Red flags — PRO / CONTRA aggressive
PRO-AGGRESSIVE
Triggers that push toward the aggressive track
- MF with large-cell transformation (LCT — ≥25% large cells on biopsy review) — aggressive variant; mandates systemic therapy reassessment, brentuximab vedotin if CD30+RF-MF-LARGE-CELL-TRANSFORMATION
- MF with B2 blood involvement (Sézary cell count ≥1000/μL OR ≥5% Sézary by morphology) — defines Sézary syndrome / IVA1 stage; routes to systemic therapy with mogamulizumab preferenceRF-MF-SEZARY-LEUKEMIC
- T-cell lymphoma with CD30 expression ≥10% by IHC — qualifies for brentuximab vedotin-based regimen (CHP-Bv per ECHELON-2)RF-TCELL-CD30-POSITIVE
CONTRA-AGGRESSIVE
Hard contraindications to escalation
- 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
Local therapy plan (IND-MF-EARLY-1L-SKIN-DIRECTED)
- Do not start systemic chemotherapy in IA-IIA — does not prolong OS, adds toxicity + loses options for progression.
- Do not skip Sezary count + TCR clonality in blood — occult B2 upstages, contraindicates skin-directed alone.
- Do not use NBUVB with photosensitivity (lupus, porphyria) — use topical alternatives.
- Do not forget about skin-cancer screening — MF + skin-directed elevates BCC/SCC risk lifelong.
- Do not interpret progression as failure — restage TNMB; change in T+N+M+B may give a different link to systemic therapy.
Standard plan (IND-MF-ADVANCED-1L-MOGA)
- Do not start mogamulizumab if allo-SCT is planned <50 days — severe GVHD risk per FDA black box.
- Do not ignore drug rash — interrupt + dermatology consult; differentiating from progression is critical.
- Do not combine with other immunosuppressants without dermatology + ID coordination — infection risk elevated.
- Do not use in the absence of MoH-import confirmation or clinical trial — not registered in Ukraine.
- Do not skip Sezary count baseline + repeat q3 mo — primary end point response in B-compartment.
Aggressive plan (IND-MF-ADVANCED-1L-BV)
- Do not prescribe without CD30 IHC ≥10% — ALCANZA inclusion criterion; lower expression = lower response.
- Do not use in pre-existing Grade ≥2 peripheral neuropathy — absolute CI.
- Do not combine with bleomycin (lethal pulmonary toxicity).
- Do not skip neuropathy grading every cycle — dose-cumulative MMAE toxicity.
- Do not use >16 cycles without response justification — risk vs benefit reverses.
Monitoring schedule
Monitoring schedule by treatment phase
Standard plan · MON-MF-SYSTEMIC
| Phase | Window | Tests | Checkpoints |
|---|
| baseline | Within 2 weeks before first dose | TEST-CBC, TEST-CMP, TEST-LFT, TEST-LDH, TEST-SEZARY-COUNT, TEST-TCR-CLONALITY, TEST-FLOW-CYTOMETRY, TEST-CD20-IHC, TEST-HBV-SEROLOGY, TEST-HCV-ANTIBODY, TEST-HIV-SEROLOGY, TEST-PET-CT | - Confirm TNMB stage; document T/N/M/B + IA-IVB stage
- Skin photograph baseline (mSWAT score) for response tracking
- If allo-SCT planned downstream — defer mogamulizumab (severe GVHD risk per FDA black box)
- Dermatology partnership for AE management (mogamulizumab rash ~25%)
|
| induction | Weekly × 5 doses (mogamulizumab) OR every 3 weeks (BV-mono) | TEST-CBC, TEST-CMP | - Infusion reactions (especially mogamulizumab first dose)
- Skin AE grading (CTCAE) — interrupt if severe rash; differentiate drug rash from disease progression
|
| maintenance | Every 2 weeks (mogamulizumab) OR every 3 weeks (BV-mono) until progression / toxicity | TEST-CBC, TEST-CMP, TEST-LFT | - mSWAT skin response every 2-3 months
- Sézary count repeat at 3 months (mogamulizumab — blood compartment response)
- Neuropathy grading on BV-mono
|
| response_assessment | After 12-16 weeks of therapy | TEST-PET-CT, TEST-SEZARY-COUNT | - Global response per ISCL/EORTC consensus (skin + nodes + viscera + blood)
- Continue if responding; switch line if stable/progressive
|
| follow_up | Every 3 months × 2 years post-treatment, then every 6 months | TEST-CBC, TEST-LFT, TEST-LDH, TEST-SEZARY-COUNT | - Surveillance for relapse + LCT
- Skin cancer screening (CTCL + treatment increases risk)

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
