Testosterone treatment is controversial for men and even more so for women. Although long-term outcome data are not available, prescriptions for testosterone are becoming more common. Testosterone is used primarily to treat symptoms of sexual dysfunction in men and women and hot flashes in women. Potential benefits include improved libido, increased bone mass, and increased sense of well-being. In individuals with human immunodeficiency virus infection or other chronic diseases, testosterone has been shown to improve mood and energy levels, even in patients with normal testosterone levels. Testosterone can be administered by injection, patch, topical gel, pill, or implant. Side effects in men include polycythemia and acne. Side effects in women include acne, hepatotoxicity, and virilization and usually only occur when testosterone is used in supraphysiologic doses. Long-term studies of the effects of testosterone on prostate cancer, breast cancer, and heart disease have not been completed. Mammograms and monitoring of prostate-specific antigen, hematocrit, and lipid levels are recommended for patients taking testosterone.

The international soy symposium held in Tokyo, November 9-12, 2008, was the eighth in a series that began in 1994. This most recent meeting is noteworthy for several reasons. First, it was held in the country most identified with the foods that are the focus of the meeting. Soyfoods were first consumed in China more than a millennium ago, but it is the low incidence of breast and prostate cancer, heart disease, and hot flashes in Japan, despite the high socioeconomic status of this country, that helped fuel interest in the early 1990s in the possible chronic disease-preventive properties of soy and certain soybean constituents. Second, it was the first time an entire session was devoted to equol, a bacterially derived product of the soybean isoflavone daidzein, which is produced by only approximately 30% of Westerners and has been proposed to be an especially beneficial compound, i.e., the equol hypothesis. And third, there was greater emphasis during this meeting than at past ones on addressing some of the more hotly debated health effects linked with soy intake. The conference was attended by >250 scientists from 20 countries; there were 33 oral and 40 poster presentations during the 4-d event. The majority of presentations at the Tokyo symposium focused on isoflavones. In this article, the major findings presented at the symposium are highlighted, and commentary about those findings and related background is provided.

We retrospectively studied BRCA carriers with a history of prophylactic bilateral salingo-oophorectomy (PBSO) regarding: (1) their post-operative symptoms, (2) their recollection of pre-operative conversations with their health care providers regarding possible surgical side-effects and (3) what information they would have found helpful to have before surgery. Female BRCA carriers seen through the Yale Cancer Genetic Counseling Program who had PBSO were invited to participate in a questionnaire that assessed their recall of information they received pre-operatively compared with their post-operative knowledge and symptoms related to menopause, cognitive changes, loss of fertility, cancer risks, osteoporosis, heart disease, vasomotor symptoms, urogenital symptoms, sexuality and body image. The questionnaire also elicited written feedback from participants regarding their decision to have PBSO, what they wished they had known before surgery, advice for other BRCA carriers considering this surgery and advice for health care providers who counsel women about PBSO. Two hundred and ninety female BRCA carriers were invited to participate and 113 (39.0%) indicated they were interested. Of those, 99 (87.6%) returned their questionnaire and 98 (86.7%) responses were included in the analysis. The mean age at PBSO was 45.5 years (range: 32-63 years). The five most common "frequent" or "very frequent" post-surgical symptoms were: vaginal dryness (52.1%), changes in interest in sex (50.0%), sleep disturbances (46.7%), changes in sex life (43.9) and hot flashes (42.9%). The majority of women would have found it helpful to have more information regarding the impact of this surgery on their sex life (59.2%), the availability of sex counseling (57.1%) and the risk of coronary heart disease (57.1%). This study illustrates that while health care providers are discussing selected side effects of PBSO, women undergoing this surgery have other concerns that should be addressed. This information provides insights into the informational needs of BRCA carriers considering PBSO.

Adjuvant endocrine therapy (ET) reduces the odds of distant recurrence and mortality by nearly one-half in women with hormone receptor (HR) positive early stage breast cancer. While the risk of recurrence is lower for HR positive than negative patients during the first 5-7 years, HR positive patients suffer ongoing recurrences between 0.5 and 2% year over subsequent years. Extended adjuvant ET further reduces recurrence during this late phase of follow-up. ET is associated with post-menopausal side effects (hot flashes, sexual dysfunction, mood changes, and weight gain), and occasional major toxicities (thrombosis and endometrial cancer with tamoxifen; bone mineral loss and possibly heart disease with AIs) persist throughout therapy. Accurate and reliable estimates of the risk of recurrence after five years of ET for women with prior HR positive breast cancer would permit appropriate extended ET decisions. The risk of long-term relapse is related to lymph node status and size of tumor, but these are relatively crude. Several groups have investigated whether multi-parameter tumor biomarker tests might identify those patients whose risk of recurrence is so low that extended ET is not justified. These assays include IHC4, the 21-gene "OncotypeDX", the 12-gene "Endopredict," the PAM50, and the 2-gene "Breast Cancer Index (BCI)" assays. The clinical validity of all these tests for this use context have been established, with at least one paper for each that shows a statistically significant difference in risk of distant recurrence during the 5-10 years after the initial five years of adjuvant endocrine therapy. However, the stakes are high, and although each of these represents a "prospective retrospective" study, they require further validation in subsequent datasets before they should be considered to have "clinical utility" and are used to withhold potentially life-saving treatment. Perhaps more importantly, the clinical breast cancer community, and especially the patient, need to determine how low the risk of late recurrence needs to be to forego the toxicities and side effects of extended adjuvant ET.

The release of the Women's Health Initiative (WHI) study in 2002 was a shock to the medical community. Hormone therapy (HT) had generally been considered to be highly beneficial for postmenopausal women since it was the gold standard for relief of menopausal symptoms (hot flashes, night sweats, vaginal atrophy) and it was thought to protect women from osteoporosis, heart disease, and cognitive decline and to generally improve quality of life. However, WHI showed a statistically significant increase in a number of disease states, including breast cancer, cardiovascular disease, and stroke. One problem with the WHI study was that the average age of women in the study was 63, which is considerably older than the age at which most women enter menopause (about 51). The timing hypothesis attempts to rationalize the effect of age on response to HT and risk of various diseases. The data suggests that younger women (50-60) may be protected from heart disease with only a slight increase in breast cancer risk. In contrast, older women (>65) are more susceptible to breast cancer and heart disease and should avoid HT. This Perspective on Statistical Trends evaluates the current data on HT and risk for chronic diseases as a function of age.
