摘要
The invention provides a method for diagnosis of, and determining a prognosis for, cancer causatively associated with derangements of chromosome 9p21. Underlying the invention is the discovery that such derangements have their genesis in deletions occurring centromeric to STS 3.21, most often including breakpoints in exon 8 and/or between exons 4 and 5 of the gene which codes for methylthioadenosine phosphorylase. As the cancer and tumor development advance, deletions in 9p21 progress centromerically from the genesis point toward the gene encoding p16. Thus, the method of the invention is performed by determining whether (a) portions of the 9p21 region including and telomeric to STS 3.21 are deleted; and (b) portions of the 9p21 region centromeric to STS 3.21 are deleted; wherein a positive finding in step (a) and a negative finding in step (b) are indicative of a cancer in an early stage of tumor development and a positive finding in step (b) is indicative of a cancer in an advanced stage of tumor development.
