Abstract

The anaplastic lymphoma kinase (ALK) rearrangement defines a distinct molecular subtype of non‐small cell lung cancer (NSCLC). Despite the excellent initial efficacy of ALK inhibitors in patients with ALK+ lung cancer, resistance occurs almost inevitably. To date, there is no reliable biomarker allowing the identification of patients at higher risk of relapse. Here, we analysed a subset of 53 ALK+ tumours with and without TP53 mutation and ALK+ NSCLC cell lines by NanoString nCounter technology. We found that the co‐occurrence of early TP53 mutations in ALK+ NSCLC can lead to chromosomal instability: 24% of TP53‐mutated patients showed amplifications of known cancer genes such as MYC (14%), CCND1 (10%), TERT (5%), BIRC2 (5%), ORAOV1 (5%), and YAP1 (5%). MYC‐overexpressing ALK+ TP53‐mutated cells had a proliferative advantage compared to wild‐type cells. ChIP‐Seq data revealed MYC‐binding sites within the promoter region of EML4, and MYC overexpression in ALK+ TP53‐mutated cells resulted in an upregulation of EML4–ALK, indicating a potential MYC‐dependent resistance mechanism in patients with increased MYC copy number. Our study reveals that ALK+ NSCLC represents a more heterogeneous subgroup of tumours than initially thought, and that TP53 mutations in that particular cancer type define a subset of tumours that harbour chromosomal instability, leading to the co‐occurrence of pathogenic aberrations. © 2018 The Authors.

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.
