arXiv:2606.25762v1 Announce Type: new Abstract: In oncology, access to patient-level data is often restricted. Synthetic data provides an alternative for analyzing treatment effectiveness, but existing methods for synthetic data generation fail to preserve the causal relationships between covariates, treatments, and outcomes, thereby leading to biased estimates of treatment effects. Here, we introduce OncoSynth, a generative, causally-aware machine learning framework designed to produce synthetic cohorts that enable accurate estimation of population- and patient-level treatment effects.

The increasing availability of advanced generative AI methods and the persistent challenge of data access in medical research converge to make synthetic data generation a timely focus.
Accurate synthetic data generation in oncology can accelerate drug discovery and treatment optimization by overcoming data privacy barriers and enabling more robust causal inference.
The ability to reliably create synthetic patient cohorts that preserve causal relationships will significantly improve the quality and ethical scope of medical research, particularly in fields with highly sensitive data.

Oncology research benefits from enhanced data accessibility and more effective treatment effect estimation.
The development of highly personalized treatment regimens becomes more feasible due to the ability to simulate patient responses on synthetic cohorts.
This approach could inspire similar causally-aware synthetic data generation across other sensitive data domains, such as finance or classified defense applications.
