OBJECTIVES:

Osimertinib is the third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that is approved for non-small cell lung cancer (NSCLC) patients with refractory to first or second-generation TKI and EGFR T790M mutation. Plasma and tissue re-biopsy are the most common method to detect T790M. However, the real-world effectiveness of osimertinib between plasma and tissue re-biopsy remain unclear. We aim to compare the clinical effectiveness between plasma and tissue re-biopsy.

METHODS:

We systematically searched on Pubmed, Embase and Cochrane library databases for studies that were published form January 2020 to December 2021. The terms we searched were “non-small cell lung cancer”, “osimertinib”, ”biopsy”. There were two authors independently to screen all studies, extract data and assess the risk of bias. The studies met following criteria were included: (1) advanced NSCLC, (2) the effectiveness of plasma and tissue re-biopsy after the first line EGFR-TKI treatment, (3) osimertinib as the second line EGFR-TKI treatment, (4) observation study. In meta-analysis, we applied pooled hazard ration (HR) and 95% confidence interval (95%CI) to compare the progression-free survival (PFS) and overall survival (OS) between plasma and tissue re-biopsy.

RESULTS:

Three articles with a total of 355 (tissue vs. liquid biopsy: 209 vs. 146) T790M mutation NSCLC patients receiving osimertinib were included in our study. The median PFS for tissue- and plasma-based detection of T790M mutation were 13.0 to 17.2 and 7.4 to 19.4 months, respectively. In pooled analysis, tissue biopsy was associated with better PFS compared to liquid biopsy (HR: 0.57, 95% CI: 0.35 – 0.92).

CONCLUSIONS:

Osimertinib as second-line treatment in non-small cell lung cancer patients detected T790M by tissue re-biopsy was associated with better clinical benefit than plasma re-biopsy.
