In resectable NSCLC

Among patients with resectable NSCLC, adjuvant treatment rates remain low, despite the significant risk of recurrence

Undetectable micrometastases that drive recurrence may remain after complete resection

Despite successful surgery, micrometastases may remain1

*Chouaid et al (2018) conducted a retrospective observational study in 831 patients with complete resection of stage IB-IIIA NSCLC with no information on EGFRm status. Of the 831 patients, 200 experienced metastatic recurrence during the observed study follow-up period.2

Based on a single-center, retrospective review of 1640 patients who had undergone resection for stage I-IIIA NSCLC from a prospectively maintained database to compare patterns of recurrence. 181 of 346 patients with stage IIIA NSCLC (52%) and 257 of 1294 patients with stage I-II NSCLC (20%) developed recurrences. Staging was based on the 7th edition of the AJCC tumor, node, and metastasis classification of lung cancer.3

Based on a single-center, retrospective study of 282 patients with early or locally advanced lung adenocarcinoma; 142 were EGFRm and 140 were EGFR wild-type. The majority of both groups received standard-of-care treatment. Standard-of-care was defined as surgery or RT + cytotoxic platinum-based doublet therapy when appropriate.4

§Overall recurrence across all stages was ~23% in patients who were EGFRm and ~21% in patients who were EGFR wild-type. P-value corresponds to data calculation 21/29=0.72 and 31/32=0.97. The P-value of 0.007 was for the overall population (stage I-III). The only P-value by stage that was significant was for stage I (P=0.02).4

||Based on a meta-analysis that examined the incidence of brain metastases in EGFRm or EGFR wild-type NSCLC. 8152 patients were included from 22 multinational studies. 16 studies included patients with stage IV disease. 2664 patients had an EGFR mutation.5

Hüyük et al (2023) conducted a systematic review and meta-analysis extracting DFS and OS data from 15 studies with a total of 1893 patients with stage I-IIIA NSCLC, with and without occult lymph node micrometastasis/isolated tumor cells, after surgical resection. Meta-analyses for OS and DFS were performed on 14 and 8 studies, respectively. Survival probabilities for OS and DFS at different timepoints were extracted from published survival curves. OS probabilities were reported at every 6 months after surgery until 5-year follow-up for both micrometastasis and no micrometastasis. DFS was reported at every 3 months after surgery for the first 2-year follow-up, and at every 6 months after 2 years of follow-up until 5 years follow-up.6

#According to the American Joint Committee on Cancer, micrometastases are defined as clusters of tumor cells measuring between 0.2 mm and 2.0 mm in greatest diameter, and ITCs are defined as single tumor cells or small clusters of cells, smaller than 0.2 mm in greatest diameter.8

**In patients with stage IB-IIIA, IIIB (T2-3, N2b; T4, N2) NSCLC, NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for NSCLC recommend testing for PD-L1 status, EGFR mutations, and ALK rearrangements.7

*Prevalence per stage: stage I = 20% (19, 20.4), stage II = 18% (14.9, 19.9), and stage III = 18% (17.4, 17.7). Prevalence of EGFR mutations in NSCLC adenocarcinoma was based on data from 2 references: Sholl et al (2015) performed mutation analysis on 1007 cases with confirmed diagnosis of lung adenocarcinoma. Testing was performed on 987 cases for EGFR sensitizing mutations (exon 19 deletions, EGFR L858R mutations, EGFR G719X mutations, EGFR L861Q mutations) and other EGFR mutations (any one or more mutations in EGFR other than exon 19 deletions, L858R mutations, G719X mutations, or L861Q mutations). Out of 987 cases, 331 cases that were analyzed had stage I-III NSCLC and 632 had stage IV NSCLC. D’Angelo et al (2012) analyzed tumor specimens from a cohort of 1118 patients with stage I-III surgically resected lung adenocarcinomas with EGFR exon 19 deletions and L858R mutations only.11,12,15,16

EGFR mutation status and PD-L1 expression overlap was examined in a retrospective analysis of 319 patients with EGFRm NSCLC across all stages. EGFR mutations included exon 19 deletions (n=145), exon 21 L858R mutations (n=121), exon 19 nondeletions (n=26), exon 21 non-L858R mutations (n=3), exon 18 mutations (n=12), and exon 20 mutations (n=8). One patient had both exon 18 and exon 20 mutations and 3 patients had other mutations. PD-L1 expression ≥1% was observed in 86 out of 150 patients with stage IB-III EGFRm NSCLC.13

Reflex testing can help increase the opportunity for eligible patients to benefit from targeted treatment

  • Reflex testing may decrease turnaround time and produce a faster initiation of appropriate treatment, and may find more patients with actionable mutations17
    • In a retrospective study, adoption of reflex testing significantly decreased turnaround time for molecular testing results from 52.6 to 15.6 days
    • A retrospective study found that standardized reflex testing led to higher mutation detection rates, with approximately twice as many mutations reported by reflex testing compared to non–reflex testing
  • Liquid biopsy (plasma) molecular testing has not been clinically validated in the resectable NSCLC setting18

Large, prospective studies are needed to establish clinical validity.

Based on a single-center, retrospective study of 220 patients with a newly diagnosed early or advanced lung adenocarcinoma whose specimens were received for molecular testing over a 3-year period between 2016 and 2018. Standard molecular testing performed on 39 patients in 2016 had an average turnaround time of 52.6 days, whereas reflex ordered molecular testing in 2017 yielded an average turnaround time of 26.5 days (n=127) and 15.6 days in 2018 (n=54). The average turnaround time for reporting of molecular results decreased by 37 days (P=0.0002) with adoption of reflex ordered testing.17

Based on a single-center, retrospective study of 220 patients with a newly diagnosed early or advanced lung adenocarcinoma whose specimens were received for molecular testing over a 3-year period between 2016 and 2018. Reflex testing group reported higher mutation detection rate compared to non-reflex testing group (48.8% vs 25.6%; P<0.05).17
