We encountered a case of hepatic portal lymph node metastasis after repeated treatment for hepatocellular carcinoma (HCC)recurrence. A 73-year-old male patient underwent partial gastrectomy following rupture of a gastrointestinal stromal tumor 8 years ago. A 70mm tumor was simultaneously revealed in the posterior segment of the liver, and imatinib treatment was initiated based on the diagnosis of a metastatic liver tumor. Due to the absence of an increasing tendency in the tumor, extended posterior segmentectomy was performed, and the pathological diagnosis was moderately differentiated HCC...

Peritoneal metastasis is relatively rare in patients with hepatocellular carcinoma(HCC). No consensus has been reached regarding the treatment of this type of metastasis. Herein, we report 3 patients who underwent resection of peritoneal metastasis due to HCC. Case 1: A 48-year-old man underwent hepatectomy twice and radiofrequency ablation(RFA)once for HCC. Eight years after the initial resection, he underwent resection of peritoneal metastasis in the pelvic floor. He is alive with disease 17 months after the last operation...

OBJECTIVE: We had previously proved that insufficient radiofrequency ablation (RFA) could enhance invasiveness and metastasis of hepatocellular carcinoma (HCC) through epithelial-mesenchymal transition (EMT), which is mediated by activating β-catenin signaling. Thus, the aim of the present study was to demonstrate whether the combined treatment of interferon-α (IFN-α) and "Songyou Yin" (SYY) minimizes the pro-metastatic effects of insufficient RFA, as well as to explore its underlying mechanism...

BACKGROUND: Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is already fully established worldwide. Needle tract implantation and peritoneal seeding occasionally occur by RFA, and the prognosis of these cases is thought to be poor. In this study, intraoperative real-time near-infrared fluorescence (NIRF) system by indocyanine green (ICG) incidentally detected both needle tract implantation and peritoneal seeding. As the utility of this system for identification of implanted and disseminated lesions after RFA for HCC has not been widely reported, we report a case of successful detection by real-time ICG-NIRF imaging and subsequent resection...

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) in the caudate lobe is technically challenging for both radiofrequency ablation (RFA) and transarterial chemoembolization (TACE). However, each of these modalities has its strengths. This retrospective study compares the effectiveness of RFA and TACE in patients with caudate HCC within the Milan criteria. METHODS: This study was approved by institutional review board. Between November 2005 and August 2016, we retrospectively reviewed 74 patients with a single HCC ≤ 5 cm or up to three HCCs ≤ 3 cm without vascular invasion or extrahepatic metastasis who were treated with RFA (n = 43) or TACE (n = 31)...

Recent studies indicated that insufficient radiofrequency ablation (RFA) could endow hepatocellular carcinoma (HCC) with higher aggressive potential. Stress-induced phosphoprotein 1 (STIP1), which was found highly expressed in HCC, is a chaperone molecule mediating cell homeostasis under thermal stress. We aimed to explore the role of STIP1 on the metastasis of residual HCC after RFA. Mice model with orthotopic HCC implants or caudal vein injection were employed to assess potential of lung metastasis and/or intrahepatic metastasis (IHM) of HCC cells...

The prognosis for hepatocellular carcinoma(HCC)with right atrium tumor thrombus(RATT)is dismal and necessary to be treated on as oncologic emergency. We report a case of HCC with RATT which was treated with multidisciplinary therapy including surgery. After repeated transarterial chemoembolization(TACE)and radiofrequency ablation(RFA), a 71-year-old man consulted to our hospital with multiple HCC, lung metastasis, and RATT. Left hemihepatectomy, thrombectomy of RATT, and 3 months of hepatic arterial infusion chemotherapy(HAIC)was performed, and intrahepatic HCCs were controlled...

The aim of the present study was to investigate the prognostic potential of a novel inflammation-based system, the combination of the neutrophil to lymphocyte ratio (NLR) and the platelet to lymphocyte ratio (PLR) (CNP), for predicting the survival time of patients with hepatocellular carcinoma (HCC) who had received radiofrequency ablation (RFA). A total of 287 HCC patients treated with RFA were enrolled in the study. Patients with an elevated NLR (>2.58) and an elevated PLR (>131.78) were allocated a score of 2, and patients exhibiting one or neither of these characteristics were allocated a score of 1 or 0, respectively...

Radiofrequency ablation (RFA) is one of the standards of care for early stage hepatocellular carcinoma (HCC). However, rapid progression of residual tumor after RFA has been confirmed. The aim of this study was to investigate the underlying mechanism of this phenomenon. Human HCC cell lines HCCLM3 and HepG2 were employed to establish insufficient RFA models in vivo and in vitro , respectively. The effects of insufficient RFA on metastatic potential of residual tumors were evaluated. The molecular changes after insufficient RFA were evaluated by PCR array, western blot, immunofluorescence, and immunohistochemistry...

INTRODUCTION: Peritoneal dissemination of hepatocellular carcinoma (HCC) is a rare presentation with an incidence of 2-6%. The most common cause of peritoneal deposits is a ruptured HCC that results in tumor spillage into the peritoneal cavity. The overall incidence of spontaneous ruptures of HCC ranges from 5 to 15% and carries a high mortality rate of up to 50%. Other factors influencing peritoneal dissemination are the lymph node metastasis and the direct diaphragmatic invasion and there is no significant association with past history of FNAB, or percutaneous RFA or ethanol injection and lung or adrenal metastasis...

There is no consensus regarding which therapeutic option is better and/or safer for treating hemodialysis (HD) patients with hepatocellular carcinoma (HCC). The present study compared surgical resection (Hx) and radiofrequency ablation (RFA) with regard to therapeutic efficacy in HD patients with HCC. Of 108 HD patients with naïve HCC treated at 15 institutions between 1988 and 2014 enrolled in the present study, 58 fulfilled the up-to-7 criteria [7 as the sum of the size of the largest tumor (cm) and the number of tumors] and were treated with Hx (n=23) or RFA (n=35); their clinical features, complications and prognosis were assessed...

Image-guided radiofrequency ablation (RFA) is an evolving and growing treatment option for patients with hepatocellular carcinoma (HCC) and hepatic metastasis. RFA offers significant advantages as it is less invasive than surgery and carries a low risk of major complications. However, serious complications, including aggressive tumor recurrence, may be observed during follow-up, and recently, mechanical or thermal damage during RFA has been proposed to be one of the causes of this kind of recurrence. Although the exact mechanism of this still remains unclear, physicians should be familiar with the imaging features of aggressive tumor recurrence after RFA for HCC and its risk factors...

Clinical observations have shown that the boundary of tumor ablation is often less than safe border and that the use of radiofrequency ablation (RFA) in the treatment of hepatocellular carcinoma (HCC) may probably accelerate its recurrence and metastasis. RFA can cause the formation of a transition zone between normal liver tissues and necrotic coagulation, where blood stagnation and thrombosis expose residual cancer cells to a hypoxic microenvironment. As the blocked vessels are slowly reperfused, the oxygen supply is gradually restored...

INTRODUCTION: A single-center nonrandomized clinical trial was performed to assess the safety and efficacy of IRE ablation of liver tumors in humans. METHODS: 38 malignant liver tumors on 30 patients were treated with IRE between September 2011 and September 2014. Treatment was with curative intent, and the diagnoses were colorectal cancer with liver metastases (CRLM) (n = 23), hepatocellular carcinoma (HCC) (n = 8) and other metastasis (n = 7). Patients were selected when surgery, radiofrequency ablation (RFA) or microwave ablation (MWA) was not an option, and when they met inclusion criteria (tumor size < 3 cm, 1-2 tumors)...
