  • The T790M mutation is a well-characterized mechanism of acquired resistance to first- and second-generation TKIs, reported to occur in >60% of cases.

    “The “gatekeeper” T790M mutation is a well-characterized mechanism of acquired resistance to first- and second-generation TKIs, which has been reported to occur in >60% of cases.”

    From Afatinib for the treatment of <i>EGFR</i> mutation-positive NSCLC: A review of clinical findings (2020) · cites this paper as [45]

    The Results (Genotypic mechanisms of acquired drug resistance; page unavailable) identify T790M as an acquired resistance mechanism, but report it in 18 of 37 patients (49%), not more than 60%. The Discussion (page unavailable) calls 49% consistent with previously reported incidence. It discusses possible resistance to newer irreversible inhibitors, but does not establish the claimed frequency for first- and second-generation TKIs together. (LLM, conf=0.89)

    Experimental — accuracy not yet measured
  • Acquired resistance to EGFR TKIs occurs in the majority of patients after first-line treatment of EGFRm+ NSCLC.

    “Despite the efficacy of EGFR TKIs in the first-line treatment of EGFRm+ NSCLC, acquired resistance to therapy occurs in the majority of patients.”

    From Afatinib for the treatment of <i>EGFR</i> mutation-positive NSCLC: A review of clinical findings (2020) · cites this paper as [45]

    The Introduction says most EGFR-mutant NSCLCs initially respond to EGFR TKIs but subsequently acquire resistance, and the Discussion describes resistance as occurring after about 12 months of treatment. The paper does not establish that a majority acquire resistance specifically after first-line treatment; its Discussion mentions only two first-line erlotinib cases separately. No page numbers are available in our copy. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The most common mechanism of resistance to first-generation EGFR TKIs is T790M, occurring in approximately 50-70% of patients.

    “The most common mechanism of resistance to first-generation EGFR TKIs is the development of the gatekeeper T790M mutation, which occurs in approximately 50–70% of patients.”

    From Afatinib for the treatment of <i>EGFR</i> mutation-positive NSCLC: A review of clinical findings (2020) · cites this paper as [45]

    The Results (Genotypic mechanisms of acquired drug resistance) report T790M in 18 of 37 patients (49%), more than any other identified mechanism. The Introduction also describes T790M in about half of resistant cancers, but the paper does not establish the claimed 50–70% range. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • In two NSCLC patients without an identified genomic resistance mechanism, histologic transformation from adenocarcinoma to squamous-cell carcinoma was observed, suggesting nongenetic mechanisms of resistance to KRASG12C inhibition may occur.

    “In two patients with NSCLC for whom we were not able to identify a genomic resistance mechanism, we observed histologic transformation from adenocarcinoma to squamous-cell carcinoma, which suggests that nongenetic mechanisms of resistance to KRASG12C inhibition may occur, similar to those observed with other targeted therapies in lung cancer.24-26”
  • After using first-generation EGFR TKIs for approximately 9-14 months, almost all tumors progressed again.

    “after using first-generation EGFR TKIs for approximately 9–14 months, almost all tumors progressed again.111”

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.
