Abstract

- Fifteen primary liver carcinomas (PLCs), including 12 hepatocellular carcinomas and three cholangiocellular carcinomas, were investigated cytogenetically after short-term culture. Ten tumors displayed clonal chromosomal abnormalities, whereas only normal karyotypes were detected in four cases, and one sample failed to grow in vitro. Structural rearrangements most often involved chromosomes 1, 7, and 8 and chromosome bands 1p36, 1q25, 3q10, 5q13, 6p10, 7p15, 7q22, 7q32, 8q10, 8q13, 14q10, and 17p11. Frequent genomic imbalances included gains of 1q, 3q, 6p, 7p, and 8q and losses of 1p, 8p, 10q, 14p, 17p, and 19p. A compilation of findings for all 19 cytogenetically abnormal PLCs reported to date, including the present cases, reveals that structural aberrations particularly affect 1p11, 1p22, 1p32, 1p34, 1p36, 1q25, 7p15, 7q22, 8q10, 8q13, 14q10, 16q24, and 17p11, and that the abnormalities frequently result in overrepresentation of 1q, 3q, 6p, 7p10-14, 8q, and 17q and underrepresentation of 1p34-36, 6q27, 7q32-qter, 8p, 13p, 14p, 16q24, and 17p. These genomic regions are likely to harbor genes of importance in hepatocarcinogenesis, and the present cytogenetic mapping may hence be of value for further molecular genetic investigations of PLC.
