Abstract

PURPOSE: To assess the benefits of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors as neoadjuvant/adjuvant therapies in locally advanced EGFR mutation-positive non–small-cell lung cancer. PATIENTS AND METHODS: This was a multicenter (17 centers in China), open-label, phase II, randomized controlled trial of erlotinib versus gemcitabine plus cisplatin (GC chemotherapy) as neoadjuvant/adjuvant therapy in patients with stage IIIA-N2 non–small-cell lung cancer with EGFR mutations in exon 19 or 21 (EMERGING). Patients received erlotinib 150 mg/d (neoadjuvant therapy, 42 days; adjuvant therapy, up to 12 months) or gemcitabine 1,250 mg/m 2 plus cisplatin 75 mg/m 2 (neoadjuvant therapy, two cycles; adjuvant therapy, up to two cycles). Assessments were performed at 6 weeks and every 3 months postsurgery. The primary end point was objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1; secondary end points were pathologic complete response, progression-free survival (PFS), overall survival, safety, and tolerability. RESULTS: Of 386 patients screened, 72 were randomly assigned to treatment (intention-to-treat population), and 71 were included in the safety analysis (one patient withdrew before treatment). The ORR for neoadjuvant erlotinib versus GC chemotherapy was 54.1% versus 34.3% (odds ratio, 2.26; 95% CI, 0.87 to 5.84; P = .092). No pathologic complete response was identified in either arm. Three (9.7%) of 31 patients and zero of 23 patients in the erlotinib and GC chemotherapy arms, respectively, had a major pathologic response. Median PFS was significantly longer with erlotinib (21.5 months) versus GC chemotherapy (11.4 months; hazard ratio, 0.39; 95% CI, 0.23 to 0.67; P < .001). Observed adverse events reflected those most commonly seen with the two treatments. CONCLUSION: The primary end point of ORR with 42 days of neoadjuvant erlotinib was not met, but the secondary end point PFS was significantly improved.

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.
