Filter by:There are three main objectives, centering on those patients targeted for surveillance imaging. The first objective is to compare image quality and specificity of breast tomosynthesis and conventional 2D mammography in a BIRADS 3 diagnostic population. The second objective is to compare image quality and ability to determine post-surgical and post-radiation changes from recurrence in a post-cancer subset of a BIRADS 3 population having undergone conservation therapy (lumpectomy with or without radiation. The final objective is to compare image quality and the ability to determine chemoresponsiveness in a post-cancer subset of a BIRADS 3 population, who are undergoing neoadjuvant chemotherapy.
Aromatase Inhibitors (AI) are effective for secondary prevention of breast cancer and may soon replace tamoxifen as first-line therapy in the treatment of hormone-sensitive breast cancer. However, because these medications produce a marked reduction in serum estrogen levels, this is likely to result in an increased rate of bone loss and risk of developing osteoporosis and fractures in postmenopausal women treated with these agents. Indeed, substantial bone loss has been reported in several large clinical trials of AIs. Osteoporosis drugs are available that could prevent this loss, but they have frequent side effects and are expensive. Thus, treating all women receiving AIs might not be the most appropriate and cost-effective approach. A better approach might be to select women at highest risk of bone loss and only treat them with antiresorptive agents. The proposed pilot study will evaluate women who receive anastrozole or letrozole therapy, are receiving adequate amounts of calcium and vitamin D and have baseline normal or moderately low bone mass in order to determine if early changes in bone turnover markers correlate with bone loss at one year. If data from this pilot protocol support our hypothesis, then we would propose a larger trial to confirm it. The ultimate aim is to predict which women are at higher risk of bone loss and therefore treat them earlier with bone-sparing agents, while those with lower risk could be monitored on conservative therapy.
The investigators major aim is to determine whether there is a difference in the retention of zoledronic acid in multiple myeloma patients, compared to patients with breast cancer metastasis to bone. In addition the investigators wish to analyze if the retention of zoledronic acid is correlated to the extent of bone resorption/formation, and if there is a tendency to changes in retention with sequential treatment.
OBJECTIVE: To find out the effectiveness of early application of physical therapy in the prevention of lymphedema after breast surgery and lymphadenectomy. DESIGN: Randomized, controlled and single blinded clinical trial. Three years duration. Patients will be randomly assigned to one of these groups: Experimental group: Early physical therapy + training in means of prevention; Control group: just training in means of prevention. In both groups several physical therapy assessments will be undertaken: 1st before surgery; 2nd immediately after surgery; 3rd after completing intervention; 4th, 5th and 6th after 3, 6, 12 and 24 months. SUBJECTS: Women with breast cancer treated with breast surgery including lymphadenectomy in Principe de Asturias Hospital, provided that there is no contraindication for physical therapy, and after reading, understanding and freely signing an informed consent form. SAMPLE SIZE: A total of 116 subjects will be included in the study (58 subjects in each group), assuming a 15% of drop-outs and at least 20% reduction, with a statistical power of 60%. DATA ANALYSIS: To find out the effectiveness of intervention we will compare the rate of lymphedema in both groups by means of a logistic regression analysis, in which the main factor is the intervention group. Other factors aimed to control the effect of the intervention will also be included. In order to compare the rate of appearance of lymphedema in both groups, a survival analysis will also be included.
A study to evaluate the response of growth factor signatures (GFS) to a single dose of dalotuzumab in participants with triple negative (TN) or estrogen receptor (ER)-positive luminal B breast cancer. The primary hypothesis is that dalotuzumab will induce a decrease in the GFS in at least 40% of participants.
Hormone receptor positive breast cancer is the most common type of breast cancer, comprising 70-80% of all breast cancers. Endocrine therapy is the main type of initial treatment for patients with your type of breast cancer. Endocrine therapy is treatment that tries to remove, or block certain hormones from binding to the cancer cells and thus slow or stop the growth of cancer. Although most patients with your type of breast cancer respond initially to endocrine therapies, it can lose its effectiveness. New therapies for this type of cancer are needed.
Aim: This study aims at evaluating the performances of an intraoperative gamma camera (field of view 10X10 cm), named CarolIReS, to detect axillary drainage and to assess the removal of sentinel lymph nodes (SLN) in breast surgery. Patients and Methods: SLN biopsy will be performed on 110 patients and the CarolIReS camera will be used preoperatively to localize SLNs. During surgery, individual removal of SLNs will be performed using a gamma probe named CarolIReS and their activity will be measured with a gamma ray counter. At the end of surgery, the CarolIReS camera will be used again to check the quality of surgery which will be followed by a surgical excision in case of remaining SLNs. Objectives: The main objective of this study is to evaluate the performances of the CarolIReS camera in assessing the axillary drainage of breast tumors and the surgical removal of SLNs. In addition, the possible correlation between the activity, the size, and the metastatic involvement of the SLNs will also be studied.Study hypothesis: Intraoperative cameras could be used to improve the efficiency of the SLN procedure
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This study is looking at genetic susceptibility to cancer and interactions between genes and the environment in patients with breast cancer.
The study objective is to assess the performance of the MammoDetector Pro to correctly mark biopsy-proven breast cancers imaged on the Siemens Mammomat Novation FFDM system compared to conventional film-screen mammography.
The purpose of this research project is to study the effect of a research (investigational) drug, MK-0752 combined with either tamoxifen or letrozole on breast cancer cells. Tamoxifen and letrozole are standard hormone treatments used to treat breast cancers that are positive for the estrogen receptor. However, over time the breast cancer cells can become resistant to tamoxifen and letrozole. MK-0752 is in a class of drugs called gamma secretase inhibitors. Gamma secretase inhibitors may play a role in reversing the resistance to drugs such as tamoxifen and letrozole.
