RU-486 or mifepristone is best known as an antiprogestin and an abortifacient, but it has broad medical applicability. The drug is also a potent blocker of corticosteroid receptors, and it has shown promise in the treatment of breast cancer, inoperable meningioma, and cushing's disease. Cushing's is a model for the symptomatology of aging which may involve enhanced response to corticosteroid. RU-486 has reversed the osteoporosis, thinning of skin, muscle atrophy, obesity, adult onset diabetes, depression, hypertension, and immunosuppression associated with this disease. RU-486 may be of value in aiding cervical dilation, lactation, and the treatment of endometriosis. In addition, breast, bowel, kidney tumors, hepatomas, endometrial cancer, and fibrosarcomas can show corticosteroid dependency, suggesting that RU-486 may have clinical value against inoperable tumors. In a preliminary 1987 phase I study, in estrogen-positive, chemotherapy-refractory breast cancer patients in Montpelier, France, Ru-486 produced objective tumor regression (6 of 22) that was prolonged (3 months) in 4 patients. Clinical relief of bone pain was observed in 7 of 23 patients with a decline in carcinoembryonic antigen (CEA) tumor makers in 8 patients. Growing in vitro data also show that RU-486 can directly inhibit breast cancer cell proliferation. RU-486 has application for HIV infection, based on data that there is a serum factor in AIDS patients that enhances corticosteroid lympholysis. IN addition, the immune restorative action of RU-486 suggests that it could counteract the immunosuppression seen in aging, in cancer, or in viral or stress-related disease, which has recently focused clinical attention on its potential in the treatment of senile dementia and depression. Scientific conferences and workshops are needed to alert scientists, physicians, and the public to the potential medical benefits of this drug.

Tamoxifen, once the gold standard adjuvant endocrine therapy for early breast cancer, is being challenged by third-generation aromatase inhibitors (AIs) that have demonstrated improved disease-free survival in a variety of adjuvant settings for early breast cancer. Tamoxifen and AIs have different safety profiles, which should allow physicians to begin to individualize treatment based on a patient's comorbidities and risk factors. Because of its properties as a partial estrogen agonist, tamoxifen has a positive effect on serum lipids and may confer a cardioprotective benefit, as well as a beneficial effect on bone health. However, tamoxifen increases the risk for endometrial cancer and cerebrovascular/thromboembolic events. In comparison, the major side effect of AIs is increased bone loss, which may heighten the risk for osteoporotic fractures and bone pain. Because of their superior efficacy and manageable side effects, AIs are a cost-effective alternative to tamoxifen, and clinical guidelines now embrace AIs as appropriate adjuvant therapy for hormone-sensitive early breast cancer. The anticipated results of ongoing trials will provide further insights into the long-term safety and application of AI therapy in the adjuvant setting.

Although metastasis to the bone is common in solid tumors, it seldom occurs in endometrial cancer. A rare case of endometrial carcinoma that presented wth symptoms of bone metastasis in the right ischium and treated successfully by zoledronic acid is described. A 57-year-old woman presented with pain of the right ischium. Computed tomography and magnetic resonance imaging revealed bone metastasis and enlargement of the uterus. Endometrial biopsy confirmed endometrial adenocarcinoma. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy and biopsy of the ischium. Postoperatively, the patient received six courses of chemotherapy using paclitaxel and carboplatin. However, pain of the right-ischium reappeared 9 months after surgery. The patient was treated with 4 mg of zoledronic acid every 4 weeks. After 4 cycles of treatment, the visual analogue scale regressed from 70 to 10. Zoledronic acid can palliate bone pain caused by a variety of endometrial cancers.
