    Abstract

    It has been suggested that paracetamol reduces the risk for ovarian cancer. We examined the association between prescription use of paracetamol and ovarian cancer risk in a nationwide case-control study nested within the Danish female population. Case patients (n = 3471) were all women with a first diagnosis of epithelial ovarian cancer during the period from 2000 to 2009. Population control subjects (n = 50576) were selected by risk set sampling. Data were derived from prescription and other nationwide registries. Conditional logistic regression was used to estimate odds ratios (ORs) and two-sided 95% confidence intervals (CIs) for ovarian cancer associated with use of paracetamol or nonaspirin nonsteroidal anti-inflammatory drugs (NSAIDs). All statistical tests were two-sided. Use of paracetamol was associated with a reduced odds ratio for ovarian cancer (OR = 0.82; 95% CI = 0.74 to 0.92; P < .001) compared with nonuse, and the odds ratio decreased further with long-term (≥10 years), high-intensity paracetamol use (OR = 0.45; 95% CI = 0.24 to 0.86; P = .02). Use of nonaspirin NSAIDs was not associated with ovarian cancer risk.
