Filter by: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.
The purpose of this study is to assess the pharmacokinetics of bosutinib and the safety and tolerability of bosutinib in healthy subjects and subjects with liver disease.
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.
Study to compare the prototype tomosynthesis mammography system to the tomosynthesis system slated for commercial release.
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
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.
The primary objective of this study is to compare image processing software to support a new image processing software application for a full-field digital mammography (FFDM) system.
Women with breast cancer undergo treatments that decrease the chance of recurrence of cancer, but are associated with several side effects, including declines in memory and attention and other thinking abilities. The causes of these declines are not known. However, we know that (i) people with cancer may have high levels of molecules in the blood (cytokines) that reflect inflammation; (ii) injection of cytokines into animals, and their use to treat some human diseases, can lead to decreased memory and attention; and (iii) in some advanced cancers cytokines predict disease outcome. This longitudinal study evaluates the relation of cytokines to decreased thinking abilities and to disease outcome over time. Results of this study may help develop interventions to prevent or minimize cognitive decline and identify women who are at high risk for recurrence, and such information could be used in treatment decisions and in the development of new treatment options.
RATIONALE: Abiraterone acetate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I/II trial is studying the side effects and best dose of abiraterone acetate and to see how well it works in treating postmenopausal women with advanced or metastatic breast cancer.
