Comprehensive analysis of KRAS variants in patients (pts) with pancreatic cancer (PDAC): Clinical/molecular correlations and real-world outcomes across standard therapies.

4641 Background: Approximately 90% of PDAC tumors are driven by activating KRAS mutations. The biological and clinical impact of common KRAS variants (e.g. G12D, G12V, G12R) and less common variants (e.g. G12C, Q61H, Q61R) remains largely unknown despite the emergence of variant-specific treatment strategies. Methods: We retrospectively analyzed real-world outcomes from 1475 PDAC pts who underwent molecular profiling via the Know Your Tumor...
