Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track

Shimoyama acute or lymphoma subtype (LDH >2×ULN, BUN >ULN, albumin <ULN — any one) — aggressive variant; AZT+IFN-α inadequate, requires intensive chemo (mLSG-15) ± alloSCT.
Shimoyama's prognostic system is THE classifier in ATLL: smoldering/chronic-favorable get watch-and-wait or AZT+IFN-α; acute/lymphoma get aggressive chemo. Engine routes appropriately.
RF-ATLL-HIGH-RISK-BIOLOGYSRC-NCCN-BCELL-2025SRC-ESMO-PTCL-2024
Hypercalcemia (Ca >12 mg/dL) at diagnosis — hallmark of aggressive ATLL; requires bisphosphonate/calcitonin urgently and predicts aggressive subtype regardless of WBC.
Hypercalcemia in ATLL is paraneoplastic (RANKL-driven by HTLV-1+ T cells) — its presence overrides Shimoyama subtyping toward aggressive variant; AZT+IFN-α inadequate. Immediate hypercalcemia management + aggressive chemo (mLSG-15 /…
RF-ATLL-ORGAN-DYSFUNCTIONSRC-NCCN-BCELL-2025SRC-ESMO-PTCL-2024

CONTRA-AGGRESSIVE

Hard contraindications to escalation

Pre-treatment LVEF <50% is an absolute contraindication to anthracycline-containing regimens (R-CHOP, Pola-R-CHP, ABVD, BV-AVD, etc.). Cardiotoxicity from doxorubicin is dose-cumulative and often irreversible; starting with already-impaired function risks acute decompensation.CI-LVEF-LOW-FOR-ANTHRACYCLINE

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity

Aggressive plan (IND-ATLL-1L-AGGRESSIVE)

Do not give AZT+IFN for acute — wasted time, progression.
Do not skip mogamulizumab if available — overall survival benefit.
Do not give mogamulizumab before planned allo-SCT — pre-existing GVHD risk increased.
Do not neglect hypercalcemia treatment — bisphosphonates + hydration mandatory.
Do not give vincristine intrathecally — fatal.
Do not give full-dose anthracycline if LVEF <50%.

Standard plan (IND-ATLL-1L-INDOLENT-AZT-IFN)

Do not give AZT+IFN for acute / lymphoma type — poor response, delays chemo cycle.
Do not skip depression screening before IFN — IFN-induced depression is fatal (suicide risk).
Do not neglect hypercalcemia treatment — bisphosphonates + hydration.
Do not give IFN during pregnancy — teratogenic.
Do not skip TSH monitoring — IFN may induce thyroiditis.

MDT brief

Discussion questions (3, 1 blocking)

BLOCKING OQ-CD20-CONFIRMATION
Is CD20+ status confirmed by histology (IHC)? Without CD20+, rituximab/obinutuzumab are not indicated.
Anti-CD20 therapy is the backbone of most lines of treatment; absence of CD20 expression fully changes the regimen.
→ pathologist
OQ-STAGING-COMPLETE
Has complete staging been done (Lugano + PET/CT or CT)?
Prognosis and track selection depend on stage and tumor burden.
→ radiologist
OQ-LDH-CURRENT
What is the current LDH? Marker of tumor burden and transformation.
LDH is part of the prognostic indices of indolent lymphomas.
→ hematologist
