KRAS Mutations in Non-Small Cell Lung Cancer

Riely, G. J., Marks, J., Pao, W.·2009·Proceedings of the American Thoracic Society

Abstract

Some non-small cell lung cancers (NSCLCs) harbor a single specific mutated oncogene that is thought to be the primary genetic "driver" leading to cancer. The two most commonly mutated oncogenes in lung cancer encode for the epidermal growth factor receptor (EGFR) and KRAS. EGFR kinase domain mutations were only recently identified, but they have already been established in the clinic as valid predictors of increased sensitivity to EGFR kinase inhibitors (gefitinib and erlotinib). By contrast, even though KRAS mutations were identified in NSCLC tumors more than 20 years ago, we have only just begun to appreciate the clinical value of KRAS tumor status. Recent studies indicate that patients with mutant KRAS tumors fail to benefit from adjuvant chemotherapy, and their disease does not respond to EGFR inhibitors. There is a dire need for therapies specifically for patients with KRAS mutant NSCLC. In this review, we summarize the initial discovery of RAS mutations in NSCLC, describe work exploring associations with clinical factors and outcomes, and provide an overview of current approaches to targeting KRAS mutant NSCLC.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • GTP binding to KRAS shifts the active site from an open to a closed conformation, allowing multiple downstream effector pathways including MAPK and PI3K to interact and activate.

    “GTP binding to KRAS shifts the active site from an open to a closed conformation, allowing multiple downstream effector pathways to interact and activate, including the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3K) pathways [12, 13].”
  • In patients with lung cancer harboring KRAS mutations, most mutations occur in codon 12, whereas mutations in codons 13 and 61 are less frequent.

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.
