Filter by:About 5% of breast cancers are metastatic at diagnosis and 20-30% of localized breast cancer become secondarily metastatic.Thanks to recent therapeutic advances, the median survival ranges between 12 months in 1970 and 18 to 24 months in 2000. However, patients suffer from many detrimental symptoms such as fatigue, pain related to treatment and metastasis. The physical, biological, psychological and clinical benefits of physical activity (PA) during treatment in patients with localized breast cancer have been widely demonstrated. Numerous studies investigated the effect of PA in non-metastatic breast cancer, but to our knowledge, only four interventional studies worldwide focused on the implementation of PA in patients with metastatic breast cancer.It seems appropriate to investigate the feasibility of PA intervention with patients with metastatic breast cancer to see if the observed effects in localized breast cancer are confirmed in metastatic breast cancer population. The ABLE study is an interventional cohort designed to assess the feasibility of a 6-month adapted physical activity intervention, performed under real life conditions in patients with metastatic breast cancer.
Breast cancer is the most prevalent cancer in women and annually accounts for 10% of new malignancies worldwide. In mainland China, approximately 169,000 females are diagnosed with breast cancer every year and constitute 12.25% of the breast cancer incidents worldwide. Additionally, 30% of early breast cancer turns metastatic, which is often incurable. Different from women with early breast cancer, women with metastatic breast cancer(MBC)must receive lifelong treatment, experience higher levels of emotional/physical distress, and feel frequent uncertainty about their health/possible death. They are also challenged to manage distressing adverse effects induced by different adjuvant treatments and experience heavy self-care demands during the transition period from being a patient to being a survivor. Thus, specific interventions to help women with metastatic breast cancer to recover from this traumatic event have been designed, and one of these is supportive-expressive group therapy(SEGT).SEGT has been found to achieve improvement in anxiety, depression, quality of life (QoL), family functioning, and satisfaction with treatment. However, the effect of SEGT on survival is inconsistent. Initial studies examining SEGT have reported a mean survival advantage of 18 months, however, these findings could not later be replicated.Yet, no study has reported a survival disadvantage for those given SEGT. In addition, we found no published articles on the application of SEGT among women with MBC in China. Owing to this dearth of previous research, it is unclear whether this therapy would exhibit positive effects within Chinese culture. Thus, we developed a "Be Resilient to Breast Cancer"(BRBC) program that is culturally tailored for Chinese females with MBC. This program was adapted from SEGT and is designed to increase resilience(defined as the capacity to bounce back after encountering a traumatic event) and QoL, decrease emotional and physical distress(allostatic load), and eventually prolong longevity. To better adapt to Chinese culture, we added education hosted by professional staff (e.g., clinical psychologists, dietician, Chinese medicine practitioner, etc.)in an effort to foster self-efficacy to combat symptoms (such as pain, fatigue, intrusive thoughts, etc.) through knowledge and technics (such as breath control, meditation, etc.),and to help patients gain a sense of control in their life. Second, trained mentors, who were breast cancer survivors themselves, were added to the group discussion to create non-hierarchical, reciprocal relationships through the sharing of experiences with those facing similar challenges. These mentors also provided women with first-hand information about treatment and offered suggestions to combat barriers to recovery.
Whole-body MRI including diffusion is a booming technique. Numerous studies have demonstrated its interest in metastatic cancers. Breast cancers, especially hormone-sensitive ones, are very osteophilic and bones are the most frequent metastatic site. Apart from morphological criteria (lesion size and RECIST criteria), MRI provides quantitative functional criteria (diffusion and ADC values). According to a recent study, whole body MRI is as good as PET/CT and more effective than bone scintigraphy for the diagnosis of bone metastases for cancers of breast and prostate with a high metastatic risk. Therefore, it seems appropriate to study the performance of whole body MRI in the pre-therapeutic assessment of breast cancer with a high risk for metastasis and the monitoring of metastatic breast cancer.
A phase II non randomized study evaluating the role of Androgen Receptors as Targets for therapy of pre-treated postmenopausal patients with ER/PgR-negative/AR-positive or ER and/or PgR-positive/AR-positive metastatic breast cancer. Study Design: Multicentric, Open-label not randomized trial. Description of Study Treatment: Daily oral administration of DHEA (Dehydroepiandrosterone) at the dosage of 100 mg/die in combination with a daily oral administration of anastrozole at dosage of 1 mg/die or letrozole at the dosage of 2.5 mg/die or exemestane at the dosage of 25 mg/die without interruption until discontinuation for progression of disease, unacceptable toxicity or discontinuation/withdrawal of participants from study treatment. Number of Subjects: 12 patients per group in the first step; if the number of responders is greater or equal to 2, recruitment will continue up to a total of 35 patients (per group). For the biological part, we will evaluate: 1. Correlation between AR expression and clinical and biological features (tumor size, nodal status, histotype, grading, proliferative index, ER, PgR, HER2) 2. Evaluation of AR expression on primitive and/or metastatic site in the two distinct populations of patients: ER/PgR- negative/ARpositive and ER-positive and/or PgR-positive/AR-positive 3. Evaluation of ER, PgR, HER2 expression on tumor cells of metastatic site (when it is possible) and comparison with the same features of primitive tumor. 4. CTCs analysis in term of molecular characteristics (gene expression and mutations) and functionality (vitality and tumorigenicity). 5. Prognostic and predictive role of Circulating Tumor Cells (CTC) evaluated at baseline before study treatment and at the moment of discontinuation of treatment.
Longer first line chemotherapy duration has recently been associated with a modest, but significant improvement in overall survival and a clinically meaningful and statistically significant improvement in progression-free survival, in metastatic breast cancer patients. Prolonging chemotherapy until disease progression, however, must be weighed against the detrimental effects of continuous chemotherapy delivery. The SNAP trial seeks to improve the tolerability of prolonged chemotherapy administration strategy by studying alternative treatment schedules, while preserving and possibly improving treatment efficacy in this disease setting. The availability of a new nanoparticle albumin-bound taxane, nab-Paclitaxel (Abraxane®), represents an opportunity to test this hypothesis. Nab-Paclitaxel has been developed in an attempt to reduce the toxicity associated with standard taxane administration (caused by the use of chemical solvents) while increasing antitumor efficacy. The SNAP randomized phase II trial evaluates three schedules of nab-Paclitaxel as prolonged chemotherapy administration strategy. Each of three arms will be compared to a historical reference of seven-month median progression-free survival (PFS) based on the most recent trial with docetaxel as control arm to determine whether any of the three arms are worthy of further investigation.
Diffuse large B-cell lymphomas (DLBCLs) represent 25 to 30% of adult non-Hodgkin lymphomas in western countries. DLBCLs are aggressive cancer but potentially curable with multi-agent chemotherapy. Whereas R-CHOP regimen has led to a marked improvement in survival, this disease remains a biologically heterogeneous entity. New therapeutic strategies are required including identification of patients' subgroups with different prognostic. This project is based on BMS_LyTrans and Goelams 075 clinical trial. A study of whole blood transcriptome in 75 DLBCL patients and in 87 controls showed that PD-L1 (CD274) gene was overexpressed in DLBCL patients. Preliminary results demonstrated that PD-L1 is detected in plasma of DLBCL patients with a significantly higher concentration than in controls. This protein was selected as a potential biomarker because of its established role in anti-tumoral immunity. Interaction between PD-L1 and its receptor PD-1 is known to inhibit activation of immune responses by inducing T-lymphocytes anergy and/or apoptosis. Moreover, a direct involvement of PD-L1 in the protection of cancer cells from lysis by activated T lymphocytes has been demonstrated. PD-L1 expression has been described in several solid tumours, including ovary cancer, breast cancer, colon cancer, renal cell carcinoma, non-small cell lung carcinoma and in hematological malignancies such as T-NHL, MM and Hodgkin's lymphoma. Furthermore the expression of PD-L1 by tumour cells is associated with poor prognosis. The blockade of PD-L1/PD-1 axis may represent a novel therapeutic approach in aggressive cancers. These first results incite to identify the cells releasing soluble PD-L1 and to investigate its role in the anti-tumoral immunity in DLBCL patients. The aim of this study is to identify cells producing soluble PD-L1 in DLBCL patients at diagnosis in comparison to others tumours known to express PD-L1 (metastatic breast cancer, Hodgkin's lymphoma, non-small cell lung cancer).
