Development and progression of malignant tumors is in part characterized by the ability of a tumor cell to overcome cell-cell and cell-matrix adhesion and to disseminate in organs distinct from that in which they originated. This study was undertaken to analyze the clinical significance of the expression of the following cell-cell and cell-matrix adhesion molecules in pancreatic ductal adenocarcinomas (PDACs) and synchronous liver metastases: intercellular adhesion molecule 1 (ICAM-1), E-cadherin, periostin, and midkine (MK)...

OBJECTIVE: To investigate the clinicopathological features and prognosis of colorectal synchronous multiple primary cancer(SMPC). METHODS: From January 2008 to June 2011, 51 patients diagnosed with colorectal SMPC underwent surgery at Department of General Surgery of Peking University First Hospital. Their clinicopathological features, diagnosis, treatment and prognosis were summarized and analyzed. SMPC was diagnosed according to the following criteria: each tumor must have a definite pathologic picture of malignancy; metastasis or recurrence from another colorectal cancer was excluded; tumors must be distinctly separated by at least 5 cm of all intact bowel wall from each other; SMPC has abnormal cells between tumor and normal mucosa and abnormal gland of transitional zone; each cancer is infiltrating carcinoma except the carcinoma in situ; all the cancers are detected at the same time or within 6 months...

Leiomyosarcoma is a rare type of malignant soft tissue tumor and also one of the most aggressive soft tissue sarcomas. It commonly occurs in uterus, abdominal viscera, retroperitoneal space and soft tissue of the extremities. Primary osseous leiomyosarcoma is a rare condition. Furthermore, primary leiomyosarcoma of the spine is extremely rare. Only few cases have been reported. However, the treatment and outcomes remains controversial. Therefore, the objective of this case report is to illustrate the management of this extremely rare disease by using total en bloc spondylectomy (TES) procedure, which is one of a suitable option for surgical resection of the spinal tumors...

BACKGROUND: The ability to provide accurate prognostic data after hepatectomy for intrahepatic cholangiocarcinoma (ICC) remains poor. We sought to develop and validate a nomogram to predict survival, as well as investigate the clinical implications of underestimating patients' risk of recurrence. METHODS: Patients undergoing curative-intent resection of ICC between 1990 and 2015 at 14 major hepatobiliary centers were included. Variables significant on multivariable analysis were used to construct a nomogram to predict disease-free survival (DFS)...

CXCR4 is the most common chemokine receptor expressed on the surface of many cancer cell types. In comparison to normal cells, cancer cells overexpress CXCR4, which correlates with cancer cell metastasis, angiogenesis, and tumor growth. CXCR4 antagonists can potentially diminish the viability of cancer cells by interfering with CXCL12-mediated pro-survival signaling and by inhibiting chemotaxis. Herein, we describe a series of CXCR4 antagonists that are derived from (S)-5,6,7,8-tetrahydroquinolin-8-amine that has prevailed in the literature...

DEP Domain Containing 7 (DEPDC7) is highly and specifically expressed in normal liver tissue, belonging to the class of genes of liver-selective cell communication. Although the function of DEPDC7 remains poorly understood, its expression is decreased in liver cancer compared with normal liver tissues. It has previously been demonstrated that knockdown of DEPDC7 promotes cell growth, S phase entry and cell mobility and invasion in HepG2 cells. In the present study, it was shown that DEPDC7 expression is downregulated in four hepatoma cell lines (SMMC-7721, Huh-7, SK-Hep-1 and HepG2) and 48 hepatoma tissues, determined using western blot and immunohistochemical analysis...

BACKGROUND: Although adjuvant chemotherapy (AC) is widely used after liver resection (LR) for colorectal liver metastasis (CRLM), surgical invasiveness may lead to delay in starting AC, which is preferably started within 8 weeks postoperative. We investigated whether laparoscopic liver resection (LLR) for CRLM facilitates AC start without delay. METHODS: Between November 2014 and December 2016, 117 consecutive CRLM patients underwent LR followed by AC. LLR and OLR were performed in 30 and 87 patients, respectively...

S-adenosyl methionine (SAM) is a ubiquitous methyl donor that was reported to have chemo- protective activity against liver cancer, however the molecular footprint of SAM is unknown. We show here that SAM selectively inhibits growth, transformation and invasiveness of hepatocellular carcinoma cell lines but not normal primary liver cells. Analysis of the transcriptome of SAM treated and untreated liver cancer cell lines HepG2 and SKhep1 and primary liver cells reveals pathways involved in cancer and metastasis that are upregulated in cancer cells and are downregulated by SAM...

We investigated whether the concept of oligometastasis may be introduced to the clinical management of metastatic bladder cancer patients. Our study population comprised 128 patients diagnosed with metastatic bladder cancer after total cystectomy at our 6 institutions between 2004 and 2014. We extracted independent predictors for identifying a favorable. Occurrence that fulfilled all 4 criteria which were independently associated with cancer-specific death was defined as oligometastasis: a solitary metastatic organ; number of metastatic lesions of 3 or less; the largest diameter of metastatic foci of 5cm or less; and no liver metastasis...

Hypervirulent K. pneumoniae variants (hvKP) have been increasingly reported worldwide, causing metastasis of severe infections such as liver abscesses and bacteremia. The capsular serotype K2 hvKP strains show diverse multi-locus sequence types (MLSTs), but with limited genetics and virulence information. In this study, we report a hypermucoviscous K. pneumoniae strain, RJF293, isolated from a human bloodstream sample in a Chinese hospital. It caused a metastatic infection and fatal septic shock in a critical patient...

Polymorphisms of the Lysosomal-Associated Protein Transmembrane-4 beta (LAPTM4B) gene are related to various forms of tumour susceptibility, which led us to hypothesize that some unique transcription factors targeting this polymorphism region may affect the biological function of LAPTM4B in tumour progression. In this study, we found that the transcription factor AP4 directly binds to the polymorphism region of the LAPTM4B gene promoter and induces its transcription. In addition, we demonstrated that AP4 promotes hepatocellular carcinoma cell proliferation and metastasis, and depresses chemotherapy sensitivity via LAPTM4B by activating the PI3K/AKT signalling pathway and caspase-dependent pathway...

Surgery remains the curative treatment modality for colorectal cancer in all stages, including stage IV with resectable liver metastasis. There is emerging evidence that the stress response caused by surgery as well as other perioperative therapies such as anesthesia and analgesia may promote growth of pre-existing micro-metastasis or potentially initiate tumor dissemination. Therapeutically targeting the perioperative period may therefore reduce the effect that surgical treatments have in promoting metastases, for example by combining β-adrenergic receptor antagonists and cyclooxygenase-2 (COX-2) inhibitors in the perioperative setting...
