FGFR2 overexpression

FGFR2b expression exhibits substantial intratumoral heterogeneity in gastric cancer and may be linked to favorable outcomes in patients undergoing first-line ICI plus chemotherapy. Therefore, future studies should validate this finding, along with mechanistic investigations.

CLDN18.2 and FGFR2b were significantly associated with each other, suggesting a considerable overlap. This finding may have important clinical implications on the optimal treatment strategy for CLDN18.2-positive GC.

FGFR4 showed the strongest prognostic association among the FGFR family members studied, with high protein expression correlating with shorter disease-free survival in PDAC patients. These findings underscore the potential of FGFR4 as a biomarker for recurrence risk, while also highlighting the complexity of FGFR-related signaling and its context-dependent clinical relevance.

Our findings suggest a complex interplay between FGFR2 and RUNX2 in regulating tumor aggressiveness. This study underscores the significance of RUNX2 in luminal BrCa progression and posits RUNX2 as a promising therapeutic target and as a potential prognostic biomarker in luminal BrCa patients.

FDA approval of zolbetuximab's, an anti-CLDN18.2monoclonal antibody, is expected soon. Additionally, bemarituzumab, ananti-FGFR2b monoclonal antibody, has shown improvements in combination withchemotherapy in those with HER2 negative GAC with FGFR2 overexpression...Lastly, TROP-2 has emergedas an exciting solid tumor target and study is expected in GAC. All three ofthese therapeutic targets have seen an abundance of drug development in recentyears, and we anticipate newer targeted agents driving therapeutic decisions inGAC in the coming years.

we labeled FGF-2 with 99mTc and showed nanomolar Kd in vitro with human keratinocytes expressing FGF-2 receptors. In mice, 99mTc-FGF-2 rapidly and efficiently accumulated in tumors expressing FGF-2 receptors. This new radiopharmaceutical could be used in humans to image TAFs.

In conclusion, CAFs inhibited ferroptosis to decrease DDP sensitivity in NPC through secreting FGF5 and activating downstream FGFR2/Nrf2 signaling. The therapeutic strategy targeting FGF5/FGFR2 axis from CAFs might augment DDP sensitivity, thus decreasing the side effects of DDP in NPC treatment.
