    Neoadjuvant retlirafusp alfa (anti-PD-L1/TGF-β bifunctional fusion protein) with or without chemotherapy in unresectable stage III non-small cell lung cancer: updated results from the phase 2 TRAILBLAZER trial. (PubMed, Signal Transduct Target Ther)
    Patients who underwent surgery after induction treatment achieved clinically meaningful survival gains. Our findings support the use of neoadjuvant immunotherapy with a response-adapted surgical strategy as a promising approach for unresectable stage III NSCLC.

    Optimal First-line Immune-related Therapy Selection for Advanced Gastric Cancer: A Systematic Review and Network Meta-analysis. (PubMed, J Gastrointest Cancer)
    Dual-target ICI-chemo appears to be the most effective first-line strategy for AGC based on current indirect evidence, surpassing single ICI-chemo and dual ICI-based regimens. These findings support personalized therapy selection but await confirmation by head‑to‑head trials. Future studies should address CPS < 1 and explore optimized combinations to enhance outcomes.

    Retlirafusp Alfa: First Approval. (PubMed, Drugs)
    In January 2026, retlirafusp alfa was approved for use in combination with fluorouracil and platinum-based drugs as a first-line treatment for locally advanced, unresectable, recurrent, or metastatic gastric cancer and gastroesophageal junction adenocarcinoma (GC/GEJA) with a PD-L1 positive CPS ≥ 1, as assessed by a well-validated assay in China. This article summarizes the milestones in the development of retlirafusp alfa leading to this first approval for the treatment of advanced PD-L1 positive GC/GEJA.
