BIO-HNF1AHNF1A somatic mutation in hepatocellular carcinoma and hepatocellular adenoma (H-subtype); diagnostic/risk-stratification marker; no HNF1A-directed systemic therapyIIB
  • SRC-NCCN-HCC-2025: Level Category 2A (Supports, Sensitivity/Response)
  • SRC-AASLD-HCC-2023: Level B (Supports, Sensitivity/Response)
HNF1A somatic inactivating mutations occur in ~10% of HCC and ~35–40% of hepatocellular adenoma (H-subtype, H-HCA). Clinical utility: (1) HCA subtyping: biallelic HNF1A inactivation defines the H-HCA subtype characterized by steatotic hepatocytes, LFABP (liver fatty acid binding protein) loss by IHC, and very low malignant transformation risk (<1%). H-HCA management: surveillance rather than resection for lesions <5 cm in women who discontinue oral contraceptives; resection for >5 cm or persistent growth. (2) HCC context: somatic HNF1A mutation in HCC is associated with preserved hepatocyte differentiation phenotype (low AFP, well-differentiated histology) but does not select systemic therapy. Standard HCC management applies: lenvatinib or sorafenib 1L; atezolizumab + bevacizumab (IMbrave150) preferred 1L for Child-Pugh A patients without contraindications. (3) Germline HNF1A (MODY3): not an HCC risk factor; separate clinical context (diabetes management), not oncologically relevant in HCC. ESCAT IIB: HNF1A mutation is a validated diagnostic/risk-stratification marker for HCA subtyping with management implications; no therapeutic target in HCC.Atezolizumab 1200 mg + bevacizumab 15 mg/kg IV q3w — preferred 1L advanced HCC (Child-Pugh A, ECOG 0–1; IMbrave150 OS HR 0.66; not HNF1A-specific)
Lenvatinib 12 mg (≥60 kg) or 8 mg (<60 kg) PO QD — 1L alternative HCC (REFLECT; non-inferior to sorafenib; not HNF1A-specific)
Hepatic surveillance (MRI liver q6m) ± resection for H-HCA >5 cm or growth — HNF1A-inactivated HCA management (LFABP IHC surrogate; low malignant risk)

Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track
  • 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). RF-HCC-CHILD-PUGH-B-C
  • 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. RF-HCC-VARICEAL-BLEED

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