Active clinical trials for "Breast Neoplasms"

The present study aims at refining the understanding of the effect of pregnancy on breast cancer outcomes in the specific population of BRCA mutated patients with known history of breast cancer.

To evaluate the efficacy and safety of Pyrotinib Maleate Tablets in the treatment of advanced breast cancer patients with positive her-2.

This study evaluates a second review of ultrasound images of breast lesions using an interactive "deep learning" (or artificial intelligence) program developed by Samsung Medical Imaging, to see if this artificial intelligence will help the Radiologist make more accurate diagnoses.

The quality-adjusted life-year (QALY) is the outcome measure of choice in England and Wales for National Institute for Health and Care Excellence (NICE). To be able to conduct a cost utility analysis, QALY data is required. This can either be collected within trial or published data can be used. In the United Kingdom (UK) there is no up to date QALY data for women with early breast cancer treated with surgery followed by radiotherapy. The OSTaRa Study aims to provide up to date QALY data for women in this cohort.

This study aim to investigate the effect of 5-fraction stereotactic partial breast irradiation and whole breast irradiation on patient-reported outcomes, cosmetic outcome, and breast tissue fibrosis in early-stage breast cancer.

In general, brain metastases found after development of neurologic symptoms have poor prognosis. Therefore, the investigators aim to investigate whether regular brain MRI (Magnetic Resonance Imaging) can detect early brain metastases and influence survival through early brain management in HER2-positive and triple negative breast cancer.

Breast cancer (BC) is the most common female malignancy worldwide and the second leading cause of cancer death in women. One in eight women in the United States will develop the illness in their lifetimes. In Egypt, 37.7% of total cancer cases among women is breast cancer. A locally advanced disease is very common and total mastectomy is the most commonly performed surgery. Screening methods and adjuvant therapy following surgery led to a remarkable decrease in mortality. Reliable prognostic and predictive markers are needed to guide the selection of the most appropriate adjuvant therapies for individual patients with breast cancer. In fact, a shift from defining the cancer patients who should receive chemotherapy on the basis of their prognostic characteristics to defining the patients who are likely to benefit most from this modality of adjuvant treatment is currently taking place. Understanding the molecular mechanisms underlying the spread of cancer cells to distant organs, therefore, is a prerequisite for the development of novel cancer therapies.

Aim of work: To estimate the frequency of Cyp2D6*1 and *4 alleles in Egyptian patients maintained on tamoxifen (20 mg/day) for management of ER +ve breast cancer. To measure levels of tamoxifen, 4-hydroxy tamoxifen, N-desmethyl-tamoxifen and 4- hydroxyl-N-desmethyl-tamoxifen (endoxifen) in the serum of these patients. To correlate between the levels of tamoxifen/active metabolite enoxifen ratio and CYP2D6*1,*4 genotyping. To investigate which is more valuable investigatory tool for prediction of the clinical outcome (response and/or toxicity) in these patients; either the measurements related to pharmacokinetics: tamoxifen/endoxifen levels or the pharmacogenetic analysis of CYP2D6 *1,*4.

This was a prospective, single-center clinical study. The study was designed to investigate the relationship between plasma HER2 amplification or specific mutations abundance and clinical response in patients with recurrent or metastatic breast cancer.

This retrospective study evaluated the efficacy and the safety of use of this treatment combined with a taxane for the treatment of HER2-positive metastatic breast cancer and compared the clinical and demographic characteristics of real life patients to the patients of CLEOPATRA.
