NRAS wild-type

This meta-analysis shows that KRAS, NRAS, and BRAF mutations are important for adverse prognostic markers in colorectal cancer, linked to reduced overall survival. Routine molecular testing for these mutations is vital to enable personalized treatment, improve patient stratification, and enhance clinical outcomes in colorectal cancer management.

Furthermore, both inhibitor classes show similar cellular efficacy in the presence of growth factors that drive KRAS, wt NRAS, and wt HRAS to the active state. These data provide the first detailed account of targeting both the active and inactive states of KRAS G12C and highlight the absence of a mechanistic advantage in contexts dependent on prolonged target inhibition.

Within surgically treated patients, baseline CA19-9 emerged as the most informative prognostic marker, while traditional clinicopathologic variables showed limited discriminatory value. These findings highlight the importance of careful patient selection and support further prospective studies integrating molecular and biomarker-based strategies to refine prognostication and optimize surgical decision-making in RAS-WT mCRC.

Here, we show that combined treatment with a RAS/PI3K/AKT-pathway inhibitor rigosertib (RGS), and/or a MEK1/2 inhibitor trametinib (T), plus aCD40, overcomes the ICB resistance of BRAFwtNRASwt and BRAFwtNRASmut melanoma tumors growing in C57BL/6 mice. scRNA-Seq analyses confirm CD40-associated CD11b+ Bregs across cancer types in patients. Our data demonstrate that addition of RAS/PI3K/AKT and MEK inhibitors to aCD40 resolves the issue of aCD40 induction of CD11b+PD-L1+ Bregs and provides alternative therapeutic options for ICB-resistant BRAFwtNRASwt or BRAFwtNRASmut metastatic melanoma.

This is the largest national dataset on melanoma NRAS and KIT status published to date. Variations in NRAS/KIT testing by geographic/demographic factors drives initiatives to ensure consistent care. NRAS mutated melanoma had high incidence which emphasises the unmet need to develop therapies and trials for NRAS mutated melanoma. This study increases our understanding of biomarkers NRAS and KIT and provides a foundation for optimising melanoma care, contributing to advancements in precision oncology.
