However, we were not able to detect any chromosomal imbalance in the DD samples. The method used was Oligonucleotide aCGH Agilent's 60-mer oligonucleotide-based microarray according to the manufacturer's instructions, which can reveal gains and losses of approximately 35 kilobases in the whole genome. The result does not exclude copy number changes entirely; a small presence of aberrant cells will not be detected if the change is less than 50%.In conclusion, we revealed elements in DD tissue that would enable us to predict the nature of the disease; whether the disease is aggressive with a stronger tendency to recur. Histological differences could be detected, and this can be used to benefit patients. As a new element, ROR2 was discovered in DD tissue.The genome-wide analysis with the 44K oligonucleotide-based array method revealed no changes of DNA number sequences.
