KRAS mutation

The targets evaluated have potential drugs currently under trial phase. This may help to define the subgroup for use of targeted therapy in NSCLC-SCC and in designing new treatment protocols.

We discuss this pathology, its treatment implications, as well as a brief literature review. This is the first case of metastatic colorectal cancer to the axilla in Australia and the only reported of such cases in literature with both MSI/MMR deficiency and KRAS146V mutation.

By integrating multi-omics data from clinical cohorts and validating findings in vivo, we show that combining KRAS inhibitors with CXCL9/10 restoration effectively overcomes this immune suppression and controls tumor growth. Our work delineates a targetable immune evasion mechanism and provides a cohesive prognostic and therapeutic framework for KRASG12/13-mutant CRC.

Those treated with PD-1/PD-L1 inhibitors (Pembrolizumab) had limited benefit, with a median overall survival of 4.1 ± 2.8 months...Comprehensive genomic profiling may help refine understanding of tumour biology and potentially inform treatment decisions. Larger studies are needed to validate these findings, but integrating genomic, pathologic, and clinical data may advance personalized therapy for these patients.

Patients with lung-only metastases had a better OS than others, were more often women, and harbored less KRAS mutations. Our results argue in favor of PDAC with specific characteristics, especially a better prognosis, possibly further enhanced by the possibility to perform local treatments, and less detection of ctDNA.

The triple combination of SHP2/MEK1/2 inhibition and the ferroptosis-inducing natural compound withaferin A suppressed tumor progression in an endogenous PDAC tumor model in vivo. Our study offers a metabolic leverage point to reinforce RAS pathway interference for targeted PDAC treatment.

Immunotherapy constitutes the cornerstone of first-line therapy for KRAS-mutant NSCLC. Within this framework, PD-(L)1 monotherapy may be appropriate for carefully selected patients with high PD-L1 expression, whereas chemoimmunotherapy can extend benefit to broader subgroups; escalation with anti-VEGF or anti-CTLA-4 agents appears clinically promising and merits biomarker-driven prospective evaluation. KRAS G12C inhibitors are effective in later lines, while treatment options for non-G12C disease remain limited.

BRAF-mut PTC is associated with a pro-inflammatory TME milieu compared to BRAF-wt PTC. However, in this limited data set, treatment choice was not associated with differences in OS in BRAF-mut PTC.

KRAS inhibitors, including KRAS G12D inhibitor MRTX1133, are promising therapeutics against KRAS-mutated pancreatic ductal adenocarcinoma (PDAC), but drug resistance limits their efficacy. Our study reveals that robust induction of apoptosis using a combination of BCL-xL PROTAC degrader and an mTOR inhibitor, significantly enhances MRTX1133 efficacy in PDAC models without increasing toxicity to normal tissues.
