Anmerkungen

ISS-3 (β2M ≥5.5) median OS ~29 mo in the original cohort, improved substantially in the daratumumab era. ISS-3 alone is not a sufficient intensification trigger — cytogenetics drive the upgrade to R-ISS (Palumbo 2015) and R2-ISS (D'Agostino 2022). When ISS-3 co-occurs with high-risk cytogenetics + LDH-high, R-ISS-3 emerges and warrants the most intensive 1L (RF-R-ISS-3-HIGH-RISK). Direction `intensify` reflects the four-drug-1L preference over triplet for ISS-3 even when cytogenetics standard.
