A 52-year-old man from rural Maharashtra with a 10-year history of cirrhosis presents for HCC surveillance. Which tumor marker, when persistently elevated, is most commonly associated with poor prognosis and advanced HCC?

Explanation

## AFP Levels and HCC Prognosis **Key Point:** AFP level correlates with tumor burden and prognosis. AFP >1000 ng/mL indicates advanced HCC with poor prognosis and is associated with larger tumors, vascular invasion, and shorter survival. ### AFP Stratification in HCC: | AFP Level | Implication | Prognosis | |-----------|-------------|----------| | <20 ng/mL | Normal | Excellent | | 20–400 ng/mL | Intermediate risk | Variable | | >400 ng/mL | Diagnostic (in cirrhosis) | Poor | | >1000 ng/mL | Advanced disease | Very poor | ### Why AFP >1000 is Most Common Marker for Poor Prognosis: - Strongly associated with high tumor burden - Indicates aggressive tumor biology and vascular invasion - Most commonly used prognostic cutoff in clinical practice - Included in major staging systems (BCLC, AASLD) - Median survival <12 months when AFP >1000 ng/mL **Clinical Pearl:** In India, cirrhotic patients with AFP >1000 ng/mL often present with advanced BCLC stage C disease, requiring systemic therapy rather than curative options. **High-Yield:** AFP >1000 ng/mL is the most frequently cited prognostic cutoff and is associated with significantly reduced overall survival compared to lower levels.
