Abstract
e16573 Background: Ephitelial ovarian cancer (EOC) is the leading cause of death from gynecologic malignancies among women worldwide. Little is known about reproductive factors or lifestyle determinants and ovarian cancer prognosis. The purpose of this study was to analyze the pathologic, clinical and other characteristics. Methods: This study included all EOC seen at the Institute from 2000–2006. Epidemiological and clinical variables were collected from the patients’ medical records. Exposure data on prediagnostic factors were collected through questionnaires. The cases were followed-up until December 31, 2007. Cox proportional hazard regression model was used to estimate the prognostic effect of each factor in terms of hazard ratios (HR) and 95% confidence intervals (CI), following adjustment for age at diagnosis, FIGO tumor stage and WHO grade of tumor differentiation. Results: 571 cases of ovarian cancers. Median age was 51 years, (range 18–95). 20.30%, 4.4%, and 63.5% of patients had stage I, II and III, respectively. The histological types: 52.2% serous, 17.2% endometrioid, 12.8% of mucinous origin; 62.5% underwent radical surgery, 24% with optimal cytorreduction. The mean follow-up was 60 ± 22 months. The overall three-year survival was 97.4% and 98% for mucinous and serous tumors, respectively. The survival rate was 100%, 90%, and 71.8% in stages I, II and III, respectively. After adjustment for the tumor characteristics, no clear associations were detected between reproductive history, anthropometric characteristics, factors before diagnosis (alcohol consumption, smoking and physical activity over lifetime), nor family history of breast cancer or ovarian cancer and survival Conclusions: Our findings indicate that the tumor characteristics significantly influenced the risk of death from ovarian cancer and no clear associations were detected between others factors and the survival. In this cohort the median age for ovarian cancer were 51 years old, one decade before than other reports. No significant financial relationships to disclose.
