Real-World Predictors of Survival and Response in Advanced Melanoma
Immunotherapy has transformed advanced melanoma care, yet many patients fail first‑line treatment. Researchers applied machine‑learning to a large, real‑world electronic health record database to build interpretable models for overall survival, progression‑free survival, and response. ECOG performance status, PD‑L1‑based first‑line therapy, elevated LDH, and liver or brain metastases emerged as the strongest predictors. An interaction between high LDH and liver metastases identified a subgroup at the highest risk of death or progression.
