Association of MSI, TS, DPD, MVD and EGFR With Chemosensitivity in Stage IV in Colorectal Cancer

ABSTRACT: The present project will follow our previous phaseⅡ study of FOLFOX regimens for the treatment of stage Ⅳ colorectal cancer. We will recruit at least 200 patients for this study. The selection of patients will be based on rigorous eligibility criteria. The patients will be allocated based on the expression of each molecular marker (MSI, TS, DPD, MVD and EGFR) and the implementation of chemotherapy. For example, in the examination for the clinical implications of EGFR, the patients will be classified into four groups: EGFR（＋） chemotherapy（＋）; EGFR（＋） chemotherapy（-）; EGFR（-） chemotherapy（＋）; EGFR（-） chemotherapy（-）. Base on the analysis of this 2×2 table, we will clarify the prognostic significance of a specific molecular marker is due to whether the specific molecular marker predicts biological invasiveness and/or chemosensitivity. We believe the present study will have the following significance: （1）To further clarify the mechanisms for the carcinogenesis and progression of CRC; （2）To facilitate the development of novel chemotherapeutic agents; and （3） To gain the experience for the practice of evidence-based medicine.

Project description:OBJECTIVE: To investigate the differentially expressed genes related to the chemosensitivity of laryngeal squamous cell carcinoma ï¼LSCCï¼by microarrays arrays. METHODS: 1. A total number of 11 patients who underwent induction chemotherapy for primary hypopharyngeal squamous cell carcinoma (7 patients are sensitive to chemotherapy ,and others are not) were recruited for microarray and miRNA array gene expression analysis 2. Bioinformatics analysis of differentially expressed genes screened by microarrays : The differential gene cluster analysis was applied in biological processes, cellular components and molecular functions by GO database; The differential gene enrichment analysis was applied in signaling pathways by KEGG database, and the differentially expressed and biologically meaningful core genes would be screened. RESULTS: 1. Analyzed by microarrays, there were 1554 genes significantly related to the sensitivity to chemotherapy; Among these 1554genes, 777 showed a higher expression in the tissue from patients who are sensitive to chemotherapy , while 785 presented the contrasting pattern. CONCLUSIONS: The research revealed a gene expression signature of chemosensitivity in laryngeal squamous cell carcinoma by microarrays arrays. The result will contribute to the understanding of the molecular basis of laryngeal squamous cell carcinoma and help to improve diagnosis and treatment. 1.
