Artificial Intelligence–Detected Tumor-Infiltrating Lymphocytes and Outcomes in Anti–PD-1–Based Treated Melanoma

In this cohort study, among patients with advanced melanoma, higher levels of AI-detected TILs on pretreatment hematoxylin-eosin slides were independently associated with improved ICI response and survival. Given the accessibility of TIL scoring on routine histology, TILs may serve as a biomarker for ICI outcomes. To facilitate broader validation, the Hover-NeXt architecture and model weights are publicly available.
