Filter by:RATIONALE: Studying samples of blood from patients with breast cancer in the laboratory may help doctors learn how well triptorelin given together with tamoxifen citrate or exemestane works in lowering estrogen levels. PURPOSE: This clinical trial is studying estrogen levels in premenopausal women who have undergone surgery for breast cancer and are receiving triptorelin and tamoxifen citrate or exemestane on clinical trial IBCSG-2402.
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.
The purpose of this research is to determine whether the drug, Bevacizumab (a monoclonal anti VEGF-A antibody), which is approved to treat patients with metastatic colon cancer induces hyperprolactinemia (increased prolactin secretion) in humans with intact pituitary function. Past studies have shown Bevacizumab to shrink tumor size and also increase prolactin levels. The mechanism of the hyperprolactinemia might be inhibition of pituitary portal vein transport, suggesting that Bevacizumab induces prolactin secretion from normal lactotrophs in the pituitary gland. Patients who have been treated with Bevacizumab for at least one month will be recruited to participate. The subjects who are being treated with Bevacizumab by Dr. Stephen Wolin (a sub-investigator) will be screened by him for study eligibility. Dr. Wolin will approach eligible patients with all the information and background of the study and see if they have an interest in being consented. If consented, there will be 2 blood draws for the research that is not part of their standard care in which 10 ml of blood is collected and prolactin, growth hormone, IGF-I, TSH, thyroxine, ACTH, and cortisol will be measured. One 5ml blood draw will occur before the administration of Bevacizumab and the second 5 ml blood draw will occur after the administration of the Bevacizumab. The investigators will then review the laboratory results. The blood tests are of the hormones of the pituitary gland to test pituitary function and see if there are any abnormalities with the secretions of the gland. Pituitary function abnormalities and hyperprolactinemia are diagnosed by looking at hormone levels in the blood and comparing them to the normal reference ranges. This study will only involve 10 subjects and will be conducted entirely at Cedars-Sinai Medical Center.
Older individuals account for one-third of new cancer cases and cancer-related deaths in the United States. Older individuals are more susceptible to having a decrease in physical and mental function following chemotherapy treatment. Geriatric assessment may provide a way to identify those older individuals at greatest risk of functional decline before treatment starts and during the period of treatment. Geriatric assessment includes a set of screening questions and tests designed to determine the physical and mental status of the individual at a point in time. Geriatric assessment also includes review of medications and other medical conditions the individual may have that may affect function. The investigators are conducting this study to determine if older individuals are able to complete the geriatric assessment using a computer format and how that corresponds to their treating physician's assessment of their functional status before and after starting a new chemotherapy treatment for colon, rectal, breast or lung cancer. The investigators will also evaluate the usefulness of a computerized form of geriatric assessment.
The primary aim of this study is to investigate the use of cone beam computed tomography (CBCT) for breast imaging in the diagnostic setting by providing a compelling body of evidence incorporating both non-contrast and contrast enhanced CBCT in the study protocol. The goal is to accumulate a body of evidence to provide data to incorporate CBCT into the diagnostic work-up of breast lesions.
The purpose of this research study is to find out more about distinguishing between cancerous and non-cancerous breast cancer cells at the edges of tumors. Using an FDA approved device to remove tumors, this device will be tested to see if it causes less tissue damage and therefore makes it easier to examine the tumor and make sure it is all excised. The tumors will be excised by standard surgical technique, and then the effects of the device on the removed tissues will be studied.
The purpose of this study is to evaluate the safety and efficacy of continued administration of paclitaxel given weekly in subjects considered to need to continue treatment after completion of the preceding "Phase II Clinical Study of Weekly Paclitaxel (BMS-181339) with Advanced Breast Cancer (Protocol No. CA139-371)"
RATIONALE: Vaccines made from gene-modified tumor cells may help the body build an effective immune response to kill tumor cells. Biological therapies, such as cyclophosphamide and trastuzumab, may increase the number of immune cells and make the immune response stronger. It is not yet known whether giving cyclophosphamide together with vaccine therapy is more effective with or without trastuzumab in treating patients with metastatic breast cancer. PURPOSE: This randomized phase II trial is studying the side effects of giving cyclophosphamide together with vaccine therapy and to see how well it works compared with giving cyclophosphamide and vaccine therapy together with trastuzumab in treating patients with metastatic breast cancer.
Being diagnosed and treated for cancer is usually associated with severe physical symptoms, impaired functional status, complex emotional, psychosocial and existential issues and substantial worries. Failure to help patients with their problems and worries can unnecessarily delay patients' recovery and rehabilitation, lead to chronic functional impairments, anxiety and depression and prolong patients' needs for health care and social services. The objectives of this interdisciplinary, international research project that includes collaboration with HELFO (The Norwegian Health Economy Administration), are to test and compare, in a randomized, controlled trial (RCT), the effects of (1) a practice-integrated online patient-provider communication (OPPC) service including access to asking questions to HELFO, (2) a multi-component Interactive Health Communication Application (IHCA) called WebChoice, and (3) usual care on: patient outcomes, health care and social services use and costs. Breast cancer patients undergoing treatment at three different hospitals in Norway will be randomized into two experimental and one control groups and will be followed with 5 repeated measures over one year. The proposed study will contribute to innovative methods and technologies that can radically improve patient-provider communication, care quality, and continuity of care. The two interventions tested in this study, the OPPC service with and without additional features of WebChoice, represent new forms of interactions and information sharing between patients and clinicians where patients can get seamless access to communication and information services from where and whenever they need it. This could significantly contribute to reducing unnecessary suffering, less fragmented health care, better efficiency, patient safety, patient satisfaction and have an impact on patients' health services utilization. The investigators' work addresses, therefore, important health policy goals with the potential for considerable societal gains.
The purpose of this study is to evaluate the disease free and overall survival of patients with breast carcinomas of small size, i.e., not greater than 2.0 cm and with clinically non palpable axillary lymph nodes, undergoing either conservative surgery and axillary dissection, or a similar treatment for the primary tumor and rapid analysis of the sentinel lymph node, the result of which determines axillary node dissection or its avoidance is based.
