Pathological studies of resected HCC specimens reported that microscopic intrahepatic metastases are present in about 10% of patients with a solitary HCC measuring 2 cm or less. Microvascular invasion is also present in about 27% of patients [3]. Based on these facts, it is believed that there is a certain risk of recurrence of intrahepatic metastasis, even for a single nodule measuring 2 cm or less. Furthermore, the larger the tumor, or the presence of multiple HCCs larger than 2 cm, increases the risk of intrahepatic metastasis and microvascular invasion, and therefore the risk of intrahepatic metastatic recurrence [4, 5]. There are two patterns of recurrence after curative treatment: early and late. Early recurrence involves mainly intrahepatic metastasis via the portal vein, while late recurrence has a more multicentric etiology [2]. About 80% of HCCs recur 5 years after RFA or resection [6]. The main reason for the poor prognosis associated with HCC is frequent recurrence, even after curative treatment. Repeated TACE to treat recurrence worsens liver function in many cases, resulting in death from liver failure. Conversely, if HCC recurrence after curative treatment can be suppressed, the prognosis should improve dramatically. Several adjuvant trials have been conducted to inhibit recurrence, but all yielded negative results [7–9]. To date, representative clinical trials of adjuvants that help to prevent recurrence include a trial of Vitamin K [7], the NIK-333 trial that used retinoid [8], and the STORM trial","PeriodicalId":18156,"journal":{"name":"Liver Cancer","volume":"12 3","pages":"189-197"},"PeriodicalIF":13.8,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/f4/57/lic-2023-0012-0003-531225.PMC10360452.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10291505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The IMbrave150 trial demonstrated that atezolizumab and bevacizumab therapy (ABT) has better treatment outcomes than sorafenib for advanced HCC.

We report the first case of ABT for advanced FLHCC followed by hepatectomy presenting pseudoprogression of lymph node (LN) metastases which was pathologically proven after surgery.\u0000The patient was a 30-year-old man with advanced FLHCC and multiple LN metastases behind the pancreatic head, and ABT was introduced. After four courses of treatment, CT indicated a minor decrease in the intratumor vascularity of the liver tumor. However, the size of metastatic LNs increased. Subsequently, the patient presented with bloody stool, and colonoscopy revealed immune-related colitis caused by atezolizumab. Therefore, the fifth course was canceled. A right hemihepatectomy following percutaneous transhepatic portal vein embolization (PTPE) was performed to increase the future liver remnant volume. After PTPE, dynamic CT revealed an objective response to ABT; SD in RECIST 1.1 (7% increase in the LN size and no change of liver tumor), and PR in modified RECIST (47% decrease in the intratumor vascularity of the liver tumor and LNs). Three weeks after PTPE, right hemihepatectomy plus nodal dissection was successfully performed. Pathological findings revealed that approximately 60%–70% of the liver tumor and 70%–80% of the metastatic LNs were necrotic, indicating a good response to ABT. The increasing size of metastatic LNs that occurred during the treatment course was deemed pseudoprogression. Pseudoprogression can be found in patients with solid malignancies treated with immune checkpoint inhibitors, however, rarely occurs in HCC. The first response to metastatic LNs was observed 20 weeks after ABT initiation combined with an increase in nodal volume and a decrease in vascularity. In the updated data of the IMbrave150 trial, 19% of the first responses occurred after week 24.
