BACKGROUND: A right-sided ligamentum teres (RSLT) is a rare congenital anomaly in which the fetal umbilical vein is connected to the right paramedian trunk. RSLT creates difficulty in liver resection with respect to decision-making regarding the resection line, deviation of the vasculobiliary architecture. We report a case in which laparoscopic left lateral sectionectomy (LLLS) was performed to treat colorectal liver metastasis (CRLM) in a patient with RSLT. CASE PRESENTATION: A 63-year-old man with a past history of rectal cancer presented to our institution due to liver metastasis in the left lateral section from rectal cancer...

INTRODUCTION: Metastases represent one of the most outstanding characteristics of malignant neoplasms and are relatively rare in the skin, in spite of the great extension of the cutaneous organs. Development of cutaneous metastases from colon cancer is a rare event, usually occurring in widely disseminated disease and commonly leading to a poor prognosis. As to location, cutaneous metastases often favor areas close to the primary malignancy, such as lung cancer and skin metastases on the trunk...

Protein phosphatase of regenerating liver‑3 (PRL‑3) is considered to be metastasis‑associated phosphatase and is associated with a poor prognosis. Additionally, tumor‑associated macrophages (TAMs) participate in cancer progression. A previous study demonstrated that PRL‑3 promotes invasion and metastasis by inducing TAM infiltration. However, the underlying mechanism has not been elucidated. In the present study, western blot analysis, polymerase chain reaction, immunohistochemistry, ELISA, mouse model experiments and functional experiments were performed to confirm that the interaction between TAMs and colorectal cancer (CRC) cells induced epithelial‑mesenchymal transition (EMT)‑associated features in CRC cells by activating mitogen‑activated protein kinase (MAPK) pathways in TAMs and upregulating the expression of interleukin (IL)‑6 and IL‑8...

The incidence of colorectal cancer liver metastasis (CRLM) has gradually increased in recent years. Surgical resection is the main method to achieve long-term survival for patients with CRLM. However, only 20% of these patients have the chance to undergo surgical resection. If the unresectable metastases can be converted to resectable ones by effective conversion therapy, the 5-year survival rate of patients received liver resection can exceed to 30%, which is significantly better than palliative treatment...

BACKGROUND: Current evidence supporting robotics to perform minimally invasive liver resection is based on single center case series reporting surgical outcomes in heterogeneous groups of patients. On the contrary, relatively scarce data specifically focusing on secondary hepatic malignancies is available. The objective of this study is to assess short- and long-term outcomes following liver resection for colorectal liver metastasis on a multi-institutional series of patients. METHODS: All consecutive patients undergoing robotic surgery for colorectal liver metastasis at three different tertiary hospitals over a 10-year time frame were included in this analysis...

BACKGROUND: Lymph node metastasis (LNM) remains a major obstacle to treat colorectal cancer (CRC). Increasing evidences have suggested that bufadienolides contain several fractions displaying antitumor activity and may be applied in lymphatic chemotherapy. However, effects of the highly efficient and lowly toxic (HELT) bufadienolides on CRC in lymphatic chemotherapy have not been reported. METHODS: Adenosine triphosphate tumor chemosensitivity assays (ATP-TCA) was performed to detect the inhibition rate (IR) of fractions of bufadienolides to cytokine-induced killer (CIK) cells and tumor cells...

Metastasis is a complex process that requires the interaction between tumor cells and their microenvironment. As an important regulator of intestinal microenvironment, gut microbiota plays a significant role in the initiation and progression of colorectal cancer (CRC), but the underlying mechanisms remain elusive. In this study, a metastasis-related secretory protein cathepsin K (CTSK) was identified as a vital mediator between the imbalance of intestinal microbiota and CRC metastasis. We implanted MC38 cells into the cecal mesentry of antibiotic-treated mice with intragastrically administration of E...

OBJECTIVES: Long non-coding RNAs (lncRNAs) consist of a cluster of RNAs having >200 nucleotides lacking protein-coding function. Recent studies indicate that lncRNAs are involved in various cellular processes and their aberrant expression may lead to tumour development and progression. They may also serve as oncogenes or tumour suppressor genes in other diseases. In this review, we emphasize current investigations involving clinical management, tumour progression and the molecular mechanism of SNHG1 in human cancer...

The liver is the most common site of metastatic disease1 . Although this metastatic tropism may reflect the mechanical trapping of circulating tumour cells, liver metastasis is also dependent, at least in part, on the formation of a 'pro-metastatic' niche that supports the spread of tumour cells to the liver2,3 . The mechanisms that direct the formation of this niche are poorly understood. Here we show that hepatocytes coordinate myeloid cell accumulation and fibrosis within the liver and, in doing so, increase the susceptibility of the liver to metastatic seeding and outgrowth...

BACKGROUND: Previously, we aimed to predict the effect of bevacizumab in liver metastasis using the ratio of the computed tomography (CT) value for hepatic metastatic lesions in the arterial phase in contrast-enhanced (CE) CT to that on plain CT. However, there is no report on the relation between the CT contrast effect and microvessel density (MVD) in liver metastasis. PATIENTS AND METHODS: Thirty-two patients who underwent liver resection for metastasis from colorectal cancer (excluding neoadjuvant chemotherapy cases) between April 2006 and October 2011 at our Department were analyzed retrospectively...

PURPOSE OF REVIEW: The aim of this review is to discuss existing data on liver transplantation for colorectal liver metastasis, emerging controversies, and future directions. RECENT FINDINGS: Contemporary experience with transplanting patients with liver metastasis from colon cancer is mainly derived from European centers, with a large proportion being from a single institution (SECA study), made possible in part by a relatively high donor pool. The initial results prove to be encouraging by demonstrating an overall survival advantage over unresectable patients with liver-limited disease managed with chemotherapy only...

Liver metastasis is the commonest form of distant metastasis in colorectal cancer. Selection criteria for surgery and liver-directed therapies have recently been extended. However, resectability remains poorly defined. Tumour biology is increasingly recognized as an important prognostic factor; hence molecular profiling has a growing role in risk stratification and management planning. Surgical resection is the only treatment modality for curative intent. The most appropriate surgical approach is yet to be established...

BACKGROUND: Liver metastases are the major cause of colorectal cancer (CRC)-related deaths. However, there is no reliable clinical predictor for CRC progression to liver metastasis. In this study, we investigated possible predictors (miRNAs and biomarkers) for clinical application. METHODOLOGY: The Gene Expression Omnibus (GEO) datasets GSE49355, GSE41258 and GSE81558 for genes and GSE54088 and GSE56350 for miRNAs were used to identify common differentially expressed genes (DEGs) and miRNAs between primary CRC tissues and liver metastases...

Most patients whose large bowel cancer has spread to other organs do not respond to immune therapy. We detected a rare gene mutation, termed 9p24.1 copy-number gain, in an otherwise incurable colorectal cancer that provoked an immune therapy response. We identified this gene mutation by gene-panel sequencing of DNA from a liver metastasis biopsy from a patient who had disease refractory to standard therapies. Following immune checkpoint blockade with pembrolizumab (anti-PD-1), the patient experienced conversion of the tumor phenotype from one with epithelial features to that of an inflamed microenvironment, detected by high-resolution RNA sequencing...
