Is There Value in Molecular Profiling of Soft-Tissue Sarcoma?

Opinion statement

Soft-tissue sarcomas represent a heterogeneous group of diseases accounting for up to 1% of cancer in adults and 15% of cancer in children. Introduction of next-generation sequencing (NGS) technologies has allowed to gain additional insight into the genetic diversity and complexity of sarcomas, including the potential therapeutic implications of some genetic alterations.

Two large studies have investigated the role of targeted NGS to identify actionable mutations in patients with soft-tissue sarcomas. In these two studies, actionable alterations were identified in up to 50% of patients. Retrospective data suggest that genomically guided treatments may be associated with substantial clinical benefit in sarcoma patients with advanced disease. However, prospective data are lacking. The MULTISARC is a randomized phase 3 investigating the potential of NGS implementation to improve outcome of metastatic sarcoma patients.

Overall, a significant proportion of soft-tissue sarcoma bears potential targetable genomic alteration that can be identified through NGS. There is still a lack of evidence to support routine implementation of NGS for the management of sarcoma patient. The MULTISARC randomized trial which randomized patients to tumor genetic profiling or not might confirm the role of NGS to improve outcome of metastatic sarcoma patients through the identification of additional genomically guided lines of treatment.
