Prospective Clinical Study of Precision Oncology in Solid Tumors

Abstract

Systematic studies evaluating clinical benefit of tumor genomic profiling are lacking. We conducted a prospective study in 250 patients with select solid tumors at the Cleveland Clinic. Eligibility required histopathologic diagnosis, age of 18 years or older, Eastern Cooperative Oncology Group performance status 0-2, and written informed consent. Tumors were sequenced using FoundationOne (Cambridge, MA). Results were reviewed at the Cleveland Clinic Genomics Tumor Board. Outcomes included feasibility and clinical impact. Colorectal (25%), breast (18%), lung (13%), and pancreatobiliary (13%) cancers were the most common diagnoses. Median time from consent to result was 25 days (range = 3-140). Of 223 evaluable samples, 49% (n = 109) of patients were recommended a specific therapy, but only 11% (n = 24) received such therapy: 12 on clinical trials, nine off-label, three on-label. Lack of clinical trial access (n = 49) and clinical deterioration (n = 29) were the most common reasons for nonrecommendation/nonreceipt of genomics-driven therapy.
