AI-Based Model May Guide Decision-Making in Kidney Cancer Based on CT, EGFR

An artificial intelligence (AI)–based model was able to successfully predict post-operative glomerular filtration rates (GFR) in patients with kidney cancer in ways that clinicians may not be able to; it may also be easily implemented into the treatment landscape, according to Nour Abdallah, MD.

At the 2023 Genitourinary Cancers Symposium, CancerNetwork^® spoke with Abdallah, a postdoctoral research fellow at Glickman Urological & Kidney Institute of Cleveland Clinic, about how AI-GFR prediction models calculated based on pre-operative CT scan and EGFR rate may impact the way patients are treated.

In study presented in a poster session at the symposium, Abdallah and her colleagues compared the AI and clinical model GFR estimations vs measured postoperative GFR based on correlation coefficients. When comparing the measured postoperative GFR, the correlation coefficient was 0.75 for the AI model and 0.77 for the clinical model, respectively. Additionally, the AI and clinical models performed similarly when predicting postoperative GFR below 45 ml/min/1.73m2 (Area under the curve, 0.89 and 0.9, respectively).

Based on the data, Abdallah stated that oncologists could potentially use these AI models for treatment decision-making without the need for additional clinical details or clinician involvement.

Transcript:

This model that we developed was able to behave as accurately as clinical models that were previously validated, whether to predict the post-operative EGFR in value or to predict the cutoff value which was 45.

We feel that this AI model would benefit the patients in a way that does not need any clinician time. It doesn't need any clinical details. It just needs the pre-operative EGFR value and the CT scan. We feel that it can be easily implemented in the health care system at the point of care to help the physician guide the patient towards the best surgery type for [them].
