RF-HCC-VARICEAL-BLEED ★ winner: Active or recent (≤6 months) variceal hemorrhage in HCC patient with cirrhosis. Mandates EGD assessment + variceal band ligation BEFORE any bevacizumab-containing regimen (atezo+bev, IMbrave150 prerequisite). Active bleeding is an absolute hold on systemic therapy until controlled. SRC-NCCN-HCC-2025SRC-AASLD-HCC-2023

Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track

Patient with active or incompletely controlled pre-existing autoimmune or inflammatory disease (sarcoidosis, rheumatoid arthritis, IBD, SLE, autoimmune hepatitis, inflammatory myopathy, myasthenia gravis, or similar) is considered for immune checkpoint inhibitor (ICI) therapy — elevated risk of immune-related adverse events (irAE) flare or de-novo grade 3-4 irAE. Requires specialist (rheumatology / pulmonology / gastroenterology) pre-treatment review; prefer lower-irAE-burden backbone when options exist (pembrolizumab mono > ipilimumab+nivolumab).
Pre-existing autoimmune disease is present in ~10-15% of patients eligible for ICI therapy; historically excluded from pivotal trials. Real-world data (Abdel-Wahab 2018, 3557 pts) shows 55% experienced irAE flare and ~29% required…
RF-ACTIVE-AUTOIMMUNE-DISEASE-ICI-RISKSRC-SITC-ICI-IRAEMANAGEMENT-2021SRC-ESMO-ICI-TOXICITY-2022
Child-Pugh B or C cirrhosis in HCC patient. CP-A is the only fully- studied class for ICI combinations (atezo+bev, durva+treme); CP-B has partial sorafenib/lenvatinib data but worse safety; CP-C generally precludes systemic therapy (focus on supportive care + transplant evaluation if liver-limited disease).
Child-Pugh score assesses encephalopathy, ascites, bilirubin, albumin, INR. CP-B: ICI-bev contraindicated (anti-angiogenic stress on decompensated liver); sorafenib partial data (GIDEON registry). CP-C: best supportive care + hepatology /…
RF-HCC-CHILD-PUGH-B-CSRC-NCCN-HCC-2025SRC-AASLD-HCC-2023
Active or recent (≤6 months) variceal hemorrhage in HCC patient with cirrhosis. Mandates EGD assessment + variceal band ligation BEFORE any bevacizumab-containing regimen (atezo+bev, IMbrave150 prerequisite). Active bleeding is an absolute hold on systemic therapy until controlled.
IMbrave150 explicitly excluded patients with high-risk varices not treated by ligation/banding. Routes patient to durva+treme (STRIDE) alternative (HIMALAYA — no bev exposure) OR to TKI (sorafenib / lenvatinib) alone if anti-angiogenic…

CONTRA-AGGRESSIVE

Hard contraindications to escalation

Pembrolizumab (and other PD-1/PD-L1 inhibitors) augment T-cell responses; in patients with active autoimmunity or post-transplant immunosuppression, this can precipitate severe organ-specific flares (colitis, hepatitis, pneumonitis, transplant rejection) that may be fatal or require transplant loss. CI-PEMBROLIZUMAB-AUTOIMMUNE

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity

Aggressive plan (IND-HCC-SYSTEMIC-1L-DURVA-TREME)

Do NOT use in Child-Pugh B/C
Do NOT skip HBV prophylaxis
Do NOT continue through Grade 3+ irAE without permanent discontinuation consideration (CTLA-4 colitis can be fatal)

Standard plan (IND-HCC-SYSTEMIC-1L-ATEZO-BEV)

Do NOT initiate without EGD within 6 months — high-risk varices must be ligated/banded first (perforation/bleed risk)
Do NOT use in Child-Pugh B/C — atezo+bev not studied; mortality risk
Do NOT skip HBV prophylaxis in HBsAg+ / anti-HBc+ patients (entecavir or TDF) — HBV reactivation reported under anti-VEGF + ICI; continue ≥12 mo post-therapy
Do NOT delay HCV-DAA in HCV-RNA+ patients — initiate sofosbuvir/velpatasvir before or concurrently with atezo+bev; SVR12 reduces decompensation risk and may improve OS in HCC-on-HCV-cirrhosis
Do NOT combine sofosbuvir with amiodarone — severe bradycardia / cardiac arrest
Do NOT continue bevacizumab through Grade 3+ HTN or proteinuria >3.5 g/24h

Standard plan (IND-HCC-SYSTEMIC-1L-SORAFENIB)

Do NOT continue through hepatic decompensation onset
Do NOT delay HFSR prophylaxis (urea cream, emollient, friction avoidance)
