The Absolute Effect / Evidence
Chen et al. 2006 (PLAT vs resection)
Clinical question: What are the efficacy and safety outcomes of solitary hcc ≤5 cm?
Registry: No registry identifier reported · Prospective randomized trial; n=180. Evidence cut-off: 13 November 2026.
Design, eligibility and treatment
Solitary HCC ≤5 cm.
Percutaneous local ablative therapy versus partial hepatectomy.
Prospective randomized trial; n=180.
Overall survival and complications.
Key efficacy outcomes
4-y OS 67.9% PLAT vs 64.0% surgery; 1-, 2-, 3-y OS 95.8%, 82.1%, 71.4% vs 93.3%, 82.3%, 73.4%.
Safety
Complications more frequent/severe after surgery; one in-hospital death. Nineteen of 90 assigned PLAT withdrew consent before treatment.
Interpretation and limitations
Median survival differences and hazard ratios must not be converted into NNT. A patient pictogram is omitted unless a defensible fixed-time absolute event difference is reported.
Primary and supporting sources
Primary-source data reviewed; the page explicitly identifies unavailable full-text toxicity details rather than imputing them.
Current-practice context · 13 November 2026
Historical trial results are distinct from current treatment recommendations. Check current jurisdiction-specific guidance, liver function, biomarker requirements, local expertise and regulatory availability before applying these findings. Comprehensive guideline reconciliation and browser-rendered QA remain pending.
