Active clinical trials for "Breast Neoplasms"

The investigators will use integrated PET/MR for the goals below: Use of PET-guided proton MRS (MR spectroscopy) and DCE MRI (dynamic contrast-enhanced MRI) for patients who will receive NAC (neoadjuvant chemotherapy) for breast cancer to monitor treatment response. Use of dynamic and static PET to monitor treatment response for NAC, and to investigate the correlation of PET results versus MRS, DCE MRI. Compare clinical staging by PET/MR and by clinical assessment. On pre-chemotherapy studies, to investigate the association of molecular marker status with the dynamic and static PET, MRS and DCE MRI parameters.

This was an open-labeled, multi-center, prospective, non-comparative study of the safety of Herceptin (trastuzumab) used as an adjuvant therapy in patients with early breast cancer who had previously received antracycline therapy before or after surgery.

This is a prospective examination of ribonucleic acid (RNA) extracted from tumor material of breast cancer patients treated with a neo-adjuvant therapy. The RNA will be analysed for expression of estrogen receptor (ER 1), progesterone receptor (PgR), HER2 and Ki-67 with MammaTyper™. According to the determined values for the individual parameters at least 4 subtypes can be distinguished to date Luminal A-type Luminal B-type HER2-type Triple-negative-type As non-clinical endpoint, the agreement of new subtyping with Immunohistochemical methods will be evaluated. As clinical objective, the 5 year Distant metastasis free survival (DMFS) and Overall survival (OS) will be reevaluated according to the new subtyping.

The objective of this surveillance is to collect information about 1) adverse drug reaction not expected from the LPD (unknown adverse drug reaction), 2) the incidence of adverse drug reactions in this surveillance, and 3)factors considered to affect the safety and/or efficacy of this drug.

RATIONALE: Gathering information over time about joint pain and stiffness from postmenopausal women with early-stage breast cancer who are receiving aromatase inhibitors may help doctors plan treatment and help patients live more comfortably. PURPOSE: This observational epidemiologic cohort is designed to study arthralgia, patient-reported outcomes, and medication adherence in postmenopausal women with early-stage breast cancer who are receiving aromatase inhibitors.

RATIONALE: Studying samples of urine from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at urine samples from women with newly diagnosed breast cancer.

This study aims to identify and quantify the factors associated with excess weight gain following treatment for breast cancer. It is believed that breast cancer patients gain more than 4% of their weight at diagnosis which is likely accompanied by an increase in body fat and waist circumference. It is further thought that this excess weight and increase in body fat and waist circumference are associated to tumour characteristics, chemotherapy, menopause status at diagnosis and the presence of genes related to obesity. It is also thought that women treated with chemotherapy have higher levels of glucose and insulin.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in peptides and proteins and identify biomarkers related to cancer. PURPOSE: This research study is looking at blood samples from patients with malignant melanoma, metastatic breast cancer, advanced lung cancer, pancreatic cancer, or colorectal cancer.

RATIONALE: Collecting and storing information from patients with cancer to study in the future may help doctors learn more about cancer. PURPOSE: This study is collecting information from patients enrolled in the Breast Specialized Program of Research Excellence.

Background: Identification of new biomarkers with potential predictive and prognostic role has contributed unequivocally to breast cancer treatment. Although traditionally endocrine therapy is based on hormonal receptors status (estrogen - ER and progesterone- PR), some patients become hormone resistant. In order to identify a possible profile associated to hormonal resistance, some biomarkers have been assessed after short period primary hormone therapy (HT). Objectives: To compare the expression of Ki-67, Bcl2, Bax, Bak, ER and e PR in postmenopausal women with ER positive invasive ductal carcinomas (IDC), prior and after tamoxifen and anastrozole in short term hormone therapy.
