Integrative analysis of genomic aberrations in the context of trancriptomic alterations will lead to a more comprehensive perspective on prostate cancer progression. Genome-wide copy number changes were monitored using array comparative genomic hybridization of laser-capture microdissected prostate cancer samples spanning stages of prostate cancer progression, including precursor lesions, clinically localized disease, and metastatic disease. A total of 62 specific cell populations from 38 patients were profiled. Minimal common regions (MCR) of alterations were defined for each sample type, and metastatic samples displayed the most number of alterations. Clinically localized prostate cancer samples with high Gleason grade resembled metastatic samples with respect to the size of altered regions and number of affected genes. A total of 9 out of 13 MCRs in the putative precursor lesion, high-grade prostatic intraepithelial neoplasia (PIN), showed an overlap with prostate cancer cases (amplifications in 3q29, 5q31.3-q32, 6q27, and 8q24.3 and deletions in 6q22.31, 16p12.2, 17q21.2, and 17q21.31), whereas postatrophic hyperplasia (PAH) did not exhibit this overlap. Interestingly, prostate cancers that do not overexpress ETS family members (i.e., gene fusion-negative prostate cancers) harbor differential aberrations in 1q23, 6q16, 6q21, 10q23, and 10q24. Integrative analysis with matched mRNA profiles identified genetic alterations in several proposed candidate genes implicated in prostate cancer progression.
