The invention provides methods, nucleic acids and kits for determining the prognosis of a subject having cell proliferative disorder, preferably cancer. The invention discloses genomic sequences the methylation patterns of which have utility for the improved detection of said disorder, thereby enabling the improved diagnosis and treatment of patients.

Methods and nucleic acids for analyses of cell proliferative disorders

Particular aspects relate to a method for determining the methylation pattern of a polynucleic acid, comprising: a) preparing a solution comprising a mixture of fragments of the polynucleic acid; b) coupling the fragments with a substance being detectable with a detection method; c) contacting a solution comprising the fragments of b) with a DNA microarray having a plurality of different immobilized oligonucleotides, each comprising at least one methylation site, at respectively assigned different locations thereon, the contacting under conditions affording hybridization of fragments with correlated immobilized oligonucleotides under defined stringency, and wherein the immobilized oligonucleotides have a length of less than 200 bases; d) optionally performing a a washing step; and e) detecting, using the physical detection method, such immobilized nucleic acids to which solution fragments are hybridized and/or to which solution fragments are not hybridized.
