ABSTRACT
PURPOSE:
Sarcomas are a diverse group of malignant tumors that arise from soft tissues or bone. For most advanced cases, there is a substantial need for improved therapeutic options and, therefore, a desire to more precisely tailor therapy in individual cases. In this study, we review our institutional experience with next-generation sequencing (NGS)-based molecular profiling for non-GI stromal tumors sarcomas, with a focus on the clinical utility of the results. PATIENTS ANDMETHODS:
We retrospectively analyzed results of NGS performed on tumors from 114 patients with a diagnosis of sarcoma. A chart review was conducted to review the clinical impact of NGS findings.RESULTS:
A median of three putatively oncogenic gene alterations were identified per tumor sample (range, 0 to 19) and at least one mutation was detected in 96.7% of tumors. Fifty-six patients (49.1%) harbored a finding that was felt to be actionable after review by a molecular tumor board. Five patients (4.4%) had a diagnosis change as a result of NGS findings. In 15 patients (13.2%), therapeutic selection was influenced by NGS findings. Four of 15 (26.7%) of the NGS-influenced systemic therapies resulted in clinical benefit.CONCLUSION:
Putatively oncogenic mutations are readily detected in the majority of sarcomas. Genetic profiling affected the diagnosis and/or treatment approach in a sizeable minority of patients with sarcoma treated at our center. Additional study is required to determine if genetic profiling leads to improved clinical outcomes.
