Active clinical trials for "Breast Neoplasms"

This is a prospective and observational study, aiming to determine the detection rate and change of CtDNA in blood samples of cancer patients before, during and after neoadjuvant treatment. Determine the rate of ctDNA positivity at the time before treatment, Determine the rate of ctDNA positivity at the time during treatment, Determine the rate of ctDNA positivity at the time after neoadjuvant therapy, whether there is a change in ctDNA expression of the study population during treatment. And aiming to investigate the relationship between ctDNA expression and MRI imaging with pCR response in neo-adjuvant therapy: Correlation between ctDNA detection and pCR response. Determine the percentage of Positive Prediction Value - PPV, Negative Prediction Value - NPV of ctDNA, Correlation between MRI imaging and pCR response. Determination of PPV, NPV of MRI Combination of ctDNA detection and MRI imaging in the prognosis of pCR. Determination of PPV, NPV ratio of ctDNA combined with MRI.

This study aim to investigate the breast reconstruction outcome after mastectomy with or without radiation therapy from the patient's point of view.

This research study is evaluating whether contrast enhanced mammography can be used as an alternative to breast Magnetic Resonance Imaging (MRI) for cancer screening

Establishment of a tumor bank, consisting of blood samples of tumor patients and healthy people as controls. The blood 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 tumor bank.

The Breast Cancer Program Longitudinal Repository (BCPLR) is being established to fulfill the research mission of the Breast Cancer Program at Johns Hopkins and to serve investigators affiliated with it - to develop a repository of specimens with corresponding characteristics from patients seen in the breast care and cancer clinics.

This pilot trial studies whether a procedure called lymphovenous bypass would prevent lymphedema (arm swelling) in patients with inflammatory breast cancer or non-inflammatory breast cancer that has spread to nearby tissues or lymph nodes. The lymphovenous bypass procedure creates a path for lymphatic fluid to flow away from the arms. It is usually done after a diagnosis of lymphedema. In this study, giving lymphovenous bypass before underarm lymph node surgery may help prevent lymphedema from forming.

This trial collects clinical information and tissue and blood samples from patients with breast cancer that has come back or is stage IV. Collecting clinical information and biospecimen samples to create a registry may help doctors better understand the mechanism of tumor spread and determine why people respond differently to specific cancer treatments.

The FLEX Registry will be implemented to operate as a large-scale, population based, prospective registry. All patients with stage I to III breast cancer who receive MammaPrint® and BluePrint testing on a primary breast tumor are eligible for entry into the FLEX Registry, which is intended to enable additional study arms at low incremental effort and cost. FLEX Registry will utilize an adaptive design, where additional targeted substudies and arms can be added after the initial study is opened.

The goal of the project is to identify a molecular signature of tumor stroma from "normal" adjacent breast tissue obtained prospectively at the time of breast conserving surgery before and after receiving intraoperative radiation therapy (IORT) in subjects that have luminal A and triple negative breast cancer. IORT is considered as being standard of care.

Prospective, single-center study in women who have recently had an abnormal mammogram followed by a breast biopsy or women who have recently had a normal screening mammogram. We are no longer enrolling women who had normal Screening mammograms.
