Filter by:In this observational prospective studi patients with invasive breast cancer no more than 5 cm and clinically node negative, scheduled for conservative surgery and Sentinel Node Biopsy (SNB), are enrolled in the protocol if they have 1-2 sentinel lymphnodes (SLNs) with macrometastases. SLN status will be checked on definitive sections.
Being a mechanistic study, this work aims to figure out "the role of the cytoplasmic mRNA deadenylase CNOT7 expressed protein on NK cell resistance in metastatic BC". In other words, to explore, whether, "CNOT7 contributes to metastasis in Egyptian female metastatic BC patient's cohort, through NK cell resistance, or not."
Perioperative SARS-CoV-2 infection significantly increases the risk of postoperative complications and mortality, while also exerting long-lasting impacts on multiple organs and systems. Due to the curtailment or cessation of non-emergency surgeries during the initial phase of the pandemic, there is a lack of evidence regarding the optimal timing and medium- to long-term postoperative outcomes of surgical intervention in breast cancer patients with prior SARS-CoV-2 infection, particularly after vaccination. We aim to investigate whether prior SARS-CoV-2 infection increases the risk of postoperative adverse outcomes in breast cancer patients and determine the optimal timing for surgical intervention during the pandemic, as well as to longitudinally assess the evolution of postoperative adverse outcomes within one year after COVID-19 and identify associated risk factors.
For patients refusing implants for breast reconstruction after cancer surgery, autologous tissue flap reconstruction using the latissimus dorsi muscle is an alternative. Conventional surgery leaves a long incision on the back, affecting aesthetics and quality of life. Minimal access techniques result in a smaller, more concealable scar. While previous studies suggest its safety and effectiveness, most are retrospective. To further validate patient satisfaction and short-term outcomes, a prospective, randomized controlled trial comparing minimal access with conventional surgery is planned. The primary endpoint is Breast Q-satisfaction with back score at 6 months. Secondary outcomes include other Breast Q subscales, surgical metrics, and complications. The study aims to enroll 94 patients in total, providing evidence for surgical decision-making in breast cancer reconstruction.
To look at the effectiveness of the combination of pembrolizumab, carboplatin, and paclitaxel in participants with stage 1 cT1b-T1cN0M0 Triple Negative Breast Cancer.
This study will determine how the intestinal microbiome differs between patients with obesity and early triple-negative breast cancer who achieve a pathologic complete response from preoperative anti-PD-1 immunotherapy (pembrolizumab) versus patients who do not.
This study is a registered phase III, randomized, open-label, multicenter study to evaluate the efficacy and safety of BL-M07D1 in patients with unresectable locally advanced or metastatic HER2-positive breast cancer who had failed previous treatment with taxanes and trastuzumab.
Development of tools to predict patients chemo-sensitivity and identification of corresponding biomarkers is an urgent challenge for BC patients lacking targeted therapies, such as TNBC, or for patients experiencing relapse after adjuvant chemotherapy or targeted therapies. The refinement of 3D-cultivation techniques, experienced in the last decade, has allowed cultivation of patients-derived cancer cells in organotypic structures, named patient-derived organoids (PDO), which preserve histologic, genomic and transcriptomic features of primary tumors. PDO allow propagation, pharmacological treatment and genetic manipulation of patients-derived cancer cells in a close to physiology setting, thus representing a promising tool in the development of personalized therapies
This clinical trial tests the effectiveness of an interactive time-restricted diet intervention (txt4fasting) in reducing neurocognitive decline and improving survival outcomes after stereotactic radiosurgery in patients with breast or lung cancer that has spread to the brain (brain metastases). Lung cancer and breast cancer are the two most frequent causes of brain metastases. The diagnosis of brain metastases is associated with poorer survival and tumor-induced and treatment-related side effects. Stereotactic radiosurgery is a type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiation to a tumor. Patients who receive stereotactic radiosurgery for brain metastases may experience less neurocognitive side effects than with other types of brain radiation, but may still be at risk for their brain metastases growing, spreading, or getting worse. Patients with obesity and diabetes have been shown to have worse survival and increased radiation-related side effects. Evidence demonstrates that simply changing meal timing can have a positive impact on multiple health outcomes. Time-restricted eating, or prolonged nighttime fasting, has been proven to have positive effects on heart disease risk reduction, weight control management and chemotherapy side effect reduction. Txt4fasting may be effective in decreasing neurocognitive decline and improving survival outcomes in patients undergoing stereotactic radiosurgery for brain metastases from breast or lung cancer.
The purpose of this study is to evaluate the effectiveness of Hemay022 combined with AI (exemestane or letrozole) in the treatment of ER+/HER2+ advanced breast cancer patients based on the progression-free survival (PFS) assessed by the independent review committee (IRC). The second purpose of this study is to evaluate the pharmacokinetics and efficacy of Hemay022 in combination with AI, and the safety of Hemay022 in combination with AI. The trial plans to recruit 339 subjects, who will be randomly divided into two cohorts (the experimental group is hemay022 combined with AI, and the control group is lapatinib combined with capecitabine). During the treatment period, imaging examinations and anti-tumor efficacy evaluations will be performed regularly until the subject develop disease progression or starts receiving other treatments or dies or refuses to come to the hospital for follow-up or the trial is terminated, etc.
