All tumor sequenced Complementary CGH Actionable Targets detected by CGH

Is CGH-array has additional value to Oncomine Focus assay to screen tumors?

4/82 cases : - PTEN homoz del - AKT2/VEGFA amp - AR amp - BRCA2 homoz del

Conclusion : In our series, CGH-array yields up only few additional relevant alteration when no new targetable alteration is detected by Oncomine Focus panel

Take home messages

– Globally Oncomine focus panel yield allows to identify > 37% of tumors with at least 1 actionable alteration

– The RNA panel is optimized for non epidermoid NSCLC theranostic screening

– Under-exploitment of panel in our series – Screening yield in a trial depends on panel volume as number of

potential drugs available – Oncomine Knowledge base Reporter is an efficient and intuitive

tool for screening clinical trials
