Finding rare cancer cells in blood and biopsy samples
RarecyteFinder: A Bench-to-Bits Toolkit for Label-Free, Whole-Spectrum Analysis of Rare Disseminated Tumor Cells in Liquid and Tissue Biopsies
This project builds a label-free toolkit to find and analyze extremely rare tumor cells in blood and tissue samples from people with cancer.

What this research studies
The team is developing a 'bench-to-bits' approach that combines label-free wide-spectrum imaging with advanced computer algorithms to detect rare disseminated tumor cells in blood, peritumoral tissue, and lymph nodes. The system avoids relying on specific molecular tags and instead uses imaging patterns and machine learning to pick out tumor cells from many normal cells. Researchers will test the toolkit on clinical blood and biopsy specimens from solid tumor patients and refine methods to retrieve identified cells for deeper molecular profiling. This work aims to reduce missed detections and false positives to make detection of metastatic precursor cells more reliable for staging and monitoring.
Who could benefit from this research
Good fit: Ideal participants would be people with solid tumors who can provide blood samples or tissue/lymph node biopsy specimens for analysis.
Not a fit: Healthy individuals and people who cannot provide suitable blood or tissue samples, or whose cancers do not shed detectable tumor cells, are unlikely to benefit directly.
Why it matters
Potential benefit: If successful, this could enable earlier and more accurate detection of metastatic tumor cells to help guide staging and treatment decisions.
How similar studies have performed: Existing liquid biopsy methods like ctDNA and some CTC assays have shown promise but often miss very rare cells, and this label-free imaging-plus-AI approach is relatively novel and less clinically proven.
