Active clinical trials for "Breast Neoplasms"

Breast cancer is the most common cancer in Taiwanese women. Most of them were diagnosed in relatively early stages. Only 700 metastatic breast cancer were registered in Official Cancer Registration 2012, while more than11,305 were registered as early breast cancer. With broadly application of aromatase inhibitors, hormonal-receptor-positive breast cancer patients can survive longer and longer. However, there is no prevalence of metastatic breast cancer can be available yet. NHIA database coverage is more than 90% population in Taiwan, thus it can be an appropriate surrogate of prevalence. In this retrospective database analysis, we will explore the real world experience on aromatase inhibitor use for breast cancer in Taiwan.

assess the validity of applying the bioscore system to predict the disease-free survival (The percentage of people in a study or treatment group who have not experienced disease relapse in a defined period of time.) in breast cancer patients presenting to our

Neoadjuvant chemotherapy (NAC) is widely used as an efficient breast cancer treatment. Ideally, a pathological complete remission (pCR) can be achieved. With improvements in molecular typing guided NAC and targeted therapies, there has been dramatic improvement in pCR rates, especially among triple-negative and human epidermal growth factor receptor 2 positive breast cancers. Rates of pCR in these groups of patients can reach 60% or higher. NAC has significantly promoted the loco-regional de-escalating treatment of breast cancer, and the need for breast surgery in NAC cases with pCR has been questioned, especially in patients undergoing breast-conserving surgery with whole breast radiotherapy. The main impediments for potential elimination of breast surgery have been the fact that conventional and functional breast imaging techniques are incapable of accurate prediction of residual disease. However, imaging-guided minimally invasive biopsy (MIB) techniques might have the potential to overcome this impediment. The investigators design and begin a prospective one-armed clinical study to explore the accuracy of MIB in predicting breast pCR after NAC.

Breast cancer is the most common cancer in French women, with 52000 new cases each year. Shift work and night work is recognized by International Agency for Research on Cancer as a potential risk factor. Epidemiological studies find, for most of them, an increased risk of breast cancer compared with general population. Physiological hypothesis rely on the melatonin role in defense against tumorigenesis. According to High Authority of Health clinical good practice guidelines, the risk does not justify more screening than the organized screening. We do not have information about awareness level of workers in health structures, specially in the Hospices Civils de Lyon. Investigators would like to know how employees take part to breast cancer screening, specially in night workers. This study, as a survey, is a first step to evaluate the need for specific actions to increase the participation to breast cancer screening.

This study is designed to evaluate the frequency and presentations of chronic persistent pain in patients after breast cancer surgery at our tertiary care hospital. Results of this study will help us to understand the magnitude of problem in our population and making institutional guidelines for appropriate management of such patients.

This is a cohort study, applied research and T3 translational genomics to estimate the impact of genetic risk for breast cancer detection in the screening program. The study group base consists of 28 389 female participants, currently in the age-group 22-79, in the Biobank of Estonian Genome Centre. The study is aimed to demonstrate the usability of personalised approach for adjusting and stratifying screening recommendations, based on predicted genetic risk estimates for breast cancer in the situation, where the genome data could be available from all women who have given informed consent for that. The project includes both the detection of moderate and high hereditary breast cancer risk carriers as well as high risk polygenic risk-score (consisting several single nucleotide polymorphisms) carriers among healthy individuals for application of personalised prevention and screening strategies.

The purpose of the study is the identification and quantification of protein expression level in breast cancer tissues. The imaging system is intended for diagnostic use as an aid to the pathologist in the detection, counting and classifying her2 immunohistochemical (IHC) stained samples.

National, prospective, multicentre, non-interventional epidemiological study, conducted among oncologists and breast surgeons in community and university hospitals, from the public sector in Algeria. The study will collect information on the characteristics, and breast carcinomas patterns of patients whose breast cancer diagnosis was confirmed by an anatomopathologist. The study will be conducted over a representative, but not exhaustive sample of Algerian female patients.

Taste disorders in cancer patients during chemotherapy could be consider as multifactorial disease, it is related with changes of food consumption. Approximately 36-69% of the patients under chemotherapy suffer oral toxicity or dysgeusia A prospective case- only observational study was conducted in patients of the Hospital General de México for two years. A self-reported taste survey was used, and patients scored their results in a Likert scale.

In this study, investigator propose to assess the prevalence of pelvic static disorders in women undergoing adjuvant hormone therapy for localized breast cancer and to assess the overall quality of life in these patients
