Sorafenib is a well-known approved systemic therapeutic agent used in patients with advanced hepatocellular carcinoma (HCC). Regorafenib and nivolumab are approved as second-line therapeutic drugs in patients showing disease progression after sorafenib therapy. However, there is no established third- or fourth-line therapy in patients with progression after regorafenib or nivolumab treatment. Recently, the combination of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICPIs) has been attempted as a firstline treatment strategy in advanced HCC patients based on the hypothesis that combination therapy may overcome resistance in ICPI monotherapy. On the basis of this suggestion, we herein describe the case of an HCC patient demonstrating macrovascular invasion, whereby partial remission was achieved via the combination of sorafenib and nivolumab following disease progression after nivolumab therapy. Further studies on the combination of TKIs and ICPIs are necessary to determine ways to manage HCC patients showing disease progression after ICPI therapy.
Sorafenib is the only approved targeted agent as the first line systemic therapy for treatment of
advanced hepatocellular carcinoma (HCC). However, the improvement of survival duration under
3 months is far from clinical satisfactory and most patients experience disease progression within
6 months after sorafenib therapy. Unfortunately, second line systemic therapy after treatment
failure of sorafenib was not established and there were no clear guidelines for salvage treatment
modalities. Recently, studies suggests that combination of sorafenib and single cytotoxic agent
can be relatively effective and safe strategy that achieves promising rates of local and systemic
control in advanced HCC patients. Based on above suggestions, we herein offer our experience
of a case achieved complete remission by combination therapy of sorafenib and tegafur in the
patient with progressed disease after sorafenib therapy.
Hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) have a
extremely poor prognosis. According to the Barcelona Clinic Liver Cancer guideline, sorafenib
is a standard therapy in this situation, but many clinicians still select locoregional therapy (LRT)
such as transarterial therapy, external beam radiation therapy (EBRT), even surgical resection
(SR) or combination of LRTs because the survival improvement by sorafenib is unsatisfactory.
Based on recent meta-analysis and prospective study, transarterial chemoembolization (TACE)
and transarterial radioembolization seem to be effective and safe therapeutic option that
have comparable outcome to sorafenib. Recently large nationwide studies demonstrated
that SR can be a potentially curative treatment in selected patients. Hepatic arterial infusion
chemotherapy (HAIC) can be also good option, especially in Child class B patients based
on small volume prospective studies. Moreover, multidisciplinary strategies based on the
combination of LRTs (SR plus TACE, TACE + EBRT, TACE + Sorafenib, HAIC + EBRT etc.) may
improve survival of HCC patients with PVTT. Finally we discuss individualized and tailored
treatment strategies for different clinical situations.

Transarterial chemoembolization (TACE) is the worldwide procedure performed for patients
with various stage hepatoceullar carcinoma (HCC), but is not yet considered as curative
treatment because of relatively high local recurrence rate. Moreover, many clinicians
frequently experience treatment failure (incomplete necrosis or stage progression etc.) after
repeated TACE, but no clear guidelines have been recommended about salvage treatment
modalities for this situation. Recently, studies for combination of radiation therapy and TACE
for HCC with TACE refractoriness have been tried and reported better therapeutic efficacy.
Based on above suggestions, we herein offer our experience of a patient with macrovascular
invasion developed after repeated TACE that achieve complete remission by stereotactic
body radiation therapy. Further study, maybe regarding a combination of locoregional and
systemic therapy, is necessary on how to manage HCC patients with TACE refractoriness.
Reserved liver function is one of the most important determinants of survivial in advanced
hepatocellular carcinoma (HCC). Especially in cirrhotic patient with decompensated liver
function, sorafenib for HCC with main portal vein invasion have limited efficacy and survival
benefit. Therefore many clinicians or centers still try locoregional therapy (LRT) such as
transarterial chemoembolization (TACE), radiation therapy (RT), or combination with LRT
and sorafenib in this situation. However this multidisciplinary approach may increase
treatment related toxicity such as liver failure, etc. Recently, studies for combination of RT
and sorafenib for HCC with portal vein invasion have been tried and reported not only better
therapeutic efficacy, but also more hepatic toxicity.Based on above suggestions, we herein
offer our experience of a patient that although achieved survival gain via partial remission
of intrahepatic tumor and main portal vein thrombosis and metastatic lymph node by
combination therapy of RT and sorafenib, finally expired due to hepatictoxicity. Further study,
maybe regarding a combination of locoregional and systemic therapy, is necessary on how to
manage decompenstated cirrhotic patients with HCC with main portal vein invasion. (J Liver
