    Hallmarks of liver cancer: Therapeutic implications. (PubMed, Cell)
    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.

    The FGF-FGFR axis as an immune-metabolic rheostat in gastrointestinal inflammation and cancer. (PubMed, Front Immunol)
    Framing the FGF-FGFR network as an integrated rheostat offers a unifying mechanistic paradigm that links epithelial damage, metabolic dysregulation, and cancer development. It underscores the need for context-selective therapeutic interventions that reconcile tissue repair with long-term oncogenic risk.

    Malignant effusions serve as a feasible source for therapy-related biomarker testing in advanced gastric cancer. (PubMed, J Clin Pathol)
    Malignant effusion CBs show favourable intra-patient biomarker consistency over time, supporting their feasibility for longitudinal monitoring. Effusion-based testing shows potential value for potentially identifying candidates for FGFR2b-targeted therapies, pending further clinical validation.

    Calcified chondroid mesenchymal neoplasm: a case report of perineal involvement and literature review. (PubMed, Front Oncol)
    Existing literature primarily identifies such tumors in the distal extremities and temporomandibular joint; however, the case reported herein is the first documented occurrence in the perineum of a female. This finding suggests that the spectrum of CCMN may extend beyond the traditionally recognized locations of the distal extremities and temporomandibular joint.

    Case Report: Rare pheochromocytoma in a patient with Li-Fraumeni syndrome: a 3-event, 4-hit model of pathogenesis. (PubMed, Front Oncol)
    In contrast to the pheochromocytoma, the BDA showed no evidence of a second TP53 alteration that might suggest that TP53 had played a role in its pathogenesis. This case highlights the rare presentation of pheochromocytoma in LFS and provides a molecular hypothesis of how this tumor may have developed.

    Phase III trial of infigratinib versus gemcitabine/cisplatin in adults with advanced cholangiocarcinoma with FGFR2 gene fusion or rearrangement: results and reflections on early termination of PROOF 301. (PubMed, ESMO Open)
    Early termination limited the ability to draw definitive conclusions on the efficacy of infigratinib as first-line treatment of FGFR2-rearranged CCA. This study illustrates the challenges of powering confirmatory studies in biomarker-selected subpopulations of rare tumors and highlights the need for regulatory collaboration to develop pragmatic frameworks for assessing novel therapies in ultra-rare malignancies.
