Filter by:This study aims to compare the response of triple-negative breast cancer with deficient homologous recombination to intensified alkylating chemotherapy versus standard chemotherapy with dose dense AC and/or Docetaxel-Capecitabine.
A PET scan drop less than 20% in SUVs or below a certain absolute SUV value after the first course of neoadjuvant chemotherapy can predict pathological response, and could in the future lead to an early surgical intervention.
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, methotrexate, fluorouracil, and epirubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving cyclophosphamide together with methotrexate and fluorouracil before, after, or without epirubicin hydrochloride is more effective in treating patients with breast cancer that can be removed by surgery. PURPOSE: This randomized phase III trial is comparing three regimens of cyclophosphamide given together with methotrexate and fluorouracil, with or without epirubicin hydrochloride, to see how well it works in treating women who have undergone surgery for breast cancer. (Group III was closed to new patients as of 12/7/2009.)
The goal of this study is to increase our understanding of the adjuvant chemotherapy experience in older and younger adults by prospectively describing the longitudinal trajectory of functional status, comorbidity, and quality of life from before the initiation of chemotherapy to 6 months after the completion of treatment in older (65 and older) and younger (under 65) adults. In addition, we will determine the effect of pre-treatment physical functioning on physical recovery after the course of adjuvant chemotherapy. The secondary objective of this study is to explore if factors other than chronological age (functional status, co-morbid medical conditions, nutritional status, psychological state, cognitive function, and social support) predicts which patients are more likely to experience morbidity (defined as grade 3-5 toxicity, hospitalization, dose reduction or delay, or premature discontinuation of chemotherapy course) from adjuvant chemotherapy.
The purpose of this phase Ⅲ, multi-center, prospective, open-label, randomized,controlled study is to determine whether alternative non-cross-resistant adjuvant chemotherapy can increase distant disease free survival(DDFS) in operable patients non-response to primary chemotherapy.
The purpose of this research study is to find out if the combination of ABT-888 and temozolomide is safe and effective in treating patients with metastatic breast cancer. ABT-888 works by obstructing a DNA enzyme called poly (ADP-ribose) polymerase (PARP) which helps repair cancer cells damaged by chemotherapy. By blocking the PARP enzyme, the cancer cells are unable to repair themselves and as a result die. The other drug in this study is temozolomide. Temozolomide is designed to damage DNA in order to prevent cancer cells from reproducing. Because PARP inhibitors, such as ABT-888, prevent cancer cells from repairing their own DNA, they enhance the potential of chemotherapy therapy like temozolomide to induce cell death. The combination of ABT-888 and temozolomide has been used in a clinical trial for treatment of other cancers and information for this research study suggests that the combination may help to inhibit growth in breast cancer. ONLY THE EXPANSION COHORT BELOW IS RECRUITING: BRCA CARRIER EXPANSION COHORT: The purpose of the expansion cohort is to further evaluate the activity and safety of this combination in BRCA mutation carriers with metastatic breast cancer.
Breast cancer is the most common malignancy in the U.S. Targeted therapies such as tamoxifen have been revolutionary in reducing tumor recurrences and mortality in early breast cancer. Using this successful paradigm, there has been a continued search for other targeted biologic therapies directed at receptors with known potential for promoting tumor growth. The estrogen receptor (ER) and/or the HER signaling pathways are the dominant drivers of cell proliferation and survival in the majority of human breast cancers. Molecular targets of these pathways provide the most effective therapies in appropriately selected patients. However, de novo and acquired resistance remain major obstacles to successful treatment, and understanding the molecular pathways responsible for this resistance would enable the discovery of new strategies to overcome it. The superiority of multi-drug HER2-targeted therapy over single agent therapy has been demonstrated in the preclinical setting using mouse xenografts. Trastuzumab, pertuzumab, lapatinib, and gefitinib, represent a group of therapeutic agents that target the HER family by different molecular mechanisms. Used as single agents in the MCF7/HER2-18 xenograft model, these drugs restored or enhanced sensitivity to tamoxifen. However, tumor growth inhibition lasted only 2-3 months before resistance to treatments occurred. However, when gefitinib, a HER1 inhibitor, was added to the two-antibody (T+P) regimen to block signals from HER1 dimers, a complete disappearance of nearly all xenograft tumors was observed; moreover, there was evidence of complete tumor eradication in 50% of the mice. The combination of lapatinib + trastuzumab was also highly effective in eradication of tumor burden, with no evidence of re-growth after 200 days. These xenograft models demonstrate that multi-drug HER2-targeted therapy more effectively induces apoptosis and inhibits proliferation, thereby resulting in tumor regression. Furthermore, HER2 combination therapy appears to more effectively reduce levels of phosphorylated pAKT and MAPK, thus resulting in sustained tumor inhibition.
The purpose of this study is to develop a coordinated, standardized screening program for the early detection of breast cancer in high-risk women. This would include Breast Mammography and Magnetic Resonance Imaging (MRI) examination of your breasts. The University of Chicago Department of Radiology is performing research to develop better ways of imaging the breast. The investigators would like to be able to reliably identify abnormal tissue and determine whether abnormal areas contain cancer without surgical procedures (i.e., a biopsy which involves removing breast tissue with a needle or surgical instrument). Annual mammography has already been recommended for the patient based on family history or personal history of cancer. In young women, dense breasts sometimes make it difficult to find abnormal changes on breast cancer screening (mammograms). MRI, in combination with mammography, may increase the rate of detection of early cancers. In addition, MRI can provide better images of breast tissue. The investigators hope to prove that combining multiple screening measures including biomarkers improves the chances that, if you have a small cancer or pre-cancer, it will be found early. This study will also evaluate quality of life measures during breast cancer screening and compare breast MRI and mammogram in a high-risk population. The investigators will establish a database of clinical characteristics, blood biomarkers and interventions that will be saved for future analysis and aid in the development of more effective screening in high-risk women. This research will also help us develop tools for studies in the future.
The purpose of this study is to determine whether lactate-containing vaginal lubricant is effective in the treatment of young breast cancer survivors with sexual dysfunction.
The purpose of this study is to identify possible genetic polymorphisms that contribute to specific toxicities associated with capecitabine (hand-foot syndrome, diarrhea, and neutropenia). Additionally, this study will look at gene polymorphisms in patients experiencing the toxicities of interest, the frequency of polymorphisms and differences in drug metabolism.
