Feasibility of CTCs Isolation for Transcriptomes and Genome Wide Associated Analysis in Post-OP High Risk OSCC Patients.

Anti-cancer treatments have been thought to be closely related to their unique genetic alterations. In the past few years, the investigator have used cDNA microarray to delineate the transcriptome profiles of differentially-expressed genes between OSCC tumors and normal epithelium. By supervised hierarachical clustering analysis, the investigator further analyzed and validated the differentially-expressed genes for OSCC tumors. In the investigators' previous research, the investigators have used this strategy to analyze the potential tissue proteins associated with OSCC tumors, indicating the feasibility of this strategy. However, gene detection is a great limitation and challenge in CTCs researches owing to the small number of isolated cells by traditional methods. Fortunately, by means of the investigators' developing high-purity CTCs isolation techniques, some preliminary data implied that isolated CTCs by this method could achieve the criteria of Whole-genome analysis (WGA), which brings the investigators' passion for further investigation.
