The next iteration—Sakitamiwa 4.0 (expected 2026)—aims to incorporate liquid biopsy biomarkers (circulating tumor DNA, exosomal microRNAs) and artificial intelligence-driven whole-slide image analysis. Preliminary data suggest that AI-enhanced Sakitamiwa grading achieves 94% concordance with expert consensus, compared to 78% for human-only grading. compared to 78% for human-only grading.
