The current observational study aims at analysing current semiology on breast cancer patients aiming at noting indicators and signs with significant relationship with the disease outcomes. To reach the primary objective, of identifying most prominent indicators and signs, a study group of at least 100 female patients with breast cancer diagnosis will be recruited to participate voluntarily. The study group will include at least 20 patients with metastatic cancer and 30 patients with indication to adjuvant chemotherapy. Their physical activity habits and lifestyle will be noted. The observational study will consist in the periodic registration of the overall physical and psychological condition. The variables and tests below will be measured and registered, periodically: - periodical assessment of the quality of life - periodical assessment of the fitness status of the subjects - assessment of changes in bone density/progression of osteoporosis - assessment of changes in cognitive function - assessment of sleep disorders The collected results will be statistically analysed, in order to: - Identify variables that are statistically significantly different from expected values - quantify statistically significant differences, whenever possible The results will be used to better describe the breast cancer population
Docosahexaenoic acid (DHA) is an omega-3 long chain polyunsaturated fatty acid (n-3 LCPUFA). N-3 LCPUFA are essential fatty acids in the diet. The majority of n-3 LCPUFA in the diet is alpha-linolenic acid (ALA). While DHA can be synthesized from ALA and other n-3 LCPUFA in the body, endogenous synthesis is low. Consequently, the only way to significantly increase levels of DHA in tissues is by directly consuming this fatty acid. Common sources of DHA are fatty fish, fish oil and omega-3 supplements and fortified foods. DHA is readily incorporated into membrane phospholipids and induces changes in the properties of the cell membrane including altered fluidity; permeability and membrane transport as well as activity of membrane bound receptors and enzymes. It is well established that changes in membrane DHA has multiple effects in the body, including modulation of neurological, immune, and cardiovascular functions. In breast cancer, DHA increases sensitivity of breast cancer cells to different chemotherapeutic agents, and in animal models of breast cancer, dietary DHA decreases tumour growth. The investigator's preclinical studies demonstrate that DHA increases efficacy of both doxorubicin and docetaxel, two agents commonly used in the adjuvant setting for breast cancer treatment. Furthermore, DHA mitigates chemotherapy induced weight loss in mice, and reduces paclitaxel toxicities in breast cancer patients, strongly indicating that DHA protects against toxicity in normal tissues. Directly relevant to this study, increased DHA in breast adipose tissue correlates with improved response to chemotherapy, and increased dietary intake of n-3 LCPUFA, including DHA, results in increased DHA incorporation in breast adipose tissue. Lastly, in advanced metastatic breast cancer, DHA supplementation correlated with improved outcomes in a subset of patients. Consequently, the Investigators hypothesize that the therapeutic index (efficacy: toxicity ratio) will be improved with the addition of DHA. In this clinical trial, the Investigators will explore the benefit of DHA supplementation in combination with neoadjuvant chemotherapy in patients with early breast cancer. RESEARCH QUESTION & OBJECTIVES: The Investigators propose to evaluate incorporation of DHA in women with breast cancer in treatment naïve patients in combination with chemotherapy, and assess potential benefit of DHA supplementation in breast cancer patients, using change in Ki67 labeling index (marker of proliferation) as a marker of efficacy. This study will further investigate the relationship between DHA in plasma phospholipids (as a potential biomarker of tumour incorporation) and effect on systemic immune function. METHODS: Patients directed to receive chemotherapy will receive capsules, each containing a minimum of 400 mg of DHA in the form of DHA enriched triglyceride oil or placebo (corn/soy oil blend) to be taken orally (11 capsules/day, throughout day as preferred by participant) for a total of 5 g DHA or placebo, for 12-18 weeks (84-126 days) beginning at the start of the first cycle of chemotherapy, and continued throughout 4-6 cycles of chemotherapy (3 weeks/ cycle). DHA will be discontinued 21 days after the last administration of cytotoxic chemotherapy. Tumour biopsies at baseline and post surgical removal will be assessed for Ki67 status as well as for markers of apoptosis and stem cell presence (by immunohistochemistry). Blood samples taken at baseline prior to each round of chemotherapy will be assessed for immune markers and plasma phospholipid content.
Breast loss causes negative influence on women physically, psychologically and socially. Breast prosthesis can improve patient's figure externally, increase self-confidence, thus improving quality of life. The objective was to understand the knowledge regarding breast prostheses in breast cancer patients, evaluate the quality of life of patients wearing different types of breast prostheses and to compare the physical and psychological effects of different temperature-controlled breast prostheses on patients. The investigators designed a randomized control study in one cancer center in Shanghai. In the first 6 weeks of the study, self-adhesive breast prostheses and conventional breast prostheses were used in the intervention and control group, respectively. In the later 6 weeks, the breast prostheses used were switched into another kind. Several dimensional parameters were examined by different questionnaires at the end of both 6th and 12th week including scars and skin, survey of breast prosthesis knowledge, survey assessing the comfort and practicality of breast prostheses, quality of life instruments for cancer patients and body image scale. The investigators expected that women would be satisfied with the temperature-controlled breast prosthesis and were more willing to choose self-adhesive breast prostheses.
The main objective of this trial is to investigate the efficacy and safety of hypofractionated radiotherapy of 3 or 4 weeks by comparing with conventional radiotherapy of 5 or 6 weeks using intensity-modulated radiation therapy (IMRT) in breast cancer patients with an indication for regional nodal irradiation (RNI) following mastectomy or breast conserving surgery. Patients will be randomized to hypofractionated radiotherapy or conventional radiotherapy delivered to chest wall or whole breast and regional lymph regions (including supraclavicular and internal mammary lymph nodes). Eligible breast cancer patients will be followed for at least 5 years to evaluate the difference in 5-year locoregional recurrence, over survival, distant metastasis, toxicity and life quality between two groups.
The study aim is to perform a comprehensive and integrated characterization of mechanisms of primary and acquired resistance to Kadcyla in a prospective cohort of progressive/recurrent HER2-positive breast cancer patients.
This mechanistic study will be the first study to assess the efficacy of [18F]GE-226 to target HER2 expression in patients with metastatic breast cancer. The study will establish the pharmacokinetics of [18F]GE-226 and the optimum time-point for performing static scans in this patient population.
INTRODUCTION: Breast cancer is one of the pathologies affecting women worldwide, with a high mortality rate of 14,206 per 100,000 women per year. However, Pilates was used as a therapeutic treatment for women who underwent a modified radical mastectomy, being associated with the alterations when in the postoperative sequels. OBJECTIVE: to evaluate the Pilates Method in the functionality of women submitted to modified radical mastectomy. METHOD: This is a quantitative clinical trial, in the form of women included in the project, to undergo a physical therapy rehabilitation program through the Pilates Method for 2 months, where they were evaluated before and after the procedure for measurement and comparison obtained. CONCLUSION: In this way, the pilates method is presented as an instrument used for the rehabilitation of mastectomized women.
This multi-site study is being conducted to examine dietary and activity patterns, body composition, blood and quality of life in breast cancer patients. The study will recruit 176 women with MBC in Milwaukee (n=88) and Chicago (n=88).
QT interval prolongation and neutropenia are considered to be important identified risks for ribociclib. The approved dosing regimen of ribociclib is 600 mg daily (QD) on a 3 weeks on/1 week off schedule. The purpose of the study is to explore whether a reduced dosing regimen of 400 mg ribociclib orally QD 3 weeks on/1 week off may decrease the risk of QTc prolongation without compromising the efficacy of ribociclib in combination with a non-steroidal aromatase inhibitor (NSAI) in pre- and postmenopausal women with hormone receptor-positive (HR-positive), HER2-negative advanced breast cancer (aBC) who have not received prior therapy for advanced disease.
