Filter by:This single arm therapeutic exploratory study of digoxin in patients with advanced or metastatic breast cancer investigates whether cardiac glycosides are able to disrupt CTC clusters in breast cancer patients.
To address the challenges of isolating and analyzing rare cells, this study aims to validate technical diagnostic instrumentation, tests, protocols and analysis to correlate the number of circulating tumor cells present in whole blood for predicting cancer prognosis and treatment efficacy. Investigators propose to enroll and follow cohorts of cancer patients. Blood samples will be collected from these patients at regular intervals as determined by their doctors. The patient's disease progression will be monitored over the lifetime of this study. The specific aims are to isolate, enumerate and analyze the number of circulating tumor cells (CTCs) in patient blood using chip-based sorting, filtration and imaging techniques. Investigators will also use this study to optimize diagnostic instrumentation, test protocols and downstream CTC analysis. Investigators may also correlate the results of these tests with the prognosis of the patients as well as any clinical evidence (e.g. from radiological imaging scans). While investigators focus on prognosis in this study, these correlated tests potentially may also be valuable in future studies for early diagnosis and monitoring of cancer.
To address the challenges of isolating and analyzing rare cells, this study aims to validate the instrumentation, the test protocols, and the analysis of patient's outcome to show the instrument's capability to reproducibly and accurately detect CTCs in cancer patients. In order to facilitate the validation process, investigators will only focus on metastatic patients for whom CTCs supposedly present at higher abundance. Investigators propose to enroll cohorts of metastatic breast cancer patients. Blood samples will be collected from these patients before they start any new line of therapy as determined by their doctors. The specific aims are to isolate, enumerate and analyze the number and/or molecular information of circulating tumor cells in patient blood using microfluidic chip-based sorting, imaging, and molecular profiling techniques. Investigators will use this study to optimize diagnostic instrumentation, test blood processing protocols and CTC analysis algorithm. During this study investigators will collect patients' clinical information related to cancer, as well as the patients' survival status to validate the system's prognosis ability.
