RAS wild-type

For OS, both cetuximab + chemotherapy [hazard ratio (HR)=0.853; 95% CI: 0.775-0.938; P=0.001] and panitumumab + chemotherapy (HR=0.855; 95% CI: 0.738-0.992; P=0.038) exhibited statistically significant superiority compared with bevacizumab + chemotherapy...In the present sensitivity analysis, UDP glucuronosyltransferase family 1 member A1-guided bevacizumab + 5-fluorouracil, leucovorin and irinotecan demonstrated favorable outcomes, with OS and PFS P-scores of 0.932 and 0.992, respectively; however, these findings were derived from a single trial with limited comparability...Treatment benefit from anti-EGFR therapy was markedly influenced by primary tumor location, with notable benefit observed in left-sided tumors and no benefit in right-sided tumors. These findings support tumor sidedness-guided treatment selection in clinical practice, favoring anti-EGFR-based therapy for left-sided and bevacizumab-based therapy for right-sided RAS wild-type mCRC.

Mouse embryonic fibroblasts transformed with KRASG12C also contain more saturated lipids than KRASG12D MEFs. Thus, activities of KRAS mutants depends on lipid acyl chain remodeling in an allele-specific manner.

The NTZ-AG regimen demonstrated meaningful anti-tumor activity and an acceptable safety profile as first-line therapy for unselected advanced pancreatic cancer patients, providing a rational basis for larger randomized controlled trials. This trial was registered at the Chinese Clinical Trial Register (ChiCTR) under the registration number ChiCTR2300072843 having URL https://www.chictr.org.cn/showprojEN.html?proj=198791.

Although recent advances have led to covalent inhibitors such as Sotorasib and Adagrasib for the KRAS G12C mutation, effective therapies for other common variants, particularly KRAS G12D, which is highly prevalent in aggressive pancreatic cancers, remain limited...To further validate the predictive capability of the models, two compounds identified as high-confidence candidates, Cobimetinib and Etrasimod, were selected for experimental evaluation...While additional biochemical and pathway-level studies are required to confirm direct target engagement, these results support the model's utility in prioritizing candidate compounds with allele-specific activity profiles. Overall, this study provides a data-driven framework for identifying potential KRAS-targeted therapies and highlights the value of integrating machine learning predictions with experimental validation.

Epidermal growth factor receptor (EGFR) blockade combined with cytotoxic chemotherapy has substantially improved outcomes in unresectable metastatic colorectal cancer (mCRC), particularly in patients with left-sided RAS wild-type disease [...].

Among cases with follow-up data (n=35), all 17 tumors with disease progression were DLL3 positive (13 RET-mutated tumors, 1 RAS-mutated tumor, and 3 RET/RAS wild-type tumors), including 5 with moderate expression and 12 with high expression. Most MTCs express DLL3; moreover, DLL3 expression is associated with lymph node metastases at diagnosis and disease progression, indicating that DLL3 may be an effective therapeutic target in MTC.

NF1 mutation is the strongest gene-level correlate of lung-selective metastasis in cutaneous melanoma. The NF1-mutant subtype may represent a dual-biomarker population and could warrant both pulmonary surveillance and prospective evaluation for immunotherapy.
