Filter by:Patients who are diagnosed with breast cancer will have surgery to remove the tumour. Where this is a local excision not mastectomy, the tissue removed is sent for x-ray imaging to assess that the abnormality has been removed and give an estimation of the distance from lesion to specimen edge. This allows the surgeon to decide whether to remove more tissue or not at the time. This study is designed to compare whether more accurate information about lesion to margin measurement can be obtained using 3 dimensional tomosynthesis imaging compared to 2 dimensional conventional digital imaging which is the type of imaging currently used. This has the potential to prevent some patients requiring a second operation to remove more tissue if the margins of the specimen are still involved with tumour. The study involves x-raying the specimen under both conditions when it arrives from theatre. Only the 2D image will be reviewed at the time as is current practice. The 3D image will be reviewed later and the measurements for lesion to specimen margin compared. The lesion to margin measurement as recorded by the pathologist will be taken as the 'gold standard' and the imaging measurements will also be compared to that. In theory, the use of 3D tomosynthesis should allow more accurate lesion to margin measurement because 3D can provide better visualisation of the lesion edges by removing the effect of superimposed tissue. The hypothesis states that the use of 3 dimensional tomosynthesis imaging should provide better lesion visualisation compared to 2 dimensional conventional digital imaging thus allowing more accurate lesion to margin measurement.
Adjuvant chemotherapy is frequently proposed to patients presenting early breast cancer, in case of high risk of recurrence (large tumors, node involvement, high grade…). Due to its toxicity toward veins, chemotherapy must be administered through a central venous device. Today, one can use either an implanted port or a PICC line (Peripherally Inserted Central Catheter). A PICC line is easier to implant and to explant, but has to be flushed every week and may impact daily life (no swimming, some clothes may not fit). On the other hand, a port is subcutaneous and lets patients lead a normal life, but its implant and explant require a cutaneous incision with possible complications (bleeding, pain, infection). For both venous devices, complications such as thrombosis or infection may happen. Published data comparing the two devices are heterogeneous and do not often distinguish patients treated for different diseases at various stages. Empirically in daily practice, for long term use (>6 months) a port is usually preferred, whereas for short-term treatments (<6 weeks) a PICC line is used. In the case of Her2 negative early breast cancer, adjuvant chemotherapy usually lasts 4 to 5 months. There is no scientific evidence for preferring one device to the other for these patients. The aim of this study is to prospectively compare the patients' satisfaction and tolerance of each of the two devices.
This is an open-labeled, exploratory, single center study. Patients with a big primary breast cancer (≥ 3 cm) or metastatic first line, routinely have their HER2-expression determined by biopsy. Patients having a HER2-positive tumor will be recruited to the study. A [18F]FDG PET/ceCT scan is performed for the measurement of uptake in the tumour and diagnosis of possible metastases. Each subject will receive a single injection of the investigational product [68Ga]ABY-025, followed by measurement of uptake in the tumour or metastases and in normal organs. The investigations will be repeated after HER2 directed therapy.
The aim of this study are to to evaluate the knowledge and understanding on tamoxifen theraphy for breast cancer patients and examine the decision conflict scale and satisfaction with decision scale while making decision to take tamoxifen.
The aim of this study is to assess the impact of a decision aid leaflet on the participation of women invited to participate in the French national breast cancer screening program.
An imaging method has been developed that uses near infrared light as an adjunct to ultrasound for better diagnosis and for monitoring tumor response. This study will use a new, non-invasive way to evaluate breast lumps using a low power light source & ultrasound to see if breast lumps are benign or cancerous. This study will also evaluate if this new technique might be useful in assessing response to chemotherapy.
The purpose of this study is to evaluate the efficacy of enzalutamide with trastuzumab in patients with HER2+ AR+ metastatic or locally advanced breast cancer.
The purpose of this study is to evaluate the efficacy and cost-effectiveness of an internet-based cognitive behavioural therapy program in alleviating problems with intimacy and sexuality in women treated for breast cancer.
The study is a prospective multi-center randomized control clinical trial which is sponsored by the researchers. The purpose of this study is to determine the effectiveness of adjuvant endocrine therapy for operable ER-beta positive, ER-alpha/PR negative, Her-2 negative breast cancer(triple negative breast cancer, TNBC) patients. The ER-beta positive TNBC patients who had undergone modified radical mastectomy or breast-conserving surgery were randomly (1:1) enrolled to receive toremifene (60 mg per day for premenopausal and perimenopausal patients) /anastrozole(1mg per day for postmenopausal patients) or observation within 4 weeks after adjuvant chemotherapy and/or radiation therapy if necessary.The follow-up time will be at least five years. The disease free survival(DFS) and overall survival(OS) between endocrine group and observation group will be compared to evaluate the effectiveness.
The previous reported phase I study allows us to prospectively define the optimal total dose in different metastatic locations (88). However, several questions are still unanswered such as the adequate timing of the stereotactic body radiation therapy (SBRT) in oligometastatic disease. Indeed, there are two different oligometastatic states: "de novo", i.e. occurring at first metastatic presentation without any previous systemic therapy; and "secondary", defined as residual disease after systemic treatment. The investigators wish to prospectively study the role of metastases SBRT with curative intent in de novo oligometastatic disease. This clinical trial would be the first randomized study studying SBRT at onset of the metastatic disease. If this trial shows a PFS improvement, it will definitively change the standard of treatment and it will highlight SBRT as a key treatment of metastatic disease. It will confirm the oligometastasis hypothesis as well as the Simon Norton hypothesis (92).
