We investigated the functional role and clinical significance of Stearoyl CoA desaturase-1 (SCD1) mediated endoplasmic reticulum (ER) stress in regulation of liver tumor-initiating cells (T-ICs) and sorafenib resistance, aiming to develop a novel therapeutic strategy against hepatocellular carcinomas (HCCs) METHODS We evaluated the clinic-pathological relevance of SCD1 and its correlation with sorafenib resistance in large cohorts of HCC clinical samples by qPCR and immunohistochemical analyses. Lentiviral-based overexpression and knockdown approaches were performed to characterize functional roles of SCD1 in regulation of liver T-ICs and sorafenib resistance...

It has been reported that long non-coding RNA PANDA was disregulated in varieties types of tumor, but its expression level and biological role in hepatocellular carcinoma (HCC) remains contradictory. We detected PANDA expression in two independent cohorts (48 HCC patients following liver transplantation and 84 HCC patients following liver resection), and found that PANDA was down-regulated in HCC. Thereafter we explored its function in cancer biology by inversing its low expression. Surprisingly, overexpression of PANDA promoted HCC proliferation and carcinogenesis in vitro and in vivo...

Parenchymal transection during hepatobiliary surgery can disrupt small vasculature or bile ducts, which could be managed difficultly. Sealants are helpful tools to achieve better hemostasis. The aim of this study is to analyze the hemostatic efficiency of four modern sealants in a porcine model. In this study, 40 landrace pigs were assigned equally to the control (without sealant) and four sealant groups. Standardized liver resection and splenic lesions were performed and left without using sealant (control) or treated with one of the following sealants: TachoSil(®) , Tissucol Duo(®) , Coseal(®) , and FloSeal(®) ...

Hepatocellular carcinoma (HCC) management has evolved in the last decades. Current available treatments include interventional radiology like radiofrequency ablation, transarterial chemoembolization or Yttrium 90 radioembolization. Surgery, when possible, has been proven to be the most effective treatment in reducing the risk of long-term local recurrence. American and European societies (AASLD, EASL, respectively) guidelines for the management of HCC endorse The Barcelona Clinic Liver Cancer (BCLC) treatment allocation system...

BACKGROUND: Central venous pressure often fails to identify the true value of cardiac preload. Our purpose is to investigate whether Global End-Diastolic Volume (GEDV) values can control hemodynamic parameters for the measurement of fluid volume, cardiac preload and blood loss during liver transection. METHODS: This was a prospective clinical study that included patients undergoing liver resection. All patients were monitored by means of PiCCO technology and 222 hemodynamic measurements were performed in 74 patients...

Colorectal liver metastasis (CRLM) is one of the most difficult and key points in the treatment of colorectal cancer. Approximately 50% to 60% of patients diagnosed as colorectal cancer develops metastasis, and 80% to 90% of CRLM is unresectable. Surgical resection is the first-line treatment for CRLM, while it is only suitable for about 15% patients. Systemic chemotherapy can prolong the survival of CRLM patients, however, a part of CRLM patients are resistant to chemotherapy. With the development of technology and the update of clinical evidence, individual therapy with target drugs and multidisciplinary treatment (MDT) have became a tendency, and minimally invasive interventional therapy has gained more acceptance in the MDT mode of the treatment for CRLM...

Rectal cancer with simultaneous liver metastasis is very common clinically. R0 surgical resection both for the original and metastatic tumor can achieve much better long-term oncological results. The operation types include traditional open procedures for both rectal cancer and liver metastatic resection; combination of laparoscopic resection of the rectal cancer and open procedure resection of the liver metastatic lesion; traditional laparoscopic-assisted rectal and liver metastatic tumor resection with small abdominal incision and total laparoscopic natural orifice specimen extraction surgery(NOSES) without abdominal incision...

Cell death pathway plays an important role in apoptosis, and corruption of this signaling pathway has been shown to participate in carcinogenesis. We aimed at determining whether genetic variants in CASP8, CASP10 and CFLAR influence the development and clinical outcomes of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). A hospital-based case-control study, including 600 HCC cases and 600 HBsAg positive controls without HCC, was conducted to assess the relationship between 11 tagging SNPs in CASP8, CASP10 and CFLAR and HBV-related HCC risk and prognosis in a Chinese Han population...

Metastatic esophageal adenocarcinoma to the urinary bladder is extremely rare. We describe a previously healthy 49-year-old female with recent diagnosis of adenocarcinoma of the gastroesophageal junction with metastatic disease to the liver. Biopsy was positive for human epidermal growth factor receptor 2 (HER2) by Fluorescence In Situ Hybridization (FISH). She received six cycles of Cisplatin, 5-Fluorouracil, and Herceptin and subsequently developed symptomatic anemia and hematuria. Cystoscopy with retroflexion was performed and she received a transurethral resection of bladder tumor with fulguration...

Small for size and flow syndrome (SFSF) is one of the most challenging complications following extended hepatectomy (EH). After EH, hepatic artery flow decreases and portal vein flow increases per 100 gram remnant liver volume (RLV). This causes hypoxia followed by metabolic acidosis. A correlation between acidosis and post-hepatectomy liver failure has been postulated, but not studied systematically in a large animal model or clinical setting. In our study, we performed stepwise liver resections on nine pigs to defined SFSF limits as follows: step 1: segment II/III resection, step 2: segment IV resection, step 3: segment V/VIII resection (RLV: 75%, 50% and 25% respectively)...

The Platelet to lymphocyte ratio (PLR) has been reported to predict prognosis of patients with hepatocellular carcinoma (HCC). This study examined the prognostic potential of stratified PLR for HCC patients undergoing curative liver resection. Medical records were retrospectively analyzed for 778 HCC patients undergoing curative liver resection at the Affiliated Tumor Hospital of Guangxi Medical University and the First People's Hospital of Changde between April 2010 and October 2013. Patients were stratified based on quintile analysis of their preoperative PLR, and patients in different quintiles were analyzed for overall survival (OS) and disease-free survival (DFS) using Kaplan-Meier analysis...

Disruption of the cell cycle pathway has previously been related to development of human cancers. However, associations between genetic variants of cell cycle pathway genes and prognosis of hepatocellular carcinoma (HCC) remain largely unknown. In this study, we evaluated the associations between 24 potential functional single nucleotide polymorphisms (SNPs) of 16 main cell cycle pathway genes and disease-free survival (DFS) of 271 HCC patients who had undergone radical surgery resection. We identified two SNPs, i...

BACKGROUND AND AIM: The inflammatory response accelerates early liver regeneration after liver injury and resection. Recent studies have demonstrated that indoleamine 2,3-dioxygenase-1 (IDO1) suppresses the activation of inflammatory cells and induces immune tolerance. In this study, we examined the role of IDO1 in liver regeneration after partial hepatectomy (PHx). METHODS: WT or IDO1-knockout (IDO1-KO) mice received 70% PHx. The liver-body weight ratio after PHx was measured and hepatocyte growth was assessed by immunostaining...

BACKGROUND: Repeat liver resection is an effective treatment, with long-term surgical outcomes for recurrent hepatocellular carcinoma and colorectal liver metastasis. However, the efficacy of a minimally invasive surgical approach for recurrent liver cancer is not yet confirmed. The purpose of this study is to examine the efficacy of minimally invasive repeat liver resection (MISRLR) compared with open repeat liver resection (ORLR) for primary and metastatic liver cancer. Here, we retrospectively analyzed the clinicopathological features and short-term surgical outcomes of patients undergoing MISRLR and ORLR...
