PD-L1 negative

Although PFS benefits were observed in certain subgroups, these were accompanied by significantly increased treatment-related toxicities. Our findings suggest that no clear subgroup has been identified where the benefit outweighs the risks, necessitating extreme clinical caution.

However, these findings should be interpreted cautiously given the non-randomized design, baseline imbalances between groups, and the limited sample size of the CT alone cohort. Tolerability of CT + IO was consistent with that observed in clinical trials.

Benmelstobart plus anlotinib showed longer progression-free survival than pembrolizumab plus placebo and no unexpected safety signals were reported, suggesting benmelstobart plus anlotinib as a potential first-line option in driver gene-negative, PD-L1-positive, advanced NSCLC. Longer term follow-up is needed to establish effects on overall survival.

NRG1 fusions were identified in 0.8% of NSCLC, exceeding historical estimates and underscoring the importance of RNA-based NGS for fusion detection. The clinical and molecular profile mirrored prior reports, with predominant female patients, IMA histology, PD-L1 negativity, and low TMB. Outcomes were poor in metastatic patients lacking access to targeted therapy, supporting the need for broader implementation of RNA sequencing and access to anti-HER3 agents.

We hypothesize that the combination of these four therapeutic strategies could significantly enhance treatment efficacy in HER2-positive gastric cancer, particularly in combined positive score (CPS) PD-L1-negative patients. This study was registered at ClinicalTrials.gov (Identifier: NCT06385873).

High PD-L1 expression serves as an independent adverse prognostic biomarker in stage III but not stage II G/GEJC. These findings indicate a stage-dependent prognostic value of PD-L1 expression in G/GEJC.

Preliminary evidence suggests that T1 and T2 mapping can yield reproducible quantitative metrics, which may offer a means to non-invasively assess HER2 and PD-L1 expression in bladder cancer.

SN-MM displays an immune-desert phenotype yet retains intrinsic immunogenicity. Most tumors preserve functional IFN-γ signaling, while poorly differentiated cells show resistance to IFN-γ-mediated effects. These findings underscore heterogeneity in immune responsiveness and support functional immune profiling to refine immunotherapy strategies in MM.

This study confirms the promising efficacy and acceptable safety profile of AK104 combination therapy in patients with driver gene-negative advanced NSCLC. These findings collectively support the need for further large-scale prospective studies to validate its clinical utility.

In this study, no definitive prognostic or predictive role for PIK3CA alterations could be established. Nevertheless, these findings provide a descriptive real-world characterization of this molecular subset and support the need for validation in larger, prospectively designed, molecularly stratified studies.
