Active clinical trials for "Breast Neoplasms"

Rationale The inter-individual pain experience immediately after surgery is considerable. In addition, a number of patients develop chronic post surgery pain (CPSP). Patients undergoing surgery for breast cancer are at risk of developing both acute post surgical pain as well as CPSP. Recently, in a group of patients with chronic back pain, it was demonstrated how subjectively reported pain is associated with specific electroencephalography (EEG) parameters, namely the N2 and P3 components of the pain event-related potential (ERP). It was concluded that ERP was associated with self-reported pain in daily life up to two weeks after the measurement. This resulted in the current hypothesis that EEG may be a predictor for postoperative pain. Study design Prospective cohort study. Within 2 weeks before surgery, 150 patients will undergo an EEG measurement with five 'vulnerability' tasks. The experiment will be repeated 6 months postoperatively. Study population: Female patients with breast cancer who will undergo breast surgery, between the ages of 18 to 65 years. Main study parameters/endpoints Primary outcome is postoperative pain, measured in a pain diary 4 days postoperatively. Secondary outcomes are development of chronic post surgery pain and quality of life. The main goal is to develop a comprehensive prediction model for acute and chronic postoperative pain after breast cancer surgery, based on the EEG results of the five vulnerability experiments.

The primary endpoint of this study is to show that this algorithm in high definition is superior to the classical algorithm in the diagnosis of lymph node metastases.

This study will examine specific biomarkers in primary invasive breast cancer and explore their correlation with patient outcome following standard neoadjuvant treatment.

This pilot clinical trial studies the use of the radiofrequency-guided localization in patients with abnormal breast tissue undergoing lumpectomy (a type of breast-sparing surgery). The radiofrequency identification localization system consists of an implantable radiofrequency identification tag and a hand-held radiofrequency reader to mark abnormal breast tissue before surgery and later surgically retrieve them. Radiofrequency-guided localization may make it easier to find and remove abnormal breast tissue during lumpectomy.

Breast cancer tissue is collected from women undergoing scheduled surgery for breast cancer. The tissue specimen are analyzed by MR spectroscopy. After MR, the intact tissue specimen can be analyzed by other methods, such as histopathology. The MR spectral profiles are compared to clinical findings such as the patients diagnosis, lymph node status and tumor size.

The purpose of this study is to identify which patients, receiving Faslodex within the approved label, benefit most from Faslodex treatment.

The purpose is to examine the original breast tumor material to see how much of a metabolizing enzyme (CYP3A4) is present in tumor material. The researchers want to see if this is in any way associated with how the patient responded to docetaxel. They also want to examine the genes in the tumor that are responsible for the production of CYP metabolizing enzymes, to see if they are normal or if they have polymorphisms, or change compared to 'normal' CYP metabolizing enzymes.

This phase III trial evaluates mammographic breast density in participants with hormone receptor-negative breast cancer enrolled on study A011502. High breast density has been shown to be a strong risk factor for developing breast cancer and decreasing breast density may decrease the risk for breast cancer. Participants treated with aspirin may show reduced breast density on a mammogram.

This study evaluates a new method of testing the lymph nodes in the armpit of patients with breast cancer for tumor involvement. All participants involved in this study will undergo an injection of a small amount of iron dissolved in liquid followed by an ultrasound of the axilla that will make previously invisible lymph nodes visible, allowing them to be sampled in an outpatient setting.

It is expected that patients who receive physical therapy before surgery will have greater range of motion (ROM), strength, function, satisfaction, and less swelling, pain, and anxiety following surgery compared to those in the control group.
