Expression profiles for lymph node metastasis in I-III colorectal cancer

ABSTRACT: Lymph node metastasis(LNM) is the most common metastatic pathway of colorectal cancer (CRC), with a rate of 40.5% to 49.7%. Meanwhile, LNM also is one of the most important prognostic risk factor and often predicts a poor clinical outcome. Therefore, it is necessary to identify relevant genes or elucidate potential molecular mechanisms of LNM in order to develop effective prevention and treatment strategies. The aim of this study is to give an insight into the specific signatures and molecular mechanisms of lymph node metastasis in CRC.

microRNA profiles for lymph node metastasis in T1-stage colorectal cancers.

Project description:If we can more accurately predict the likelihood of regional lymph node metastasis (LNM) for endoscopically resected T1-stage colorectal cancers (CRC), the number of unnecessary additional surgeries can be reduced. We aimed of identify miRNA markers that can predict LNM-positive tumors among T1-stage CRCs and we also developed a miRNA classifier set for facilitating the accuracy and applicability.

Different miRNA expression profiles of CRC with or without lymph node metastasis

Project description:Identifying the exact molecules associated with CRC metastasis may be crucial to understand the process, which might also be translated to the diagnosis and treatment of CRC. In this study, we investigate the association of microRNA expression patterns with the lymph node metastasis of colorectal cancer. To investigate the association of microRNA expression patterns with the lymph node metastasis of colorectal cancer, eight primary colorectal cancer tissues derived from stage II–III colorectal cancer patients with (n = 4) or without (n = 4) lymph node metastasis were collected and the miRNA expression profiles of them were determined using Agilent miRNA microarray. Different miRNA expression profiles were identified in CRC tissues between lymph node metastasis positive and negative group.

Plasma protein signatures associated with lymph node metastasis in colorectal cancer

Project description:Currently, the diagnostic accuracy of Lymph node metastasis in CRC is currently unsatisfactory.In the present study, we assembled two cohorts of patients with or without LNM and evaluated the changed plasma proteomic. We developed a high-performance prediction model, which showed superior diagnostic accuracy for predicting LNM in patients suffering from this lethal malignancy.

Lymph Node Metastases in Colon Cancer are Polyclonal

Project description:Recent studies have highlighted the role of sub-clones in tumors. Lymph nodes are generally the first location of metastasis for most solid epithelial tumors including Colorectal cancer (CRC). We sought to understand the genetic origin of lymph node metastasis in CRC by evaluating the relationship between CRC tumor sub-clones and lymph nodes.

Mass spectrometric detection of proteins associated with lymph node metastasis in T1/2 colorectal cancer from FFPE archival specimens

Project description:Surgical resection of colorectal cancers (CRC) that have not invaded beyond the bowel wall (i.e. Stage I) can achieve 5-year patient survival rates exceeding 90%. In the majority of Stage I cases with T1 (submucosal) or T2 (not beyond the muscularis propria) depth of tumour invasion, surgery alone is curative. However, for approximately 10% of resected T1/2 CRC, even though histopathology inspection of the tumour deems it to be restricted to the bowel wall, malignant cells are identified in draining lymph nodes, signifying local metastasis. These patients are classified with Stage IIIA disease and are at greater risk than Stage I patients whose tumours show similar invasive depth, but lack lymph node involvement. To counter the risk of distant malignant dissemination, Stage IIIA patients require more extensive treatment with adjuvant chemotherapy, while Stage I patients do not. In this study we aim to get a better understanding of the underlying biological pathways linked to lymph node metastasis (LNM) using discovery based MS (DIA) and RNASeq as well as IHC and PRM to verify possible protein marker. All of this was done on archival tissue samples (FFPE).

Gene Expression Profiling of Fixed Tissues of Lymph Node Metastasis in Hepatocellular Carcinoma

Project description:RNA was extracted from formalin-fixed specimens of paired intratumoral and peritumoral tissues of patients with lymph node-positive (n=20) or negative (n=20) HCC. A cDNA-mediated annealing, selection, extension, and ligation assay was performed with an array of 502 known cancer-related genes to identify differentially expressed genes in 80 RNA samples. Total RNA was purified from the tissue specimens using the High Pure RNA Paraffin Kit according to the manufacturer’s protocol. DASL experiments were performed to identify genes that were differentially expressed between the lymph node metastasis (LNM) and non-lymph node metastasis (NLNM) groups of matched intratumoral and peritumoral tissues by using A cDNA-mediated annealing, selection, extension, and ligation assay.

Proteomics Characteristics Reveal the Risk of T1 Colorectal Cancer Metastasis to Lymph Nodes

Project description:The presence of lymph node metastasis (LNM) affects treatment strategy decisions in T1NxM0 colorectal cancer (CRC), but the currently used clinicopathological-based risk stratification cannot be used to accurately predict LNM. In this study, we established a model for predicting LNM and explored the mechanism of metastasis in T1 CRC.
