Filter by:This study is the spatial transcriptomic approach for revealing the resistance mechanism of trastuzumab deruxtexan in HER2 positive breast cancer patients.
The purpose of this study is to determine the safety, tolerability, and recommended dose of ELVN-002 in combination with trastuzumab in participants with advanced-stage HER2-positive tumors and in combination with trastuzumab, and chemotherapy in participants with advanced-stage HER2-positive colorectal cancer and breast cancer.
The aim of this study is to understand whether DWB-MRI (Diffusion Whole Body-Magnetic Resonance Imaging) is useful for early detection of locoregional or distant recurrence and whether early diagnosis influences the prognosis in high-risk populations thanks to the possibility of being able to use a more effective treatment. The primary objective is to evaluate 5-year overall survival (OS) in patients with Human Epidermal Growth Factor Receptor 2 positive (HER2+) or high-risk Triple Negative (TN) undergoing surveillance with DWB-MRI.
This single arm study aims to evaluate the efficacy and safety of a non-surgical approach, consisting of radiotherapy (RT) alone, for patients who have achieved a complete pathological response (pCR) following neoadjuvant chemotherapy (NACT). The study design involves the histological confirmation of pCR using vacuum-assisted biopsy (VABB) or vacuum-assisted excision (VAE) guided by ultrasound. The primary objective is to demonstrate that the non-surgical, RT-only treatment and follow-up approach is not inferior to the traditional surgical approach in patients with pCR after NACT.
This study is designed to compare efficacy and safety of DB-1303/BNT323 versus T-DM1 in HER2-positive, unresectable and/or metastatic breast cancer patients previously treated with trastuzumab and taxane.
The purpose of this study is to compare a special type of mammogram that uses a contrast agent called contrast-enhanced digital mammography with contrast-enhanced digital breast tomosynthesis (CEDM+CEDBT), with breast magnetic resonance imaging imaging (MRI) for predicting the effect of neoadjuvant chemotherapy on pathologic complete response rates. The device used to obtain CEDM+CEDBT images is called Siemens MAMMOMAT. This device produces two-dimensional (2D) images, as in a normal mammogram, but also collects additional images for digital breast tomosynthesis (DBT), which produces a three-dimensional (3D) image of the breast in the form of image slices. DBT allows the radiologist to "see through" the breast tissue for better detection and localization of breast cancer. By looking at both the CEDM images and the CEDBT images, a radiologist may be able to better detect residual breast cancer in a more cost-effective manner. Participation may last up to 18 weeks. Study procedures for this research are: - Undergoing 1-2 mammograms during and/or after your chemotherapy, but before primary breast surgery. - Before each mammogram, have a radiology technician inject a liquid contrast agent by inserting a needle into a vein. The chemotherapy port cannot be used to receive the contrast agent - Let the research team record information from your medical record related to your condition and the treatment you receive. - Give permission to collect leftover tissue from your diagnostic biopsy and breast surgery.
This is a multi-center real-world study, in which patients who meet the inclusion criteria will receive treatment with Pyrotinib + Trastuzumab + Taxanes. Taxanes will be used for 6-8 cycles or discontinued due to intolerable Adverse Events (AEs), after which Capecitabine will be used for rhythmic chemotherapy combined with Pyrotinib + Trastuzumab. The aim is to explore the efficacy and safety of Pyrotinib, Trastuzumab, and Taxanes in treating Trastuzumab-treated HER2+ Advanced Breast Cancer (ABC).
This multi-center observational prospective study will collect real-world clinical and patient-reported outcome data from eligible patients with unresectable or metastatic HER2+ breast cancer who have received one or more prior anti-HER2-based regimens or patients with unresectable or metastatic HER2-low (IHC 1+ or IHC 2+, ISH-) breast cancer who have received at least a prior systemic therapy in the metastatic setting, or developed disease recurrence during or within 6 months of completing adjuvant chemotherapy.
This is a non-interventional observational, multi-center cohort study to evaluate patient-reported outcomes in Chinese HER2+ early breast cancer patients undergoing (neo) adjuvant anti-HER2 based therapy and describe changes over time, from baseline to 12 months.
This is a prospective and observational study, aiming to determine the detection rate and change of CtDNA in blood samples of cancer patients before, during and after neoadjuvant treatment. - Determine the rate of ctDNA positivity at the time before treatment, - Determine the rate of ctDNA positivity at the time during treatment, - Determine the rate of ctDNA positivity at the time after neoadjuvant therapy, whether there is a change in ctDNA expression of the study population during treatment. And aiming to investigate the relationship between ctDNA expression and MRI imaging with pCR response in neo-adjuvant therapy: - Correlation between ctDNA detection and pCR response. Determine the percentage of Positive Prediction Value - PPV, Negative Prediction Value - NPV of ctDNA, - Correlation between MRI imaging and pCR response. Determination of PPV, NPV of MRI - Combination of ctDNA detection and MRI imaging in the prognosis of pCR. Determination of PPV, NPV ratio of ctDNA combined with MRI.
