Abstract

Osteosarcomas are aggressive bone tumours with a high degree of genetic heterogeneity, which has historically complicated driver gene discovery. Here we sequence exomes of 31 tumours and decipher their evolutionary landscape by inferring clonality of the individual mutation events. Exome findings are interpreted in the context of mutation and SNP array data from a replication set of 92 tumours. We identify 14 genes as the main drivers, of which some were formerly unknown in the context of osteosarcoma. None of the drivers is clearly responsible for the majority of tumours and even TP53 mutations are frequently mapped into subclones. However, >80% of osteosarcomas exhibit a specific combination of single-base substitutions, LOH, or large-scale genome instability signatures characteristic of BRCA1/2-deficient tumours. Our findings imply that multiple oncogenic pathways drive chromosomal instability during osteosarcoma evolution and result in the acquisition of BRCA-like traits, which could be therapeutically exploited.

  • Osteosarcoma development can be described by the conjunction of oncogenic events initiating malignant transformation, progressive increase of genetic aberrations with increasing proliferation of cells committed to the osteoblast lineage during bone growth, and involvement of a permissive microenvironment that is a prerequisite for cancer cell growth.

    “Osteosarcoma development can be described by the conjunction of multiple factors: oncogenic events that initiate malignant transformation, a progressive increase of genetic aberrations with the increasing proliferation rate of cells committed towards the osteoblast lineage during bone growth 44 , and involvement of a permissive microenvironment, which is a prerequisite for the growth of cancer”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
