Filter by:There are several mechanisms concerning pathophysiology of paclitaxel induced peripheral neuropathy. One of the main mechanisms is induction of Schwann cell dedifferentiation by paclitaxel. At the preclinical level, cilostazol potently inhibited paclitaxel-induced dedifferentiation of cultured Schwann cells, yet this positive effect have not been clinically investigated.
The purpose of this research is to develop a culturally adapted "Faith in Action!" curriculum to train lay health navigators to provide breast cancer screening navigation to Korean American women within faith-based settings and evaluate whether the culturally adapted "Faith in Action!" curriculum increases adherence to breast cancer screening guidelines among Korean American women within faith-based settings in Los Angeles, California. The primary research procedures include trainings and key informant interviews with lay health navigators in faith-based settings followed by a cluster randomized trial to evaluate the intervention.
This study aims to identify possible set of inflammatory biomarkers before, during and after anthracycline-based chemotherapy in breast cancer patients to identify (sub)clinical chemotherapy-related cardiac dysfunctionCRCD to identify patients who would benefit from additional cardioprotective therapy.
A recent consensus study suggested that understanding the impact of exercise on the tumor microenvironment and therapy effectiveness is paramount and should be considered as a research priority. Therefore, the research team intends to address some of the scientific challenges proposed, which represent clear gaps in the current knowledge. The investigators propose a randomized controlled trial conducted during all neoadjuvant treatment duration that aims to evaluate and compare the effects of two different exercise protocols (aerobic and resistance training) against a relaxation control group on Ki-67% changes as the main outcome in breast cancer patients. Secondary outcomes will be body composition; resting metabolic rate; physical fitness; quality of life, fatigue, depression/anxiety; accelerometry data (physical activity levels, sedentary time); sleep quality; tumor biology (size, hypoxia, and immune profile); glycemic, lipid, and inflammatory profile. This project will help not only researchers with the design of future exercise intervention protocols but will also help exercise physiologists in the decision-making process when defining training programs. Moreover, the investigators expect that this research program will encourage more cancer patients to exercise. The team expects that patients with breast cancer engaging in structured exercise will show a more marked decrease in Ki-67, tumor size, and hypoxia and increase the tumor-infiltrating lymphocytes (TILs) compared to controls. The investigators anticipate a more noticeable decrease in the preoperative endocrine prognostic index (PEPI) score and in the Residual Breast Cancer (RCB) in both training groups (respectively with hormonal and chemotherapy). Also, frequent declines in physical fitness are expected to be mitigated in exercisers. It is hypothesize that aerobic training will ameliorate cardiorespiratory fitness and fat mass, while the effects of resistance training will be more relevant for muscle strength, muscle mass, and bone health. Both exercise groups will show greater improvements in quality of life, fatigue, depression, anxiety, and sleep quality. Regarding glycemic, lipid, and inflammatory profiles, the investigators expect to see more favorable changes in both training groups, with a more evident decrease in fasting glucose and insulin, HbA1c%, total and LDL-cholesterol, and triglycerides, and the increase in HDL-cholesterol. The increase in C-reactive protein (CRP), tumor necrosis factor -α (TNF-α), interleukin-6 (IL-6), IL-8, IL-1β, IL-1ra, and insulin-like growth factor-1 (IGF-1) and the decrease in brain-derived neutrotophic factor (BDNF), IL-12p70, IL-10, oncostatin M will be smaller in exercise groups.
Extracorporeal Shock Wave Therapy (ESWT); It is a treatment method in which high-intensity pressure waves are applied to the desired point in the body. It has been used in the treatment of kidney stones in previous years, and changes in bone tissue have been observed . Today, it is used in musculoskeletal diseases such as plantar fasciitis, epicondylitis, achillestendinitis, and osteoarthritis. The main mechanism of action of ESWT is not clearly known, but many studies have shown that it stimulates the early release of angiogenesis-related growth factors such as endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF) and increases blood circulation with induced neovascularization, resulting in cell proliferation and tissue growth. It has been shown to increase regeneration . It has been found to be effective in lymphedema with neovascularization and lymphatic channel synthesis . In the literature, there are studies investigating the additional contributions of complex decongestive therapy combined with ESWT in patients with lymphedema.
Hormone therapy is recommended for five years in all patients with hormone receptor-positive breast cancer, but there is no consensus on its duration in low-risk tumours and especially in postmenopausal women. Adjuvant endocrine therapy (ET) is associated with substantial side effects and long-term decreased quality of life. Moreover, while it has been shown that ET provides a real benefit in reducing the relapse rate over time, the deterioration in quality of life may also have a negative effect on patient adherence to treatment. It is therefore important to offer treatment to women with low-risk cancer less intensive treatment strategies. If recent trials tested longer durations as compared to 5 years for high-risk cancers, older trials have tested shorter durations. The 5-year duration appeared at that time as the gold standard because of optimal benefit-risk ratios of tamoxifen among high-risk patients. However shorter treatments of 2-3 years were already associated with substantial benefits and may be enough for very low risk patients.
Breast cancer is the most frequently occurring cancer, assuming that it accounts for 29% of all new cancers in women (European Cancer Information System). The number of long-term survivors is increasing rapidly due to improving accuracy of the detecting methods, the early diagnosis and advances in cancer treatment. The International Consortium for Health Outcomes Measurement Initiative described upper limb (UL) function as the health outcome that matters most for breast cancer survivors (BCS). 50% of BCS at 6 months post-radiotherapy suffer from of decreased UL function, i.e. difficulties in performing activities of daily living with the upper limb. Patients experiencing UL dysfunctions and other problems are less likely to be physically active. Given that physical inactivity is associated with an increased risk of mortality after breast cancer, taking away the barriers to physical activity (e.g. UL dysfunctions) is very important. Identifying these factors contributing to chronic UL dysfunction is important in terms of identifying targets for prospective evaluation and specific treatment approaches at specific time points during breast cancer treatment. There is a need to rethink the follow-up strategy (besides the treatment of the cancer itself) and develop a clinical care pathway consisting of multifactorial screening instruments to identify women and men who are in need of extra rehabilitation efforts and specific rehabilitation goals to alleviate symptoms and side effects experienced by breast cancer survivors. This clinical care pathway should cover all aspects of the International Classification of Function, Disease and Health (ICF), a biopsychosocial framework that conceptualizes a person's level of functioning and bodily structures, activity and participation and contextual factors (including personal and environmental factors). The present study aims to identify the factors, during and after breast cancer treatment, contributing to persistent Upper Limb (UL) dysfunctions.
This Phase III, randomized, two-arm, open-label, multicenter study will evaluate the efficacy and safety of giredestrant plus Phesgo compared with Phesgo after induction therapy with Phesgo plus taxane in participants with human epidermal growth factor receptor 2 (HER2)-positive, estrogen receptor (ER)-positive advanced breast cancer (metastatic or locally advanced disease not amenable to curative treatment) who have not previously received a systemic non-hormonal anti-cancer therapy in the advanced setting.
This is an open-label, multicenter international trial in men and women with primary operable HR+/HER2-, ki67≥20%, grade 2 or 3 and stage II breast cancer to evaluate safety and long-term efficacy of a non-chemo treatment in patients biologically responders to neoadjuvant ribociclib and letrozole. This study aims to evaluate whether chemotherapy could be avoided for initial high-risk clinicopathological breast cancer patients that are converted to low genomic risk assessed by Risk of Recurrence-low (ROR-low) at 6 months of letrozole - ribociclib neoadjuvant treatment by continuing with this treatment in adjuvant setting.
The purpose of this study is to evaluate the efficacy and safety of anlotinib combined with vinorelbine in the treatment of HER2- advanced breast cancer.
