This book was released on 1999 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates evidence for an increased risk of cancer in women using combined oral contraceptives, progestogen-only hormonal contraceptives, post-menopausal estrogen therapy, and post-menopausal estrogen-progestogen therapy. Although the carcinogenicity of these preparations has been extensively investigated, the book stresses the many complex methodological issues that must be considered when interpreting findings and weighing results. Evidence of an association between use of these preparations and positive effects on health, including a reduced risk of some cancers, is also critically assessed. The first and most extensive monograph evaluates evidence of an association between the use of combined oral contraceptives and cancer at nine sites. Concerning breast cancer, the evaluation concludes that, even if the association is causal, the excess risk for breast cancer associated with patterns of use that are typical today is very small. Studies of predominantly high-dose preparations found an increased risk of hepatocellular carcinoma in the absence of hepatitis viruses. Citing these findings, the evaluation concludes that there is sufficient evidence in humans for the carcinogenicity of combined oral contraceptives. The evaluation also found sufficient evidence for the carcinogenicity of some, but not all, combined preparations in animals. Combined oral contraceptives were classified as carcinogenic to humans. The evaluation also cites conclusive evidence that these agents have a protective effect against cancers of the ovary and endometrium. Progestogen-only contraceptives are evaluated in the second monograph, which considers the association with cancer at six sites. The evaluation found no evidence of an increased risk for breast cancer. Although the evaluation found sufficient evidence in animals for the carcinogenicity of medroxyprogesterone acetate, evidence for the carcinogenicity of progestogen-only contraceptives in humans was judged inadequate. Progestogen-only contraceptives were classified as possibly carcinogenic to humans. The third monograph, on post-menopausal estrogen therapy, considers evidence of an association with cancer at eight sites. Findings from a large number of epidemiological studies indicate a small increase in the risk of breast cancer in women who have used these preparations for five years or more. Studies consistently show an association between use of post-menopausal estrogen therapy and an increased risk for endometrial cancer. Data on the association with other cancers were either inconclusive or suggested no effect on risk. The evaluation concludes that post-menopausal estrogen therapy is carcinogenic to humans. The final monograph evaluates the association between the use of post-menopausal estrogen-progestogen therapy and cancer at four sites. The evaluation of limited data on breast cancer found an increased relative risk observed with long-term use. Data were judged insufficient to assess the effects of past use and of different progestogen compounds, doses, and treatment schedules. For endometrial cancer, the evaluation found an increase in risk relative to non-users when the progestogen was added to the cycle for 10 days or fewer. Post-menopausal estrogen-progestogen therapy was classified as possibly carcinogenic to humans. Concerning post-menopausal therapy in general, the book notes that evidence of carcinogenic risks must be placed in perspective of potential benefits. The prevention of osteoporotic fractures is cited as the best-established benefit. Evidence also suggests that estrogen prevents heart disease and may prevent memory loss and dementia.

Book excerpt: The first oral contraceptive became available in 1960 and since then these sub stances, which have been used by millions of women, have probably been the most widely studied group of drugs in medical history (Drill, 1966, 1977). Part of the evaluation oCoral contraceptives has involved their effect on the reproductive organs of women, with particular attention directed to evaluation of a possible carcinogenic effect of these steroids. To the extent that cancer of the reproductive organs is a common finding in women, the endogenous female sex hormones have been implicated in the occur rence of the cancer. The administration of estrogen has also been reported to in crease the incidence of cancer of the breast, cervix or endometrium in some strains or species of animals. Thus, because of the possible tumorigenic effect of estrogens there has been considerable interest in the relationship of oral contraceptives to cancer of the breast and genital tract.

This book was released on 2004-04-12 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than a quarter of pregnancies worldwide are unintended. Between 1995 and 2000, nearly 700,000 women died and many more experienced illness, injury, and disability as a result of unintended pregnancy. Children born from unplanned conception are at greater risk of low birth weight, of being abused, and of not receiving sufficient resources for healthy development. A wider range of contraceptive options is needed to address the changing needs of the populations of the world across the reproductive life cycle, but this unmet need has not been a major priority of the research community and pharmaceutical industry. New Frontiers in Contraceptive Research: A Blueprint for Action, a new report from the Institute of Medicine of the National Academies, identifies priority areas for research to develop new contraceptives. The report highlights new technologies and approaches to biomedical research, including genomics and proteomics, which hold particular promise for developing new products. It also identifies impediments to drug development that must be addressed. Research sponsors, both public and private, will find topics of interest among the recommendations, which are diverse but interconnected and important for improving the range of contraceptive products, their efficacy, and their acceptability.
