Red flags — PRO / CONTRA aggressive
PRO-AGGRESSIVE
Triggers that push toward the aggressive track
- Histologic evidence of transformation to aggressive large B-cell lymphoma (DLBCL) on biopsy or suspected by rapid clinical progression / LDH elevation / PET hotspotRF-AGGRESSIVE-HISTOLOGY-TRANSFORMATION
- Frailty (ECOG ≥3 OR age ≥75 + ≥2 comorbidities) — DA-EPOCH-R infusional toxicity poorly tolerated; R-CHOP+RT preferred for fragile elderly.RF-PMBCL-FRAILTY-AGE
CONTRA-AGGRESSIVE
Hard contraindications to escalation
What NOT to do
Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity
Standard plan (IND-PMBCL-2L-RICE-AUTOSCT)
- Do NOT initiate without HBV screening + prophylaxis if HBsAg+ or anti-HBc+.
- Do NOT use ifosfamide with baseline encephalopathy or CNS metastasis without MRI clearance.
- Do NOT skip mesna prophylaxis (ifosfamide hemorrhagic cystitis).
- Do NOT prescribe in transplant-ineligible — switch to pembrolizumab or bispecific antibody.
- Do NOT forget GCSF prophylaxis — intensive myelosuppression with R-ICE.
- Do NOT delay response assessment — PET after 2 cycles is mandatory before autoSCT decision.
Monitoring schedule
Monitoring schedule by treatment phase
Standard plan · MON-RITUXIMAB-MONO
| Phase | Window | Tests | Checkpoints |
|---|
| baseline | Within 2 weeks before first dose | TEST-CBC, TEST-LFT, TEST-LDH, TEST-CD20-IHC, TEST-HBV-SEROLOGY, TEST-HCV-ANTIBODY, TEST-FLOW-CYTOMETRY | - Confirm CD20+ histology
- HBV status + entecavir prophylaxis if HBsAg+ or anti-HBc+
|
| induction | Day 1 of each weekly induction × 4 | TEST-CBC, TEST-LFT | - Infusion reactions especially first dose
|
| maintenance | Every 2 months × 2 years | TEST-CBC, TEST-LFT, TEST-LDH | - HBV-DNA quarterly during therapy and 12 mo post
- Disease assessment clinically; imaging if concern
|
| follow_up | Every 6 months × 5 years post-treatment | TEST-CBC, TEST-LFT, TEST-LDH | - Surveillance for relapse + transformation

Standard plan
Baseline
Within 2 weeks before first dose
Induction · R-ICE salvage with autoSCT consolidation (relapsed/refractory PMBCL)
14-day cycles × 2-3 cycles → restage → autoSCT if chemosensitive
Maintenance

Follow-up
Every 6 months × 5 years post-treatment
MDT brief
Discussion questions (2, 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
