    Longitudinal minimally invasive monitoring of resistance mutations in ALK rearranged lung cancer patients (AACR 2022)
    ALK rearrangements are detected in approximately 4% of patients with advanced non-small cell lung cancer (NSCLC), and the tyrosine kinase inhibitors (TKIs) crizotinib, alectinib, brigatinib, ceritinib, and lorlatinib have been approved by the FDA for the treatment of ALK-positive NSCLC. The dPCR method was highly sensitive in detecting gene mutations with low allele frequency. It was also found to be able to monitor variable resistance mutations over time during ALK-TKI treatment. In addition, we found that the appearance of G1202R did not always indicate clinical acquisition of resistance that required drug modification.

    [VIRTUAL] Patient-derived lung cancer organoids for the selection of therapeutic options in an ALK-rearranged tumor. (ASCO 2021)
    One patient was deemed as sensitive to carboplatin but tumor showed to be resistant...The patient started alectinib but showed progression after 12 months...Treatment was switched to brigatinib with no response...The In vitro results demonstrated no activity of lorlatinib but a strong response to crizotinib... We present clinical evidence that PDOs are an alternative tool in oncogenic addicted tumors helping to guide treatment decisions and increasing a more personalized sequential treatment approach.

    BRAF V600E mutation as a novel mechanism of acquired resistance to ALK inhibition in ALK-rearranged lung adenocarcinoma: A case report. (PubMed, Medicine (Baltimore))
    We present a case of ALK-rearranged lung adenocarcinoma with acquired resistance to ALK inhibition, in which the BRAF V600E mutation is a novel resistance mechanism. This provides evidence that BRAF V600E mutation is one mechanism of ALK-TKI resistance.
