in neoadjuvant chemotherapy evaluation,preoperative evaluation and postoperative follow-up of breast cancer conserving surgery. |
