Specific amplification of tumor specific DNA sequences

摘要

The present invention provides methods for cancer detection and diagnosis. The present invention provides a method of selectively amplifying hypomethylated tumor DNA sequences derived from a subject for detection of cancer. This method utilizes differential methylation to allow for the selective amplification of tumor specific sequences from DNA mixtures that contain a high proportion of normal host DNA. The invention also provides methods of using the amplified tumor DNA sequences for evaluation of methylation.
