CNLC Staging (China)

The CNLC staging system (Guidelines for Diagnosis and Treatment of Primary Liver Cancer in China) generally recommends more aggressive interventions than BCLC for intermediate and advanced stages, reflecting differences in etiology (HBV) and surgical practice in China.

Evidence-based context for fast calculator use

Purpose:
CNLC staging classifies hepatocellular carcinoma by tumor extent, liver function, and performance status to guide resection, TACE, or systemic therapy.
Population:
patients undergoing liver-function, hepatocellular carcinoma staging, imaging, or transplant assessment
Factors:
General Status, Tumor Characteristics

When To Use

  • Use CNLC Staging (China) when cNLC staging classifies hepatocellular carcinoma by tumor extent, liver function, and performance status to guide resection, TACE, or systemic therapy.
  • Confirm that the patient, diagnosis, disease phase, and available inputs match the cited model before calculation.

How To Interpret

  • Interpret the displayed result using the calculator-specific formula and reference table, spanning Ia through IV.
  • A boundary result should prompt input verification and clinical review rather than false precision.

What To Do Next

  • Integrate liver reserve, portal hypertension, tumor burden, vascular invasion, extrahepatic disease, performance status, and transplant policy.
  • Document the inputs, result, timing, and clinical context so the assessment can be reproduced.

Limitations

  • Liver function, HCC stage, imaging category, and transplant criteria are complementary but not interchangeable.
  • The result supports clinician judgment and does not independently determine treatment.

Validated Population
