Abstract

Therapy targeted against the epidermal growth factor receptor (EGFR) has demonstrated dramatic tumor responses and favorable clinical outcomes in a select group of non-small cell lung cancer (NSCLC) patients whose tumors harbor EGFR activating mutations. The best characterized of the mutations conferring sensitivity to EGFR tyrosine kinase inhibitors (TKIs) are deletions in exon 19 and a point mutation in exon 21 (L858R). Likewise, the most common mutation that confers resistance is the T790M point mutation. However several other mutations have been reported and several have been characterized as regards their role in sensitivity or resistance to EGFR TKIs. Resistance to the EGFR TKIs erlotinib and gefitinib, and the newer irreversible EGFR TKIs is a problem of fundamental importance. Recognition of the presence and significance of specific EGFR mutations is important for appropriate therapeutic implementation of EGFR TKIs and research and development of mutation-specific inhibitors. We summarize the literature and present an overview of the subject of less common EGFR mutations and their clinical significance, with an emphasis on EGFR TKI sensitivity or resistance.

Recomputing p-values needs the paper’s full text.

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?

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.
