Harnessing AI for Precision Medicine in Pediatric Oncology

Pediatric oncology teams are increasingly combining AI with integrated genomic and ex vivo functional assays to generate precise, bedside-ready therapy maps that can change near-term treatment choices.

Growing evidence suggests that direct measurement of tumor drug response complements DNA- and RNA-based profiling: ex vivo drug-sensitivity assays can reveal phenotypic vulnerabilities not captured by genomics alone. Several AI frameworks have been reported to integrate multi-omic and phenotypic signals to prioritize agents and combinations.

In practice, variant-interpretation tools assign pathogenicity and functional-impact scores while multi-omic layers incorporate copy-number, expression and epigenetic signals. Therapeutic-prioritization algorithms then weight variant calls against assay-derived drug responses—down-weighting private or low-confidence calls and up-weighting concordant functional hits. Genomics-only pipelines infer mechanism but often fall short of predicting actual drug sensitivity, so genomic interpretation and functional evidence are best used complementarily in clinical workflows.

Some AI systems adapt to patient-level inputs and update recommendations as new assay results or outcome data are added; continuous-learning implementations and clinical validation remain nascent and should be documented in primary technical studies or regulatory filings.

Operationalizing this approach requires viable-specimen logistics, standardized ex vivo assay protocols, secure data-harmonization and normalization pipelines, and user-facing outputs formatted as ranked therapy maps with confidence scores and concise rationales for tumor-board review. Together, these capabilities can shorten the interval to more tailored therapy selection at the bedside.

Key Takeaways:

• AI combined with ex vivo functional testing augments genomic interpretation to create individualized therapy maps with actionable rankings.
• Operationalizing the approach requires coordinated specimen logistics, harmonized data pipelines and tumor-board–ready AI outputs.
• Pediatric-specific consent models, ethical governance and outcome registries are essential for safe, evidence-building deployment.
