Red Flag Origin
| Definition | History of prior topoisomerase-II inhibitor exposure — etoposide, teniposide, anthracyclines (doxorubicin, daunorubicin, epirubicin, idarubicin, mitoxantrone) — ≥1 year prior. Therapy-related AML following topoisomerase-II-inhibitor exposure has distinctive features that differ from alkylator-related t-AML: SHORTER median latency (2-3 years post-exposure vs 5-7y for alkylators), characteristic cytogenetics with balanced translocations involving 11q23 (KMT2A/MLL), 21q22 (RUNX1), or t(15;17) (PML-RARA, APL-like), absence of preceding MDS phase, lower TP53 mutation frequency. Higher per-dose risk than alkylators in some series. Highest risk: breast cancer survivors (anthracycline + cyclophosphamide), pediatric ALL/AML survivors (etoposide), testicular cancer survivors (etoposide in BEP). Prevention-persona RedFlag (§20 v0.3 iatrogenic pilot). |

Notes
Prevention-persona RedFlag for prior topoisomerase-II inhibitor exposure. Distinct from alkylator t-AML: shorter latency (2-3y vs 5-7y), characteristic 11q23/21q22 cytogenetics, often APL-like t(15;17). Engine routes to PreventionPlan recommending CBC q3mo for first 5y post-chemo + low threshold for marrow evaluation. STUB pending two-Clinical-Co-Lead signoff per CHARTER §6.1 dev-mode. Note: anthracycline exposure also fires RF-IATROGENIC-ANTHRACYCLINE-CARDIO-PREVENTION (separate cardio + t-AML surveillance overlap).
