Use of analgesic drugs and risk of ovarian cancer-Results from a Danish case-control study.
Summary of "Use of analgesic drugs and risk of ovarian cancer-Results from a Danish case-control study."
Objective. The role of analgesic drug use in ovarian cancer development is not fully understood. We examined the association between analgesic use and risk of ovarian cancer. In addition, we examined whether the association differed according to histological types. Design. Population-based case-control study. Setting. Denmark in the period 1995-1999. Population. We included 756 women with epithelial ovarian cancer and 1564 randomly selected controls aged 35-79 years. Methods. Information on analgesic drug use was collected from personal interviews. Analgesic drugs were divided into the following categories: any analgesics, aspirin, non-aspirin non-steroidal anti-inflammatory drugs, paracetamol, and other analgesic drugs. The association between analgesic drug use and ovarian cancer risk was analyzed using multiple logistic regression models. Odds ratios (OR) and 95% confidence intervals (CI) were estimated. Main outcome measures. Epithelial ovarian cancer. Results. Women with a regular use of any analgesics (OR = 0.79; 95%
0.62 - 1.01) and aspirin (OR = 0.68; 95%
0.46 - 1.02) had a decreased risk of ovarian cancer, although not statistically significant. Regular use of non-aspirin non-steroidal anti-inflammatory drugs, paracetamol, and other analgesics did not decrease ovarian cancer risk. Use of any analgesics (OR = 0.72; 95%
0.53-0.98) and aspirin (OR = 0.60; 95%
0.36-1.00) resulted in a statistically significant decreased risk of serous ovarian cancer but not mucinous or other ovarian tumors. Conclusion. In accordance with most previous studies our results indicate a possible inverse association between analgesic use, particularly aspirin, and ovarian cancer risk.

Medical and Biotech [MESH] Definitions
A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions. (From National Cancer Institute, NIH Publication No. 91-3074, October 1990)
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Hamartoma Syndrome, Multiple
A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
The science concerned with the benefit and risk of drugs used in populations and the analysis of the outcomes of drug therapies. Pharmacoepidemiologic data come from both clinical trials and epidemiological studies with emphasis on methods for the detection and evaluation of drug-related adverse effects, assessment of risk vs benefit ratios in drug therapy, patterns of drug utilization, the cost-effectiveness of specific drugs, methodology of postmarketing surveillance, and the relation between pharmacoepidemiology and the formulation and interpretation of regulatory guidelines.
