Active clinical trials for "Breast Neoplasms"

This study assesses changes to the immune cells following hypofractionated radiation-induced DNA damage in breast cancer patients. Radiation therapy may cause immune cells to enter tumors and target cancer cells. The goal of this study is to measure the change in the level of immune cells in the tumor before and after radiation therapy.

Breast cancer is the most common malignancy in women in our country (2013 cancer registry report, Health Promotion Administration). MRI is a more accurate imaging modality for breast lesion diagnosis, monitoring of treatment response, and local staging than compared with mammography and ultrasound. ¹⁸ F-FDG PET was reported to be used for breast cancer diagnosis, staging, and prediction of treatment response as well. We usually interpret the aforementioned imaging modalities by qualitative methods for decision-making. Radiomics is a process involving the conversion of images to quantitative data for subsequent data mining to improve decisional making for patient care, to adjust the patient management, that is so-called precision medicine. Our study is to use semantic and agnostic features of radiomics by hybrid PET/MR for 1. The pre-operative breast cancer patients (without neoadjuvant chemotherapy before operation). 2. The patients will receive neoadjuvant chemotherapy (NAC). The study intends to investigate the association of PET/MR radiomics data with the probability of metastasis or risk of recurrences and survival. We will also investigate if the BD and BPE (measured on MRI) are associated with molecular subtypes, histologic grade and clinical outcome, risk of metastases, and long-term survival of breast cancer patients for the study participants.

Database of Institut Paoli-Calmettes patients diagnosed with breast cancer

In order to accelerate border crossing between basic research and clinical research in breast cancer, it is necessary to easily use clinical and biological data. That is the reason why it is very important to create a clinical, biological and pathologic beast cancer database, mainly prospective but also retrospective. All data are from patients treated in Toulouse Centre. The scientific community will easily have access to clinical and biological informations through a centralized, structured database , leading to optimize patients with breast cancer treatment.

This is a non-treatment study. It will not involve the use of any investigational drug or device. Potential participants will be enrolled through direct contact with collaborating clinical sites when the patient's annual 3D mammogram report yields a BIRADS rating of 4-5. The clinical Investigators or a member of their staff will conduct consent discussion once a suspicious mammogram report is identified or if a patient is referred for imaging of a suspicious area in the breast. After consenting the participant will be asked to donate a blood sample, a saliva sample, medical records pertaining to the suspicious mammogram report and a medical history questionnaire. The participants will be followed after one year to capture progression or resolution of their suspicious mammogram report. After a biopsy confirms the diagnosis of cancer or benign lesion, a recut sample of the tissue may be requested for research.

The risk of diagnosis of cancer increases with age, especially breast cancer in elderly women. Elderly population is heterogeneous, regarding physiological reserves, comorbidities, disability and geriatric conditions. Comprehensive geriatric assessment (CGA) is a multidimensional approach to determine geriatric profile, in helping the therapeutic strategy. In-patients with diagnosis of cancer are screened with the FOG (oncology geriatric filter), to identify vulnerable subjects who may benefit from CGA. This scale of ten questions includes geriatric domains such as functional status, nutrition, mood, cognitive abilities and comorbidities. In elderly patients with breast cancer considered as fit (FOG=0), CGA is not necessary before adjuvant treatment. In vulnerable patients (FOG ≤ 1 and < 3), CGA is held in routine to discuss the adjuvant therapy feasibility. Patients with FOG ≥ 4 underwent CGA if palliative care is considered. Patients in the intermediate group (FOG 1-3) are randomized to determine time of CGA, before or after surgery. The aims of this study are to assess the outcomes regarding the time of CGA, in elderly female patients with breast cancer management, and to define the optimal place of CGA in care pathway.

We hypothesize that variations in anatomic location of the arm lymphatic drainage system put the arm lymphatics at risk for disruption during a SLNB and / or ALND. Therefore, mapping the drainage of the arm during the procedure would decrease the likelihood of inadvertent disruption of the lymphatics and the subsequent development of lymphedema. A combination of radioactivity and blue dye will be used.

Establishment of a tumor bank, consisting of tissue samples of tumor patients (benign and malign tumors) and healthy people as controls. The tissue samples will be collected systematically together with the corresponding clinical data. The biological samples, the clinical date together with prospective experimental date constitute the entity of the tissue tumor bank. This tumor bank for tissue samples, together with our tumorbank for blood samples (NCT01763125) combined constitute the entity "Tumorbank".

The purpose of this study is to test whether patients undergoing a breast MRI (magnetic resonance imaging) before breast surgery will have better results after the surgery. Breast tumors are routinely evaluated using mammograms and ultrasound before surgery. This study would like to find out if using MRI in addition to mammography before surgery improves our ability to evaluate tumors and decide what kind of surgery is best for the patient.

This project is aimed at investigating the relative diagnostic and synergy of four state of the art breast imaging techniques (magnetic resonance imaging (MRI), full-field digital mammography (DMAM), ultrasound, and positron emission tomography (PET)) with respect to determining the extent of breast cancer.
