However, the drug shows limited efficacy: one trial reported median survival of only 6.5 months in HCC patients with PVTT on the drug <a class="elsevierStyleCrossRef" href="#bib0006">[6]</a>. This, coupled with the drug's high price, leads many patients to refuse the treatment and opt instead for liver resection or transarterial chemoembolization (TACE). Liver resection has been associated with 1-year overall survival (OS) rates of 22-70% for HCC patients with PVTT, which may be higher than with non-surgical treatments [<a class="elsevierStyleCrossRef" href="#bib0007">7</a>,<a class="elsevierStyleCrossRef" href="#bib0008">8</a>].

In contrast, TACE may be more effective for HCC patients with type III PVTT, while sorafenib may be more appropriate for patients with type IV PVTT.</p><p id="para0030" class="elsevierStylePara elsevierViewall">The optimal treatment for HCC patients with PVTT remains controversial. Some studies have highlighted the benefits of surgical treatment <a class="elsevierStyleCrossRefs" href="#bib0014">[14–17]</a>, since liver resection can unblock portal venous flow to decrease portal venous pressure and improve liver function, which can prolong survival and improve quality of life <a class="elsevierStyleCrossRef" href="#bib0007">[7]</a>. One study found that liver resection led to better outcomes than TACE for the treatment of HCC with PVTT <a class="elsevierStyleCrossRef" href="#bib0018">[18]</a>, but the other study of a larger cohort found the opposite result <a class="elsevierStyleCrossRef" href="#bib0009">[9]</a>. Our study helps explain the controversy in the literature by demonstrating that the best treatment may depend on the PVTT type. For example, we found that HCC patients with type I or II PVTT showed better OS after liver resection than after the other two treatments, consistent with a Japanese study <a class="elsevierStyleCrossRef" href="#bib0007">[7]</a>.</p><p id="para0031" class="elsevierStylePara elsevierViewall">Our results support the efficacy of TACE for treating HCC patients with type III PVTT. TACE blocks blood vessels that carry nutrients to the tumor, allowing chemotherapy to be delivered at high concentrations to cancer cells, while minimizing damage to healthy liver cells. TACE also reduces portal venous pressure and prevents formation of intractable ascites and bleeding esophageal varices <a class="elsevierStyleCrossRef" href="#bib0019">[19]</a>. In addition, our results suggest that for HCC patients with type IV PVTT, sorafenib may be preferable to resection or TACE given that it is non-invasive and associated with fewer complications than invasive treatments <a class="elsevierStyleCrossRef" href="#bib0020">[20]</a>. However, the drug should be used with caution given that it has been associated with greater risk of in-hospital mortality, high blood pressure, skin toxicity, and adverse gastrointestinal reactions [<a class="elsevierStyleCrossRef" href="#bib0006">6</a>,<a class="elsevierStyleCrossRef" href="#bib0021">21</a>]. In addition, sorafenib is not well tolerated in patients with reduced liver function <a class="elsevierStyleCrossRef" href="#bib0006">[6]</a>.</p><p id="para0032" class="elsevierStylePara elsevierViewall">Sorafenib is multi-kinase inhibitor that is approved for first-line treatment of patients with advanced hepatocellular carcinoma. However, the efficacy of targeted agents is modest, and they confer limited survival benefits. Immunotherapies, including PD -1 and PD-L1 inhibitors, have shown clinical benefits in various cancers. However, several phase 3 studies did not show superiority of anti-PD-1 monotherapy compared with standard of care for the first-line or second-line treatment of hepatocellular carcinoma <a class="elsevierStyleCrossRef" href="#bib0022">[22]</a>. Considering differences in the treatment efficacy of PD-1 and PD-L1 inhibitors across various tumor types, combination treatment with an anti-PD-1 antibody and an anti-angiogenesis agent might be a potential first-line treatment for patients with hepatocellular carcinoma. Ren et al reported [23] that compared with similar studies of first-line therapies for patients with advanced hepatocellular carcinoma, Sintilimab–bevacizumab biosimilar reduced the risk of death and disease progression. Sintilizumab-bevacizumab might be the first-line therapy for patients with advanced hepatocellular carcinoma, however, for the population of HCC patients with PVTT, the potential benefit of Sintilizumab-bevacizumab therapy is not known, Whether HCC patients with PVTT could benefit from Sintilizumab-bevacizumab therapy warrants future large cohort studies.</p><p id="para0033" class="elsevierStylePara elsevierViewall">While our retrospective analysis should be interpreted carefully given the risk of selection bias. In addition, the data could be affected by the differences in standards in surgical techniques and perioperative managements. And last, high prevalence of hepatitis B virus (HBV) may limit extrapolation of results to other patients.</p></span><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleLabel">5</span><span class="elsevierStyleSectionTitle" id="cesectitle0022">Conclusion</span><p id="para0034" class="elsevierStylePara elsevierViewall">In conclusion, our study suggested that the optimal treatment for HCC patients with PVTT may depend on their PVTT type.
