The PAR dataset: Prostate biopsy whole slide images from an underrepresented Middle Eastern population

ABSTRACT: De-identified H&E whole-slide images (WSIs) of human prostate needle biopsies collected in Erbil, Iraq (mid-2013 to mid-2024). The cohort comprises 1,017 WSIs from 339 glass slides of185 patients (154 with two slides; 31 with one), each glass slide rescanned on three brightfield scanners (Grundium/SVS, Hamamatsu/NDPI, Leica/SVS) to enable cross-scanner benchmarking and robustness studies. Slides are fully anonymized and linked across rescans by a stable slide_id; no re-identification key exists. Slide-level Gleason and ISUP grades from three independent pathologists are provided: rater-1 graded all 339 slides, rater-2 graded 337, and rater-3 graded 59, supporting validation against human reference and weakly supervised training. This dataset, among the first high-quality WSI resources from an under-digitized setting like Iraq, aims to advance the development and evaluation of generalizable computational pathology models.
