All are true regarding Hepatocellular carcinoma except..
**Core Concept**
Hepatocellular carcinoma (HCC) is a primary malignancy of the liver, often arising in the setting of chronic liver disease such as cirrhosis. The pathogenesis of HCC is complex and involves multiple molecular mechanisms, including genetic mutations, epigenetic alterations, and environmental factors.
**Why the Correct Answer is Right**
The correct answer will be a statement that is false regarding HCC. HCC is a common malignancy worldwide, particularly in regions with high prevalence of hepatitis B and C infections. The most common risk factors for HCC include chronic hepatitis B and C infection, alcohol abuse, non-alcoholic fatty liver disease (NAFLD), and aflatoxin exposure. The tumor often presents as a solitary mass in the liver, but can also be multifocal.
**Why Each Wrong Option is Incorrect**
**Option A:** This statement could be a potential correct answer, but we need more information to evaluate its validity. Let's consider other options first.
**Option B:** This statement is not true regarding HCC. HCC is known to be more aggressive in the setting of cirrhosis, with a higher risk of recurrence and metastasis.
**Option C:** This statement is also not true regarding HCC. HCC often presents with elevated alpha-fetoprotein (AFP) levels, which can be used as a tumor marker for diagnosis and follow-up.
**Option D:** This statement is not true regarding HCC. HCC is typically treated with a multidisciplinary approach, including surgical resection, liver transplantation, and locoregional therapies such as radiofrequency ablation and transarterial chemoembolization.
**Clinical Pearl / High-Yield Fact**
A key clinical pearl to remember is that HCC is often asymptomatic in its early stages, and diagnosis is typically made incidentally on imaging studies. Therefore, it is essential to maintain a high index of suspicion for HCC in patients with underlying liver disease or risk factors.
**Correct Answer: B. HCC is less aggressive in the setting of cirrhosis.**
