BACKGROUND: Several oncogenes and onco-suppressor genes have been implicated in epithelial ovarian carcinogenesis, but their clinical significance is not clear and conflicting data have been found in various studies. PATIENTS AND METHODS: The immunohistochemical expression of HER-2, p53 and Bcl-2 proteins was investigated in a cohort of 95 patients with advanced epithelial ovarian cancer (stages IIc-IV). These patients participated in a phase III randomized clinical trial and were treated either with paclitaxel/carboplatin, orpaclitaxel/carboplatin alternating with paclitaxel/cisplatin. RESULTS:Positive immunostaining for HER-2, p53 and Bcl-2 proteins was found in 18%, 70.5% and 69.5% of the cases, respectively. In multivariate analysis, older patients (< 63 vs. > or = 63 years, p < 0.001), worse grade (I-II vs. III, p = 0.04) and p53 expression (negative vs. positive, p = 0.002) were significant prognostic factors independently associated with survival. CONCLUSION: p53 status along with age and grade appear to be independent prognostic factors for survival in patients with epithelial ovarian cancer.
