Disease state

EGFRm NSCLC is a distinct disease1,2*

In locally advanced, unresectable
stage III NSCLC, EGFR mutations
are associated with increased risk
of metastatic recurrence,
including CNS metastases,
compared with wild-type disease2,3†‡

*Park et al (2019) was a retrospective analysis that examined the relationship between EGFR mutations and clinical outcomes in patients with stage III nonsquamous cell lung cancer treated with cCRT. Data from 117 patients treated at Samsung Medical Center in Korea from 2008 to 2013 were analyzed for response rates and recurrence rates according to EGFR mutation status.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.2

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.3

Strong partnerships across the MDT as well as reflexive molecular testing have been shown to help guide appropriate treatment for eligible patients across stages of NSCLC and can help decrease turnaround times.6

  • 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=0.00027*

*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. 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.7
