BACKGROUND: Whether surgical resection for recurrent biliary tract carcinoma (BTC) prolongs survival and the patients who are most likely to benefit from such treatment remain unclear. METHODS: Among 251 patients with recurrences after the initial resection of BTC, a total of 21 patients (8.4%) underwent surgical resection for the recurrence, with a zero mortality rate. The clinicopathological features of these patients were compared with those of patients who did not undergo surgery...

Candice Alexandra Grzelak, Cyrus Michael Ghajar
Disseminated breast tumor cells reside on or near stable microvascular endothelium. Currently, the cues that disrupt DTC dormancy and facilitate outgrowth are largely unknown. This article explores the hypothesis that specific patient lifestyle exposures (e.g., alcohol abuse) may disrupt the microenvironments that maintain disseminated tumor cell (DTC) dormancy in a tissue-specific fashion. We suggest that such exposures are 'transmitted' to the dormant niche in the form of injury. Thus, we discuss the relationship between wound healing and metastasis using liver as an example to illustrate how injury steers the phenotype of liver endothelium and perivascular hepatic stellate cells to a potentially pro-metastatic one...

PARP-1 (poly(ADP-ribose) polymerase-1) plays an important role in tumorigenesis. Since its effects on different populations are varied, this study investigated the impact of PARP-1 on primary hepatocellular carcinoma in a Southern Chinese Zhuang population. We assessed the global PARP-1 messenger RNA expression in patients with hepatocellular carcinoma using The Cancer Genome Atlas dataset. Increased PARP-1 expression, related to alpha-fetoprotein level, was observed. The area under the receiver operating characteristic curve value was 0...

Hepatocellular carcinoma is one of the most prevalent neoplasms and the leading cause of cancer-related mortality worldwide. Mitochondrial ribosomal protein S23 is encoded by a nuclear gene and participates in mitochondrial protein translation. Mitochondrial ribosomal protein S23 overexpression has been found in many types of cancer. In this study, we explored mitochondrial ribosomal protein S23 expression in primary hepatocellular carcinoma tissues compared with matched adjacent non-tumoral liver tissues using mitochondrial ribosomal protein S23 messenger RNA and protein levels collected from public databases and clinical samples...

Exosomes play important roles in cell-cell communication, and are likely mediators of the metastatic cascade in cancer. This study examined the role of exosomes in pancreatic cancer cell adhesion, migration, and invasion. We isolated and purified exosomes from two isogenic pancreatic cancer cell lines with different metastatic potentials. Uptake of exosomes from highly metastatic Panc02-H7 cells decreased adhesion and increased migration and invasion capacity in weakly metastatic Panc02 cells in vitro. Exosomes from highly metastatic pancreatic cancer cells induced liver pre-metastatic niche formation in naïve mice and promoted primary tumor growth and liver metastasis in vivo...

BACKGROUND: Surgical resection is an established therapeutic strategy for colorectal cancer (CRC) metastasis. However, controversies exist when CRC liver and lung metastases (CLLMs) are found concomitantly or when recurrence develops after either liver or lung resection. No predictive score model is available to risk stratify these patients in preparation for surgery, and cure has not yet been reported. PATIENTS AND METHODS: All consecutive patients who had undergone surgery for CLLMs at our institution during a 20-year period were reviewed...

The prognosis for patients who are diagnosed with advanced stage hepatocellular carcinoma (HCC) is poor because there are few treatment options. Recent research has focused on the identification of novel molecular entities that can be targeted to inhibit oncogenic signals that are involved in the carcinogenesis, proliferation and progression of HCC. Among all of the pathways that are involved in the development of HCC, Hedgehog (HH) signalling has demonstrated a substantial role in hepatocarcinogenesis and HCC progression...

BACKGROUND: Recent genetic studies have highlighted that alterations in MEN1, chromatin remodeling genes, and mammalian target of rapamycin (mTOR) pathway genes are the most frequent molecular events identified in pancreas neuroendocrine tumors (pNETs). The prognostic or predictive impact of these biomarkers and other less frequently observed aberrations, i.e. PTEN, TSC2 and PIK3CA are relatively unknown. The aims of this targeted next generation sequencing (NGS) study were to assess tumor cytology genotype diversity, to survey for potential adverse prognostic biomarkers and the prevalence of mTOR pathway variants...

The liver X receptors (LXRs) is an important component of the nuclear receptor (NR) superfamily. Previous studies have shown that the LXRs possessed antitumor activity in various types of tumor cells. However, the complicated mechanisms underlying the antitumor activity remain largely unexplored. In this study, we incubated A549 cells with the compound T0901317, a specific LXRs agonist, for 24 h. The MTT assay was used to assess cell viability. Transwell assays were used to evaluate cell migration and invasion...

The ability to generate potent immunotherapies locally and transiently for the treatment of cancers is a promising strategy to improve efficacy and decrease off-target toxicities. Here, we explored an alternative approach for the delivery of immunotherapeutic agents, in which we deliver the pDNA of an engineered PD-L1 trap and/or CXCL12 trap to the nucleus of liver hepatocytes via a lipid calcium phosphate nanoparticle. This strategy greatly increased the concentrations of immunotherapeutic agents in the local tissue, allowing the therapy to inhibit the accumulation of immune suppressive cells and liver metastasis...

During intravasation, circulating tumor cells (CTCs) detach from the epithelium of origin and begin the Epithelial-to Mesenchymal-Transition (EMT) process, where they lose epithelial features and pass through the endothelium to enter circulation. Although detachment from the extracellular matrix is a strong source of metabolic stress, which induces anoikis, CTCs can survive. Recently, the tumor suppressor liver kinase B1 (LKB1) has gained attention for its role as a proto-oncogene in restoring the correct ATP/AMP ratio during metabolic stress...
