Clinical Trial Summary
The goal of this multicenter retrospective cohort study is to investigate the clinical
outcomes and prognostic factors after hepatic resection in patients with HCC exhibiting PVTT,
and to develop a prognostic index that can be helpful in determining the treatment strategy.
Description:
Hepatocellular carcinoma (HCC) frequently invades the surrounding liver vasculature, with
portal vein tumor thrombosis (PVTT) being the most common form of macrovascular invasion. At
the time of HCC diagnosis, PVTT is detected in approximately 10%-40% of patients and is
associated with an extremely poor prognosis.
In most staging systems and guidelines, HCC with PVTT, regardless of the extent of the tumor,
is classified as an advanced stage, and surgical resection is not recommended as the
first-line treatment. Instead, consensus guidelines such as those from the American
Association of Study of Liver Disease(AASLD), the Asian Pacific Association for the Study of
Liver(APASL), and the European Association for the Study of Liver(EASL) recommend systemic
and targeted therapy for these patients. Despite these recommendations, experienced liver
centers in Asia have been attempting surgical resection for some patients with HCC exhibiting
PVTT, and the outcomes are favorable in selected patients. However, most of the studies were
conducted in only one center, had a small sample size, and obtained undesirable surgical
treatment outcomes in most of the patients. Thus, surgical resection has not yet been widely
accepted as an effective treatment for patients with HCC and PVTT. In addition, a prognostic
index that can indicate which surgical resection is beneficial in comparison with nonsurgical
treatment remains unestablished. A randomized controlled trial could be the best way to
compare the outcomes of surgical resection and nonsurgical treatments, but it is difficult to
conduct because of difficulties in ethical approval and allocation concealment. Therefore,
adequate studies with large sample sizes are needed to clarify the benefits of surgical
resection in patients with HCC and PVTT and the prognostic index, which can specify the
criteria for surgical resection in these patients.
This study aimed to investigate the clinical outcomes and prognostic factors after hepatic
resection in patients with HCC exhibiting PVTT, and to develop a prognostic index that can be
helpful in determining the treatment strategy.
