How is metastatic liver cancer diagnosed?

Metastatic liver cancer poses a severe health threat, significantly compromising hepatic function in numerous patients. Common symptoms include intense pain in the liver region, a sensation of fullness or discomfort, marked weight loss, and palpable upper abdominal masses. Once metastasis occurs, mortality rates rise substantially, causing considerable suffering to affected individuals.

How to Confirm Hepatic Metastasis

To confirm whether hepatocellular carcinoma (HCC) has metastasized, imaging studies are the first-line diagnostic approach.

First, for assessing intrahepatic metastasis, contrast-enhanced CT or contrast-enhanced MRI is recommended.

Second, to evaluate potential pulmonary metastasis, chest CT or plain chest radiography may be performed.

Third, for suspected bone metastasis, whole-body bone scintigraphy is advised.

Fourth, if financially feasible, whole-body PET-CT may be considered when clinically indicated; this modality can detect metastases with high sensitivity.

In summary, during the management of liver cancer, careful evaluation for distant metastasis is essential, and treatment strategies should be tailored according to the specific clinical scenario.

Imaging modalities—including ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI)—are non-invasive and may be repeated as needed based on clinical requirements. On ultrasound, metastatic lesions typically appear as hypoechoic or hyperechoic foci. On CT, they often present as heterogeneous or uniformly hypodense lesions, usually without associated cirrhotic changes. On MRI, metastases generally exhibit homogeneous signal intensity; occasionally, a “target sign” may be observed in individual cases.
