Breast screening is a service offered by the NHS to help detect breast cancer and precancerous changes early at a time when treatment is more likely to be curative. An effective service must reach the 'at risk' but asymptomatic population. Breast screening uptake in London, consistently falls below the national target and is well below the national average. Uptake in West London is particularly low, with boroughs in Inner North West London having the some of lowest uptake rates in the country. Routine text message reminders have proven effective at improving uptake of breast screening appointments. However little attention is paid to the content of the messages. Previous studies of text message reminders in other clinical areas have shown that the content of these messages matters and some text messages are more effective than others. This protocol describes the design of a randomized controlled trial to investigate the effect of differently worded text messages on the engagement with breast screening in West London. Two intervention arms were designed taking into consideration results of a 1000 woman survey to highlight the behavioural barriers that most predict attendance. The survey tested 15 behavioural constructs and the two that most strongly predicted history of attendance were used to inform the text message content of the intervention arms for this trial. To this end, this randomised controlled trial (RCT) will test the current standard practice text message reminder against two intervention text message trial arms informed by the above described survey. The setting is West of London Breast Screening Service and women aged 47-73 who are due for screening will be randomized to receive one of the three trial arms. The primary outcome is the difference in uptake between trial arms. Further statistical analysis will analyse the difference in uptake by age group, deprivation score and previous attendance status. Result will inform how small changes to the word content may have significant effects on attendance at screening mammogram appointments.
About a third of patients with breast cancer are usually treated by hormone pills called tamoxifen and aromatase inhibitors. Aromatase inhibitors are drugs that stop female hormone production. Female hormone or estrogen is an important hormone for the growth of breast cancer cells. Letrozole is one of the aromatase inhibitors that is approved by the FDA and has been used to treat breast cancer since 1997. However, hormone pills usually work for about 6-10 months in most patients. Later on, breast cancer will start to grow again. This condition when hormone pills or endocrine therapy no longer work is called "endocrine resistant" breast cancer. The scientists here at University of Maryland have discovered how these cancer cells can become resistant to hormone pills. In our laboratory tests, the investigators found that lapatinib and everolimus can reverse this resistance and make letrozole work again. However, it is not known if the drugs can reverse the resistance in humans. The purpose of this study is to find out whether the combination of letrozole, lapatinib, and everolimus is effective in women with breast cancer when hormone pills no longer work. Lapatinib is an anti-cancer drug that is already approved by the Food and Drug Administration (FDA). It is the standard of care for the treatment of a particular type of breast cancer called human epithelial growth factor receptor 2 (HER2)-positive breast cancer. HER2 is a protein involved in the growth of some cancer cells. This study will also include patients with HER2-negative breast cancer. This means that the cancer cells in these patients do not depend on the HER2 protein. The use of lapatinib in these patients is considered experimental. Everolimus is also an anti-cancer drug that is approved by the FDA for kidney cancer. Initial studies in mice and later studies in women with breast cancer have shown that everolimus may also slow the growth of breast cancer. The use of everolimus is experimental in this study.
In this study, participants, who are scheduled to have a breast biopsy, will have several extra spot mammogram images taken of the suspicious area. These images will be acquired with varying levels of compression. The images will then be analyzed to determine whether the type of lesion (malignant or benign) can be determined from the image data alone. The biopsy results will be used as a gold standard to determine the true malignancy status
The study will determine the sensitivity, specificity, negative predictive value and positive predictive value of the OSNA Breast Cancer System for patients receiving Sentinel Lymph Node biopsies after receiving neoadjuvant hormonal/chemotherapy as compared to permanent section Hematoxylin and Eosin (H&E) and Immuno-histochemistry (IHC) staining.
