Leverage Artificial Intelligence to identify Tumor Origin and Guide Treatment with MI GPSai Typically, a Cancer of Unknown Primary (CUP) diagnosis is treated empirically and has very poor outcomes, with median overall survival less than one year1. MI GPSai analyzes genomic and transcriptomic data to match a tumor’s molecular signature across 21 cancer types from the Caris database. MI GPSai is intended to provide additional insight to help oncologists better manage cancers of unknown primary (CUP) or cases with atypical clinical presentation or clinical ambiguity, as identified by the ordering physician. MI GPSai Data Results The MI GPSai algorithm trained on genomic data from 34,352 cases and genomic and transcriptomic data from 23,137 cases, and was validated on an independent data set of 19,555 cases2.

Comprehensive tumor profiling with Caris Molecular Intelligence® performed with MI GPSai provides a comprehensive workup. Ability to identify misdiagnosed patients. Pathology proactively contacts treating oncologists to discuss discordant results to optimize patient care. MI GPSai can be added to any solid tumor order by selecting the appropriate box on the Caris requisition. Results for MI GPSai will appear in the final Caris report, with no additional cost or added specimen requirements. These results will provide additional insight by assessing how closely tumors match the genomic and transcriptomic signatures of cancer types to help you make more informed treatment decisions.
