As survival from breast cancer increases, there is a corresponding rise in the number of women living with the long-term consequences of its treatment. Distressing menopausal hot flushes occur in many of these women. This article reports on interviews conducted with 8 women, exploring the experience of hot flushes after breast cancer. Women's accounts of hot flushes varied from being a mild sensation to an intensely unpleasant sensation affecting the whole body and accompanied by drenching perspiration. Flushes affected all aspects of the women's lives, including sleeping, clothing, social situations, intimate relationships, and ability to work. Emotionally, women talked about being out of control. Having cancer and menopause simultaneously made it more difficult for the women to cope, and cancer treatment could cause flushing. The women used many strategies to help relieve their difficulties. Some resorted to hormone replacement therapy, whereas others turned to herbal medications and other alternative interventions such as acupuncture. Most women adopted behavioral strategies to try to regain control. Ultimately, they found that control was gained by attitude of mind. Cognitive behavioral techniques may enhance the sense of control and contribute to coping during hot flushes.

Tamoxifen has been found to be safe and effective in gynecological cancer patients with normal renal function. However, to our knowledge, no data exist regarding its effectiveness and toxicity in gynecological cancer patients with chronic kidney disease (CKD). Therefore, we retrospectively evaluated the effects of tamoxifen in patients with recurrent gynecological cancer and CKD. We collected clinical and demographic data for all patients. CKD was defined as a creatinine clearance (CrCl) level of less than 90 mL/min/1.73 m(2), in accordance with the National Kidney Foundation Kidney and Dialysis Outcomes Quality Initiative, and further categorized as mild, moderate, or severe (CrCl levels of 60-89, 30-59, and <30 mL/min/1.73 m(2), respectively). Twenty-nine patients were included in the study--22 with epithelial ovarian cancer, 4 with peritoneal cancer, and 3 with fallopian tube cancer. Thirteen patients had mild CKD, 13 had moderate, and 3 had severe. Most patients had been treated with 20 mg/day of tamoxifen every 4 weeks. The median duration of treatment was 5 months (range, 1-52 months). The overall complete response, partial response, stable disease, and disease progression rates were 0%, 10%, 41%, and 48%, respectively. Twenty-one percent of patients experienced hot flashes, and 7% experienced nausea. No major adverse reactions occurred. These findings were similar to those for gynecological cancer patients with normal renal function. In conclusion, 20 mg/day of tamoxifen is safe and effective in gynecological cancer patients with CKD.

Night sweats has been defined as drenching sweats that require the patient to change bed clothes. In current studies night sweats appear in 30% of non-obstetric patients and affects approximately 60% of pregnant women. Differential diagnoses include infections, malignancy, medications, hot flashes and panic attacks, making of each patient a challenge. We present two patients with night sweating. After excluding systemic diseases the diagnosis of gastroesophageal reflux was made, with excellent response to anti-reflux treatment. The presentation of our two patients coupled with a deep literature review, underscores the importance of gastroesophageal reflux as a cause of night sweating.

The third-generation aromatase inhibitors (AIs) letrozole, anastrozole, and exemestane are replacing tamoxifen as adjuvant therapy in most postmenopausal women with early breast cancer. Although AIs have demonstrated superior efficacy and better overall safety compared with tamoxifen in randomized controlled trials, they may not provide the cardioprotective effects of tamoxifen, and bone loss may be a concern with their long-term adjuvant use. Patients require regular bone mineral density monitoring, and prophylactic bisphosphonates are being evaluated to determine whether they may protect long-term bone health. AIs decrease the risks of thromboembolic and cerebrovascular events compared with tamoxifen, and the overall rate of cardiovascular events in patients treated with AIs is within the range seen in age-matched, non-breast-cancer populations. AIs are also associated with a lower incidence of endometrial cancer and fewer vaginal bleeding/discharge events than tamoxifen. Compared with tamoxifen, the incidence of hot flashes is lower with anastrozole and letrozole but may be higher with exemestane. Generally, adverse events with AIs are predictable and manageable, whereas tamoxifen may be associated with life-threatening events in a minority of patients. Overall, the benefits of AIs over tamoxifen are achieved without compromising overall quality of life.

Five years of adjuvant therapy with tamoxifen was considered the gold-standard treatment for postmenopausal women with estrogen receptor-positive breast cancer for many years. Data from a core group of clinical trials investigating the safety and efficacy of aromatase inhibitors (AIs) have challenged this perception. These studies were designed to evaluate the safety and efficacy of AIs in the following clinical settings: 1) as initial adjuvant therapy (the Arimidex, Tamoxifen, Alone or in Combination trial, Breast International Group Trial 1-98), 2) in a "switched setting" after 2 to 3 years of treatment with tamoxifen (Arimidex-Nolvadex 95, the Austrian Breast and Colorectal Cancer Study Group 8 [ABCSG 8] trial, the Italian Tamoxifen Anastrozole study, the Intergroup Exemestane Study), and 3) in extended settings (National Cancer Institute of Canada Trial MA.17, ABCSG 6a, National Surgical Adjuvant Breast and Bowel Project 33). The efficacy data from these studies suggested that AIs have added substantial benefit in terms of disease outcome. AIs were tolerated well, and patients who received them experienced fewer thrombolic events and less endometrial cancer, hot flashes, night sweats, and vaginal bleeding compared with patients who receive tamoxifen. However, patients who received tamoxifen had less skeletal events and accelerated bone resorption compared with women who received AIs. AIs should be considered when planning a patient's endocrine therapy, taking into account the differences in tolerability and end-organ effects of the classes of endocrine therapy. Outstanding issues to optimize AI therapy include identifying the optimal duration, agent, and patients for these therapies.

The occurrence of vasomotor symptoms in women is directly related to deficiency of estrogen, which occurs as a result of natural or surgical menopause. Hot flushes may also be a major problem for patients with a history of breast cancer, as they may result directly from cancer treatment (oophorectomy, chemotherapy-induced ovarian failure or adjuvant tamoxifen citrate therapy). Despite the lack of reliable data regarding their efficacy and safety, in recent years the usage of herbs among menopausal women has increased dynamically all over the world. The following paper reviews professional literature about Black Cohosh (Actaea/Cimicifuga racemosa), either used alone or in combination with other medicinal herbs administered in management of vasomotor symptoms. Extracts of the rootstock of Black cohosh contain such potentially biologically active constituents as triterpene glycosides (actein, cimicifugoside, deoxyacetein), isoferulic acid and alkaloids (n-methylcytisine). The mechanism of its action remains unclear. Some authors suggest that Black Cohosh contains substances with selective estrogen receptor modulator (SERM) activity. Recent data has demonstrated that Black Cohosh may have an effect on dopaminergic and serotoninergic systems. Thirty-two papers formed the basis for this review. Open-label, noncomparative studies, as well as treatment-controlled, randomized, open trials, have proven that Black Cohosh significantly reduced frequency or severity of hot flashes. The results of randomized, placebo-controlled, double-blind clinical trials were contradictory. Adverse symptoms have been rare (5,4%), mild and reversible. Most of them included gastrointestinal upsets, rashes, headaches, dizziness and mastalgia. Nevertheless, single cases of serious adverse events, including acute hepatocellular damage, have been reported, but without a clear causality relationship.

The use of androgen deprivation therapy (ADT) to treat prostate cancer has favorably impacted outcomes for men with prostate cancer. Androgen deprivation therapy is effective in reducing painful bony metastases and soft tissue visceral disease in advanced-stage prostate cancer. The use of ADT has expanded beyond the metastatic setting and can also be used as adjuvant therapy for patients with locally advanced prostate cancer who received surgery or localized radiation therapy. Luteinizing hormone-releasing hormone agonists are the most common medical therapy used to deprive men of androgen production. Despite the beneficial effects that ADT has on prostate cancer, ADT causes side effects that can impair quality of life. This article will review the impact and treatment of hot flashes in men treated for prostate cancer.

More than 86% of those diagnosed with invasive breast cancer are expected to survive for >/= 5 years after their diagnosis. Approximately 75% of postmenopausal women who had breast cancer report experiencing hot flashes. More than 90% of young survivors also experience hot flashes, which can be more severe and long lasting, with iatrogenic ovarian ablation or antiestrogen therapy. There are numerous options for the treatment of hot flashes. Not one treatment fits all. Some treatments are generally more effective than others, and each has different side effects. This review is meant to provide the basic information needed to make a decision about the best treatment for a breast survivor experiencing hot flashes.

During the past decade, the critical role of sleep in health and disease has been underscored by research that further defines the relationship between sleep and myriad physiologic and psychological functions as well as quality of life. For many years, there was little exploration of the significance of sleep and sleep disorders in cancer patients; however, the past decade has seen a steady growth of inquiry in this area. These investigations have demonstrated the high frequency and significance of sleep disturbance as a symptom in cancer patients. They have also explored the complex interaction between sleep and other common cancer symptoms, most notably fatigue, depression, and pain, and have identified risk factors associated with the development of sleep problems in this population. Although treatment studies lag behind, reports of effective psychological and behavioral interventions for insomnia in cancer patients are increasing. Several studies are addressing pharmacotherapeutic intervention for hot flashes as a potential source of sleep disturbance. Other sleep disorders, most notably obstructive sleep apnea, also occur with some regularity in cancer patients.
