abstract

  • Insulin-like growth factor binding protein-3 (IGFBP-3) regulates the mitogenic and anti-apoptotic actions of insulin-like growth factors (IGFs). To study the role of IGFBP-3 in ovarian cancer progression, we measured IGFBP-3 concentrations in tumour tissues from 147 patients with epithelial ovarian carcinoma and examined its associations with clinicopathological features of disease and patient survival. The average age of the patients was 54.6 years (range 25-88 years) and the median follow-up time was 37 months. IGFBP-3 levels were measured with a commercial immunoassay kit. Low IGFBP-3 levels were significantly associated with unfavourable prognostic features of the disease, including advanced stage (P=0.048), large size of residual tumour (P=0.007), and suboptimal debulking outcome (P=0.007). Low IGFBP-3 levels were also associated with a significantly increased risk for disease progression (RR=1.92; 95% confidence interval (CI) 1.05-3.45; P=0.034), but the association was not sustained when other clinical and pathological variables were adjusted for in the analysis. No significant associations were observed between the IGFBP-3 level and patients' overall survival and response to chemotherapy. Findings of the study indicate that IGFBP-3 may play a role in the progression of epithelial ovarian cancer, but that it has no independent value in predicting either disease prognosis or the response of patients to chemotherapy.
