ObjectiveTo systematically review the diagnostic value of ultrasound for breast cancer with axillary sentinel lymph nodes, so as to provide evidence for clinical decision-making. MethodsWe searched the databases including PubMed, EMbase, The Cochrane Library (Issue 12, 2013), CBM, CNKI, WanFang Data and VIP for studies about ultrasound in the diagnosis of breast cancer with axillary sentinel lymph nodes till December 31st, 2013. According to the inclusion and exclusion criteria, literature was screened, data were extracted, and methodological quality of the included studies was evaluated. Meta-analysis was then conducted using Meta-Disc 1.4 software. ResultsA total of 12 studies involving 2 188 cases were included. The pooled results of meta-analysis showed that sensitivity and specificity were 0.75 (95%CI 0.72 to 0.77) and 0.91 (95%CI 0.89 to 0.92), respectively; positive likelihood ratio and negative likelihood ratio were 6.54 (95%CI 4.68 to 8.89) and 0.22 (95%CI 0.15 to 0.33), respectively; diagnostic odds ratio was 33.59 (95%CI 17.87 to 63.12); and the AUC was 0.934 3. ConclusionUltrasound is has relatively high value in diagnosis of breast cancer with axillary sentinel lymph nodes. However, due to the influence caused by the limited quality and various potential heterogeneity, more high quality RCTs with large sample size are needed to further verify the above conclusion.
ObjectiveTo explore the scientific method of hospital disease cost management under the disease payment system.MethodsThe data of " breast mass” disease in the case hospital of 2018 were collected, and the cost accounting of the disease was calculated by the income and expenditure ratio method, cost-to-charge ratio method, project-adding method, clinical path method, and activity cost method, respectively. Comprehensive evaluation was conducted for the five methods.ResultsThe direct costs of the disease calculated by income and expenditure ratio method, cost-to-charge ratio method, project-adding method, clinical path method, and activity-based cost method were 3 021.14, 3 387.79, 3 744.45, 3 997.44, and 4 297.18 yuan, respectively, and accounting for 63%, 67%, 70%, 74%, and 80% of total cost, respectively. The standard deviations of direct cost were 514.37, 495.23, 231.22, 317.33, and 197.47, respectively, of which the standard deviation of direct cost of the activity-based costing method was the smallest. The comprehensive scores of key performance indicator of the income and expenditure ratio method, cost-to-charge ratio method, project-adding method, clinical path method, and activity-based cost method were 4.15, 5.40, 7.85, 7.10, and 8.55, respectively.ConclusionsIn terms of the cost results and index evaluation of the disease, the activity-based costing method is the optimal method. The accounting process is close to the real path, which can track the cost drivers, enhance the cost controllability, and is conducive to the management of disease resource consumption.
To investigate the relationship between the serum soluble interleukin-2 receptor (sIL-2R) and the stage and prognosis of breast cancer. Using the method of sandwich ELISA, the preoperative and postoperative sIL-2R in 37 cases of breast cancer was measured, 13 patients with benign disease of breast and 40 normals were also measured. The serum sIL-2R levels in patients with breast cancer were significantly higher than that of the benign disease of breast and the normal controls. The serum sIL-2R about twenty days after operation was significantly lower than that before operation. The sIL-2R in patients with breast cancer was correlative to the clinical stage. The serum sIL-2R in stage Ⅲ patients was remarkly higher than both stage Ⅰ and Ⅱ, its sIL-2R about twenty days after operation remained in a high level. This results showed that expression of the serum sIL2R is correlative to the clinical stage and prognosis of the patients with breast cancer, it can be used as a marker of differentiating the benign from malignant disease of breast.
Objective To study the relationship between metalloproteinases (MMPs) and breast cancer. Methods The literature in recent years on the relationship between the expression of MMPs and breast cancer was reviewed. Results The balance between MMPs and tissue inhibitors of metalloproteinases (TIMPs) is keeping normally kept in human body. Many of the studies showed that the expression of MMPs is increased in breast cancer. Conclusion The growth, invasion and metastasis of breast cancer is closely related with the increased expression of MMPs. This suggests that MMPs is a valuable prognostic marker and TIMPs would be a novel drug against cancer.
ObjectiveTo systematically review the value of the fine-needle biopsies in the diagnosis of benign and malignant breast nodules. MethodsA computer based online search was conducted in PubMed, The Cochrane Library (Issue 7, 2016), EMbase, CBM, CNKI, VIP, WanFang Data databases up to August, 2016 to collect the relevant diagnostic studies of the fine-needle biopsies for benign and malignant breast nodules. Two reviewers independently screened literature, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed using Stata 12.0 and Meta-Disc 1.4 software.ResultsA total of 22 studies involving 24 496 patients were finally included. The results of meta-analysis showed that the pooled Sen, Spe, +LR, –LR, and DOR were 0.95 (95%CI 0.95 to 0.96), 0.96 (95%CI 0.96 to 0.96), 38.27 (95%CI 23.17 to 63.19), 0.05 (95%CI 0.03 to 0.07), 1 031.11 (95%CI 514.19 to 2 067.68), respectively. The AUC of SROC was 0.99 (95%CI 0.98 to 1.00).ConclusionThe current evidence indicates that the FNAC has high diagnostic value in the differential diagnosis of benign and malignant breast nodules.
One thousand four hundred and twenty four patients with breast cancer were treated in our hospital from 1980 to 1993. The authors analysed the clinical date of this patients. The results showed that 1193 patients (84.4%) had menopause after 45 years old, 840 patients (59.4%) had menorrhea more than 30 years, 980 patients (80.5 %) had their first pregnancy after 25 years old, and 912 cases (74.9 %) had no history of breast feed. Breast cancer is related to genetic factors, other breast disease, mental factors and trace elements in human hair. The study of breast cancer and its relative factors can be expected to open a new road for the treatment and prevention of this disease.
ObjectiveTo review recent studies on the roles of estrogen receptor β in breast cancer. MethodsThe literatures in recent years on the biological function, variant isoforms of estrogen receptor and its possible roles in breast cancer were reviewed. ResultsERβ was a new member of the superfamily of steroid receptors, it might play an important role in breast tumor genesis, tumor progression, prognosis and reaction to the endocrine therapy in breast cancer. ConclusionERβ is a new prognostic marker in breast cancer.
Objective To understand the effect of estradiol in different concentrations on proliferation of diverse mammary primary cells in vitro. Methods The primary cells of cancer tissue, the adjacent tissue to tumors and normal mammary tissue from patiens with breast cancer were obtained using collagenase digesting method. All the tissue samples were cultivated in vitro, and were given estradiol in different concentrations. The effect of estradiol on the proliferation of those primary cells was measured by MTT. Results Estradiol remarkedly promoted the proliferation of primary cells of cancer tissue and peritumor tissue in vitro, whose ER expression were positive. Whereas, the promotion effect of estradiol on the proliferation of normal mammary primary cells was relatively weak, and there was no correlation between the promotion effect with the expression of ER in cancer tissue. Conclusion The risks of occurrence and relapse of breast cancer would increase significantly when the concentration of estradiol is no less than 103 pmol/L in vivo.
