Active clinical trials for "Breast Neoplasms"

Patients with breast cancer, who are treated with curative intent, have a combination of surgery (excision of the tumor) and a course of medical therapy (chemotherapy or endocrine treatment). Both treatments are associated with significant side effects. Chemotherapy is associated with nausea, vomiting, hair loss and bone marrow suppression, whereas endocrine therapy is associated with arthritis and menopausal symptoms. Patients taking either chemotherapy or endocrine treatment may experience a range of side effects. The range and severity of side effects experienced vary from patient to patient. Little or nothing is known about the reason for this difference. The aim of the investigators proposal is to develop a pretreatment test to identify patients who are likely to undergo moderate to severe side effects, and therefore help doctors and patients plan and optimize medical therapy. The pretreatment test will be based on identifying a metabolic profile which can differentiate those patients who are likely to have severe or moderate side effects from those with either no or mild side effects. To do this, the investigators will take urine and blood samples from patients before and after the administration of endocrine treatment or chemotherapy and generate metabolic profiles. Furthermore, the investigators aim to gain an understanding into why side effects experienced between different patients are so variable. To do this the investigators plan to perform cytokine analysis, targeted genetic analysis and pharmaokinetic analysis on blood sample collected from patients before and after treatment has commenced. Patients who have planned surgical excision of tumor and are recommended to receive medical therapy before or after surgery would be invited to join the study. Each patient will be required to make additional visits to the hospital to complete questionnaires regarding side effects experienced and for sample (urine and blood) collection. The investigators plan to recruit 168 patients.

This observational study will evaluate the routine clinical use and the safety and efficacy of capecitabine (Xeloda®) in participants with metastatic or advanced breast cancer. Eligible participants will be followed for up to 24 months.

To identify a panel of circulating miRNA markers which could help identify those breast cancer patients who are most likely to respond well to neoadjuvant and adjuvant chemotherapy, and indeed serve as an overall prognostic factor and stratify patients into risk categories which would further guide their management. Similarly, the investigators aim to identify a panel of circulating miRNA markers which could monitor patient's response to chemotherapy and hormonal therapies. Ideally a suitable panel of markers would show significant changes in expression level in good-responders whilst little or no change would be observed in miRNA expression in non-responders.

In a general radiation oncology practice, breast cancer typically comprises approximately 25% of the total patient caseload.1 Surgery is the primary modality of treatment. Radical mastectomy remained the mainstay of surgical therapy into the 1970s. Breast-conserving surgery followed by radiation therapy to the intact breast is an established standard of care for the majority of women with early stage invasive breast cancer. Recommended techniques for breast-conservation treatment are local excision of the primary tumor, preferably with clear margins, axillary lymph node dissection, and breast irradiation (45 to 50 Gy), usually with a boost (10 to 20 Gy, depending on tumor size and status of the surgical margins). The aim of this study is to compare the two boost regimen 10Gy/5#/1 week with 16Gy/8#/1.5 weeks in post lumpectomy patients of early stage breast cancer, following whole breast irradiation (WBI). The study will include 50 patients, (25 in each arm) of early stage post lumpectomy breast cancer patients. Each patient will be treated by WBI followed by tumor bed boost with either electron beam therapy or 3D CRT. The primary end point of the study will be assessment of acute and late radiation toxicities, cosmetic score analysis and local control between two schedules. Secondary end points will be recurrence-free survival.

Nearly three million living women have survived breast cancer. Physicians rely on clinical practice guidelines to make decisions on follow-up care. Among other things, the goal is to monitor for recurrence or side effects of treatment among survivors. It is unclear whether these guidelines represent the best approach for any given patient as they do not account for differences in disease or patient preferences and may not consider recent advances in imaging and treatment options. We seek to develop a new approach to surveillance following breast cancer treatment which will be more patient-centered and effective than the existing one-size-fits-all approach and will consider individual risk factors.

The purpose of this research is to better understand the relationship between employment and breast cancer. Research is being conducted to understand how workplace factors influence breast cancer patients' ability to adhere to recommended cancer treatment and effectively recover from cancer. Investigators hope to use the findings from the study to help working breast cancer survivors make informed decisions about treatment and employment in collaboration with their employers and healthcare providers.

This is a single-center, open-label, randomized, prospective study evaluating the safety and efficacy of HO/02/02 20µg topically applied daily for 15 minutes (with gauze) on treatment fields vs. standard of care (SoC), Aloe Vera treatment

The investigators want to know the role of Peripheral hematopoietic stem cell infusion in avoiding Drug Induced Liver Injury,and also try to research SNPs genotyping associated with Drug Induced Liver Injury.

MicroRNAs (MiRNAs) regulate the translation of RNAs and are implicated in cell proliferation and renewal both under physiologically normal as well as in malignant conditions. Dysregulation of specific miRNAs may be associated with either gaining oncogenic or loosing tumor suppressing functions. MiRNA dysregulation has been implicated in breast cancer tumorigenic (stem cell) and non-tumorigenic development. Therefore, miRNA profiling of treatment naïve and treatment-exposed breast tumors and sequential samples of blood/serum will allow for identification of miRNA markers of prognosis and as indicators and potential targets for personalized therapies. In this proposal, specimens from patients treated in the clinical breast cancer program on already existing protocols (IRB 05091 and 05015) will be characterized by Dr. Rossi's laboratory and collaborators, and the information gained will be applied to develop specific therapies.

This is a multicenter translational study to understand therapeutic resistance in patients undergoing standard chemotherapy for triple negative breast cancer. In the neoadjuvant setting, biopsy tissue samples from primary tumor will be collected and banked before the start of chemotherapy and after the completion of the treatment (post-chemotherapy and at the time of surgery). In the metastatic setting, tissue samples from metastatic lesions will be collected and banked before the start of chemotherapy and at the time of tumor progression. Additionally, blood samples will be drawn before treatment initiation (baseline) and at different time points during treatment. All samples will be stored in the Biological Resource Repository.
