To search for recurrent and specific genomic alterations in human hepatocellular carcinoma (HCC), we examined 18 cell lines by comparative genomic hybridization (CGH), a molecular cytogenetic approach that allows positional identification of gains and losses of DNA sequences of the entire tumor genome. We report here a distinct pattern of multiple recurrent DNA copy-number gains and losses that include alterations frequently seen in other neoplasias as well as changes potentially specific for HCC. The most frequent gains were localized on 1p34.3-35, 1p33-34.1, 1q21-23, 1q31-32, 6p11-12, 7p21, 7q11.2, 8q24.1-24.2, 11q11-13, 12q11-13, 12q23, 17q11. 2-21, 17q23-24, and 20p11.1-q13.2. Recurrent losses were mapped on 3p12-14, 3q25, 4p12-14, 4q13-34, 5q21, 6q25-26, 8p11.2-23, 9p12-24, 11q23-24, 13q12-33, 14q12-13, 15q25-26, 18q11.2-22.2, and 21q21-22. Seventeen genomic imbalances are novel in HCC, thus extending significantly the map of genetic changes and providing a starting point for the isolation of new genes relevant in pathogenesis of liver neoplasia, as well as providing molecular probes for both diagnosis and monitoring treatment of the disease.
