OBJECTIVE: To assess the correlation between recurrence-free survival (RFS) and overall survival (OS) in the hepato-biliary-pancreatic (HBP) surgical setting in order to validate RFS as a surrogate endpoint. SUMMARY BACKGROUND DATA: Reliable surrogate endpoints for OS are still limited in the field of HBP surgery. METHODS: We analyzed patients who underwent curative resection for HBP disease (986 patients with pancreatic ductal adenocarcinoma [PDAC], 1168 with biliary tract cancer [BTC], 1043 with hepatocellular carcinoma [HCC], and 1071 with colorectal liver metastasis [CRLM]) from September 2002 to June 2022...

One area of cancer research is the interaction between cancer cells and immune cells, in which chemokines play a vital role. Despite this, a comprehensive summary of the involvement of C-X-C motif ligand 1 (CXCL1) chemokine (also known as growth-regulated gene-α (GRO-α), melanoma growth-stimulatory activity (MGSA)) in cancer processes is lacking. To address this gap, this review provides a detailed analysis of CXCL1's role in gastrointestinal cancers, including head and neck cancer, esophageal cancer, gastric cancer, liver cancer (hepatocellular carcinoma (HCC)), cholangiocarcinoma, pancreatic cancer (pancreatic ductal adenocarcinoma), and colorectal cancer (colon cancer and rectal cancer)...

BACKGROUND: Excessive extracellular matrix deposition and increased stiffness are typical features of solid tumors such as hepatocellular carcinoma (HCC) and pancreatic ductal adenocarcinoma (PDAC). These conditions create confined spaces for tumor cell migration and metastasis. The regulatory mechanism of confined migration remains unclear. METHODS: LC-MS was applied to determine the differentially expressed proteins between HCC tissues and corresponding adjacent tissue...

BACKGROUND: Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related death worldwide. Due to the high prevalence of hepatitis B virus (HBV) infection in China, the incidence of HCC in China is high, and liver cirrhosis caused by chronic hepatitis also brings great challenges to treatment. This paper reviewed the latest research progress on minimally invasive treatments for HCC, including percutaneous thermal ablation and new nonthermal ablation techniques, and introduced the principles, advantages, and clinical applications of various therapeutic methods in detail...

Introduction: Right anterior sectionectomy (RAS) is technically difficult and performed infrequently, so there were a few reports of small numbers about this surgery. We described large number of clinicopathologic and oncologic outcomes associated with RAS. Methods: We retrospectively reviewed the medical records of 415 patients treated with RAS for hepatic tumors located at segment 5 and/or 8 between January 2008 and December 2017. Results: All patients underwent RAS with the alternative Glissonean pedicle clamp and Kelly clamp-crushing methods for transection...

Introduction: Laparoscopic hepatectomy has been accepted widely due to its advantages as a minimally invasive surgery, but laparoscopic right posterior sectionectomy (LRPS) has rarely been reported. Tumors located over the right posterior section are considered to be difficult for laparoscopic resection. The Glissonean approach is our technique of choice. The aim of this work is to present our experience in LRPS in semi prone position and to show surgical technical aspects. Methods: For six years period we were performed 12 LRPS procedures...

Lecture: Surgery is the gold standard for treatment in patients with resectable colorectal liver metastasis (CRLM), with reported 5-year survival rates ranging from 40% to 60%. Unfortunately, only 10%-25% of patients with CRLM are considered eligible for liver resection (LR). In others, extensive tumor burden within the liver or poor anatomical position of the tumors close to critical vascular or biliary structures precludes resection. In these patients, systemic therapy is offered with the goal of improving survival or potentially converting patients into surgical resection candidates...

Dear members and colleagues, it is my great honor being the president of our society, Korean Association of HBP Surgery over the last year and being here to present my talk today as well. Ulsan University Hospital (UUH) was designated as a university hospital in March 1997 but was not gaining the trust of the local people at the time. It had been a general hospital and not specialized in the care of malignancy or organ transplantation. When I was appointed to the UUH in 2001, I thought about how to gain the trust of the local people...

A major mitochondrial enzyme for protecting cells from acetaldehyde toxicity is aldehyde dehydrogenase 2 (ALDH2). The correlation between ALDH2 dysfunction and tumorigenesis/growth/metastasis has been widely reported. Either low or high ALDH2 expression contributes to tumor progression and varies among different tumor types. Furthermore, the ALDH2∗2 polymorphism (rs671) is the most common single nucleotide polymorphism (SNP) in Asia. Epidemiological studies associate ALDH2∗2 with tumorigenesis and progression...

INTRODUCTION: In 2018, Hepatocellular carcinoma (HCC) was predicted to be the sixth most commonly diagnosed cancer. Extra-hepatic metastasis due to HCC is a poor prognostic factor, depending on the stage of the disease. PRESENTATION OF CASE: We report a case of a 52-years old male who had undergone Segment 5 (S5) hepatectomy for HCC of 4.7 × 2 cm. Transcatheter arterial chemoembolization (TACE) four times postoperatively was performed based on a preoperative diagnosis of a recurrent tumour at the S1...

A 75-year-old woman underwent transcatheter chemoembolization(TACE)for 2 small hepatocellular carcinoma(HCC) lesions associated with severe alcoholic liver cirrhosis that necessitated management for ascites. Over 5 years after the initial TACE, she received multidisciplinary therapies with TACE, transcatheter arterial infusion of anticancer agents, percutaneous ethanol injections, or percutaneous radiofrequency ablation performed on 5 occasions for small recurrent HCC lesions. Computed tomography performed after the last therapy for HCC revealed a solitary lymph node swelling(39 mm in diameter) around the common hepatic artery...

Cancer associated fibroblasts (CAF) and the extracellular matrix (ECM) produced by them have been recognized as key players in cancer biology and emerged as important targets for cancer treatment and drug discovery. Apart from their presence in stroma rich tumors, such as biliary, pancreatic and subtypes of hepatocellular cancer (HCC), both CAF and certain ECM components are also present in cancers without an overt intra-tumoral desmoplastic reaction. They support cancer development, growth, metastasis and resistance to chemo- or checkpoint inhibitor therapy by a multitude of mechanisms, including angiogenesis, ECM remodeling and active immunosuppression by secretion of tumor promoting and immune suppressive cytokines, chemokines and growth factors...

Hepatocellular carcinoma (HCC) and primary pancreatic cancer are common malignant tumors of the digestive system. However, there are significant differences in treatment methods, medication types, and survival prognoses. For patients whose imaging findings suggest there to be a significant pancreatic mass and multiple masses in the liver, it can be easily misdiagnosed as a primary pancreatic cancer with liver metastasis in the clinic instead. Therefore, patients with a high likelihood of primary pancreatic cancer based on their clinical data, the pathological diagnosis should be confirmed through a needle biopsy as early as possible to avoid a misdiagnosis and possible mistreatment...

This study will assess the safety and efficacy of the administration of adenoviral vector expressing the human-reduced expression in immortalized cells (Ad-REIC) to a liver tumor in patients with hepatocellular carcinoma (HCC) or liver metastasis of pancreatic cancer. A Phase I clinical study of Ad-REIC administration to a liver tumor in a patient with HCC or liver metastasis of pancreatic cancer will be conducted. The study is a single-arm, prospective, nonrandomized, noncomparative, open-label, single-center trial performed in Okayama University Hospital, Okayama, Japan...

BACKGROUND: Portal annular pancreas (PAP) is a rare congenital anatomical abnormality of the pancreas in which the portal vein is encircled by aberrant parenchyma, and special attention is needed for pancreatic resections. This is the first report of central pancreatectomy (CP) in a PAP for metastatic renal cell carcinoma (RCC). CASE PRESENTATION: A 76-year-old man who had a history of left nephrectomy for renal cancer not otherwise specified 36 years earlier and radical cystectomy for bladder cancer 4 years earlier was incidentally found to have a pancreatic tumor and a liver tumor...

Exosomes are emerging as essential vehicles mediated cross-talk between different types of cells in tumor microenvironment. The extensive exploration of exosomes in hepatocellular carcinoma (HCC) enhances our comprehension of cancer biology referring to tumor growth, metastasis, immune evasion, and chemoresistance. Besides, the versatile roles of exosomes provide reasonable explanations for the propensity for liver metastasis of gastric cancer, pancreatic ductal adenocarcinoma, breast cancer, and colorectal cancer...

Decoy receptor 3 (DcR3) has been recently described as an antiapoptosis and prometastasis factor since it can competitively bind to FasL, TL1A, and LIGHT, and it is highly expressed in many malignant tumors. Downregulation of DcR3 can promote tumor cell apoptosis and inhibit metastasis. A previous study demonstrated that reduction of DcR3 could induce tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis in pancreatic cancer cells. However, whether such an effect is seen in hepatocellular carcinoma (HCC) remains to be explored...

Hepatocellular carcinoma (HCC) is a major cause of cancer-related death worldwide. As vectors for intercellular information exchange, the potential role of extracellular vesicles (EVs) in HCC formation, progression and therapy has been widely investigated. In this review, we explore the current status of the researches in this field. Altogether there is undeniable evidence that EVs play a crucial role in HCC development, metastasis. Moreover, EVs have shown great potential as drug delivery systems (DDSs) for the treatment of HCC...

The liver is a common site of metastasis, with essentially all metastatic malignancies having been known to spread to the liver. Nearly half of all patients with extrahepatic primary cancer have hepatic metastases. The severe prognostic implications of hepatic metastases have made surgical resection an important first line treatment in management. However, limitations such as the presence of extrahepatic spread or poor functional hepatic reserve exclude the majority of patients as surgical candidates, leaving chemotherapy and locoregional therapies as next best options...

Fludeoxyglucose F 18 ((18)F-FDG) PET/CT has not been shown to offer additional benefit in the initial diagnosis of pancreatic cancer, but studies show benefit of (18)F-FDG PET/CT in initial staging and patient prognosis. There is evidence for (18)F-FDG PET and (18)F-FDG PET/CT in staging and prognosis of cholangiocarcinoma and gallbladder cancer. (18)F-FDG PET/CT has shown promise in staging liver malignancies by detecting extrahepatic metastasis. There is evidence supporting the ability of PET/CT in predicting prognosis in patients with hepatocellular carcinoma...
