Researchers at Dana-Farber Cancer Institute have developed SWIFT-seq, a blood test that uses single-cell sequencing to profile circulating tumor cells and could replace painful bone marrow biopsies for multiple myeloma diagnosis and monitoring.
The test successfully captured circulating tumor cells in 90% of patients with MGUS, SMM, and multiple myeloma, with detection rates of 95% in SMM patients and 94% in newly diagnosed multiple myeloma patients.
SWIFT-seq provides comprehensive genetic profiling, tumor growth assessment, and prognostic gene signatures from a single blood sample, offering superior accuracy compared to traditional FISH testing methods.
The breakthrough could transform patient care by enabling routine, non-invasive monitoring and risk stratification while providing novel insights into myeloma biology that may lead to new therapeutic approaches.
