Abstract
BACKGROUND: Ovarian cancer is usually a cancer of the older age group. Comorbidities and comedications increase with rising age. Aim of this study was to evaluate association of comorbidity and comedication with grade III/IV toxicities and prior cessation of chemotherapy in ovarian cancer patients. PATIENTS AND METHODS: As an individual participant data meta-analysis this study analyzes the original data of three phase II/III chemotherapy studies of the North-Eastern German Society of Gynecological Oncology (NOGGO). Risk scores for certain combinations of risk factors were calculated based on stepwise regression analyses. RESULTS: Altogether, 1213 patients were included in the study. Cardiovascular disease was the most frequent comorbidity (47.5%). In multivariate analyses it was associated with hematological, non-hematological, pulmonary and renal grade III/IV toxicities (p=0.002; p<0.001; p=0.005; p<0.001). Renal toxicity was more frequent when using diuretics and ACE-inhibitors (p<0.001; p=0.002). Prior cessation of therapy was e.g. associated with use of diuretics, insulin and digitalis (p=0.001; p=0.04; p=0.03). The risk for renal grade III/IV toxicities was more than 16 times higher when using both a diuretic and an ACE-inhibitor. CONCLUSIONS: Regimens of ovarian cancer treatment should not be restricted to direct cancer therapy but rather include additional individualized treatment of comorbidities. Comedications such as diuretics increase grade III/IV toxicities and patients at risk should be closely monitored.
