Active clinical trials for "Breast Neoplasms"

This is a multi-center, Prospective, observational study，to evaluate the safety and influencing factors of albumin-bound paclitaxel in the real-world chinese population，and evaluate of the efficacy of albumin-bound paclitaxel in patients with recurrent or metastatic breast cancer and its impact on quality of life.

This is a multi-center, observational study designed to explore the regulatory mechanism of palbociclib correlative pathways in therapeutic process of breast cancer, employing next generation sequencing (NGS) on DNA and RNA. This study also monitor the clonal evolution of genes by tracing the ctDNA.

This is a retrospective, multicenter, non-interventional study for the evaluation of real-world efficacy and safety of T-DM1 in metastatic/relapsed HER2-positive breast cancer as part of the establishment of hospital medical record collection system to evaluate drug effectiveness by Health Insurance Review & Assessment Service (HIRA). The medical records in approximately 1,000 patients of HER2-positive locally-advanced unresectable or metastatic breast cancer, who have received Kadcyla(Trastuzumab Emtansine, T-DM1) previously, will be collected.

The aim of the IMPACT - Implementing Patients' competence in oral breast cancer therapy - study is to evaluate the effectiveness of a standardized patient education and coaching and optional eMBSR for therapy management provided by specially trained oncology nurses regarding persistence rate, side effects management and unplanned therapy interruptions in outpatient oncology care for patients under Abemaciclib treatment.

Triple-negative breast cancer has a poor prognosis and lacks effective adjuvant treatment. A number of preclinical and clinical trials have shown that bisphosphonates have direct or indirect anti-tumor activity, and early use of bisphosphonate adjuvant therapy can prevent cancer recurrence and metastasis including bone metastasis and greatly improve the prognosis of cancer patients. Bisphosphonates have the advantages of low cost, low toxicity, and strong tolerance and can be used as an auxiliary treatment for triple-negative breast cancer. The preliminary study found that bisphosphonates can be chimeric with erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor, which can synergistically inhibit the in vitro tumor formation of cancer (such as non-small-cell lung cancer and breast cancer) cells and the growth of transplanted tumors. Therefore, the purpose of this multi-center prospective real-world study was to further investigate the effects of bisphosphonate adjuvant therapy on breast cancer.

This is a retrospective study on evaluation of the efficacy and the safety of a hypofractionated radiotherapy course with weekly concomitant boost for breast cancer patients treated with conservative breast surgery .

The Neutrophil to Lymphocyte Ratio (NLR) is a frequently used biomarker of the systemic inflammatory response and is considered one of the most sensitive markers of inflammation. Many studies have documented the association between the use of opioid drugs in the acute phase -as it can be considered the use during general anesthesia- and the increase of the NLR value. Such increase could determine a temporary phase of immunodepression in the immediate post operative period with consequent increase of the inflammatory state. This study intends to assess whether different anesthetic techniques can be associated with different variations of the intra-patient NLR value between pre- and post-surgery. Patient will be randomized to receive either local regional anesthesia protocols with thoracic wall blocks (PEC I and serratus plane block) associated with opioid-free general anesthesia (PECS + Opioid-free GA) or general anesthesia.

Breast cancer is the most common malignant tumor in women worldwide,and there exist a large part of patients need to receive neoadjuvant chemotherapy(NAC) before the curative surgery.Circulating tumor DNA(ctDNA) is the circulating free DNA in the blood that originates from cancers,and it can be detected by modern technologies in plasma.In this prospective study,investigators aim to observe the correlation between tumor response to neoadjuvant chemotherapy and ctDNA.

To explore the genetic background of patients with HER2 positive breast cancer that benefit from trastuzumab combined with neoadjuvant chemotherapy, identify clinically actionable mutations that associated with trastuzumab resistance or drug efficacy, we designed this Observational phase II trial. The primary endpoint is genetic profile of HER2+ breast cancer patients treated with trastuzumab combined neoadjuvant chemotherapy. Secondary endpoints included pathological complete response (pCR) rate and safety.

The current observational study aims at analysing current semiology on breast cancer patients aiming at noting indicators and signs with significant relationship with the disease outcomes. To reach the primary objective, of identifying most prominent indicators and signs, a study group of at least 100 female patients with breast cancer diagnosis will be recruited to participate voluntarily. The study group will include at least 20 patients with metastatic cancer and 30 patients with indication to adjuvant chemotherapy. Their physical activity habits and lifestyle will be noted. The observational study will consist in the periodic registration of the overall physical and psychological condition. The variables and tests below will be measured and registered, periodically: periodical assessment of the quality of life periodical assessment of the fitness status of the subjects assessment of changes in bone density/progression of osteoporosis assessment of changes in cognitive function assessment of sleep disorders The collected results will be statistically analysed, in order to: Identify variables that are statistically significantly different from expected values quantify statistically significant differences, whenever possible The results will be used to better describe the breast cancer population
