Ibrutinib improves OS specifically in MCD/N1/A53 subtypes when added to R-CHOP (PHOENIX subgroup analysis, Wilson et al. Cancer Cell 2021).

Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track
  • Age-adjusted IPI ≥2 in patient <60 yo — high-risk young-adult DLBCL; supports DA-EPOCH-R consideration over R-CHOP per CALGB 50303 / Wilson and AYA-DLBCL seriesRF-AAIPI-HIGH
  • DLBCL with International Prognostic Index ≥2 — selects intensified Pola-R-CHP over R-CHOP per POLARIX evidenceRF-DLBCL-HIGH-IPI
  • High-risk biology in DLBCL NOS: double-expressor (MYC + BCL2 by IHC, no rearrangement), TP53 mutation, or non-GCB cell-of-origin in elderly / high-IPI context. Distinct from HGBL "double-hit" which is its own entity (DIS-HGBL-DH) — but double-expressor remains DLBCL NOS and shifts toward intensified backbone. RF-DLBCL-HIGH-RISK-BIOLOGY
  • DLBCL with International Prognostic Index 4-5 (high risk) — supports Pola-R-CHP intensification per POLARIX and triggers CNS-prophylaxis discussion via CNS-IPIRF-IPI-HIGH

CONTRA-AGGRESSIVE

Hard contraindications to escalation
  • Active or latent HBV without antiviral prophylaxis is an absolute contraindication to starting B-cell-depleting / immunomodulatory monoclonal antibody therapy (anti-CD20, anti-CD30 ADC, anti-CD38). Severe HBV reactivation hepatitis risk including fulminant hepatic failure.CI-HBV-NO-PROPHYLAXIS
  • 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
  • Severe pre-existing peripheral neuropathy is an absolute contraindication to bortezomib — therapy will likely worsen the neuropathy to a disabling and often permanent extent.CI-BORTEZOMIB-SEVERE-NEUROPATHY

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity
Standard plan (IND-DLBCL-1L-RCHOP)
  • Do not start without HBV screening + entecavir prophylaxis if HBsAg+ or anti-HBc+ — risk of fatal reactivation is significantly elevated on anti-CD20.
  • Do not prescribe without baseline LVEF ≥50% — anthracyclines are cardiotoxic; cardiomyopathy is often irreversible.
  • Do not ignore CNS-IPI — for patients with CNS-IPI ≥4 or high-risk anatomic sites (testicles, breasts, kidneys/adrenals, paranasal sinuses) add CNS prophylaxis (HD-MTX intercalated).
  • Do not skip the fertility preservation discussion in patients of reproductive age — cyclophosphamide causes azoospermia + amenorrhea.
  • Do not give vincristine intrathecally — FATAL. WHO/FDA require IV mini-bag packaging.
  • Do not escalate dose with febrile neutropenia without G-CSF — G-CSF prophylaxis for high-risk patients (age >65, prior cytopenia, advanced disease).
Aggressive plan (IND-DLBCL-1L-POLA-R-CHP)
  • Do not prescribe without a verified funding pathway — daratumumab... sorry, polatuzumab is not NSZU-reimbursed; the patient must be informed BEFORE being offered.
  • Do not start without HBV screening + entecavir prophylaxis if HBsAg+ or anti-HBc+ — anti-CD20 reactivation risk is not reduced by polatuzumab.
  • Do not prescribe without baseline LVEF ≥50% — anthracycline cardiotoxicity is the same as with R-CHOP.
  • Do not ignore pre-existing peripheral neuropathy — polatuzumab MMAE causes neuropathy; Grade ≥2 baseline = absolute CI.
  • Do not skip CNS prophylaxis if CNS-IPI ≥4 — same risk as with R-CHOP.
  • Do not use with concomitant strong CYP3A4 inhibitor without monitoring — increased neuropathy + myelosuppression.

Open 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.
