HCC in cirrhotic liver
The Tumor Marker
If You Read One Thing
AFP
Alpha-Fetoprotein >400 ng/mL = Diagnostic
Made by fetal liver cells before birth. Adults should not make it. When HCC grows, cancer cells flip the fetal program back on and dump AFP into the blood. Elevated AFP in an adult with a liver mass = HCC until proven otherwise. But sensitivity is low: a third of HCCs have normal AFP.
Cirrhotic liver→Fetal genes re-activate→AFP rises
The Hit List
Ten things that beat up a liver until it gives in. Tap each card to see how it lands the hit.
🦠
Hepatitis B
DNA virus
tap →
Inserts viral DNA directly into hepatocyte genome. Chronic inflammation + direct oncogene activation. Causes HCC even without cirrhosis: the only major risk factor that does. HBV + aflatoxin = synergistic risk.
🧫
Hepatitis C
RNA virus
tap →
Drives chronic inflammation for 20+ years → cirrhosis → HCC. Most common HCC cause in the US. Almost always needs cirrhosis as the middle step. Surveillance: ultrasound q6mo + AFP.
⬛
Cirrhosis
Final common path
tap →
Scarred liver = constant cell turnover + repair. Every division is a mutation chance. Cirrhosis is the soil HCC grows from. Child-Pugh score determines treatment eligibility.
🥫
Aflatoxin
Aspergillus toxin
tap →
Aspergillus flavus on moldy peanuts and grain. Mutates the p53 tumor suppressor in hepatocytes. Synergistic with HBV. Classic stem: peanut farmer + HCC.
🍷
Alcohol
Chronic toxin
tap →
Ethanol → acetaldehyde damages DNA. Decades of inflammation → alcoholic cirrhosis → HCC. Works through the cirrhosis pathway, not directly onto hepatocyte DNA.
🏗
NASH
Metabolic syndrome
tap →
Non-alcoholic steatohepatitis: fat + inflammation → fibrosis → cirrhosis → HCC. Fastest-growing HCC cause worldwide as obesity rates rise. No alcohol required.
🧀
Wilson's Disease
Copper overload
tap →
ATP7B mutation → copper cannot leave the liver → oxidative damage → cirrhosis → HCC. Look for Kayser-Fleischer rings in the eye.

Choose the Liver Lane
Commit before the reveal. The clue tells you whether the mass belongs to hepatocytes, vessels, or treatment staging.
A cirrhotic patient has a new arterial-enhancing liver nodule and AFP is markedly elevated. Which lane should you choose?
Right. Cirrhosis plus arterial blush plus AFP points to hepatocytes turning malignant, so the lane is HCC.
A PVC worker has a liver mass, normal AFP, and malignant cells lining vascular channels. Which lane should you choose?
Right. Vinyl chloride points to vessels, and normal AFP keeps HCC out.
A patient has one 4.5 cm HCC nodule, no vascular invasion, and no metastases. What lane opens?
Right. One nodule at or below 5 cm is within Milan criteria, so resection or transplant is on the table.
AFP highThink hepatocyte tumor: HCC in a cirrhotic or HBV-risk liver.
AFP normalWith vinyl chloride and vascular channels, think angiosarcoma instead.
Board Trap
Vinyl Chloride →Angiosarcoma
The most-tested distinction on the HCC risk list. Vinyl chloride absolutely damages the liver, but it grows a vascular tumor, not a hepatocyte tumor. Every other exposure (aflatoxin, alcohol, hepatitis, iron, copper) ends in HCC. If the stem says vinyl chloride or PVC factory, the answer is angiosarcoma. Period.
The One-Liner
Liver mass + AFP >400 = HCC.
Liver mass + vinyl chloride = angiosarcoma. 1 nodule ≤5 cm or 3 nodules ≤3 cm = Milan (resect/transplant). Beyond = sorafenib.
