Purposes: The objectives of this study were to investigate the prevalence of
HER-2/neu oncogene amplification by differential polymerase chain reaction and to
examine whether HER-2/neu oncogene overamplification has any prognostic significance
in advanced epithelial ovarial cancer patients.
Materials and Methods: The study population comprised thirty patients with stage III
or IV epithelial ovarian cancer who were managed at Asan Medical Center between
January 1994 and December 1996. Fresh frozen tumor samples of primary lesion were
analysed by differential polymerase chain reaction to assess amplification of HER-2/neu
oncogene. The correlation between HER-2/neu oncogene overamplification and histologic
subtype or tumor grade or serum CA 125 level after second chemotherapy were
evaluated using chi-square test, and for survival analysis, Kaplan-Meier curves were
plotted and the differences between the curves were tested for significance using
Log-rank test.
Results: HER-2/neu oncogene was amplified in all of the cases (100% 30/30), but
significant overamplification[gene copy number ¡Ã 1.5 a.u.(arbitrary unit)] was observed
in 46.7% (14/30). There was no significant correlation between HER-2/neu oncogene
overamplification and histologic subtype or tumor grade or serum CA 125 level after
second chemotherapy and there was no correlation between HER-2/neu oncogene
overamplification and overall survival.
Conclusion: The prevalence of HER-2/neu oncogene overamplification is 46.7%, but it
may not be a significant prognostic factor in advanced epithelial ovarian cancers.
