Finding a few tumor cells hidden among billions of blood cells is one of the biggest challenges in liquid biopsy. Circulating tumor cells (CTCs), which break away from primary tumors and enter the bloodstream, can provide important clues about cancer progression and treatment response. However, their extremely low abundance—often only one to ten cells among a billion blood cells—makes them difficult to isolate and accurately identify.
In a new study published in Biomedical Analysis, researchers from Taiyuan University of Technology and Shanxi Bethune Hospital developed a new strategy that combines a microfluidic chip with artificial intelligence to address this challenge. The platform first separates tumor cells from surrounding blood cells according to their physical differences, then uses deep learning to identify the enriched cells from ordinary microscope images. This approach provides a new route toward simpler, less label-dependent CTC analysis.
To the surprise of researchers, certain diets often considered “unhealthy” or “fattening” were associated with better responses to a type of cancer immunotherapy.
"There is a synergistic relationship between the bacteria that reside in our GI tract, and the food we eat,” said Daniela Quail, Associate Professor in the Department of Physiology and Principal Investigator at the Rosalind & Morris Goodman Cancer Institute.
