Stage 4 colorectal cancer

Jian Zhao, Jian Xu, Rui Zhang
Colorectal cancer (CRC) is the third most prevalent cancer and the fourth most common cause of cancer-associated mortality in males and females globally. Aberrant expression of microRNA-539 (miR-539) has been reported in multiple types of cancer. However, miR-539 expression, function and underlying mechanisms have not been clearly elucidated in CRC. In the present study, miR-539 expression was detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) in CRC tissues and cell lines. The effects of miR-539 on CRC cells were further examined in in vitro studies...

BACKGROUND: Colorectal neoplasia differentially expressed (CRNDE), a 1910-nt lncRNA encoded on human chromosome 16, has been found to be involved in various cancers. Nevertheless, the clinical and diagnostic values of CRNDE in tumors still need to be explored. In this review, we aimed to elucidate the clinical role of CRNDE in cancer by searching all correlative literature, and we sequentially explored the association between CRNDE levels and overall survival (OS) or clinicopathological characteristics of cancer...

BACKGROUND: In patients with stage IV colorectal cancer (CRC), minimally invasive surgery (MIS) may offer optimal oncologic outcome with low morbidity. However, the relative benefit of MIS compared to open surgery in patients requiring multistage resections has not been evaluated. METHODS: Patients who underwent totally minimally invasive (TMI) or totally open (TO) resections of CRC primary and liver metastases (CLM) in 2009-2016 were analyzed. Inverse probability of weighted adjustment by propensity score was performed before analyzing risk factors for complications and survival...

It is increasingly appreciated that host factors within the tumor centre and microenvironment play a key role in dictating colorectal cancer (CRC) outcomes. As a result, the metastatic process has now been defined as a result of epithelial-mesenchymal transition (EMT). Establishment of the role of EMT within the tumor centre and its effect on the tumor microenvironment would be beneficial for prognosis and therapeutic intervention in CRC. The present study assessed five immunohistochemical EMT markers within the tumor centre on a 185 stage II/III CRC patient TMA...

Chronic inflammation drives colitis-associated colorectal cancer (CAC) in inflammatory bowel disease (IBD). FoxP3+ regulatory T cells (Tregs) co-expressing the Th17-related transcription factor RORγt accumulate in the lamina propria of IBD patients, where they are thought to represent an intermediate stage of development toward a Th17 proinflammatory phenotype. However, the role of these cells in CAC is unknown. RORγt+FoxP3+ cells were investigated in human samples of CAC, and their phenotypic stability and function were investigated in an azoxymethane/dextran sulfate sodium model of CAC using Treg fate mapping reporter and Treg-specific RORγt conditional knockout mice...

AIMS: The lymph node (LN) status is key to determining the need for adjuvant therapy in colorectal cancer and for disease which has progressed to stage II (T3-T4, N0, M0. A LN yield of less than 12 is considered a risk factor similar to high grade histology, vascular, lymphatic and perineural invasion. The object of this retrospective study was to investigate the effect of acetone fat clearance of the mesocolon and mesorectum on LN yield and the identification of high risk stage II CRC patients...

BACKGROUND: The TGFβ-signaling pathway plays an important role in the pathogenesis of colorectal cancer (CRC). Loss of function of several genes within this pathway, such as bone morphogenetic proteins (BMPs) have been seen as key events in CRC progression. METHODS: In this study we comprehensively evaluate differential gene expression (RNASeq) of 81 genes in the TGFβ-signaling pathway and evaluate how dysregulated genes are associated with miRNA expression (Agilent Human miRNA Microarray V19...

AIMS: Oxaliplatin (l-OHP) is a key drug in therapeutic regimens for metastatic or advanced-stage colorectal cancer, but causes peripheral neuropathy as a dose-limiting adverse effect. It is reported that this peripheral neuropathy results from l-OHP accumulation in dorsal root ganglion (DRG) neurons, and that one of the transporters responsible for the accumulation in DRG neurons is organic cation transporter novel (OCTN) 1. Here, we examined whether co-administration of ergothioneine, a substrate/inhibitor of OCTN1, with l-OHP could prevent this peripheral neuropathy...

Circadian clock genes influence biological processes and may be involved in tumorigenesis. We systematically evaluated genetic variants in the circadian clock pathway genes associated with colorectal cancer risk and survival. We evaluated the association of 119 single nucleotide polymorphisms (SNPs) in 27 circadian clock pathway genes with the risk of colorectal cancer in a case-control study (1150 cases and 1342 controls). The false discovery rate (FDR) method was applied to correct for multiple comparisons...

The current study suggests that the identification of predictive signatures of fluorouracil (5-FU) response for stage II and III colorectal cancer (CRC) could be confounded by chemotherapy-irrelevant low relapse risk. Using the samples of patients with stage II and III CRC who were treated with curative surgery only, we identified a signature with which to predict chemotherapy-irrelevant relapse risk for patients after curative surgery. By applying this signature to the samples of patients with stage II and III CRC who were treated with 5-FU-based adjuvant chemotherapy (ACT) after surgery, we predicted the relapse risk if treated with surgery only...

BACKGROUND: Peritoneal carcinomatosis from colorectal cancer is a stage 4 disease for which palliative chemotherapy has traditionally been considered the mainstay of treatment. Since the development of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) by Sugarbaker, this combined method treatment has resulted in improved survival outcomes with acceptable morbidity for selected patients with peritoneal carcinomatosis. This study examined the cost effectiveness of CRS and HIPEC compared with palliative chemotherapy for patients with peritoneal carcinomatosis from colorectal cancer within the context of the Singaporean health care system...
