Introduction

Liquid biopsy as a non-invasive method to investigate cancer biology and monitor residual disease has gained significance in clinical practice over the years. Whilst its applicability in carcinomas is well established, the low incidence and heterogeneity of bone and soft tissue sarcomas explains the less well-established knowledge considering liquid biopsy in these highly malignant mesenchymal neoplasms.

Materials and methods

A systematic literature review adhering to the PRISMA guidelines initially identified 920 studies, of whom 68 original articles could be finally included, all dealing with clinical applicability of liquid biopsy in sarcoma. Studies were discussed within two main chapters, i.e. translocation-associated and complex-karyotype sarcomas.

Results

Overall, data on clinical applicability of liquid biopsy in 2636 patients with > 10 different entities of bone and soft tissue sarcomas could be summarised. The five most frequent tumour entities included osteosarcoma (n = 602), Ewing sarcoma (n = 384), gastrointestinal stromal tumour (GIST; n = 203), rhabdomyosarcoma (n = 193), and leiomyosarcoma (n = 145). Of 11 liquid biopsy analytes, largest evidence was present for ctDNA and cfDNA, investigated in 26 and 18 studies, respectively.

Conclusions

This systematic literature review provides an extensive up-to-date overview about the current and potential future uses of different liquid biopsy modalities as diagnostic, prognostic, and disease monitoring markers in sarcoma.
