N2 - Comparative genomic hybridization (CGH) was utilized to investigate genetic changes from archived cases of choriocarcinoma (n = 12) and hydatidiform moles (n = 7). Test DNA was extracted from paraffin-embedded tissues, amplified using total universal PCR, and co-hybridized with control DNA to normal metaphases. Comparative genomic hybridization findings showed chromosomal imbalances in 9 of 12 cases of choriocarcinoma. By contrast, all hydatidiform moles showed normal CGH profiles. Consistent findings in choriocarcinoma included deletion at 8p (5 cases) and amplification at 7q (4 cases). A tumor suppressor gene (e.g., N33) at 8p and/or a growth regulator at 7q could play a role in the initiation of choriocarcinoma and its progression. This is the first study showing specific alterations in choriocarcinomas by CGH, and illustrates the utility of this technique in elucidating genetic changes in gynecological tumors.
