Official title: Cross-species transfer learning for liquid biopsy-based cancer detection

Funded at University of California at Davis · NIH-11355216 · Data updated 2026-11-12

This project builds a blood test that uses patterns learned from dogs to help find osteosarcoma earlier in children and other patients.

Who could benefit from this research

Could help

Ideal candidates are children and other patients with suspected or confirmed osteosarcoma, or people at high risk who can provide blood samples for testing.

Less likely to help

People without bone sarcoma or those unable or unwilling to give blood samples are unlikely to benefit from this approach.

What this research studies

If you took part, you would give a small blood sample that is scanned with Raman spectroscopy to capture molecular fingerprints. Researchers will train computer models on large collections of dog plasma samples and then fine-tune those models using smaller numbers of human samples, including pediatric samples. They will also run targeted lipid and metabolite tests to make sure the computer-based signals match real biological molecules. The process aims to create a noninvasive liquid biopsy that works across species to improve detection of bone sarcoma.

Why it matters

Potential benefit: If successful, this could allow earlier, less invasive detection of osteosarcoma, improving treatment options and outcomes for patients.

How similar studies have gone: Liquid biopsy and Raman spectroscopy have shown promise in cancer detection, but using large canine datasets and cross-species transfer learning to detect human osteosarcoma is a novel approach.
