Because side-effects of chemotherapy may be more diverse and patients' reactions more individualistic than tends to be acknowledged by clinicians, a survey was carried out among 50 breast cancer outpatients to document self-reported physical symptoms experienced during NCF (mitoxantrone + cyclophosphamide + 5-fluorouracil) adjuvant chemotherapy and to compare them with the clinicians' estimation in medical records. The questionnaire evaluated the prevalence, duration/severity and distress level of 17 symptoms. Symptom prevalence, assessed in 231 cycles, was high even for symptoms that do not usually focus clinicians' attention. Of these, hot flushes, stomach pain and muscular and articular pains lasted 1 week or more for nearly half of the cycles. Hot flushes, vomiting and stomach pain were the most distressing symptoms. The mean number of symptoms per cycle is significantly correlated with the global quality-of-life score. Concordance between patients' self-assessment and clinical reports, measured in 180 cycles, is moderately correct for vomiting and sore mouth and inadequate for the remaining symptoms even for hair loss (notified in 27% of cycles by clinicians vs 80% by patients) and nausea (38% vs 73%). A better understanding by physicians of cancer patients' problems is necessary to improve quality of care.

There are limited data on the factors associated with menopausal hot flashes, a common and potentially morbid condition. The objective of this study was to identify predictors of menopausal hot flashes. To meet this objective, 233 naturally perimenopausal or post-menopausal women (ages 45-65) attending a large urban hospital center primary care clinic, mammography unit, or women's health practice were enrolled. The women responded to a self-administered questionnaire assessing selected demographic factors, reproductive history, and behavioral factors. Sixty-seven percent of respondents experienced hot flashes, with 63% reporting frequent hot flashes (at least one hot flash per day) and 60% with hot flashes describing the hot flashes as severe. Women with hot flashes were significantly more likely to have mothers who experienced hot flashes (OR = 4.4, CI = 2.0-10.0) or to be smokers (OR = 2.0, CI = 1.2-3.5). There were no statistically significant associations between hot flashes and other selected demographic, reproductive, or behavior characteristics. These results reveal that menopausal hot flashes are associated with a maternal history of hot flashes as well as with cigarette smoking. These results may help physicians to counsel their patients about smoking cessation.

Little is known about the long-term effects of adjuvant therapy on quality of life, sexual functioning and symptoms in breast cancer survivors. Between January 1996 and June 1997, we surveyed 1098 women who had been diagnosed with early stage breast cancer between 1 and 5 years earlier. The breast cancer survivors were recruited in two large metropolitan centers in the USA. They completed a survey battery that contained standardized measures of health-related quality of life (HRQL), depression, body image, sexual functioning, and symptoms. A total of 1096 had usable responses for these analyses. In this sample, n = 356 had received tamoxifen (TAM) alone, n = 180 received chemotherapy (CHEM) alone, n = 395 received CHEM + TAM, and n = 265 received no adjuvant therapy (NO RX). There were significant differences in the mean age of each group, with the TAM group being the oldest (mean 62.6 years) and the CHEM group being the youngest (mean 46.8 years). Both age and time since diagnosis were controlled for in all statistical analyses. We found no significant differences in global quality of life among the four treatment groups. For the MOS-SF-36, there were no significant differences on the subscale scores except for the physical functioning subscale (p = 0.0002); the NO RX group had the highest functioning. There were no significant differences in depression scores among the four treatment groups. The MOS-SF-36 physical functioning composite score differed by treatment group (p = 0.012); the NO RX group had a physical functioning composite score that was at the mean for a normal healthy population of women, while those in the adjuvant treatment groups scored slightly lower. The mental health composite score was not significantly different among the four treatment groups and approximated scores from the normal population of healthy women. There were no differences in body image scores among the four treatment groups; however, sexual functioning scores did differ (p = 0.0078) with patients receiving chemotherapy (either alone or with tamoxifen) experiencing more problems. Hot flashes, night sweats, and vaginal discharge differed by treatment (p = 0.0001); all symptoms were reported more often in breast cancer survivors on tamoxifen. Vaginal dryness and pain with intercourse also differed significantly by adjuvant treatment, occurring more often in survivors treated with chemotherapy. Overall, breast cancer survivors function at a high level, similar to healthy women without cancer. However, compared to survivors with no adjuvant therapy, those who received chemotherapy have significantly more sexual problems, and those treated with tamoxifen experience more vasomotor symptoms.

Estrogens are known as potent mammary mitogen substances and are the major stimulus for the growth of hormone-dependent tumors and clearly implicated in the pathogenesis of breast cancer. Therefore it is a general belief that hormone replacement therapy (HRT) after breast cancer will increase the risk of developing recurrences, though there are no clear data available to support this suggestion. No prospective study with a large number of patients and a long treatment period was performed concerning this issue. On the other hand it may not be justifiable to withhold hormone replacement therapy from low-risk patients after menopause, knowing the benefits of this therapy concerning osteoporosis and cardiovascular advantages. Nevertheless, until appropriate clinical trials help to resolve this problem, non hormonal alternatives constitute the standard of care. One possible approach is to treat menopausal women who have had breast cancer symptomatically and avoid ERT unless absolutely necessary. The risk of cardiovascular diseases can be reduced with lifestyle. Tamoxifen has a beneficial effect on serum lipids and the intake for 5 years leads to a 50% reduction in the incidence of fatal myocardial infarction and a decrease in morbidity associated with ischaemic heart disease. Low doses of progestogen is effective for menopausal hot flushes. Tibolone reduces vasomotoric symptoms such as hot flushes and offers benefit on osteoporosis and has shown a significant reduction in high-density lipoprotein cholesterol. Whether replacing of estrogens is safe for patients after breast cancer remains uncertain. There is a need for a large controlled clinical trial to evaluate the safety and advantages of long time estrogen replacement in women treated for breast cancer.

A new drug class called Selective Estrogen Receptor Modulators (SERM) could combine ideal properties for a product designed for menopausal women. The most widely studied member of this class is raloxifene which is currently marketed in several countries for the prevention of osteoporosis in menopaused women. This product is a nonsteroidal derivative of benzothiophene which, like estrogens, has a preventive effect against bone loss involving the spine and peripheral skeleton and a cholesterol lowering effect, both in the ovariectomized rat and in menopausal women. Unlike estrogens, raloxifene does not stimulate breast or uterine tissue. These interesting properties make raloxifene a possible preventive treatment for osteoporosis and other menopause-related risks for menopausal women of all ages. Multicenter studies have been conducted in recently menopausal women who received either raloxifene at the doses of 30, 60, or 150 mg/day or a placebo in a randomized protocol. All subjects were also given calcium supplementation. Bone density was measured twice a year for 36 months by dual X-rays absorptiometry and showed a significant decrease at all sites in the placebo group while there was a significant increase in the spine, the hip and the overall skeleton for all three raloxifen groups. After 24 months of treatment, mean increase over placebo was 2.4% for 60 mg raloxifene measured on the spine and total hip and 2% for the overall skeleton. Markers of bone formation (serum osteocalcin and bone alkaline phasphatase) and resorption (urinary CrossLaps) decreased significantly reaching, after 3 to 6 months of treatment, the levels observed in non menopausal women. In addition, total serum cholesterol as well as LDL-cholesterol decreased significantly in a dose-dependent fashion in all groups treated with raloxifene. Serum HDL-cholesterol and triglycerides did not very significantly during treatment. Hot flashes were the most frequently observed undesirable effect, at a frequency slightly higher in the raloxifene group (25%) than in the placebo group (18%). This undesirable effect was of low intensity and generally occurred during the first months of treatment. It did not cause a higher drop out rate (raloxifen 1.5%; placebo 2.1%). The preliminary data at two years follow-up suggest that raloxifene is not associated with an increased risk of breast cancer. In conclusion, raloxifene is a particularly interesting drug for menopausal women showing very promising efficacy and clinical tolerance.

There are very few data about the efficacy and toxicity of adjuvant systemic therapies for breast cancer in non-western populations. In 1993 in Vietnam we began a randomized controlled clinical trial on premenopausal women with operable breast cancer comparing adjuvant surgical oophorectomy plus tamoxifen with observation and this same combined hormonal treatment on recurrence. We evaluated the symptoms reported at regular follow-up visits by the first 482 premenopausal women entered in this clinical trial and treated with surgical oophorectomy plus tamoxifen or observation. Hot flash frequency and intensity, vaginal discharge, and genital pruritus were the only symptoms to occur more frequently in oophorectomy and tamoxifen-treated subjects. Seventy-seven percent of oophorectomy/tamoxifen subjects reported grade 1 or more and 44% grade 2 or more hot flash frequency symptoms in the first 12 months, versus 9% and 1% of observation subjects, respectively. Twenty percent of oophorectomy/tamoxifen subjects had grade 2 or greater intensity of hot flashes some time in the first 12 months versus 0% in observation subjects. Through three years, vasomotor symptoms were reported more frequently in oophorectomy/tamoxifen-treated women (in 23% vs. 3% at three years, mostly grade 1 toxicities). While noted and persistent vasomotor symptoms were found with oophorectomy plus tamoxifen in this population of Vietnamese women, these were of lower grades and tolerable. This adjuvant treatment may be widely accepted if it is demonstrated to be effective in this population.

The use of hormone replacement therapy after breast cancer is controversial. The published epidemiological studies shown no association between HRT and recurrence of breast cancer. However, the interpretation of these results is very difficult because of numerous biases in this context of observational studies. Prospective randomised trials that examine the effects of HRT in women with a history of breast cancer are currently underway in United States and in Scandinavia. The markov approach is interesting for determining the global risk-benefit balance of HRT and for visualising the effects of different risk levels on breast cancer and to compare different therapeutic strategies. Hot flushes and functional symptoms represent the essential unresolved problem of these women. The results of all these will provide valuable data to define efficient and non-deleterious approaches to improve the well being of the women after breast cancer.

Hot flashes are among the most commonly reported symptoms among women who have completed treatment for breast cancer. Relatively little is known, however, about hot flashes among women while they are undergoing breast cancer treatment. The present study investigated the prevalence and severity of hot flashes of women during chemotherapy and radiotherapy for breast cancer. We also sought to identify the medical, demographic, and treatment correlates of hot flashes during treatment and to document the impact of hot flashes on quality of life. Seventy postmenopausal women with breast cancer completed a self-report questionnaire packet during chemotherapy and radiotherapy. Forty percent (n = 28) reported hot flashes during the week prior to assessment. Of the 28 women endorsing hot flashes, 25% (n = 7) rated them as severe, 39% (n = 11) rated them as moderate, and 36% (n = 10) rated them as mild. Women with hot flashes were significantly (p < 0.05) younger and reported significantly (p < 0.001) more fatigue, poorer sleep quality, and poorer physical health compared to women without hot flashes. Multivariate analyses revealed that, even after controlling for relevant medical, demographic, and treatment variables, the prevalence of hot flashes significantly (p < 0.05) predicted poorer sleep quality, more fatigue, and worse physical health. The results indicate that hot flashes are experienced by a sizable percentage of postmenopausal breast cancer patients as they undergo treatment. Hot flashes during cancer treatment appear to have a negative impact upon patient quality of life that may be due, in part, to fatigue and interference with sleep. Future research should seek to evaluate interventions to relieve hot flashes during breast cancer treatment as a means of improving patient quality of life.

A community-based survey was conducted during 1995-1997 of factors related to menopausal and other symptoms in a multi-racial/ethnic sample of 16,065 women aged 40-55 years. Each of seven sites comprising the Study of Women's Health across the Nation (SWAN) surveyed one of four minority populations and a Caucasian population. The largest adjusted prevalence odds ratios for all symptoms, particularly hot flashes or night sweats (odds ratios = 2.06-4.32), were for women who were peri- or postmenopausal. Most symptoms were reported least frequently by Japanese and Chinese (odds ratios = 0.47-0.67 compared with Caucasian) women. African-American women reported vasomotor symptoms and vaginal dryness more (odds ratios = 1.17-1.63) but urine leakage and difficulty sleeping less (odds ratios = 0.64-0.72) than Caucasians. Hispanic women reported urine leakage, vaginal dryness, heart pounding, and forgetfulness more (odds ratios = 1.22-1.85). Hot flashes or night sweats, urine leakage, and stiffness or soreness were associated with a high body mass index (odds ratios = 1.15-2.18 for women with a body mass index > or =27 vs. 19-26.9 kg/m2). Most symptoms were reported most frequently among women who had difficulty paying for basics (odds ratios = 1.15-2.05), who smoked (odds ratios = 1.21-1.78), and who rated themselves less physically active than other women their age (odds ratios = 1.24-2.33). These results suggest that lifestyle, menstrual status, race/ethnicity, and socioeconomic status affect symptoms in this age group.

Hot flushes are experienced in those periods of the female life when estrogen levels are low. Hormone replacement therapy is thus the first choice for treatment of hot flushes. However this treatment is not always accepted or contraindicated for a variety of reasons. Estrogen (and progestogen) strongly interact with a number of neurotransmitters and this has led to a range of non-hormonal treatments including compounds that act via the noradrenergic or dopaminergic systems as well as herbal remedies. These treatments (which are shortly reviewed) are not always successful. Surprisingly, apart from treatment with some selective serotonin (5-HT) reuptake inhibitors (SSRI's), up till now, little attention is given to the strong interaction of estrogens with the serotonergic system. These interactions are shortly reviewed. Based on these interactions, a hypothesis on the genesis of hot flushes is postulated. Especially the 5-HT(2A) receptor subtype may play a key role in the occurrence of hot flushes. A number of arguments that support this hypothesis are discussed.
