Filter Characteristics Influencing Circulating Tumor Cell Enrichment from Whole Blood
A variety of filters assays have been described to enrich circulating tumor cells (CTC) based on differences in physical characteristics of blood cells and CTC. In this study we evaluate different filter types to derive the properties of the ideal filter for CTC enrichment. Between 0.1 and 10 mL of whole blood spiked with cells from tumor cell lines were passed through silicon nitride microsiev...
متن کاملFiltration Parameters Influencing Circulating Tumor Cell Enrichment from Whole Blood
Filtration can achieve circulating tumor cell (CTC) enrichment from blood. Key parameters such as flow-rate, applied pressure, and fixation, vary largely between assays and their influence is not well understood. Here, we used a filtration system, to monitor these parameters and determine their relationships. Whole blood, or its components, with and without spiked tumor cells were filtered thro...
متن کاملCirculating tumor DNA outperforms circulating tumor cells for KRAS mutation detection in thoracic malignancies.
BACKGROUND Circulating biomarkers, such as circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA), are both considered for blood-based mutation detection, but limited studies have compared them in a head-to-head manner. Using KRAS (Kirsten rat sarcoma viral oncogene homolog), we performed such a comparison in patients who underwent surgery for suspected lung cancer. METHODS We recru...
متن کاملRapid Isolation of Viable Circulating Tumor Cells from Patient Blood Samples
Circulating tumor cells (CTC) are cells that disseminate from a primary tumor throughout the circulatory system and that can ultimately form secondary tumors at distant sites. CTC count can be used to follow disease progression based on the correlation between CTC concentration in blood and disease severity. As a treatment tool, CTC could be studied in the laboratory to develop personalized the...
متن کاملDetection of Circulating Tumor Cells
The increasing number of treatment options for patients with metastatic carcinomas has created an accompanying need for methods to determine if the tumor will be responsive to the intended therapy and to monitor its effectiveness. Ideally, these methods would be noninvasive and provide quantitative real-time analysis of tumor activity in a variety of carcinomas. Assessment of circulating tumor ...
