| KIT mutation in mucosal / acral / chronic-sun-damaged melanoma (~15-20% of these subtypes; rare in cutaneous CSD-low): imatinib has activity (Carvajal JCO 2013; Hodi JCO 2013 — ORR 16-23% in selected KIT-mutant melanoma). Exon 11 L576P and exon 13 K642E are the most imatinib-responsive variants. Modern frontline is immunotherapy (anti-PD-1 ± anti-CTLA-4); imatinib is reserved for IO-refractory or IO-ineligible KIT-mutant disease. | imatinib (off-label / NCCN-supported for IO-refractory KIT-mutant melanoma exon 11 L576P / exon 13 K642E)

Why this branch was chosen
Triggers from the patient profile that fired and drove the chosen branch.
Step 1 → branch IND-MELANOMA-2L-KIT-IMATINIB
- RF-MELANOMA-KIT-MUT-ACTIONABLE ★ winner: KIT activating mutation (exon 11 / 13) in mucosal or acral melanoma subtype — ~15-20% prevalence in those subtypes (rare in cutaneous). Imatinib (Carvajal 2013 — ORR 23% in KIT-mut mucosal/acral) and nilotinib are off-label active; integrate with standard IO if eligible.

What NOT to do
Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity
Standard plan (IND-MELANOMA-2L-KIT-IMATINIB)
- Do not prescribe in KIT amplification without point mutation — non-predictive (Carvajal 2011).
- Do not prescribe in non-mucosal/non-acral melanoma without NGS-documented KIT mutation — low pre-test probability + false-positives.
- Do not continue >12 weeks without objective response (PR/CR) — early switch to ICI or BRAFi+MEKi if BRAF-co-mutated.
- Do not forget off-label justification for MDT — imatinib is licensed for CML/GIST/Ph+ALL, not melanoma.
- Do not ignore baseline + monthly LFTs — hepatotoxicity is a defined AE.
- Do not give with warfarin without monitoring INR — CYP3A4 substrate interaction.
Standard plan (IND-MELANOMA-2L-POST-IO-BRAFI-MEKI)
- Do not prescribe without verified BRAF V600E or V600K — non-V600 BRAF alterations do not respond to BRAFi+MEKi doublet.
- Do not ignore baseline + serial ECHO (LVEF) — binimetinib cardiomyopathy ~7%, mandatory monitoring q2-3 mo.
- Do not skip baseline + symptom-driven ophthalmology — RPED, RVO, uveitis class effect MEKi.
- Do not use in BRAF-WT — toxic, ineffective; pseudo-paradoxical activation of MAPK in BRAF-WT cells.
- Do not forget dermatology q3 mo — new SCC + primary melanomas class effect BRAFi (although less than vemurafenib mono).
- Do not prescribe in IO-naive (without 1L anti-PD-1) — DREAMseq showed that IO-first sequence is superior to targeted-first for OS.
- Do not confirm plan without verified funding pathway — ENCO+BINI out-of-pocket in Ukraine.
Aggressive plan (IND-MELANOMA-2L-POST-BRAFI-IPI-NIVO)
- Do not prescribe in baseline active autoimmune disease on systemic immunosuppression — irAE can be fatal (myocarditis, hepatitis).
- Do not ignore baseline TFTs, cortisol, LFTs, troponin — irAE monitoring is foundational.
- Do not give >10 mg/day prednisolone before start — reduces ICI efficacy.
- Do not continue ipi+nivo with Grade ≥3 irAE — switch to nivo maintenance or stop.
- Do not prescribe in pre-BRAFi setting in BRAF V600+ — DREAMseq showed that IO-first gives better OS in BRAF-mut patients (exception: visceral crisis requires BRAFi for rapid response).
- Do not give live vaccines during or for 3 months after completion.
Standard plan (IND-MELANOMA-2L-RELATLIMAB-NIVOLUMAB)
- Do not prescribe if the patient already received anti-PD-1 1L — this buys nothing new beyond additional LAG-3 blockade with minimal benefit post-PD-1.
- Do not ignore baseline troponin + ECG — myocarditis ~1.7% (higher than nivo mono); serial monitoring with symptoms.
- Do not give >10 mg/day prednisolone before start — reduces ICI efficacy.
- Do not use in baseline active autoimmune disease on systemic immunosuppression — irAE risk.
- Do not confirm plan without verified funding pathway — relatlimab not registered in Ukraine; pathway = named-patient import.
- Do not give live vaccines during or for 3 months after.
Aggressive plan (IND-MELANOMA-3L-LIFILEUCEL)
- Do not prescribe without verified spec center authorization — Iovance authorized treatment center or EU pilot site (Ukraine has no internal capability).
- Do not give systemic corticosteroids (>10 mg/day prednisolone) before or immediately after TIL infusion — abrogates TIL function.
- Do not prescribe with ECOG ≥2, LVEF <45%, FEV1 <60%, DLCO <60% — IL-2 contraindications, treatment-related mortality unacceptably high.
- Do not skip baseline brain MRI — untreated CNS mets exclusion.
- Do not perform at a center without ICU access + experience in IL-2 management — capillary leak syndrome can be fatal.
- Do not ignore antimicrobial prophylaxis (PCP, HSV, fungal) during prolonged neutropenia post-cy/flu.
- Do not confirm plan without funding pathway (~USD 500-700K all-in) + travel/lodging + 6-week absence from home.

What is the status of BRAF V600E mutation (BIO-BRAF-V600E)? It is required by track(s): IND-MELANOMA-2L-POST-IO-BRAFI-MEKI. Expected value: V600E or V600K positive (encorafenib + binimetinib labelled for both; dabrafenib + trametinib also active).
A treatment-track biomarker requirement is missing from the patient profile; the MDT should verify the test result, method, specimen, and date before relying on this option.
