Women aged 20 and above, diagnosed with advanced stage ovarian cancer (FIGO stage II\~IV), who had received debulking surgery, followed by adjuvant chemotherapy (either dose-dense or intraperitoneal) at our institution between 01 January 2006 and 31 December 2018 were included in the study. Patient characteristics, any treatment related side-effects (peri-operative and post-operative complications, chemotherapy related adverse events), treatment response (complete or partial response, stable disease or progressive disease), post-treatment surveillance (disease status: disease-free, recurrence or cancer-related death) will be recorded. Univariate and multivariate logistic regression analysis will be employed to evaluate the survival benefit of the two different chemotherapy methods.
