Disease state

In locally advanced, unresectable stage III EGFRm NSCLC following CRT

EGFR mutations are common in stage III NSCLC and may be driving tumor growth

~1 in 3 patients with stage III NSCLC may have an EGFR mutation1*

Mutations in EGFR activate abnormal cell signaling, which leads to cancer cell proliferation and inhibition of apoptosis2

In locally advanced, unresectable stage III NSCLC, EGFR mutations are associated with increased risk of metastatic recurrence, including CNS metastases,
compared with wild-type disease3,4†‡

*Zhang et al (2016) was a retrospective analysis of 456 studies including patients with NSCLC. Eighty-five studies included patients with stage III NSCLC. Of those patients, 33.8% had an EGFR mutation (95% CI: 29.8, 37.8).1

Kim et al (2023) retrospectively examined the clinical outcomes and recurrence patterns after definitive CRT in patients with unresectable stage III NSCLC according to EGFR mutation status at Samsung Medical Center in Korea from January 2013 to December 2018. EGFR mutations were detected in 71 of 236 patients (30.1%) and the median follow-up duration was 41.7 months.3

Tanaka et al (2015) was a retrospective study of 104 patients with unresectable stage III adenocarcinoma who were examined for EGFR mutation status and received definitive cCRT consisting of platinum doublet chemotherapy in the first-line setting from 2006 to 2013 at Aichi Cancer Center Hospital or Institute of Biomedical Research and Innovation. The study analyzed clinical outcomes and recurrence patterns according to mutation status. Twenty-nine patients (28%) had EGFR-mutated tumors and 75 (72%) were EGFR wild-type.4

Eligible patients with unresectable stage III EGFRm NSCLC have an option for targeted therapy

EXPLORATORY ANALYSIS: NEW CNS LESIONS1

This was a prespecified interim analysis and has not yet been tested for statistical significance.

  • Data maturity was 27% at the time of analysis11
  • To control for the type I error rate, a sequential multiple testing procedure was used for PFS (primary endpoint), OS, and CNS PFS. At this analysis, CNS PFS could not be formally tested for statistical significance because the interim analysis of OS data did not reach statistical significance at a maturity of 20%11
  • All patients underwent MRI brain scans at baseline and at each follow-up during the study. Tumor assessments were performed every 8 weeks until week 48, and then every 12 weeks, until BICR-assessed progression6,11
  • Median duration of follow-up for CNS PFS was 24.6 months (range: 0.0, 60.6) in the TAGRISSO arm and 5.7 months (range: 0.0, 55.1) in the placebo arm11
  • CNS PFS was defined as the time from randomization until the earliest date of CNS objective disease progression or death (by any cause in the absence of CNS progression) regardless of whether the patient withdrew from randomized therapy or received another anti-cancer therapy before CNS progression11

  • Adoption of reflex testing at diagnosis significantly reduced turnaround time for molecular testing results by ~37 days on average in a retrospective cohort study, including 166 newly diagnosed patients with NSCLC of any pathologic stage; P=0.0002*

*Based on a single-center, retrospective study of 220 patients, including 166 patients with newly diagnosed lung adenocarcinoma whose specimens were received for molecular testing over a 3-year period between 2016 and 2018. In 2016, 39 patients had non-reflex ordered testing with an average turnaround time of 52.6 days. In 2017 and 2018, 127 patients and 54 patients, respectively, had reflex-ordered testing at diagnosis with an average turnaround time of 26.5 days and 15.6 days, respectively. A mutation was detected and reported in 62 (48.8%) of 127 reflex-ordered cases, and 10 (25.6%) of 39 non-reflex ordered cases; P<0.05). Reflex-ordered biomarker testing included EGFR, KRAS, BRAF, and ERBB2 gene mutations; MET exon 14 skipping; ALK, RET, and ROS1 gene rearrangements; MET gene amplification; and PD-L1 expression by immunohistochemistry.13
