Since Judah Folkman hypothesized in 1971 that angiogenesis is required for solid tumor growth, numerous studies have been conducted to unravel the angiogenesis process, analyze its role in primary tumor growth, metastasis and angiogenic diseases, and to develop inhibitors of proangiogenic factors. These studies have led in 2004 to the approval of the first antiangiogenic agent (bevacizumab, a humanized antibody targeting vascular endothelial growth factor) for the treatment of patients with metastatic colorectal cancer...

Dysregulation of long non-coding RNAs has been found in many human cancers, including colorectal cancer that is still the third most prevalent cancer worldwide and related to poor prognosis; along with this, robust testimony has identified that long non-coding RNAs can take charge of tumor suppressor genes or oncogenes. This review summarizes nowadays research achievements on the character of long non-coding RNAs in the prognosis and diagnosis of colorectal cancer. On the basis of the results acquired in the last decade, some long non-coding RNAs are rising as biomarkers of colorectal cancer for prognosis, diagnosis, even prediction of therapeutic result, and have crucial effects in the regulation of colorectal cancer cell functions such as proliferation, invasion, apoptosis, metastasis, and drug resistant ability...

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...

BACKGROUND: Standard surgical practice for colorectal cancer involves resection of the primary lesion and all draining lymph nodes. Accurate intraoperative assessment of nodal status could allow stratified resectional extent. One-step nucleic acid (OSNA) can provide a rapid method of interrogating nodal tissue, whilst near-infrared (NIR) laparoscopy together with indocyanine green (ICG) can identify relevant nodal tissue intraoperatively. METHODS: ICG was administered around the tumour endoscopically prior to the operation...

Metastasis is a multistep molecular network process, which is the major cause of death in patients with colorectal cancer (CRC). MicroRNAs (miRNAs) play pivotal roles in tumorigenesis as either tumor suppressors or oncogenes. Increased expression of fucosyltransferase4 (FUT4) has been reported to be associated with the invasive and metastatic properties of CRC. Here to identify potential key miRNAs and their target genes for colorectal cancer (CRC), we compared miRNA expression profiles between metastatic CRC cell SW620 and primary CRC cell SW480...

RATIONALE: All the enteric ganglion cells are fully mature by 2 to 5 years of age in human. No one had reported the presentation of immature enteric ganglion cells in elder ones. Colorectal carcinoma is also rare in the adolescent population. The coincidence of these 2 rare events in a 13-year-old boy has never been reported elsewhere, which may suggest some linkage between them. PATIENT CONCERN: A 13-year-old boy presented with progressive abdominal pain and melena for 3 months...

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...

Currently available studies have suggested that a number of exosome-encapsulated microRNAs (miRNAs) are recognized as stable biomarkers for cancers. However, little is known about the effect of exosomal miRNAs on colorectal cancer (CRC). The aim of study is to identify specific miRNAs in serum exosomes, which may serve as potential diagnostic and prognostic biomarkers and therapeutic targets for CRC. Microarray analyses of miRNAs in serum exosomes from 3 primary CRC patients and 3 healthy controls were performed...

The PIWI-like protein 1 (PIWIL1) plays a crucial role in stem cell proliferation, embryogenesis, growth, and development, as well as differentiation and maturation in multiple organisms. The relationships between PIWIL1 expression and clinicopathological features of colorectal cancer (CRC) patients were analyzed by us. Survival analysis was performed using the Kaplan-Meier method and Cox's proportional hazards model. The high expression rate of PIWIL1 in the cancer tissue was obviously higher than that in the corresponding adjacent tissue...

INTRODUCTION: Incidence of well-differentiated neuroendocrine tumors (NETs) of the colon and rectum is increasing and is now approximately 1 per 100,000 in the US. NETs are either well-differentiated (indolent) or poorly differentiated (aggressive). The majority of these tumors are found incidentally during screening colonoscopies and rarely are associated with symptoms of hormonal syndrome, even during the advanced stage. Metastatic well-differentiated NETs of the colon and rectum are incurable, hard to treat, and associated with a poor prognosis and survival rates similar to colorectal adenocarcinoma survival...

Increasing evidence suggests that the glutathione peroxidase 2 may actually play important roles in tumorigenesis and progression in various human cancers such as colorectal carcinomas and lung adenocarcinomas. However, the role of glutathione peroxidase 2 in gastric carcinoma remains to be determined. In this study, the expression and prognostic significance of glutathione peroxidase 2 in gastric carcinoma were investigated and the well-known prognostic factor Ki-67 labeling index was also assessed as positive control...

BACKGROUND: P21-activated kinase 1 (PAK1) stimulates growth and metastasis of colorectal cancer (CRC) through activation of multiple signalling pathways. Up-regulation of CRC stem cell markers by PAK1 also contributes to the resistance of CRC to 5-fluorouracil. The aim of this study was to investigate the effect of PAK1 depletion and inhibition on the immune system and on intestinal tumour formation in APC(∆14/+) mice. METHODS: The PAK1 KO APC(∆14/+) mice were generated by cross-breeding of PAK1 KO mice with APC(∆14/+) mice...

A major problem associated with colon cancer is liver metastasis. A colon-targeted drug delivery system is one way to address this problem after the resection of colorectal cancer. However, traditional drug delivery systems face many challenges, such as an inability to control the release rate, inaccurate targeting, susceptibility to the microenvironment and poor stability. Here, we report the development of a graphene oxide (GO)-based, sodium alginate (ALG) functionalized colon-targeting drug delivery system, that is loaded with 5-fluorouracil (5-FU) as the anti-cancer drug (denoted as GO-ALG/5-FU)...

Approximately 9% of cancer-related deaths are caused by colorectal cancer. Liver metastasis is a major factor for the high colorectal cancer mortality rate. However, the molecular mechanism underlying colorectal cancer liver metastasis remains unclear. Using a global and multidimensional integration approach, we studied sequencing data, protein-protein interactions, and regulation of transcription factor and non-coding RNAs in primary tumor samples and liver metastasis samples to unveil the potential bridging molecules and the regulators that functionally link different stages of colorectal cancer liver metastasis...
