FGFR2 mutation

Unlike HCC, roughly 45% of iCCA harbor alterations amenable to precision oncology approaches, including fibroblast growth factor receptor 2 (FGFR2) fusions, isocitrate dehydrogenase 1 (IDH1) mutations, ERBB2 alterations, and BRAF mutations. In this review, we explore how this framework has reshaped liver cancer care and discuss the resulting breakthroughs in management and emerging directions that may further improve therapeutic strategies.

KRAS G12C-mutated NSCLC is clinically aggressive and frequently shows solid growth with rhabdoid, plasmacytoid, or SCC-like morphology, which may lead to misclassification and missed genetic testing. Immunohistochemistry and molecular profiling are essential for accurate classification and enabling targeted therapy.

Alpelisib plus fulvestrant provides clinical benefit for patients with PIK3CA-altered, HR+, HER2- ABC across a range of concomitant alterations, including those previously implicated in endocrine therapy or CDK4/6i resistance. Machine learning models identified factors including gene mutations that influenced PFS.

Fusion transcript analysis identified 91 recurrent fusions, including novel partners with ERBB2, MED1, and CDK12, suggesting the possibility of unique molecular events. Interpretation and conclusions This study demonstrates that Indian breast cancer patients exhibit molecular subtypes and actionable mutations comparable to Caucasian cohorts.

Stereotactic biopsy of diffuse brainstem tumors can be performed safely. Identification of targets for personalized therapy may be essential for management of these patients.

While approved pan-FGFR inhibitors provide clinical benefit, their durability is limited by acquired, often polyclonal, on-target resistance mutations affecting key regions of the FGFR2 kinase domain, including the gatekeeper residue (V565), molecular brake residues (N550, E566, K642), and other key variants...Given FGFR2-associated toxicities and the need for subtype selectivity, FGFR4 inhibition was prioritized as a selectivity determinant, while sparing FGFR1 was considered less critical. Guided by structure-based drug design, a reversible aminopyrimidine screening hit was optimized into a novel covalent inhibitor series active against FGFR2 wild-type and clinically relevant resistance mutations. An advanced lead 13 showed favorable potency, ADME properties, and demonstrated proof-of-concept in vivo efficacy in an FGFR2-amplified xenograft model comparable with the standard of care.

The integration of NGS and the subsequent use of matched targeted therapy significantly improved survival outcomes in selected patients with advanced BTC, highlighting the importance of precision medicine strategies.

Only one patient died 16 months after surgery due to an unrelated traffic accident.

A comprehensive literature search was performed in PubMed/MEDLINE, Embase, and Scopus for studies published from January 2000 to February 2026, using combinations of the terms 'cholangiocarcinoma,' 'FGFR2,' 'fibroblast growth factor receptor,' and 'futibatinib.' Relevant clinical trials, translational studies, and review articles were screened for inclusion. Futibatinib represents the most biologically rational FGFR inhibitor currently available for FGFR2-altered CCA, as it directly addresses the dominant mechanism limiting the efficacy of earlier agent, on-target resistance driven by secondary FGFR2 kinase domain mutations.

Pathological subtypes of CCA exhibit distinct clinical outcomes and molecular characteristics. Classification based on pathological subtype provides a useful framework for understanding the clinical and molecular heterogeneity of CCA.
