Filter by:Metformin is an anti-diabetic oral hypoglycemic agent that considered the gold standard therapy for the treatment of type 2 diabetes. Retrospective analyses show that metformin can offer therapeutic benefits to patients with several forms of cancer. It also has positive weight reducing effect on non-diabetic patient by improving insulin sensitivity (although the exact underlying pathomechanisms remain to be elucidated).
This trial is an open, multi-center, phase Ic clinical study on the pharmacokinetics and drug interactions of utidelone injection combined with capecitabine in patients with recurrent and metastatic breast cancer. The purpose of this trial is: 1. To evaluate the pharmacokinetic characteristics of continuous intravenous administration of utidelone. 2. To evaluate the drug interaction of utidelone and capecitabine.
CDK 4/6 inhibitors (palbociclib, ribociclib) have taken their place in our practice recently with their clinical benefits in the treatment of hormone-positive and HER2 negative metastatic breast cancer. Abemaciclib, another CDK 4/6 inhibitor, is not frequently preferred because of reimbursement problems in Turkey. The most obvious advantages of CDK 4/6 inhibitors are that they are used orally and have relatively fewer side effects against chemotherapy. Neutropenia, diarrhea, elevation in liver function tests are the main dose-limiting side effects. In the geriatric age group, it can be thought that the expected benefit from the treatment will not be achieved in cases where these side effects cannot be predicted or managed well. The geriatric age group (65 years and older) deserves special attention in oncology practice, considering both the treatments and the disease itself. Although a number of very useful clinical scales have been developed regarding this subject, it is important that the scale used should be comprehensive as well as being easily applicable for integrating it into daily practice. Geriatric 8 (G8) was found to be a highly sensitive test based on a comprehensive geriatric examination, while the Groningen frailty scale with high specificity. The common feature of these two tests is that they are suitable for daily practice as they are easy to fill. In the light of this information, we aimed to examine whether the G8 and Groningen frailty scale could shed light on clinicians in predicting side effects during the use of CDK 4/6 inhibitors (palbociclib and ribociclib) in geriatric breast cancer patients. We also aimed to reveal the adverse events of these CDK 4/6 inhibitors as real-life experience.
The central goal of this study is to test strategies to implement evidence-based breast cancer risk assessment in healthcare clinics in Tennessee. The BRAVE Strategy (Breast cancer Risk Assessment - achieVing Equity) study aims to assess the feasibility, reach, acceptability, and appropriateness of select customized strategies to increase uptake of breast cancer risk assessment. The investigators will achieve these aims through a conducting a stepped-wedge trial conducted in 10 healthcare clinics in the state of Tennessee. The primary outcome is the proportion of women age 25-49 having risk assessment. Secondary outcomes include the numbers of 1) women identified as high-risk; 2) pursuing risk-adherent screening; and 3) diagnosed with breast cancer.
This is a cohort, single-center, prospective study that seeks to analyze the circulating tumor DNA (ctDNA) in patients diagnosed with breast cancer, who will undergo neoadjuvant treatment.
This study collects information and identifies decision making needs for older adult women with stage I-III breast cancer considering neoadjuvant and adjuvant chemotherapy. Using this information, a decision support tool is then developed to provide patients and physicians with tailored information regarding the risks and benefits of chemotherapy and values clarification to support high-quality, shared decision. Subsequently, the decision support tool will be tested amongst older patients with early-stage breast cancer and health care providers navigating the decision process around chemotherapy, and further refined through an iterative process.
Breast cancer is the most frequently observed cancer in women in France.The mortality rate is still decreasing with a decrease of 1.6% per year between 2010 and 2018, explained by the improvement in available treatments.For patients with breast cancer expressing hormone receptors, treatment with Tamoxifen or anti-aromatase can have the risk of the cancer coming back.However, these treatments have many side effects, including the risk of osteoporosis and metabolic disorders with anti-aromatases; and arterial and thromboembolic accidents with Tamoxifen.These effects have been well studied while taking hormone therapy.However, very few studies have analyzed the impact of these treatments after stopping them in women who have had non-metastatic hormone-sensitive breast cancer and uncertainties persist on the evolution of the health risk after initial treatment.
Female breast cancer is the most common cancer and fifth leading cause of cancer death worldwide. In the past decade, breast cancer consistently to be the most common cancer for women in Hong Kong, so much that it accounts for 27% of all female cancers, with 4,600 new cases of breast cancer registration every year and the lifetime breast cancer risk for females is 1 in every 14. At the same time, breast cancer ranks the third in cancer death in Hong Kong, with a five-year relative survival rate of 84%. Regular mammography screening has been shown to reduce the mortality of breast cancer. International guidelines recommend annual or biannual mammography screening for women aged 50 or above. The adherence to regular mammography screening remains a challenge. Studies had shown that the adherence decreased over time. Mailed and telephone reminder were being proven to be effective tools to increase the adherence to regular breast screening using mammography. However, both mailing and telephone strategies are associated with labor intensity and high cost. Over the past two decades, the advent of internet and smartphone provided a fertile platform for the development of mobile-health technologies. WhatsApp Messenger is one of the most frequently used free-of-charge mobile messenger that permits users to send secure messages across different device platforms. A recent randomized controlled trial from our team has suggested its clinical utility in improving adherence to regular colorectal cancer screening using fecal immunochemical test. This encouraging data prompted us to investigate the potential role of WhatsApp Messenger in breast cancer screening. We hypothesized that text reminder sent via WhatsApp Messenger improves the longitudinal adherence to biannual mammography in a community-based, opportunistic breast screening program.
Majority of breast cancer survivors are overweight or obese at time of diagnosis, putting them at increased risk for insulin resistance and Type 2 Diabetes Mellitus (T2DM). Women with insulin resistance at time of breast cancer diagnosis often have larger tumors, later stages of cancer and worse prognosis. Additionally, chemotherapy often leads to increases in insulin resistance and cognitive impairment. Many cancer survivors experience memory and brain function decline following chemotherapy that can last for years, and insulin resistance may contribute to worse cognitive outcomes in cancer survivors. Omega-3 polyunsaturated fatty acids (PUFAs) are anti-inflammatory nutrients that may help reduce insulin resistance and negative cognitive outcomes from cancer treatments. The purpose of this observational study with cross-sectional design is to investigate the relationship of omega-3 PUFAs with insulin resistance and cognitive function in obese breast cancer survivors. Due to the global pandemic caused by the coronavirus disease of 2019 (COVID-19), this study will be conducted entirely remotely using electronic data collection and remote finger-stick blood sample collection. The study will aim to enroll 80 racially and ethnically diverse female breast cancer survivors (age 45-75) who are postmenopausal, and 1 to 4 years post breast cancer diagnosis. Participants will complete study questionnaires online, and some cognitive tests will be completed through zoom sessions with trained study personnel. Participants will be mailed kits with thorough instructions to complete fingerstick blood sample collections and mail them back to the research lab. Upon receipt of blood samples and completion of all study questionnaires, participation will be complete.
The purpose of this observational study is to assess whether the use of AI (Transpara®) can lead to an improved quality of a double reading mammography screening program. This is investigated by performing AI as a third reader and as a decision support during the consensus meeting, compared with conventional mammography screening (double reading and consensus without AI).
