Caris Study Shows AI Improves Lung Cancer Diagnosis
Caris Life Sciences published a study in JAMA Network Open, titled "An AI Approach to Differentiating Lung Squamous Cell Carcinoma From Metastases of Other Origins." This study builds on the body of evidence showing the superiority of Caris' proprietary GPSai algorithm over traditional diagnostic procedures in correctly diagnosing cancer types. This paper demonstrates that by including AI algorithms as part of routine comprehensive molecular profiling, clinicians can uncover clinically significant misdiagnoses in cases labeled as lung squamous cell carcinoma, influencing treatment decisions and patient outcomes. The study comprised 3,958 lung cancer cases submitted to Caris with a diagnosis of SCC. Caris GPSai identified 123 of the 3,958 cases were metastases from other primary sites, including cutaneous, urothelial, head and neck and thymic cancers. The clinical impact of reclassification underscores the power of precision medicine. The study identified 88 patients who had guideline-preferred first-line systemic therapy change recommendations, alerting clinicians that a change in their patients' treatments would achieve better outcomes. According to the CDC website, lung SCC accounts for roughly 21% of all lung cancer cases in the United States. Applying study-specific stats to the wider CDC data for lung cancer in the United States suggests that approximately 1,000 cases each year may be potential misdiagnoses. "Caris GPSai has overturned 3,857 diagnoses across the spectrum of cancer since January of 2024," said Matthew Oberley, MD, PhD, Senior Vice President, Chief Clinical Officer. "By integrating AI-driven tissue-of-origin predictions with comprehensive molecular profiling and pathology, we can give clinicians greater diagnostic confidence and ensure patients receive the most appropriate care."
