    Investigating the Retained Inhibitory Effect of Cobimetinib against p.P124L Mutated MEK1: A Combined Liquid Biopsy and in Silico Approach. (PubMed, Cancers (Basel))
    The samples at different time points were collected from a BRAF-mutant melanoma patient who developed an early resistance to dabrafenib/trametinib...With an in silico modeling, we identified cobimetinib as an alternative MEK inhibitor, and consequently suggested a therapy switch to vemurafenib/cobimetinib...The cobimetinib administration led to an important reduction in the BRAF p.V600E and MEK1 p.P124L allele fractions and in the CMC number, features suggestive of a putative response. In summary, this study emphasizes the usefulness of a liquid biopsy-based approach combined with in silico simulation, to track real-time tumor evolution while assessing the best treatment option.

    [VIRTUAL] The Association Between MAP2K1 Mutation Class and Clinical Features in MAP2K1‑Mutant East Asian Non‑Small Cell Lung Cancer Patients (IASLC-WCLC 2020)
    Briefly, patients with (n=9) or without (n=5) co-occurring TP53 mutations had a median OS of 12.0 months and not up to now respectively (P=0.41); patients with (n=3) or without (n=11) co-occurring KRAS mutations had a median OS of not up to now and 12.0 months respectively (P=0.33); patients with (n=4) or without (n=10) co-occurring KRAS mutations had a median OS of 14.5 months and 12.0 months respectively (P=0.57); patients with (n=4) or without (n=23) co-occurring STK11 mutations had a median OS of 11.5 months and 12.0 months respectively (P=0.70). Conclusion MAP2K1 genetic alter occurs in a subset of NSCLC, and improved understanding of the implications of MAP2K1 aberrations is critical for the identification of therapeutic target candidates.
