Filter by:This research study is being conducted to find out whether changes in household and personal behavior aimed at reducing exposure to environmental chemicals in dust (increased house dust removal efforts/cleaning and hand washing) and consumer products (increased us of personal care and beauty products that are free of chemicals including phthalates, parabens, and phenols) results in lower exposure to environmental chemicals including polycyclic aromatic hydrocarbons (PAHs) and endocrine disrupting chemicals including phthalates, parabens and phenols. These chemicals may have harmful health effects, as they can interfere with normal functions of the body. This study will also assess changes in breast tissue composition to understand the role of environmental exposures in breast cancer risk.
breast cancer occurred 19,219cases in 2015 and is the second most common cancer among female cancers in the country. despite there's been a disease understanding and treatment developing through study, the prevalence and mortality of breast cancer have increased steadily over the last 15 years. In the last 20 years, through random clinical studies of breast cancer, radiation therapy is well-established standard therapy as postoperative supplement of invasive breast cancer and intraepithelial carcinoma but, the need for further study with new questions about radiation therapy has been raised through these studies. according to the prospective study outcome, the radiation treatment of the regional lymph node in breast cancer patients with lymph node positive increases the free-disease survival rate, radiation therapy for regional lymph node is being actively treated than in the past. on the contrary, the results of another study are being reported that treating regional lymph node may increase the risk of arm edema, radiation pneumonia and heart toxicity. In the recently, due to advancement in radiation therapy technique, the implement of new radiation therapy such as IMRT that reducing radiation dose to normal tissues of the axillary, lungs, heart and others has been actively attempted. additional research is needed on dose-fractionation schedule, regional lymph node treatment, post-treatment toxicity of radiation therapy in breast cancer. this study establishes a prospective cohort at breast cancer patients with radiation treatment and analyze the local and regional lymph node control, recurrence, toxicity, radiation planning, clinical data, discover the factors that predict local control, regional control, overall survival, recurrence-free survival, toxicity for treatment, so we intend to construct basic data that establishes a radiation treatment strategy based on comprehensive outcomes and predictors.
Lymphedema is a condition characterized by generalized or regional accumulation of protein-rich interstitial fluid as a result of impaired lymphatic circulation due to congenital or acquired disorders. Lymphedema is diagnosed through evaluations of its clinical criteria. Lymphedema is mostly evaluated through arm circumference measurements, water displacement measurements, tonometry, bioimpedance analysis, ultrasonography (US), computed tomography, lymphoscintigraphy and magnetic resonance imaging (MRI). Targets in the treatment of lymphedema include controlling the symptoms and preventing complications. A multimodal technique called complete decongestive therapy (CDT) is considered the gold standard of the treatment of lymphedema. In the literature, there are also studies showing that stellate ganglion block in breast cancer-related lymphedema treatment improves lymphedema and symptoms. Cervical stellate ganglion block is an invasive method used for the diagnosis and treatment of sympathetic pain and symptoms of upper extremity. Although it can be performed with fluoroscopy, CT and MRI, there has been increasing interest in ultrasound-guided technique since it has been fast, easy and cost-effective for the last few years. However, there are limited studies to provide sufficient evidence for the use of stellate ganglion block as an alternative treatment for lymphedema and detailed studies are needed in this area. The aim of this study is ultrasonographic evaluation of the efficacy of stellate ganglion block in the treatment of patients with breast cancer related lymphedema that is resistant to conservative treatment methods .
Breast cancer is the most common cancer in women worldwide, especially in developed countries. In developing countries, including South Korea, the incidence and mortality rate of breast cancer is rapidly increasing. One of the most important characteristics of breast cancer in South Korea, as well as in other Asian countries, is the younger onset of disease compared to Western. Medical treatment of breast cancer is evolving rapidly, incorporating immune checkpoint blockades and molecularly targeted agents. However, data and knowledge are still limited in terms of molecular characteristics of Asian breast cancer, compared to that of Western countries, and this remains a major hurdle for drug development in Asian breast cancer patients. The primary objective of this study is to elucidate the genetic characteristic of young (<50 years of age) Korean patients with metastatic breast cancer using FoundationOne CDx.
This trial studies how well self-generated survivorship care plans and telehealth education works in improving knowledge and self-efficacy in cancer survivors living in rural areas. Patients living in rural areas often face barriers to survivorship care and report unmet needs. A survivorship care plan created by the patient (self-generated) may help them to better transition from oncology to primary care and improve communication between care teams in order to meet these needs and create better health outcomes. Telehealth is a way of delivering health care services from a distance, including patient education. Combining a self-generated survivorship care plan with telehealth education may help to improve knowledge and self-efficacy in cancer survivors.
Based on the breast cancer organ platform, this experiment establishes a drug sensitivity test method that is closer to the body tumor in breast cancer, provides a basis for the accurate treatment of breast cancer, and discusses the possible mechanism of breast cancer drug resistance.
Background: A person s blood, tissue, and other samples contain DNA. Cancer is a disease of cells that are not working properly. It is caused by changes in DNA that build up. Researchers want to do future studies on DNA changes This may help them learn how to guide treatment for cancer. They need biological samples like tumors, blood, and urine for these studies. Objective: To create a place to collect and store biological samples from people with gynecologic malignancies like breast cancer. Samples from certain relatives of theirs will be collected too. Eligibility: Adults ages 18 and older who are being seen at NIH for breast cancer or other gynecologic malignancy Their biological relatives of the same age Design: Participants will answer questions about their family history. Participants will have a physical exam and medical history. This will include questions about age, ethnicity, and disease history. They will also answer questions about their medical treatments and responses. Participants will give blood and urine samples. Participants may give a tumor tissue sample. This will not be taken specifically for this study. It will be from a previous procedure or one that is already planned. Other samples may be taken only if a procedure is required for treatment. These include bone marrow, cerebrospinal fluid, and other fluids. A group of doctors and other professionals will oversee the sample storage place. The group will review all requests to be sure the use of the specimens is valid.
Globally, breast cancer is the most common cancer and the main cause of deaths due to cancer. This is attributed to changes in reproductive habits as well as an increasingly sedentary lifestyle, with low physical activity and diets rich in saturated fats but low in fiber. While the main focus in many Asian countries is to improve survival from breast cancer by encouraging early detection of the disease and improving access to cancer treatment, it does not reduce the number of women who will be diagnosed with breast cancer in the years to come. Currently, there is an urgent need to develop effective strategies to prevent breast cancer in Asia and beyond. Soy may be an important dietary strategy for breast cancer prevention. Compared to women in the West, Asian women consume up to 10-fold more soy in their diet, which may, in part, explain their lower risk of breast cancer. Soybeans are rich in isoflavones, which can mimic estrogenic activity. In the body, it competes with estrogen and binds to estrogen receptor sites, thereby reducing the effect of estrogen and possibly lowering breast cancer risk. Consistently, research has shown that Asian postmenopausal women who have high soy diets are less likely to be diagnosed with breast cancer. However, researchers have not been able to show that postmenopausal women can reduce their breast cancer risk by increasing soy intake as part of their diets. There are several reasons why these studies have failed to see an effect despite the body of evidence indicating that soy may be protective. Firstly, these are studies of Caucasian women who may have never been exposed to soy, particularly in adolescence, where soy may have the greatest impact. Also, these studies have used soy isoflavone supplements, rather than traditional soy foods made from whole soybeans, which may affect how soy is metabolized in the body. Lastly, the way in which mammographic density measurements were obtained previously could have negatively influenced the study results, such as the use of digitized images of mammogram films rather than raw digital images and the use of semi-automated methods that may be subject to human error and reader variability. Therefore, a well-designed intervention study among Asian women living in Asia, using suitable mammographic density measures as a surrogate marker of breast cancer risk, will best answer these remaining gaps in our knowledge about the soy-breast cancer relationship.
To verify the role of apatinib in neoadjuvant therapy for breast cancer, the investigators designed a prospective, randomized, parallel-controlled phase II/III trial, to investigate the efficacy and safety of apatinib combined with TP (paclitaxel + cisplatin) or TP regimen alone as neoadjuvant therapy for stage II-III breast cancer treatment. 100 cases of eligible patients were diagnosed by core needle biopsy and immunohistochemistry, with the molecular subtypes of triple-negative, HER2+ or Luminal B, evaluated by pathological complete remission (pCR), objective response rate (ORR), adverse events, disease free survival (DFS) and OS, aiming at providing a new way for neoadjuvant therapy in breast cancer and anti-angiogenic treatment of malignant tumors.
This is an open-label, phase I/II double arm study of the SV-BR-1-GM regimen in combination with retifanlimab in patients with metastatic or locally recurrent breast cancer who have failed standard therapy. Patients will receive the SV-BR-1-GM regimen with combination immunotherapy. There will be an initial evaluation of the combination of the SV-BR-1-GM regimen with retifanlimab every 3 weeks. If this is found to be safe and well tolerated in a cohort of at least 12 patients (dose-limiting toxicities (DLTs) in less than 30% of the patients evaluated), then an expansion cohort of up to 24 patients will be treated with that combination. These will be randomized to two regimens differing in the timing of checkpoint inhibitor administration.
