These findings indicate that H3B-6527 enhances gastric cancer sensitivity to oxaliplatin by amplifying DNA damage and disrupting cell survival pathways. This study provides a rationale for clinical trials targeting FGFR4 in gastric cancer.

The FGF401/everolimus combination effectively suppressed tumor cell proliferation; promoted apoptosis; reduced tumor hypoxia via blood vessel normalization; and downregulated key proteins involved in proliferation, survival, metastasis, and angiogenesis. These preclinical findings provide a strong rationale for clinical trials combining FGFR4 and mTOR inhibitors in HCC patients with FGF19/FGFR4/mTOR-dependent tumors.

The authors were contacted by the Editorial Office to offer an explanation for these apparent anomalies in the presentation of the data in this paper; however, up to this time, no response from them has been forthcoming. Owing to the fact that the Editorial Office has been made aware of potential issues surrounding the scientific integrity of this paper, we are issuing an Expression of Concern to notify readers of this potential problem while the Editorial Office continues to investigate this matter further.  [Oncology Reports 30: 2777‑2784, 2013; DOI: 10.3892/or.2013.2796].

Phase I clinical trials of Irpagratinib (ABSK-011) demonstrated an objective response rate of 43.5%, which increased to 55.6% combined with atezolizumab. It also firstly synthesizes combination strategies and underlying mechanisms between FGFR4 inhibitors and targeted-immunotherapy, addressing critical gaps in existing reviews. Additionally, we discuss the potential of FGF19 as a predictive biomarker, integrating mechanistic and clinical evidence to advance precision HCC therapeutics.

Combination therapy using either lenvatinib or sorafenib and selective CAV1 inhibitors (e.g., siCAV1/miR-7), or AXL/FGFR4 inhibitors (e.g., BGB324/BLU9931) effectively overcame pan-TKI resistance. Our findings highlight a previously unrecognized role for CAV1-driven signalling in sustaining tumour dormancy, a critical and challenging therapeutic barrier underlying recurrence and pan-TKI resistance in HCC. Therapeutically targeting these pathways offer a promising and novel strategy to eliminate dormant tumour cells, thereby overcoming resistance and improving treatment outcomes.

These findings demonstrate that HNF1A drives PDAC metastasis via upregulation of FGFR4, and FGFR4 inhibition is a potential mechanism to target metastasis in PDAC patients.

The molecular makeup of tumors, including molecular subtype, tumor microenvironment composition, and gene mutations, fusions, and amplifications, has previously been correlated with a response to immune checkpoint inhibitors, erdafitinib, or enfortumab vedotin (EV) monotherapy, and may withhold potential candidate biomarkers. Stratification of patients into subgroups based on these molecular features is possible. Our data challenge the concept of a one-treatment-fits-all paradigm and support the rationale for prospective clinical trials with biomarker-guided treatment selection of mUC patients.
