Announcement of Analytical Validation for SPOT-MAS on Five Cancers Lacking Standard Screening (LSS)

We previously developed a SPOT-MAS assay to capture ctDNA signatures from 05 common cancer types (breast, lung, liver, colorectal, and stomach) and successfully facilitated early-stage detection in both retrospective (1) and prospective validation (2) studies.

The recent study published in Future Oncology, “Evaluation of a Multimodal ctDNA-Based Assay for Detection of Aggressive Cancers Lacking Standard Screening Tests”, extends the analysis to the 05 lethal LSS (lacking standard-of-care screening) cancers: endometrial, esophageal, head and neck, ovarian and pancreatic (3).

The study revealed numerous shared ctDNA signals across 05 common cancers and 05 LSS cancers, demonstrating that SPOT-MAS could detect new lethal cancers with 96.2% specificity and 74.8% overall sensitivity.

This proof-of-concept study shows that SPOT-MAS, a non-invasive test trained on five common cancer types, could detect a number of LSS cancer cases, potentially complementing existing screening programs.
