The Application of Gene Expression Profiling in Predictions of Occult Lymph Node Metastasis in Colorectal Cancer Patients

چکیده
A key factor in determining the likely outcome for a patient with colorectal cancer is whether or not the tumour has metastasised to the lymph nodes-information which is also important in assessing any possibilities of lymph node resection so as to improve survival. In this review we perform a wide-range assessment of literature relating to recent developments in gene expression profiling (GEP) of the primary tumour, to determine their utility in assessing node status. A set of characteristic genes seems to be involved in the prediction of lymph node metastasis (LNM) in colorectal patients. Hence, GEP is applicable in personalised/individualised/tailored therapies and provides insights into developing novel therapeutic targets. Not only is GEP useful in prediction of LNM, but it also allows classification based on differences such as sample size, target gene expression, and examination method.

DETERMINATION OF THE PREVALENCE OF OCCULT NECK LYMPH NODE INVOLVEMENT IN PATIENTS WITH LARYNGEAL SQUAMOUS CELL CARCINOMA
Background & Aims: Squamous cell carcinoma (SCC) accounts for 85% of laryngeal cancers. In some cases, lymph nodes do not show any specific symptoms despite being involved by cancer. Previous studies showed that patients undergoing selective neck lymph node dissection (SND) had significantly lower recurrence rates. We investigated the prevalence of occult neck lymph node involvement in patients...

Emerging evidence implicates that a large fraction of human genome was transcribed but the transcripts known as long non coding RNA are not translated into proteins. They are contributing in different cellular processes, including cellular proliferation and apoptosis. LncRNAs were found to play critical roles in many diseases and act as key regulators in malignancies. In this study, we investig...

Background & Objective: Recent studies from gene profiling have revealed some genes that are overexpressed in the epithelial-mesenchymal transition (EMT) process and are responsible for its initiation and activation resulting in tumor progression and metastasis. The present study aimed to assess the role of genes involved in the EMT process and the association of these genes wi...

متن کاملMLH1 Gene Expression and Pathologic Factors in Iranian Patients with Colorectal Cancer
Background and Objectives: MutL homolog (MLH1) is a key component of heterodimeric complex MutLα, which recognizes and repairs base-base mismatches or insertion/deletion loops that arise from nucleotide misincorporation. In the absence of MLH1 protein, the number of unrepaired mismatches will increase and cause tumors in organs. The present study aimed at quantitative analysis of MLH1 gene expr...
