Active clinical trials for "Breast Neoplasms"

This study aims to constitute a most complete biological collection for patients treated for localized or metastatic breast cancer (in different cohorts depending on the type of systemic treatment received), in order to describe the basal immune response of patients treated for a breast cancer according to the stage of the disease, but above all to study how the different systemic treatments used in the management of breast cancer modulate this immune response.

The study will test the hypothesis that inflammatory markers measured at 24 hours after breast cancer surgery will be lower in patients receiving PECS II and PIFB blocks, supplemented with dexmetomidine compared to standard care group.

The purpose of this study is to evaluate financial toxicity, or financial harm, in breast cancer patients. The study will follow patients throughout their cancer treatment. The study investigators will measure if patients are experiencing financial toxicity and if it changes throughout treatment, and whether it's associated with different cancers, treatments, or demographics. Also, the study investigators will measure if financial toxicity impacts other areas of life (e.g., well-being, satisfaction). Finally, patients will be asked to estimate how much money they expect to spend on out-of-pocket expenses during their treatment and how their finances and employment status have changed since their cancer diagnosis.

The purpose of this clinical research is to evaluate the accuracy of a multi-parametric model based on magnetic resonance imaging (MRI) in predicting pathological complete response (pCR) after the first cycle of neoadjuvant chemotherapy (NAC) given to patients with locally advanced breast cancer, thus allowing early chemotherapy regimen modification to increase number of patients achieving pCR or save patients from toxic effects of ineffective chemotherapy.

This study investigates the clinical course of CDK4/6 inhibitor treated patients in the real-world setting among patients with breast cancer. CDK4/6 inhibitors may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Studying samples of blood, tissue, ascites or pleural effusions, and fresh body fluids or fresh biopsy, from patients with breast cancer that has spread to the other places in the body (metastatic) may help doctors learn more about cancer and the development of drug resistance in patients, and predict how well patients will respond to treatment.

A multi-center, prospective, cohort study to evaluate the efficiency of breast cancer screening based on Automated Breast Ultrasound (AB US) with remote reading mode.

This is an observational study of the occurrence of cardiac toxicity in patients with breast cancer,lymphoma or leukemia receiving chemotherapy including an anthracycline. Patients will be identified at the oncology clinic and will be included in the study if all eligible criteria are met. The study will involve retrospective and prospective evaluations. Safety will be assessed through reporting of serious adverse events (SAEs) related to study procedures.

The present project aims at identifying robust candidates for drug resistance in BC patients eligible for NAC. Its originality lies upon the combination of three different and complementary prospective approaches: from the molecular analyses of biopsies sampled before and after NAC, from in vitro BC Patient-Derived Organoids (PDO) mimicking patient's response to NAC, and from Circulating Tumor Cells (CTCs) isolated before/during/after NAC.

This randomized phase III trial studies metformin hydrochloride to see how well it works compared to placebo in preventing breast cancer in patients with atypical hyperplasia or in situ breast cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of metformin hydrochloride may prevent breast cancer.

The primary goals of this trial will be to determine the safety and immune activity of HER-2 pulsed DC1 vaccine in patients with high risk HER-2pos breast cancer with residual disease post neoadjuvant therapy. Investigators will also explore the possibility of determining whether circulating tumor cells can be used as surrogate to assess response to vaccination.
