Plant Sterol INtervention for Cancer Prevention (PINC)

Several types of human cells convert cholesterol into other molecules, including oxysterols. Oxysterols can promote breast cancer growth and help tumours to spread. Some breast cancer types recruit other cells (host cells) able to produce oxysterols within the local cancer environment. How these other cells help breast tumours metastasize or resist chemotherapy is not well understood, but epidemiological and clinical studies suggest elevated LDL-C is associated with worse survival, poorer response to therapy and an increased propensity for disease relapse in breast cancer patients. In this trial the investigators will test how an LDL-C lowering dietary intervention (using commercially available phytosterol added food products), alters the ability of non-cancer cells (adipocytes, fibroblasts and macrophages) collected from high LDL-C volunteers to change chemotherapy response and metastatic process in breast cancer cells. In this trial, volunteers with high LDL-C levels will be recruited by the University of Leeds, and divided randomly into two arms that cross over. The experimental period (yogurt drink enriched with phytosterols) and placebo period (non-enriched yogurt drink) will each last for 8 weeks, alternated with a 4 weeks of wash-out period. Samples will be collected 4 times (week-0, week-8, week-12, week-20) during the study and will include blood, white blood cells (macrophages), and fat tissue cells. Measurements will include oxysterol, LDL-C and phytosterol concentrations (volunteers' serum/plasma, media from the host cells/breast cancer experimental culture) and how the host cells alter the behaviour of cancer cells in the laboratory.

Pain Monitoring After Breast Biopsy: Benefit of E-health

Each year, approximately 1500 breast biopsies (1000 microbiopsies and 500 macrobiopsies) are performed in the radiologic department of the Montpellier Cancer Institute (ICM). This exam, which is relatively easy for the radiologist, can however lead to major anxiety for patients. Indeed, previous studies show that about 50% of women undergoing a breast biopsy have significant anxiety affects. Anxiety associated with the risks of biopsy, potential breast cancer diagnosis and/or lack of routine sedation procedures increase patient concerns. Distress prior to biopsy is associated with greater pain and discomfort during the procedure. The psychological distress that persists after the biopsy is related to a worse psychological management of side effects of the biopsy breast (e.g., sensitivity, skin irritation). Limiting apprehension, worry and anxiety induced by the uncertainty linked to the biopsy results and the biopsy-related pain should be an integral part of the medical care through the patient follow-up during, after and until the diagnosis is announced. In light of these challenges, new alternative methods are emerging to enhance patient knowledge, develop procedural skills, improve confidence and mitigate procedural anxiety. However, to our knowledge, few methods have been developed during this period of 'waiting-time'. Currently, only care instructions and a consultation to announce the results (about 10 days after the procedure) are proposed to patients at the end of biopsy. Patients are also encouraged to call if they suspect complications such as infection or bleeding. In this context, the investigators propose to integrate a pain management after biopsy via e-health system through the patient's medical care. Radiologist/patient communication could have an impact on patients' anxiety and health-related issues, given the challenging nature of discussions around need for breast biopsy and potential implications of the results. Indeed, paying attention and focusing on symptoms as patients experience them improves their empowerment and their adjustment to the disease. Web-based systems that can provide electronic-Patient reported Outcomes (e-PRO) have been shown to prompt clinicians to intensify symptom management, to improve symptom control and to enhance patient-clinician communication patient satisfaction, as well as well-being. In addition, it is known that improved communication between patients and medical staff to less anxiety after a biopsy and that anxiety is related to pain. Taken as a whole, these elements encourage the integration of e-health and e-PRO for the management of pain and anxiety in patients undergoing a biopsy. The benefits of e-PRO are still being discussed in terms of quality of life (Qol) and psychological distress. The investigator propose to integrate two types of e-health intervention: 1/e-PRO collected by connected objects (smartphone or tablet) as they were used in previous studies, and 2/ e-PRO collected by a phone consultation, which values human communication between the medical staff and the patient. In case of significant pain, the collection of e-PRO by any of these e-health interventions will generate an alert and a reactive and responsive care. In fine, the purpose of this research is to improve the medical organization and care of post-biopsy patients by proposing an innovative connected patient technology, regardless of their remoteness from the hospital. Social inequalities will be reduced by lending a tablet to patients who do not have such a device with a 4G key.

Memory Perception Assessment in Central/Non-central Nervous System Cancers

Prospective memory (PM) is the ability to implement intended actions in the future. It allows maintaining and retrieving future plans, goals, and activities (i.e., remember to remember). PM is associated with most everyday memory problems . PM is crucial to correctly respond to all the social, occupational and working demands of everyday life, to perform many deferred health-related actions and is involved in therapeutic adherence . Indeed, PM errors are an important part of the aging memory complaints. The prevalence of self-reported PM failures is also significant among young adults, compared with self-reported retrospective memory (RM) failures .Yet, PM errors are major sources of frustration and embarrassment . In oncology, recently investigated the self-reported memory complaints in a 80 case-healthy-control study breast patients . Subjective memory complaints were assessed using the Prospective and Retrospective Memory Questionnaire . Results from the Paquet et al. study show that all participants (i.e., both patients and matched-controls) reported more PM than RM failures in daily-life (p<.001). Breast cancer patients reported more RM and PM failures than controls. However, this group effect was no longer statistically significant when controlling for depression and fatigue. These findings are consistent with the view that memory complaints are closely associated with depression and cancer-related fatigue, and more generally with psychopathological variables .As underlined by Paquet et al. subjective memory complaints should be investigated because they refer to some aspects of the cancer experience that could potentially be linked to quality of life. Thus, it is important to explore psychopathological basis such as depression, anxiety and fatigue while investigating self-reported memory failures in cancer patients. Despites the importance of PM, there have been, to our knowledge, only few studies evaluating PM complaints or PM functioning in patients diagnosed with an intracerebral tumor (such as Diffuse Low-Grade Glioma- DLGG- or glioblastome- GB) or extra-cerebral tumor (such as breast cancer - BC). Therefore, the investigators thought it would be useful, as a first step, to conduct a study to explore and to manage the PM and RM subjective complaints in cancer patients compared to another chronic disease, such as HIV. In fine, these data will help to identify a new target for psychological management focused on either psychopathological or neuropsychological rehabilitation

Evaluation of the Efficacy of a Physical Therapy-yoga-patient Educational Program for Breast Cancer Patients With Pain Due to Hormonal Therapy Treatment.

As much as 50% of patients treated with hormonotherapy (HT) for breast cancer (BC) suffer from osteoarticular pain during treatment. Secondary effects have become a real issue because of their consequences on the patients' quality of life, but also on treatment efficacy and survival when they induce dose reduction or premature withdrawal of treatment. Additional medicines (acupuncture, hypnosis, yoga) have become more and more popular these last years. 48 to 80% of patients with BC eventually choose them. A review comparing efficacy of various therapies to decrease osteoarticular pain concludes to a highest efficacy of anti-inflammatory treatments, paracetamol and yoga. It thus appears innovative to complete this care with a patient educational project (PEP) in postural yoga instructed by a trained physical therapist, which will enable patients to practice yoga postures at home by themselves. The investigators conducted a pilot study "SKYPE" with 24 algic patients treated with HT after BC, whose results are very promising. The investigators now propose in the continuity of the pilot study a multicenter randomized controlled study comparing the efficacy of SKYPE care on pain reduction, an educative care combining physical therapy and yoga, to a control group in patients treated with HT for a BC with osteoarticular and/or musculoskeletal pain. Furthermore, in order to examine whether yoga interventions may influence inflammation through their effects on the level of a wide range of pro- and anti-inflammatory cytokines (30), the investigators will Change in circulating cytokines' level between baseline level (T0) and post-treatment level (T2) in both groups will be analyzed and if so correlation will be established.
