Narrative

Aleksandar is in the elevated-risk band — F2 fibrosis from chronic HCV. Modern DAA therapy achieves SVR12 (cure) in >97%. Critical insight: SVR ≠ HCC immunity — fibrotic livers retain residual HCC risk for life and require continued biannual surveillance even after viral cure.

EvidenceAASLD/IDSA 2023 + Backx 2021 meta-analysis (n=43,000) — DAA-cured HCV with F2 fibrosis approaches general-population mortality WITH continued HCC surveillance. SVR halves all-cause mortality, but residual HCC risk persists for life in F2+ patients.
How to actually realise the gain

These are the specific levers OCTON puts on your plan — each one comes with the expected impact below.

drug
Sofosbuvir/Velpatasvir 400/100 mg daily × 12 wk
SVR12 cure in >97% (pan-genotypic)
scan
Lifelong biannual liver US + AFP (HCC surveillance)
Catches HCC at curable size; non-negotiable in F2+
scan
Annual FibroScan + LFTs
Tracks fibrosis regression post-cure
diet
Mediterranean + low ultra-processed + coffee 2-3 cups/day
Coffee independently ↓ HCC risk (meta-analysis)
lifestyle
Alcohol abstinence + Hep A/B vaccination
Prevents accelerated hepatic injury post-cure
exercise
150 min/wk moderate cardio + resistance 2×/wk
Prevents NAFLD overlay; metabolic resilience

OCTON Impression · 81% confidence

Liver stiffness 8.4 kPa (METAVIR F2, significant fibrosis). CAP 232 dB/m (S1 mild steatosis). HCV RNA 1.2 × 10⁶ IU/mL, genotype 1a. Pre-treatment APRI 1.4, FIB-4 2.6 — both correlate with FibroScan F2.

Findings
  • Liver stiffness 8.4 kPa (F2) · Right liver lobe
  • CAP 232 dB/m (S1 mild steatosis) · Right liver lobe
  • Spleen normal · no portal HTN · Spleen
Differential diagnosis
  • Chronic HCV with F2 fibrosis88%
  • HCV + concurrent NAFLD contribution8%
  • Drug-induced hepatitis3%
  • Autoimmune component (negative ANA, ASMA)1%
Recommended actions
  • ▸Initiate DAA: sofosbuvir/velpatasvir 400/100 mg daily × 12 weeks (pan-genotypic, no cirrhosis dose adjustment)
  • ▸HCV RNA at week 4 + week 12 + SVR12 (12 weeks post-completion)
  • ▸Hepatology referral · HCC surveillance: ultrasound + AFP every 6 months (lifetime, even post-cure with F2+)
  • ▸Counsel partner re: screening; cascade testing for household contacts
Caveats
  • DAA cure does NOT remove residual HCC risk in F2+ — biannual surveillance is for life.
  • Genotype 1a may have NS3 RAS prevalence — pan-genotypic SOF/VEL covers all genotypes.

What changed

The early-detection win

Aleksandar's universal-cohort screen flipped his life. He thought a 1986 transfusion was old news; OCTON ran a single ELISA + RNA confirmation as part of his cubicle visit. Sofosbuvir/velpatasvir cured him in 12 weeks — but the more important catch was the F2 fibrosis. Post-cure, the system didn't 'discharge' him — it opened a lifetime biannual HCC surveillance lane. Five years later, SVR sustained, FibroScan dropped to F1, no HCC detected. The liver is the literal bridge between infectious diseases and oncology — OCTON treats it that way.
