Twenty-four women with large, myomatous uteri, measuring between 218.7 and 2,920 cm3 were treated with gestrinone, a tri-enic steroid with antiestrogen and antiprogesterone properties. In order to saturate the receptors of the large myomata, the doses used to treat these women were twice the recommended dosage of 2.5 mg, 3 times weekly, used to treat smaller tumors. The treatment lasted 6 months to 1 year. In all cases there was a reduction in uterine volume. In the 24 patients, the mean uterine volume of 724.9 cm3 on admission decreased to 450.73 cm3 at 6 months. For 14 patients treated for a full year, the mean uterine volume of 689.73 cm3 decreased to 329.22 cm3. Menstruation was suppressed in all patients by the end of the 2nd month of treatment. Episodic bleeding occurred in 6 patients but in only 1 did this last longer than 1 week. Other symptoms such as pelvic discomfort and dysuria disappeared or were significantly alleviated by the 2nd month of treatment. Side effects included seborrhea, acne, nervousness, myalgia and arthraglia, hoarseness and mild hirsutism but all these symptoms were promptly reversed following discontinuation. The mean increase in weight was 3.4 kg in 6 months. No menopausal symptoms such as hot flushes and depression developed during this trial. Six patients complained of excessive sweating. Blood glucose creatinine, blood urea nitrogen, alkaline phosphatase, pyruvic and glutamic transaminases remained within the normal range.

For the evaluation of climacteric symptoms, Kupperman and his collaborators worked out guidelines as long ago as 1953. As time passed, however, their validity was increasingly called into question. In the nineteen-seventies, on the basis of large epidemiological studies, the conclusion was drawn that merely the symptoms hot flushes and vaginal atrophy were specific to the menopause, while other, largely psychological, complaints represented a "domino effect", so to speak. In contrast to this, the scale (Menopause Rating Scale [MRS]) presented here also permits the identification of emotional complaints. In addition, urinary tract problems, joint and muscle pain, and sexual disorders are also rated. For each of the ten symptom groups, a graphical rating scale ranging from 0.0 (no symptoms) to 1.0 (severe symptoms) is available that permits a synoptic individual complaints profile of the patient to be established.

A pilot study of Formestane or 4-Hydroxyandrostenedione (Lentaron), a new endocrine agent, was conducted on 18 postmenopausal patients with locally advanced and metastatic breast cancer. 16 patients were evaluable for response and objective responses were seen in 4 patients (25%). Stabilisation of disease was seen in 5 patients (32%). Out of 17 patients evaluable for toxicity, 3 (18%) reported adverse effects including hot flushes, lethargy and myalgia. Adverse effects were mild, transient and no patient required discontinuation of drug. Our study confirms that Formestane is a well tolerated endocrine agent with low toxicity and reasonable efficacy in postmenopausal patients with locally advanced and metastatic breast cancer.

Letrozole (Femara), a nonsteroidal, third-generation aromatase inhibitor administered orally once daily, has shown efficacy in the treatment of postmenopausal women with early-stage or advanced, hormone-sensitive breast cancer. In early-stage disease, extending adjuvant endocrine therapy with letrozole (beyond the standard 5-year period of tamoxifen) improved disease-free survival; compared with placebo there was a 43% relative reduction in disease recurrences or new contralateral breast tumours at a median follow-up of 2.4 years. The results of 4 months' neoadjuvant treatment with letrozole or tamoxifen in postmenopausal women with untreated primary disease favour letrozole. In advanced breast cancer, letrozole was superior to tamoxifen as first-line treatment; time to disease progression was significantly longer (9.4 vs 6.0 months, p < 0.0001) and objective response rate was significantly greater with letrozole, but median overall survival was similar between groups. For second-line therapy of advanced breast cancer that had progressed on antiestrogen therapy, letrozole showed efficacy equivalent to that of anastrozole and similar to or better than that of megestrol acetate. Letrozole is generally well tolerated and has a similar tolerability profile to tamoxifen; the most common treatment-related adverse events were hot flushes, nausea and hair thinning. In patients with tumours that had progressed on antiestrogen therapy, letrozole was tolerated as least as well as, or better than, anastrozole or megestrol acetate. In the trial of extended adjuvant therapy, adverse events reported more frequently with letrozole than placebo were hot flushes, arthralgia, myalgia and arthritis. The long-term effects of letrozole on bone mineral density or lipid profile have not been determined and these parameters may require monitoring. In several pharmacoeconomic modelling studies from various public healthcare system perspectives, letrozole was considered a cost effective choice for first-line (vs tamoxifen) or second-line (vs megestrol acetate) treatment for advanced breast cancer in postmenopausal women. In conclusion, letrozole 2.5 mg/day is effective in the treatment of postmenopausal women with early-stage or advanced breast cancer. The efficacy, cost effectiveness and favourable tolerability profile of letrozole are reflected in current treatment guidelines recommending the drug as first-line therapy for advanced breast cancer. Letrozole is superior to tamoxifen for first-line treatment and is at least as effective as standard second-line treatments in disease that has progressed on antiestrogen therapy. For early-stage disease, letrozole is superior to tamoxifen in the neoadjuvant setting, and prolongs disease-free survival when administered after the standard 5-year period of adjuvant tamoxifen therapy.

The aromatase inhibitors deplete oestrogen by inhibiting aromatase, the enzyme that synthesises oestrogen from androgens. They are effective as therapies for breast cancer only in postmenopausal women whose tumours express oestrogen or progesterone receptors. As adjuvant therapy, tamoxifen and the aromatase inhibitors have similar efficacy in the first 5 years of treatment. Aromatase inhibitors can be used as an alternative to tamoxifen in women with symptomatic intolerance or a contraindication to tamoxifen. Early data suggest that switching to an aromatase inhibitor after 2-5 years of tamoxifen therapy is beneficial in women with high-risk disease. Aromatase inhibitors are associated with more hot flushes than placebo, but with fewer hot flushes, less endometrial toxicity and venous thromboembolism, and more arthralgia, myalgia and bone fracture than tamoxifen.

Adjuvant endocrine therapy plays an important role in the management of hormone-receptor-positive early breast cancer, and has increased life expectancy for millions of women. Many patients receive adjuvant treatment for at least 5 years following tumor resection, hence good long-term safety is important for endocrine agents to gain widespread acceptance. Tamoxifen has been used as adjuvant therapy for early breast cancer for many years, and safety data have been well documented, but a poor risk:benefit profile limits treatment duration to 5 years. Increased efficacy over tamoxifen and good tolerability have recently made the third-generation aromatase inhibitors (AIs) the first-choice agents for adjuvant endocrine therapy; however, it is currently not known whether AI therapy, like tamoxifen, will be limited to 5 years. Many side effects of endocrine therapy, such as hot flushes and mood disturbances, are related to estrogen deprivation and are common to tamoxifen and AIs, reflecting the mechanism of action of these drugs. In addition, tamoxifen has estrogenic effects that are beneficial in some tissues: tamoxifen lowers serum cholesterol levels and protects against bone loss and cardiovascular disease, but is also associated with potentially life-threatening side effects, such as endometrial cancer and thromboembolic disease. As AIs lack estrogenic activity, they are not associated with these serious adverse events. Clinical trials comparing AIs with tamoxifen in the adjuvant setting have shown that AIs are well tolerated and are associated with a lower incidence of gynecological symptoms and hot flushes than tamoxifen. However, AIs are associated with musculoskeletal side effects, such as arthralgia, myalgia and bone loss, but these events are preventable or manageable. The effects of AIs on lipid metabolism and the cardiovascular system are still debatable, but placebo-controlled trials provide no evidence to suggest that AIs adversely affect these systems. Furthermore, the AIs allow women to maintain a good quality of life, comparable with women receiving tamoxifen or placebo, and are a cost-effective therapeutic option. Ongoing trials will provide more information regarding the long-term effects of AI therapy and will provide comparative data on the efficacy and safety of the different AIs, thereby helping to determine the optimal treatment strategy for these highly effective and well-tolerated drugs.

This study investigated the effects of aromatherapy massage on menopausal symptoms in Korean climacteric women. Kupperman's menopausal index was used to compare an experimental group of 25 climacteric women with a wait-listed control group of 27 climacteric women. Aromatherapy was applied topically to subjects in the experimental group in the form of massage on the abdomen, back and arms using lavender, rose geranium, rose and jasmine in almond and primrose oils once a week for 8 weeks (eight times in total). The experimental group reported a significantly lower total menopausal index than wait-listed controls (P < 0.05). There were also significant intergroup differences in subcategories such as vasomotor, melancholia, arthralgia and myalgia (all P < 0.05). These findings suggest that aromatherapy massage may be an effective treatment of menopausal symptoms such as hot flushes, depression and pain in climacteric women. However, it could not be verified whether the positive effects were from the aromatherapy, the massage or both. Further rigorous studies should be done with more objective measures.

For the medical treatment of early breast cancer, aromatase inhibitors (AIs) such as anastrozole, letrozole, and exemestane are more effective than selective estrogen-receptor modulators (SERMs) such as tamoxifen (TAM). However, the adverse events associated with AIs are different from those associated with SERMs. Hot flushes, gynecological disorders, and thrombosis are more frequent in patients treated with TAM than in those treated with AIs. Conversely, osteoporosis, fractures, joint symptoms, and myalgia are more common in patients receiving AIs. Osteoporosis and bone fractures resulting from osteoporosis are important issues for patients treated with AIs. The precise management of bone health, in strict accordance with clinical guidelines, is vital in patients receiving AIs. AI-related joint symptoms are also one of the most important considerations for patients taking AIs. AI-related joint symptoms are the most common reason for the discontinuation of AIs. Confirmed management strategies for AI-related joint symptoms are unavailable at present. In patients receiving AIs, long-term adverse events (for example, those occurring as a result of changing lipid metabolism) remain unclear. There is a clear need to elucidate AI-related adverse events over the long term and to establish management strategies for AI-related adverse events, such that AIs can be used safely in patients with breast cancer over long periods of time.

The current adjuvant therapy for breast cancer is in a continous progress; standard therapeutic strategies include the use of chemotherapy, molecular targeted drugs and hormonal agents, according to well-established prognostic and predictive factors. Among the hormonal drugs, for a long period tamoxifen has been the gold standard of adjuvant therapy in postmenopausal women with hormone receptor-positive (HR+) early breast cancer. In the last years an expanding use of aromatase inhibitors occurred in this subset of patients, because the third-generation class of these agents (anastrozole, letrozole and exemestane) showed to be more effective and safe than tamoxifen and are now recommended as the preferred hormonal approach to postmenopausal hormone-sensitive patients, according to national and international guidelines. Treatment choices with these agents include the use of an aromatase inhibitor as an upfront strategy for 5 years, as a sequential approach after 2-3 years of tamoxifen, or as an extended use after the classical 5 years of tamoxifen. The improved efficacy of aromatase inhibitors over tamoxifen has been largely demonstrated in terms of better disease-free survival, reductions in the occurrence of early distant metastasis as well as improvement of overall survival. Moreover, according to the optimal duration of therapy, presently it is not known whether aromatase inhibitor therapy, as tamoxifen, should be limited to 5 years. In terms of safety profile, the side effects of aromatase inhibitors, as compared with selective estrogen receptor modulators, are different, reflecting the specific mechanism of action of these drugs. There is strong evidence that aromatase inhibitors are well tolerated, with a lower incidence of gynecological symptoms (vaginal bleeding, discharge and endometrial neoplasia), venous thromboembolic events and hot flushes than tamoxifen. On the other hand, the use of aromatase inhibitors has been associated with loss of bone density, arthralgia, myalgia, and a negative effect on lipid metabolism and cardiovascular risk. More extensive and mature studies are necessary to well establish the safety of aromatase inhibitors when given to patients with breast cancer for a long time.

Letrozole is a type 2 aromatase inhibitor, which reduces availability of estrogen in postmenopausal women, thereby decreasing its ability to stimulate breast cancer cells. Phase III trials in both the advanced and early breast cancer setting have shown an improvement in disease-free survival compared with other compounds, including tamoxifen. Letrozole is well-tolerated, with the main adverse effects reported as hot flushes, arthritis, arthralgia and myalgia, and a trend towards increased risk of fracture.
