Eligibility Criteria

19 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Age above 18 years
  2. HCC suitable for partial hepatectomy
  3. Child-Pugh A or B cirrhosis
  4. Eastern Cooperative Oncology Group performance score 0 or 1
  5. Barcelona clinic liver cancer (BCLC) staging A or B

  2. Evidence of tumor invasion of portal vein or hepatic vein
  3. History of acute tumor rupture presenting with hemo-peritoneum

Outcomes

Primary Outcome Measures

arterial flow through the tumor
Digital subtraction angiography (DSA) is performed before and after embolization, through catheterization of the arterial branches supplying the tumor, images from arterial phase to delayed phase are captured. Contrast distribution at the arterial tumor branches, arterioles, tumor sinusoids, peri-tumoral liver, and peri-tumoral portal venules are observed.

Secondary Outcome Measures

The degree of tumor necrosis
The percentage of viable residual HCC is assessed quantitatively in increments of 5 %, with the measurement of the largest axial diameter of viable HCC compared to that of the whole tumor using a microscopic ruler.

5. Study Description

Brief Summary
Hepatocellular carcinoma (HCC) is one of the commonest solid malignancies in Hong Kong as well as globally. Transarterial therapy has been playing an important role in the treatment algorithm for patients with HCC. The primary purpose of transarterial therapy is eradication of the viability of the targeted tumors. The treatment outcomes have been variable among the various treatments, in general, there is still much room for improvement, especially for large size tumors. From the studies on Transarterial chemoembolization (TACE), it is known that the treatment outcome is affected by the nature and the formulation of therapeutic agents that are delivered, which is related to the angioarchitecture of the tumor. Knowledge on the angioarchitecture of HCC is essential for the understanding of the requirements for effective transarterial treatment of HCC. This prospective study is aimed to study the angioarchitecture of HCC.
Detailed Description
Embolization is performed within 2 weeks before the scheduled date of partial hepatectomy. The purpose of the timing is two folded, it allows observation of the embolization effect to be differentiated among the various embolic agents, it also allows time for the patient and the liver to recover from the embolization. The patient then receives partial hepatectomy within 2 weeks unless the result of liver function tests shows contraindication to surgery, in which case the liver function test is further evaluated on a weekly basis until the findings are acceptable, and surgery is scheduled accordingly.

Intervention Name(s)
embolization
Intervention Description
Patient with a diagnosis of HCC and a treatment plan to receive partial hepatectomy will receive transarterial embolization under local anesthesia 2 weeks before the surgery. Angiographic examinations of the tumor before and after embolization of the tumor will be performed. Histological examination of the tumor in the surgical specimens will be performed.
