Origine du drapeau rouge
| Définition | t(11;14)(q13;q32) IGH/CCND1 translocation in multiple myeloma — ~15-20% prevalence, BCL-2-dependent / venetoclax-sensitive subset. Venetoclax-based regimens (BELLINI subgroup analysis: ven + bort + dex R/R MM mPFS 22.4 vs 11.6 mo in t(11;14) — vs no benefit in non-t(11;14)) drive R/R 2L+ selection. |

Notes
BELLINI overall trial showed OS detriment in non-t(11;14) — venetoclax in MM is biomarker-restricted to t(11;14) (and emerging high BCL2 expression, BCL2/BCL2L1 ratio). Off-label use only — venetoclax not formally MM-approved (CANOVA confirmatory phase 3 in t(11;14) R/R MM ongoing). Increased infection risk on venetoclax + DCEP / bort / dex — PJP + VZV prophylaxis. Detection: standard MM FISH panel (also covers high-risk t(4;14), t(14;16), del(17p), gain/amp 1q21 — covered by RF-MM-HIGH-RISK-CYTOGENETICS).
