In order to determine the usual dose in the first line therapy and a high dose in the second or third line therapy, a dose finding study of a novel antiestrogen NK 622 (toremifene citrate) was performed in patients (pts) with advanced or recurrent breast cancer. NK 622 was orally administered daily once for more than 8 weeks. In pts without previous drug therapy or in pts with cancer relapse after adjuvant therapy, the response rates [(CR + PR)/total] were 24.1% (7/29), 13.8% (4/29), 20.0% (1/5) and 40.0% (2/5) at doses of 40, 60, 120 and 240 mg/day, respectively. A 40 mg/day dose showed an objective response only in postmenopausal pts with estrogen receptor (ER) positive or unknown cancer. At a dose of 60 mg/day, some of the responding cases were premenopausal pts or pts with ER(-) cancer. In pts with cancer relapse during adjuvant therapy or in those with previous therapy and/or radiation, response rates were 25.0% (2/8), 0% (0/4), 13.5% (5/37) and 10.3% (4/39) at doses of 40, 60, 120 and 240 mg/day, respectively. Response was more frequent in pts with ER (+) cancer than with ER (-) cancer. The response rates in pts with previous therapy including tamoxifen (TAM) except medroxyprogesterone (MPA) were 14.3% (4/28) at a 120 mg/day dose and 6.1% (2/33) at a 240 mg/day dose. In pts with previous therapy including TAM, MPA and other antitumor agents, the rate was 18.2% (2/11) at a 120 mg/day dose. Side effects such as elevation of GOT, GPT and serum Ca level, decrease of hemoglobin, anorexia, nausea/vomiting, fatigue, dizziness and hot flush were observed. These side effects were moderate in grade and reversible. Dose dependency of side effects was not clearly observed in grade and incidence. From these results, NK 622 is expected to be a safe drug with efficacy in first line therapy at a dose of 40 mg/day and in second or third line therapy at a dose of 120 mg/day.

The most frequent symptom with leiomyoma is menometrorrhagia. However, it can be responsible of pelvic pain, dysmenorrhea or urinary and digestive compression when it is particularly voluminous. These recommandations were made in order to review medical management of fibroids. If no therapy is able to have them disappear, various drugs may reduce their related symptoms. Tranexamic acid, non-steroidal anti-inflammatory drugs and high dose of oestrogen may be useful in the management of acute hemorrhagic disorders. Progestin, such as lynestrenol induces small reduction in leiomyoma volume and moderate increase in hemoglobin level before surgery. Pregnane and nor-pregnane may improve menstrual bleeding in short or mild delays. The use of Gonadotropin Releasing Hormone (GnRH) agonists can reduce menstrual bleeding with hemoglobin recovery. Add-back therapy using tibolone seems interesting since secondary effects encountered with GnRH agonists may be reduced. Levonorgestrel-releasing intrauterine system is proven to reduce increased menstrual bleeding and restore hemoglobin level. Aminoglutethimide and fadrozole have been underevaluated to conclude when letrozole seems as efficient as GnRH agonists to reduce leiomyoma volume and provide less hot flushes. Anastrozol is associated with reduction in leiomyomata volume, pain and menstrual bleeding. Mifepristone reduces the size of uterine leiomyomata, improves symptomatology, but could be associated with development of endometrial hyperplasia. SPRM evaluated in females have shown to improve leiomyoma related symptomatology. Danazol could be useful to reduce leiomyoma related symptoms in short terms. Tamoxifen and raloxifen show modest overall benefit. Because of insufficient data concerning fulvestrant, pirfenidone or interferon, their prescription cannot be recommended in patients with leiomyomata.

Uterine fibroids are the most common benign tumors of the female genital tract. The management of symptomatic fibroids has traditionally been surgical; however, alternative pharmacological approaches have been proposed to control symptoms. To date, gonadotropin-releasing hormone analogs are the only available drugs for the preoperative treatment of fibroids. However, the US Food and Drug Administration recently authorized ulipristal acetate (UPA), an oral selective progesterone-receptor modulator, for the same indication. UPA is a new, effective, and well-tolerated option for the preoperative treatment of moderate and severe symptoms of uterine fibroids in women of reproductive age. According to clinical data, UPA shows several advantages: it is faster than leuprolide in reducing the fibroid-associated bleeding, it significantly improves hemoglobin and hematocrit levels in anemic patients, and it grants a significant reduction in the size of fibroids, which lasts for at least 6 months after the end of the treatment. Furthermore, UPA displays a better tolerability profile when compared to leuprolide; in fact, it keeps estradiol levels at mid follicular phase range, thereby reducing the incidence of hot flushes and exerting no impact on bone turnover. On the grounds of this evidence, the administration of 5 mg/day ulipristal acetate for 3 months is suggested for different patient categories and allows for planning a treatment strategy tailored to meet an individual patient's needs.
