Accurate and Reproducible Diagnosis of Canine Soft Tissue Sarcoma Using Mass Spectrometry: A Step in the Right Direction.

In this issue of Cancer Cell, Saudemont et al. describe the real-time ex vivo molecular diagnosis and histologic subtyping of canine soft tissue sarcomas using SpiderMass, a technology using water-assisted laser desorption/ionization mass spectrometry. In the future, SpiderMass has the potential to aid in diagnosis and intraoperative margin assessment.
