Gene expression signature and the prediction of recurrence in stage III colorectal cancer by DNA microarray

ABSTRACT: Samples were taken from colorectal cancers in surgically resected specimens in 36 colorectal cancer patients. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for molecular markers for predicting recurrence. Keywords: repeat

Gene expression signature and the prediction of recurrence in stage III colorectal cancer by DNA microarray

Project description:Samples were taken from colorectal cancers in surgically resected specimens in 36 colorectal cancer patients. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for molecular markers for predicting recurrence. Keywords: repeat Thirty-six colorectal cancer patients who had undergone surgical resection of colorectal cancer were studied. In all patients, curative resection was performed and no patients had any distant metastasis at the time of operation (stage III patients). Among the 36 patients, 23 patients did not develop recurrence. On the other hand, 13 patients developed rucurrence such as liver metastases, lung metastases and distant lymph node metastases. The median follow up period was 4.5 years.

Gene expression signature and the prediction of liver metastasis in colorectal cancer by DNA microarray

Project description:Samples were taken from colorectal cancers in surgically resected specimens in 189 colorectal cancer patients. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for molecular markers for predicting liver metastasis. Keywords: repeat One hundred and eighty nine patients who underwent surgical resection of colorectal cancer were included in this study. Patients were evaluated at 3-month intervals for the first postoperative year and at 6-month intervals thereafter. Liver metastases were identified by clinical and laboratory examination, completed by liver ultrasound or CT scan. Patients were divided randomly into a training and a validation set. A training set consisted of 160 patients, while a test set 29 patients.

A new classification of chromosome instability (CIN) phynotype, CIN-high and CIN-low (validation dataset)

Project description:Samples were taken from colorectal cancers in surgically resected specimens in 33 colorectal cancer patients. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for molecular markers for CIN phynotype

A new classification of chromosome instability (CIN) phenotype, CIN-high and CIN-low

Project description:Samples were taken from colorectal cancers in surgically resected specimens in 35 colorectal cancer patients. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for molecular markers for CIN phynotype.

Gene expression signature of colorectal cancer with microsatellite instability.

Project description:Samples were taken from colorectal cancers in surgically resected specimens in 84 colorectal cancer patients. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes between MSI and MSS cancers and, furthermore, to determine the distinct characteristics of proximal and distal MSI cancers. Keywords: repeat

Molecular Marker for predicting development of cancer in ulcerative colitis

Project description:Samples were taken from either surgically resected specimens or during surveillance colonoscopic examination. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for molecular markers for predicting development of cancer and/or dysplasia in ulcerative colitis, and to characterize potential diagnostic markers in UC-associated neoplasm. Keywords: repeat
