Fifteen women with symptomatic uterine myomas, diagnosed by clinical examination and confirmed by pelvic ultrasonography, were treated with intranasal ir..sufflation of Nafarelin acetate, 200 micrograms, twice a day, for a total treatment period of 6 months. Treatment was evaluated with respect to subjective symptoms, changes in myoma size and uterine volume, variations in blood estradiol, FSH, LH and CA 125, and side effects.
The following results were obtained :
1. All patients showed a marked reduction(p<0.001) in uterine volume. Before treatment volume measured 312.3 ± 24.2cm3, after 12 weeks volume was 132.4 ± 40.6cm3, and after 24 weeks it was 123.6±48.3cm3.
2. Blood estradiol and LH levels were decreased significantly(p<0.05) after treatment. The FSH level was decreased, but not significantly.
3. Blood CA 125 levels were increased 6 cases(40.0%) before treatment. The levels were normalized in all 6 cases after treatment.
4. Symptoms of uterine myoma disappeared or decreased.
5. Minor side effects, such as hot flushes, headache, general myalgia and fatigue, and vaginal dryness were encountered frequently although none necessitating discontinuation of treatment.
These data suggest that Nafarelin acetate is useful for the treatment of uterine myoma. However, appropriate indications should be selected in the treatment of uterine myoma because the possible regrowth of uterine myoma after treatment limits the use of GnRH agonist.
