Uterine fibroids are common benign neoplasms, with a higher prevalence in older women and in those of African descent. Many are discovered incidentally on clinical examination or imaging in asymptomatic women. Fibroids can cause abnormal uterine bleeding, pelvic pressure, bowel dysfunction, urinary frequency and urgency, urinary retention, low back pain, constipation, and dyspareunia. Ultrasonography is the preferred initial imaging modality. Expectant management is recommended for asymptomatic patients because most fibroids decrease in size during menopause. Management should be tailored to the size and location of fibroids; the patient's age, symptoms, desire to maintain fertility, and access to treatment; and the experience of the physician. Medical therapy to reduce heavy menstrual bleeding includes hormonal contraceptives, tranexamic acid, and nonsteroidal anti-inflammatory drugs. Gonadotropin-releasing hormone agonists or selective progesterone receptor modulators are an option for patients who need symptom relief preoperatively or who are approaching menopause. Surgical treatment includes hysterectomy, myomectomy, uterine artery embolization, and magnetic resonance–guided focused ultrasound surgery.
A multi-center, single-arm, open-label study was conducted in 28 girls with McCune-Albright Syndrome and progressive precocious puberty aged 2 to < 10 years. All patients received a 1 mg daily dose of ARIMIDEX. The trial duration was 12 months. Patients were enrolled on the basis of a diagnosis of typical (27/28) or atypical (1/27) McCune-Albright Syndrome, precocious puberty, history of vaginal bleeding, and/or advanced bone age. Patients' baseline characteristics included the following: a mean chronological age of ± years, a mean bone age of ± years, a mean growth rate of ± cm/year and a mean Tanner stage for breast of ± . Compared to pre-treatment data there were no on-treatment statistically significant reductions in the frequency of vaginal bleeding days, or in the rate of increase of bone age (defined as a ratio between the change in bone age over the change of chronological age). There were no clinically significant changes in Tanner staging , mean ovarian volume, mean uterine volume and mean predicted adult height. A small but statistically significant reduction of growth rate from ± cm/year to ± cm/year was observed but the absence of a control group precludes attribution of this effect to treatment or to other confounding factors such as variations in endogenous estrogen levels commonly seen in McCune-Albright Syndrome patients.
Gynecomastia is a common adverse effect of bicalutamide (Casodex) therapy that may prompt some men to discontinue prostate cancer treatment. Tamoxifen has been recommended as a preventive agent for gynecomastia in these patients. A double-blind study of 282 men randomized to receive 20 mg of tamoxifen once per day with bicalutamide or bicalutamide alone found that after six months, gynecomastia and breast pain were significantly reduced in men who received tamoxifen ( versus percent in the control group). 41 An Italian randomized controlled trial of 80 participants also found that 20 mg of tamoxifen once per week is as effective as 20 mg once per day. 42
