Filter by:This project aims to investigate the role of MMA in breast cancer. To this end, we will measure MMA on serum samples collected at the time of breast cancer diagnosis, to investigate the role of MMA in predicting long-term recurrence risk, response to neoadjuvant chemotherapy, and its association with age and clinical frailty.
At present, there are no FDA-approved treatments for chemotherapy-induced neuropathy. Discrete neuro anti-inflammatory effects of metformin support its repurposing as a neuroprotective agent in patients with neurodegenerative diseases. Therefore, this study aims to evaluate the effect of metformin on the amelioration of paclitaxel induced neuropathy in cancer patients.
This study aims to investigate the possible role of rosuvastatin in protection against cardiotoxicity in HER2 positive breast cancer patients receiving doxorubicin sequential with trastuzumab.
This is an early research and development study. The objective of this study is to determine the feasibility of the Imagio OA/US Breast Imaging System to detect complete breast cancer pathologic response to neoadjuvant therapy as assessed by functional optoacoustic features, vascular features and relative degrees of oxygenation/deoxygenation
Breast cancer (BC) is the most common malignant disease, which is fifth leading cause of cancer mortality worldwide. Poor nutritional status is one of the common physical symptoms found among cancer patients, in which it is caused by both cancer disease state and its oncology treatment regimens used. Cancer patients develop a tumor-associated malnutrition characterized by an insufficient supply of macro- and micronutrients and systemic chemotherapy treatment that could significantly affecting the nutritional status of these patients by its side effects associated with chemotherapy that may lead to many medical complications that often requires hospitalization and death. An adequate nutritional intervention can have a beneficial impact on the disease condition and also the progress of the disease, as an integral part of adjuvant therapy on cancer care. Numerous studies had shown that the use of EPA and DHA are safe (absence of cardiotoxic effects) and effective in reducing the common chemotherapy-related side effects, such as bone density loss, peripheral neuropathy and weight gain. The question remains arises to whether administration of both vitamin D and omega-3 fatty acids supplementations could be used as important nutritional strategy during the active oncology treatment in breast cancer patients. In Palestine, nutritional intervention strategies are poorly evaluated in the oncology setting especially among patients undergoing chemotherapy. Suitable and proper nutritional interventions among breast cancer patients during active oncology treatments could help to improve nutritional status, decrease mortality and improve quality of life among these subjects. Hence, the present study is formulated to assess the effect of combined omega-3 fatty acid and vitamin D supplementation on the nutritional status, quality of life and blood inflammatory markers among breast cancer women undergoing chemotherapy treatment in the Gaza Strip, Palestine.
Breast cancer is the most common cancer in women and also has the highest death rate. In 2018, 58,500 new cases were diagnosed in metropolitan France. It affects, in 8 out of 10 cases, women aged 50 and over. Nevertheless, thanks to early detection and improved therapeutic techniques, its mortality rate has continued to decrease each year (a decrease of 1.6% per year was recorded between 2010 and 2018), which allows it to maintain its status as a cancer with a good prognosis. Furthermore, net survival is 87% at 5 years and 76% at 10 years. The median age of death is 74 years. Organized screening was initiated in France in 1990 and generalized in 2004, while maintaining a specific management according to the personal risk of each patient. It consists of a mammogram, plus or minus an ultrasound, every two years from the age of 50. The mammogram is reviewed by two different radiologists. In case of abnormality, a biopsy is performed. Breast lesions are separated into two nosological entities: palpable tumors, often diagnosed on clinical examination (or autopalpation) and confirmed on mammography, and non-palpable tumors detected during mammographic and/or ultrasound screening. Thanks to the generalization of screening, the detection of subclinical lesions requiring surgery represents more than half of the breast surgeries and the challenge of their surgical management lies in a precise preoperative location to allow a complete removal, while limiting the sacrifice of healthy glandular tissue. The metallic location technique is currently the reference technique for the preoperative location of these lesions. For all these reasons, new techniques of preoperative tracking have been developed. Magnetic tracking (MR) appears to be a simple, non-radioactive and non-aggressive technique to use and organize. MR takes the form of a 1x5mm paramagnetic clip made of iron oxide visible on ultrasound and mammography and is detected by a SentiMag probe. The MR began to be used in France in 2017. It is placed in contact with the lesion under ultrasound guidance. It has the advantage that it can be placed up to 30 days before surgery and has less risk of complication. This MR contains iron particles and is 5mm long. It is pre-loaded in a sterile 18 G needle closed with a wax tip. It is deployed under mammographic and/or ultrasound guidance. The Sentimag probe is used to detect MR in a multidirectional way at 360°, with an audio and visual estimation of the distance. It generates an alternating magnetic field that magnetizes the iron in the MR. All of these surgical procedures can be performed as outpatient surgery, which corresponds to a hospitalization of less than 12 hours without overnight accommodation, meaning that each patient is admitted and discharged on the same day as her procedure. Outpatient surgery represented 36% of all surgeries in France in 2018. The objective of the HAS is to achieve a majority ambulatory practice of 70% by 2022. This type of surgery has advantages for the patient, by making her journey safer: reduction in the risk of nosocomial infection, thromboembolic risk and anxiety linked to hospitalization for the patient and her family. It also has an important socio-economic advantage by reducing hospitalization costs and the number of hospital beds required. It improves the working conditions of the staff by reducing the workload and night shifts. It has also enabled a clear improvement in the optimization and efficiency of the organization of resources in the surgical technical platforms. The role of the MR is particularly well suited to this new organization.
The purpose of this study was to evaluate the effectiveness of additional ramosetron injection for controlling late postoperative nausea and vomiting (PONV) after breast surgery in high risk PONV patients. The investigators compared PONV amomng 3 groups- group C: no additional ramosteron, group B: two additional ramosteron doses at 12 hour interval, group M: two additional ramosetron doses mix to the intraveonus patient controlled analgesia.
Tamoxifen and aromatase inhibitors are two oral hormonal therapies (OHT) that decrease the risk of breast cancer recurrence by over 30 %. Their efficacy however strongly depends on the duration of use (5 to 10 years). Earlier work demonstrated that the longer an individual is not taking her OHT the less likely she is to restart her therapy. Thus, identifying the moment of treatment interruption in real-time and being able to contact the patient at these specific time-points may be the key to effective health interventions by improving medication adherence to reduce BC recurrence - therefore, increasing overall Breast Cancer survival (BCS). EHealth technologies may be a very effective mean to identify these interruptions in a real-time manner and to provide support at the time the person needs it. The overall aim of the E-dherence Pilot study is to evaluate the feasibility of the E-Health intervention to enhance OHT adherence in BCS. Feasibility is defined based on 1.The eHealth intervention acceptability, 2. eHealth intervention quality and 3. medication adherence. The study will include female breast cancer starting their first prescription of tamoxifen or aromatase inhibitors and are outpatient and followed-up in either of the 2 study sites. Participants should be 18 years or older and be fluent in french and or German and possess a smart-phone (iOS, Android). The investigators exclude males, patients with in situ metastatic tumors, inpatients and non Luxembourg residents. Within the E-dherence Pilot study each patient receives the eHealth intervention. The eHealth intervention consists a Medication Event Monitoring Systems (MEMS®) Helping Hand and MEMS Adherence Software application. The eHealth intervention will support BCS to adhere to the recommended OHT (i) by alerting the participants to take their OHT, and (ii) by allowing patient-physician communication. The intervention consists of a Medication Event Monitoring Systems (MEMS®), an electronic pillbox that counts the OHT intake, the date and time. Through Near Field Communication (NFC) the device is connected to the MEMS Adherence Software application on the patients' phone (Android or iOS). At the beginning, each patient can personalize the application. This application registers the history of OHT adherence (time and date of medication intake) and sends reminders to the patient to take the treatment as scheduled. Additionally, the patient receives an integrated calendar in the App that notifies the patient for upcoming medical visits. The eHealth intervention comprises a questionnaire that should be filled-out weekly and that informs about the presence and severity of side effects. These data are collected in real-time and monitored on a weekly basis by the clinical research nurse (CRN) in charge of the study. In case of an alert, meaning recurrent non-adherence and/or reporting of side-effects, the CRN will contact the breast cancer nurse (BCN) in charge of the patient. Thus the BCN will contact the patient by phone to check on their health status and together define the future procedure in order for the patient to remain on OHT and/or to better manage their side-effects. In a worst case scenario, the BCN will refer the patient to see the emergency department and/or the oncologist. The study received all ethical approvals.
The study recruits breast cancer survivors who are already on chemotherapy or are going to start chemotherapy. Subjects will be asked for their preference to attend physiotherapy and educational class (for intervention group) or decline for it (for control group). For intervention group, subject will attend 24 sessions of physiotherapy (exercise class) and 10 sessions of educational class over 12 weeks. The supervised 1-hour group exercise class will be conducted twice a week. Educational class will be once a week, with topics covering physical activity, management of fatigue, lymphoedema, neuropathy, brain fog, return to work, stress, nutrition, sexuality, psychosocial and caregiver issues. Subjects in control group will be asked to exercise on their own in the 12 weeks. 12 weeks later, all subjects will attend a 2-hour survivorship transitional class, with topics covering cancer surveillance and follow up, addressing fear of recurrence: symptom and support, neuropathy/ fatigue/physical impairment/ brain fog, physical activity and diet, screening for colorectal and cervical cancers, return to work and community resources. During the class, a screening questionnaire will be administered to identify further physical, rehabilitation and psychosocial needs and to triage these patients to relevant hospital and community services. Outcome assessment will be done at pre-intervention, after intervention, 6 months and 1 year after the intervention.
Targeted therapy in the treatment of breast cancer targets HER2 receptor (Human Epidermal growth factor Receptor). HER2 receptor plays an important role in cell growth and differentiation (5). However, when HER2 overexpresses, it may lead to cancer. HER2 positive malignance exacerbates pathology and worsens clinical outcome, such as shortened overall survival (OS) compared with non-HER2 overexpression patients (6), (7). About 20-30% overexpression HER2/neogene breast cancer patients and patients having HER2 overexpression tumor have disease progression and poor prognosis in metastatic process (8), (9). Currently, targeted therapeutic, which attaches to the HER2 receptor, inhibiting the growth of cancer cells has been approved. One of these products is Trastuzumab. The study processed on 50 females aged between 18 and 65, recurrent or metastatic breast cancer patients with positive HER2. The subjects were randomly distributed in 2 groups as NNG-TMAB + docetaxel or Herceptin® + docetaxel, in blocks of 4 in a 1:1 ratio (NNG-TMAB: Herceptin®). In each block of 4 will be 2 patients in the experimental group and 2 patients in the control group. Primary endpoint is serum peak concentrations (Cmax), area under the curve from 0 to t (AUC0-t). This trial is intended to assess the biosimilarity of pharmacokinetic parameters, safety between Faceptor (experimental drug) and Herceptin (reference).
