Abstract

Background Patients with non-small-cell lung cancer harbouring mutations in the epidermal growth factor receptor (EGFR) gene respond well to the EGFR-specific tyrosine kinase inhibitor gefitinib. However, whether gefitinib is better than standard platinum doublet chemotherapy in patients selected by EGFR mutation is uncertain.Methods We did an open label, phase 3 study (WJTOG3405) with recruitment between March 31, 2006, and June 22, 2009, at 36 centres in Japan. 177 chemotherapy-naive patients aged 75 years or younger and diagnosed with stage IIIB/IV non-small-cell lung cancer or postoperative recurrence harbouring EGFR mutations (either the exon 19 deletion or L858R point mutation) were randomly assigned, using a minimisation technique, to receive either gefitinib (250 mg/day orally; n=88) or cisplatin (80 mg/m(2), intravenously) plus docetaxel (60 mg/m(2), intravenously; n=89), administered every 21 days for three to six cycles. The primary endpoint was progression-free survival. Survival analysis was done with the modified intention-to-treat population. This study is registered with UMIN (University Hospital Medical Information Network in Japan), number 000000539.Findings Five patients were excluded (two patients were found to have thyroid and colon cancer after randomisation, one patient had an exon 18 mutation, one patient had insufficient consent, and one patient showed acute allergic reaction to docetaxel). Thus, 172 patients (86 in each group) were included in the survival analyses. The gefitinib group had significantly longer progression-free survival compared with the cisplatin plus docetaxel goup, with a median progression-free survival time of 9.2 months (95% CI 8.0-13.9) versus 6.3 months (5.8-7.8; HR 0.489, 95% CI 0.336-0.710, log-rank p<0.0001). Myelosuppression, alopecia, and fatigue were more frequent in the cisplatin plus docetaxel group, but skin toxicity, liver dysfunction, and diarrhoea were more frequent in the gefitinib group. Two patients in the gefitinib group developed interstitial lung disease (incidence 2.3%), one of whom died.Interpretation Patients with lung cancer who are selected by EGFR mutations have longer progression-free survival if they are treated with gefitinib than if they are treated with cisplatin plus docetaxel.Funding West Japan Oncology Group (WJOG): a non-profit organisation supported by unrestricted donations from several pharmaceutical companies.

  • First-generation EGFR TKIs gefitinib and erlotinib have shown improved efficacy and tolerability compared with chemotherapy in phase III trials.

    “have shown improved efficacy and tolerability compared with chemotherapy in numerous phase III trials”
  • Eight randomised controlled phase III trials have demonstrated that first-generation or second-generation EGFR-TKIs represent the best first-line treatment option in patients with advanced NSCLC whose tumours harbour EGFR mutations, when compared with chemotherapy, because they significantly improved the RR and PFS.

    “Eight randomised controlled phase III trials (table 1) have demonstrated that first-generation or second-generation EGFR-TKIs represent the best first-line treatment option in patients with advanced NSCLC whose tumours harbour EGFR mutations, when compared with chemotherapy, because they significantly improved the RR and progression-free survival (PFS).4–11”
  • Patients with EGFR-mutant NSCLC usually respond to first-generation TKIs but most progress after about 9-14 months.

    “Unfortunately, whilst patients with EGFRm+ tumors typically show good initial responses to first generation TKIs, most patients who respond to therapy ultimately develop disease progression after about 9-14 months of treatment (7-11).”
  • Most patients with exon 19 deletions or L858R have radiographic responses to gefitinib, erlotinib, and afatinib.

    “Most patients whose tumors harbor exon 19 deletions or L858R EGFR activating mutations have radiographic responses to monotherapy with the reversible adenosine triphosphate (ATP)-competitive EGFR tyrosine kinase inhibitors (TKIs) gefitinib and erlotinib 17–23 and the irreversible EGFR TKI afatinib 24.”
  • Randomized trials show that EGFR TKIs improve response rate and progression-free survival compared with chemotherapy as initial systemic therapy for advanced EGFR-mutant NSCLC.

    “Several randomized clinical trials have demonstrated that EGFR TKIs are more effective, as measured by response rate (RR) and progression free survival (PFS), than chemotherapy when used as initial systemic treatment for advanced EGFR mutant NSCLC (1, 4–9).”

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.
