Information from the grid let me know that the tumor was androgen active, glucose active by which and how much each gene was implicated. It will tell you how active your immune system is. A little further research can tell you which genetic mutations have proven susceptible to which chemotherapeutic agents. And could clue you in to which clinical trial might likely benefit you. It can tell you if metformin or statins would likely benefit you.
The decipher score "is determined solely by the genomic characteristics of the tumor" itemized on the Grid labled "Research Use Only."
