Filter by:The investigator propose a prospective study using blood samples (liquid biopsy) of estrogen receptor (ER)-positive metastatic breast cancer (MBC) patients to understand the prevalence of estrogen receptor 1 (ESR1) mutation variants and the correlation with hormonal therapy (HT)-based treatment resistance in Asian ER-positive/human epidermal growth receptor-2 (HER2)-negative MBC population.
The purpose of this two part multicenter, randomized, double-blind, placebo-controlled, Phase III study is to evaluate the efficacy and safety of alpelisib compared to alpelisib matching-placebo in combination with trastuzumab and pertuzumab as maintenance treatment of patients with HER2-positive advanced breast cancer whose tumor harbors a PIK3CA mutation following induction therapy with a taxane in combination with trastuzumab and pertuzumab. Part 1 is the open-label, safety run-in part of the study, designed to confirm the recommended phase 3 dose (RP3D) dose of alpelisib in combination with trastuzumab and pertuzumab. Following Part 1, Part 2 will be initiated, which is the randomized, Phase III part of the study.
This study evaluates the link between muscle health and immune health in breast cancer survivors. Regular exercise is known to improve overall survival in cancer patients but the mechanism is not known. In this study the investigators will evaluate if improving muscle mass and strength via exercise improves the immune system's ability to fight cancer. This is a one armed study where in 30 breast cancer survivors will be recruited to a 4 month exercise intervention. Increase in muscle mass and strength will be correlated with immune cell frequency and function.
Invasive lobular breast carcinoma (ILBC) represents 5-15% of all invasive BCs. The CDH1 gene (OMIM no. 192090), located on the chromosome 16q22.1, encodes for the E-cadherin protein, a key regulator of cell adhesion. Loss of E-cadherin expression is frequently detected in LBC CDH1 germline loss-of-function mutations are associated with the autosomal dominant cancer-predisposition syndrome, hereditary diffuse gastric cancer (HDGC; OMIM no. 137215). The cumulative risk of LBC for women with a CDH1 mutation is estimated to be 42% (95% CI 23% to 68%) by 80 years, when it is a component of HDGC syndrome. Recently, some authors described CDH1 germline mutations in women with in situ or ILBC with early onset (<45 or <50) and bilateral in situ or ILBC with no family history of HDGC. These results are opening a new scenario, suggesting that CDH1 could be a susceptibility gene for LBC in women without a family history of DGC. The first aim of this study is to investigate prevalence of CDH1 in this specific population of women with early onset (<45 or <50) in situ or ILBC, bilateral LBC or LBC with no family history of HDGC.
What is the best dosage of Nab-Paclitaxel for chinese? This study would divide patients into two dosage groups: 1) 125mg/m2, 30 minutes intravenous injection, d1, 8, 21 days for a cycle(clinical use); 2) 125mg/m2 d1, 8, 15, 30 minutes intravenous injection, 28 days for a cycle(guideline recommand). Treatment to disease progression. The efficacy (CR, PR, SD, PD) is evaluated every 2-4 cycles.If the patient withdraws from the trial because he cannot tolerate the toxicity caused by one of the drugs, such as neurotoxicity or bone marrow toxicity, it is recommended to switch to other drugs and follow up to PFS and OS.Each group was planned to include 30 patients.
This study will evaluate the efficacy, safety, and pharmacokinetics of inavolisib in combination with palbociclib and fulvestrant compared with placebo plus palbociclib and fulvestrant in participants with PIK3CA-mutant, hormone receptor (HR)-positive, HER2-negative locally advanced or metastatic breast cancer whose disease progressed during treatment or within 12 months of completing adjuvant endocrine therapy and who have not received prior systemic therapy for metastatic disease.
The purpose of this study is to compare the efficacy of olaparib (MK-7339) plus pembrolizumab (MK-3475) with chemotherapy plus pembrolizumab after induction with first-line chemotherapy plus pembrolizumab in triple negative breast cancer (TNBC). The primary hypotheses are: 1. Olaparib plus pembrolizumab is superior to chemotherapy plus pembrolizumab with respect to progression-free survival (PFS). 2. Olaparib plus pembrolizumab is superior to chemotherapy plus pembrolizumab with respect to overall survival (OS). As of Amendment 3, study enrollment was discontinued. Participants who were receiving benefit from the study intervention could continue treatment until criteria for discontinuation are met. Participants who are on study treatment or in follow-up phase will no longer have tumor response assessments by BICR.
Using decision aids has been demonstrated to support women to make treatment decision effectively. However, these studies focused on the decision of receiving breast conservative surgery or mastectomy, had short term follow-ups on decision satisfaction.The aims of this study were: Evaluate the effect of E-based & personalized breast reconstruction surgery decision aid on women's decision satisfaction and mental health.
The reason for this study is to see if the study drug LY3484356 alone or in combination with other anticancer therapies is safe and effective in participants with advanced or metastatic breast cancer or endometrial cancer.
The purpose of this study is to compare the effect of Eflapegrastim on duration of neutropenia in patients with early-stage breast cancer when administered at varying intervals following Docetaxel and Cyclophosphamide administration.
