e12091 Background: With the rapid development of MRI scanning technology , DCE-MRI in breast cancer has been one of the most sensitive examinations for the reason of allowing precise imaging, which can be helpful to demonstrate and evaluate the anatomical structures of breast cancer and its surrounding. What is more,through application of postprocessing technique of MRI,quantitative and half-qualitative data can be obtained for the diagnosis and the differential diagnosis of breast cancer. It is reported that the recurrence of breast cancer after breast conserving surgery is related with elevated BEC of MRI before operation as the result of the difficulty to find the micro-lesions and the margin of infiltrative lesions. Objective: Study on the relationship between the background enhancement coefficient of breast cancer under MRI before operation and recurrence of postoperative chest wall. Material and Methods: 194 cases of breast cancer patients undergoing radical surgery were retrospectively analyzed, all of which were confirmed by pathology and molecular classification.Before surgery all the patients did MRI and the BEC was measured.Aim for study on the relevance of the elevated BEC and chest wall recurrence,we investigate the relationship between the stage, grade,molecular subtype of breast cancer and the elevated BEC statistically. Results: The elevated BEC of the breast before operation is associated with chest wall recurrence after operation (P=0.045), and high expression of HER-2 (P=0.07). Multiple lesions of breast cancer and Ki-67>14% also appeared to be associated with the elevated BEC (P=0.08).While there seem to be no correlation between the size of tumor ,LN metastases, nuclear and pathological grade,molecular typing, PR expression,ER expression, status of the LN capsule and the elevated BEC. Conclusions: The elevated BEC of breast before operation is an independent prognostic factor for chest wall recurrence after operation.Given BEC get a potential to make a brand new biomarker for breast cancer,further relevant research is needed.

Background: CASC15, one of long non-coding RNA, is involved in the regulation of many tumor biological processes, and is expected to become a new biological therapeutic target. This paper aims to elucidate the pathophysiological function of CASC15 in various tumors. Methods: The relationship between CASC15 and tumors was analyzed by searching references, and summarizes the specific pathophysiological mechanism of CASC15. Results: LncRNA CASC15 is closely related to tumor development, and has been shown to be abnormally high expressed in all kinds of tumors, including breast cancer, cervical cancer, lung cancer, hepatocellular carcinoma, gastric cancer, bladder cancer, colon cancer, colorectal cancer, cardiac hypertrophy, intrahepatic cholangiocarcinoma, leukemia, melanoma, tongue squamous cell carcinoma, nasopharyngeal carcinoma. However, CASC15 has been found to be downexpressed abnormally in ovarian cancer, glioma and neuroblastoma. Besides, it is identified that CASC15 can affect the proliferation, invasion and apoptosis of tumors. Conclusion: LncRNA CASC15 has the potential to become a new therapeutic target or marker for a variety of tumors.

Melatonin Production

In this review we summarize a possible connection between gut microbiota, melatonin production, and breast cancer. An imbalance in gut bacterial population composition (dysbiosis), or changes in the production of melatonin (circadian disruption) alters estrogen levels. On the one hand, this may be due to the bacterial composition of estrobolome, since bacteria with β-glucuronidase activity favour estrogens in a deconjugated state, which may ultimately lead to pathologies, including breast cancer. On the other hand, it has been shown that these changes in intestinal microbiota stimulate the kynurenine pathway, moving tryptophan away from the melatonergic pathway, thereby reducing circulating melatonin levels. Due to the fact that melatonin has antiestrogenic properties, it affects active and inactive estrogen levels. These changes increase the risk of developing breast cancer. Additionally, melatonin stimulates the differentiation of preadipocytes into adipocytes, which have low estrogen levels due to the fact that adipocytes do not express aromatase. Consequently, melatonin also reduces the risk of breast cancer. However, more studies are needed to determine the relationship between microbiota, melatonin, and breast cancer, in addition to clinical trials to confirm the sensitizing effects of melatonin to chemotherapy and radiotherapy, and its ability to ameliorate or prevent the side effects of these therapies.

Abstract Background The number of e-health interventions developed for breast cancer survivors continues to increase. However, issues with engagement and retention are common. This study aimed to explore e-health literacy rates and access to smartphones and tablets in a large sample of breast cancer survivors. Methods In study 1, women were recruited from outpatient breast clinics across England and Wales. Eligible women were asked to complete a questionnaire pack to assess their access to devices and their e-health literacy. Multiple regression analyses were run to assess the relationship between technology access and e-health literacy with sociodemographic variables such as age, social deprivation, and education. Study 2 presents a smaller sample recruited through social media who answered a questionnaire relating to use of mobile devices and e-health, and apps. Results Two thousand nine women participated in the study. Seventy-one percent had access to a smartphone, 54% had access to a tablet, and 20% did not have access to either device. Multiple logistic regressions showed that women who were younger, had higher levels of education, and who were from less deprived areas were more likely to have access to either device. Poorer e-health literacy was associated with being older, having less education, and not having access to a mobile device. Conclusions Whilst the results show relatively widespread access to mobile devices, there is evidence of a digital divide across some groups. Online interventions should be developed with consideration of individuals who are less e-health-literate and less technologically adept in order to increase the likelihood of engagement.
