Clinical significance of mutations (ESCAT)
Tumor-board context — the engine does not use these tiers to rank tracks
| Biomarker | Variant | ESCAT | Evidence | Clinical significance | Drugs | Sources |
|---|
| BIO-JAK3 | JAK3 activating mutation — mycosis fungoides (MF) or Sézary syndrome (SS); JAK/STAT pathway hyperactivation; ruxolitinib approved for MF/SS regardless of JAK3 status | IIA | - SRC-ESMO-CTCL-2024: Level B (Supports, Sensitivity/Response)
| Ruxolitinib cream (Opzelura) received FDA approval (September 2022) for mild-to-moderate atopic dermatitis; separately, ruxolitinib phosphate (Jakafi, oral) is FDA-approved for steroid-refractory acute/chronic GVHD but NOT specifically approved for CTCL as of 2026. However, the JAK/STAT pathway is aberrantly activated in MF/SS (~30–50% have JAK3 mutations or JAK1/STAT3/STAT5 alterations), making JAK inhibitors an active investigational area. Phase II evidence: ruxolitinib (oral) ORR ~29% in relapsed/refractory MF (RUXO-MF pilot data); itacitinib (JAK1 inhibitor) and cerdulatinib (JAK/SYK inhibitor) in phase II trials for CTCL. The CTCL-specific approvals are for non-JAK-targeted agents: romidepsin (HDAC inhibitor; FDA 2009 CTCL), brentuximab vedotin (CD30+; FDA 2017), mogamulizumab (CCR4; FDA 2018), vorinostat (FDA 2006). JAK3-mutant CTCL: JAK3 mutation identifies a subset with stronger a priori rationale for JAK inhibitor use; ESCAT IIA reflects absence of dedicated FDA approval in CTCL despite biological rationale and early phase data. | ruxolitinib 20 mg PO BID — investigational for JAK3/JAK1-altered MF/SS; no approved CTCL indication for oral ruxolitinib mogamulizumab 1 mg/kg IV weekly ×4 then q2w — FDA-approved for relapsed/refractory MF/SS (CCR4-targeted; JAK3-independent) brentuximab vedotin 1.8 mg/kg IV q3w — FDA-approved for CD30+ MF (CD30 ≥10% by IHC; JAK3-independent) | |

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
Standard 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.

- 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)

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.
→ hematologist
