Active clinical trials for "Breast Neoplasms"

Luminal A breast cancer is a kind of breast cancer with low rate lymph node metastasis and good survival. But in clinical practice, Luminal A breast cancer can present with early, unexpected lymph node metastasis some time, indicates poor survival. Silent information regulator 2 homolog 1 (SIRT1) plays a different role in breast cancer with different molecular typing. Previous study supports a role of SIRT1 protein as tumor suppressor in Luminal A breast cancer, in association with apoptosis-related proteins. The epithelial-to-mesenchymal transition(EMT) process results in loss of cell-cell adhesion, increased cell mobility, and is crucial for enabling the metastasis of cancer cells. But no similar study in Luminal A breast cancer. Hence, this study will 1) investigate the expression pattern of SIRT1 in primary tumor and lymph node metastasis; 2) investigate the different expression pattern of SIRT1 in T2/T3 , lymph node negative tumor and T1, lymph node positive tumor; 3) investigate potential role of SIRT1 enzyme in regulating cell migration and invasion in Luminal A breast cancer cells.

This study will evaluate the cosmetic outcome and examine factors contributing to cosmetic outcome in women treated with lumpectomy or bilateral breast reduction mammoplasty/mastopexy (BRM) followed by hypofractionated whole breast irradiation. Breast conservation is now an established method of treatment for early breast cancer. Because breast conservation is essentially a cosmetic alternative to mastectomy, quality of life, cosmetic outcome and tumor control are all important considerations during comprehensive treatment planning. Irradiation schemes have been demonstrated to be efficacious and with excellent short term cosmetic outcomes. However, their interaction with currently evolving surgical techniques needs to be examined in order to maintain optimal local control while preserving cosmetic outcome.

To evaluate the prevalence of BRCA1/2 mutation of breast cancer patients with family history of breast/ovarian cancer. To evaluate the prevalence of BRCA1/2 mutation of breast cancer patients without family history, but high risk of hereditary cancer. To evaluate the prevalence of BRCA1/2 mutation of family member of BRCA1/2 mutation. To evaluate the prevalence of ovarian cancer of population of above 3 groups.

The primary study endpoint -SoftScan adjunctive accuracy- will be used to test the hypothesis that the adjunctive combination of the SoftScan with x-ray mammography provides diagnostic accuracy that is significantly better than x-ray mammography alone.

To evaluate if there is any imaging characteristic of breast cancers in women younger than 40 years of age.

Breast cancer is the most common type of cancer among women and covers 25% of all cancers. After mastectomy and reconstruction, many patients develop various upper extremity complications such as joint movement limitation, pain, lymphedema, and axillary cord. Because of such upper extremity problems, evaluation and treatment of upper extremity functions are important. Upper extremity functions are generally evaluated with questionnaires filled out by the patients themselves and which reflect their own perspectives subjectively. However, these questionnaires cannot reflect the observations and evaluations of the clinicians. Performance tests are important for clinicians to make decisions. With this study, we want to examine the usability of the FIT-HaNSA test in the evaluation of upper extremity functions in patients with breast cancer. Our hypothesis; The FıtHaNSA test is successful in evaluating the upper extremity function in patients with breast cancer.

To date, few studies have addressed the link between gut microbiota and breast cancer chemotherapy, and previous studies have only provided a link between the gut and breast cancer.

This study aims to investigate if lipid composition mapping using magnetic resonance imaging could improve early and accurate cancer detection in genetic mutation carriers at high risk of breast cancer. It is hypothesised that there is a significant difference in the extent of spatial variation in lipid composition in breast from MRI between genetic mutation carriers and patients with breast cancer.

Objective: To investigate the current clinical practice of sentinel lymph node biopsy (SLNB) in patients with early stage breast cancer in China. Methods: The data of early breast cancer patients who underwent SLNB in 40 Grade III Level A hospitals in China in 2018 will be collected. Different centers, tracer methods, molecular typing and neoadjuvant chemotherapy will be used as stratification factors to analyze the implementation rate, number of detections, positive rate of SLNB and the follow-up treatment.
