Anmerkungen

ISS (Greipp 2005) is the original 3-tier MM staging using β2M and albumin only. ISS-1 (β2M <3.5 + albumin ≥3.5) = median OS ~62 mo in the original cohort and substantially longer in the modern era with daratumumab-based 1L (PERSEUS / IsKia / GRIFFIN show D-VRd 4-yr PFS ~85% in ISS-1). de-escalate direction means "do not add cytogenetic- driven intensification beyond D-VRd baseline" — high-risk cytogenetics override this if present (handled by separate biomarker RFs).
