Abstract: Provided herein are, inter alia, methods of detecting DNA methylation levels in patients at risk of developing a gastrointestinal cancer, methods of diagnosing a patient with a gastrointestinal cancer based on DNA methylation levels, methods of monitoring DNA methylation levels in patients at risk of developing a gastrointestinal cancer, and methods of treating patients having a gastrointestinal cancer.

Abstract: A kit for diagnosing gastric cancer in a patient, the kit including nucleic acid probes for detecting elevated levels of expression of a group of micro RNA molecules in a biological sample from the patient. The group of micro RNA molecules consists of miR-18a, miR-21, miR-181a, miR-181b, miR-196a, miR-196b, and miR-146b. The elevated levels of expression are relative to the expression level of a same group of micro RNA molecules in a control biological sample.

Abstract: Dysregulated expression of microRNAs (miRNAs) has emerged as a hallmark feature in human cancers. Aspects of the disclosure relate to methods for selecting optimal therapy for a patient from several alternative treatment options. A major clinical challenge in cancer treatment is to identify the subset of patients who will benefit from a therapeutic regimen, both in metastatic and adjuvant settings. The number of anti-cancer drugs and multi-drug combinations has increased substantially in the past decade, however, treatments continue to be applied empirically using a trial-and-error approach. Here methods and compositions are provided to determine the optimal treatment option for gastric cancer patients.

Abstract: Certain embodiments provide methods and compositions related to clinical management of cancer patients based on the expression level of TMCO3. Further embodiments involve methods and compositions related to treatment of cancer patients or patients determined to have an increased TMCO3 level relative to a control or a reference level that is normal or indicating favorable prognosis.

Abstract: The present invention includes methods and biomarkers for diagnosing or detecting colorectal cancer metastasis in a human subject by comparing the Alu repeat methylation level in the biological sample to an Alu repeat methylation control level from a normal non-cancerous sample from the human subject, wherein a decrease in the Alu repeat methylation level is indicative of colorectal cancer and colorectal cancer metastasis.

Abstract: Embodiments provide methods and compositions related to determining treatments for colorectal cancer patients by detection and analysis of the expression level of miRNA such as miR-320e in the patients.

Abstract: The current disclosure relates to therapeutic treatments and diagnostic methods for esophageal cancer based on the expression level of biomarker miRNAs.

Abstract: Embodiments provide methods and compositions related to determining treatments for colorectal cancer patients by detection and analysis of the expression level of miRNA such as miR-320e in the patients. Embodiments provide predictive, prognostic and/or diagnostics methods by identifying miRNAs that are useful for clinical management of cancer patients, particularly colorectal cancer patients or patients at risk or determined to have colorectal cancer. Methods and compositions are based, in part, on the discovery that expression of certain miRNAs in cancer patients is associated with advancing cancer stages and/or can predict the responsiveness of cancer therapy, and can, therefore, provide basis for designing treatment strategies. In particular embodiments, the miRNA molecule is miR-320, particularly miR-320e.

Abstract: Embodiments provide methods and compositions related to detecting neoplasia in ulcerative colitis patients by detection and analysis of the methylation state of miR-1, -9, -124, miR-137 and/or miR-34b/c in samples from UC patients.

Abstract: The present invention relates to the field of cancer. More specifically, the present invention relates to the use of biomarkers to detect colorectal cancer. In one aspect, the present invention provides methods for qualifying colorectal cancer status including, but not limited to, diagnosis, prognosis, and risk stratification, in patients. In one embodiment, a method for diagnosing colorectal cancer (CRC) in a patient comprises the steps of (a) collecting a sample from the patient; (b) measuring the methylation levels of one or more biomarkers in the sample collected from the patient; and (c) comparing the methylation levels of the one or more biomarkers with predefined methylation levels of the same biomarkers that correlate to a patient having CRC and predefined methylation levels of the same biomarkers that correlate to a patient not having CRC, wherein a correlation to one of the predefined methylation levels provides the diagnosis.

Abstract: Methods and compositions for the diagnosis, prognosis and classification of cancer, especially colorectal cancer, are provided. For example, in certain aspects methods for cancer prognosis using expression or methylation analysis of selected biomarkers are described. Particular aspects of the present invention may include methods and biomarkers for diagnosing or detecting colorectal cancer or metastasis in a subject by measuring a level of expression of biomarker miRNA such as miR-885-5p in the sample from the subject and evaluating the risk of developing cancer or metastasis in the subject.
