Digital Precision Oncology with GE HealthCare

A five-year strategic research collaboration on predicting immune checkpoint inhibitor effectiveness and toxicities from real-world electronic-health-record data. Travis Osterman served as principal investigator on the flagship study; the program produced four peer-reviewed manuscripts, multiple abstracts, and a patent.

The clinical problem

Immune checkpoint inhibitors (ICIs) have transformed cancer care. They allow subgroups of patients with previously incurable disease to have longer, higher-quality lives. They also carry the risk of severe immune-related adverse events: hepatitis, colitis, and pneumonitis, some of which are life-threatening and any of which forces discontinuation of an otherwise-working therapy. Oncologists make the treatment decision without a clean way to predict who will respond and who will be harmed. A personalized risk-benefit profile - generated before the first dose - would improve safety, extend treatment duration for responders, and improve clinical trial cohort selection.

The partnership

In 2019 Vanderbilt and GE HealthCare announced a five-year strategic research collaboration centered on this problem (dotmed.com, January 2019). The Digital Precision Oncology study was the flagship: Dr. Osterman as principal investigator from Vanderbilt; Jan Wolber leading on the GE HealthCare side; multi-disciplinary teams on both sides spanning medical oncology, radiochemistry, biostatistics, bioinformatics, and machine learning. The collaboration ran through 2024.

The approach

The team built a machine-learning framework using real-world clinical data already living in the Vanderbilt electronic health record: baseline labs, comorbidities, prior treatments, demographics, and imaging. The cohort grew over the course of the program; the JCO CCI 2024 flagship paper drew on more than 2,200 patients treated with ICIs. Models predicted both efficacy (one-year overall survival) and three major immunotoxicities (hepatitis, colitis, pneumonitis) using only pre-treatment data, generating per-patient risk-benefit profiles. The technical framing was deliberately conservative: short medical-history windows, careful validation, clinically interpretable features over black-box embeddings.

The published results

The flagship paper, Prediction of Effectiveness and Toxicities of Immune Checkpoint Inhibitors Using Real-World Patient Data (Lippenszky et al., JCO Clinical Cancer Informatics, 2024), demonstrated that routinely-collected EHR data is enough to build clinically useful prediction models - across both efficacy and toxicity, without bespoke biomarker panels or unstructured-data extraction pipelines.

From Dr. Osterman's talk Prediction of immune checkpoint inhibitor outcome and side effects by use of machine learning and routine real-world data, ESMO Immuno-Oncology Annual Congress, Geneva, December 2024. US training cohort (~2,200 patients) and German external evaluation cohort (~4,250 patients); AUC scores at 100 days / 1 year / 3 years for overall survival and at 6 weeks / 90 days / 1 year for hepatitis. Models retained a substantial fraction of training-cohort performance on the external cohort - the validation result that made the approach credible beyond a single institution.

An imaging companion paper followed in 2025. Radiomics and Deep Learning Prediction of Immunotherapy-Induced Pneumonitis From Computed Tomography (Smith et al., JCO CCI, 2025) extended the framework to imaging: 2,700 pre-treatment thorax CT volumes for hundreds of patients, with radiomic features and deep-learning models predicting which patients would later develop ICI-induced pneumonitis. External validation across multi-center pan-cancer cohorts was reported at SITC in 2023 (Kiss, Lippenszky et al., abstract 1294).

The patent Model generation apparatus for therapeutic prediction and associated methods and models (Wolber, Csernai, Kiss, Lippenszky, Horváth, Osterman, Park, Smith, Fabbri, LeNoue-Newton, Mittendorf) captures the underlying framework.

Total output

Beyond the published record, the work was covered by ASCO Daily News in two pieces and a podcast, and by Precision Medicine Online in November 2023.

What comes next

The collaboration ended in 2024 as planned, but the line of research continues. Models for ICI-induced hepatitis and colitis are in active development. The clinical insight - that routinely collected EHR data carries enough signal to generate a meaningful risk-benefit profile before the first dose - is now part of a broader research program at Vanderbilt-Ingram on bringing predictive analytics into routine oncology decision-making.

The lesson

The Digital Precision Oncology program is what happens when a careful clinical question gets paired with real-world EHR data, conservative machine-learning methodology, and multi-year institutional commitment. No one paper changed practice. The cumulative work made it credible that pre-treatment risk-benefit prediction for immunotherapy is achievable from the data that already exists in every cancer center's EHR. That credibility is what's required before any of this lands at the bedside.
