Abstract

BACKGROUND: Meta-analyses were conducted to characterize patterns of mutation incidence in non small-cell lung cancer (NSCLC). DESIGN: Nine genes with the most complete published mutation coincidence data were evaluated. One meta-analysis generated a 'mutMap' to visually represent mutation coincidence by ethnicity (Western/Asian) and histology (adenocarcinoma [ADC] or squamous cell carcinoma). Another meta-analysis evaluated incidence of individual mutations. Extended analyses explored incidence of EGFR and KRAS mutations by ethnicity, histology, and smoking status. RESULTS: Genes evaluated were TP53, EGFR, KRAS, LKB1, EML4-ALK, PTEN, BRAF, PIK3CA, and ErbB2. The mutMap highlighted mutation coincidences occurring in ≥5% of patients, including TP53 with KRAS or EGFR mutations in patients with ADC, and TP53 with LKB1 mutation in Western patients. TP53 was the most frequently mutated gene overall. Frequencies of TP53, EGFR, KRAS, LKB1, PTEN, and BRAF mutations were influenced by histology and/or ethnicity. Although EGFR mutations were most frequent in patients with ADC and never/light smokers from Asia, and KRAS mutations were most frequent in patients with ADC and ever/heavy smokers from Western countries, both were detected outside these subgroups. CONCLUSIONS: Potential molecular pathology segments of NSCLC were identified. Further studies of mutations in NSCLC are warranted to facilitate more specific diagnoses and guide treatment.

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

  • KRAS mutations and/or KRAS wild-type amplifications are frequent in colorectal cancer, pancreatic cancer, and NSCLC adenocarcinoma, with varying frequencies by country.

    “KRAS mutations and/or KRAS wild-type amplifications are frequently found in colorectal cancer (US ∼45%, China ∼49% of cases), pancreatic cancer (US ∼90%, China ∼87% of cases), and NSCLC (subtype adenocarcinoma: US ∼35%, China ∼13% of cases)”
  • KRAS mutation accounts for approximately 30% of lung adenocarcinomas in western countries.

    “accounting for ~30% of lung adenocarcinomas in western countries”
  • KRAS mutation accounts for about 10% of Asian lung adenocarcinomas.

    “about 10% of Asian lung adenocarcinomas (2)”
  • KRAS mutation is the most frequent oncogenic mutation in non-small cell lung cancer in western countries.

    “In non-small cell lung cancer (NSCLC), the most frequent oncogenic mutation in western countries is KRAS”

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.
