RecruitingClinical trialLiquid Biopsy-informed Precision Oncology Study to Evaluate Utility of Plasma Genomic Profiling for Therapy SelectionOverall, this project has three main goals: first, to ascertain the feasibility of the approach and identify whether liquid biopsies can detect actionable mutations that can be utilized to generate precision oncology treatment recommendations. Second, the investigators will investigate whether enacting upon MTB recommendations would improve outcomes in terms of progression-free and overall survival. Third, the investigators aim to determine if molecular profiling via serial plasma tests after initiation of chemotherapy or other targeted treatment is sufficient to determine whether or not a patient is responding to therapy.
