Real World Evaluation of AI-Based Tumor Cell Content Quantification for Molecular Tumor Profiling.

AI software quantifies tumor cells in tissue samples more accurately than pathologist eyeballing, improving precision in cancer diagnosis.

AI-based tumor cell content quantification (AIM-TumorCellularity, PathAI) showed stronger agreement with molecular quantification (Rs=0.63) than pathologist visual quantification (Rs=0.38), with 98.5% sensitivity and 99% specificity on 27,958 annotated cells; pre-analytical factors and specimen type were key contributors to DQ-VQ discrepancies. This record was retained from the prior triage attempt for PubMed pipeline handoff.

Why it surfaced

Accurate tumor cell content estimation is a prerequisite for all NGS-based molecular profiling; visual pathologist quantification is highly variable and limits assay reliability. A real-world validation demonstrating AI superiority over visual quantification at a leading institution directly addresses this bottleneck in precision oncology diagnostics.
