Background and Objectives: Involvement of lymph nodes is an important prognostic factor in the most cancers, including colorectal cancer. In the recent years, invasion to blood and lymphatic vessels has been shown to predict involvement of lymph nodes and the number of involved nodes has been less studied issue. The aim of this study was determination of the relationship between the size of col...
Introduction: In recent studies, methylation of FOXE1 in colorectal cancer has been reported as a diagnostic biomarker. In this study for the first time, the expression of FOXE1 and PTCSC2 in colorectal cancer was investigated and their expression patterns in two healthy and tumor tissues of patients were compared. Methods: In this study, 40 tumor tissues with colorectal cancer and 40 adjacent...
BBackground: Despite advances in cancer studies, colorectal cancer, as the third most common cancer, has the highest mortality rate worldwide. Due to its high prevalence in the younger ages and advanced stages, screening of this cancer with molecular methods is necessary. Studies have shown that HOTAIR gene plays an important role in cancers. Our aim in the present study was to determine the...

background: gastric and colorectal adenocarcinoma are the second and the fifth most common cancers in iran, respectively. expression of cytokeratin 7 (ck7) is established in most malignancies including gastric and colorectal adenocarcinoma. demonstration of ck7 could be related to prognostic factors and help to the better management of the patients. the objective of our study was to evaluate th...
objective(s) p53 is an important tumor suppressor, which is mutated in later stages of many cancers and leads to resistance to chemotherapy. the aim of this study was to reveal mutations of tp53 in colorectal cancer in kerman province. materials and methods a total of forty-three colon cancer specimens as paraffin block or fresh tissues, which passed stage iiia, were selected. three exons 5, 7 ...
Background: Colorectal cancer (CRC) is the fourth leading cause of cancer-caused death around the world. Reports of the unnecessary transcription of family genes of the fibroblast growth factor in several types of cancer indicate the role of these factors in tumorgenesis and progression of cancer. Therefore, the level of FGF11 transcription was evaluated in colorectal cancer tumor tissues relat...
Background: Colorectal cancer is the fourth most common cancer in the world. It is the third largest risk factor for cancer individuals. The number of new cases is rising since 1975. Hyper activities of EGFR family have been reported in various cancers. The purpose of this study was to investigate the expression levels of HER2 in colorectal cancer and its possible association with advanced stag...
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...
in a cross-sectional study aiming to investigate the anatomical distribution of colorectal cancer in a six years period, patients file were studied and 150 patients with colorectal cancer were selected based on age, gender, place of residency, place of anatomical tumor and biological symptom. the findings indicated that 91(59.9) of patients had adenocarcinum, 54 (35.5) pulyp and 7 (4.6) had oth...
