    Integration Analysis of Bayesian and Machine Learning for Heterogeneity, Biomarkers, and Optimal Combination Regimens of Pucotenlimab in Solid Tumors. (PubMed, Cancer Med)
    Network analysis recommended regimens: gemcitabine/cisplatin for TNBC (SUCRA = 95.7%), oxaliplatin/capecitabine for G/GEJ cancer (ORR = 60.0% vs. irinotecan 27.6%, HR = 0.45). The integrated model classified high-benefit (≥ 3 points; ORR 78.2%) and low-benefit (≤ 0 points; ORR 28.3%) groups, plus high-risk (≤ -2 points; grade ≥ 3 irAEs 41.2%) and low-risk (≥ 1 point; irAEs 3.5%) groups, validated by decision curve analysis. This defines precise application scenarios and provides an extensible analytical paradigm.
