Symptom-free interval after triptorelin treatment of uterine fibroids: long-term results.
An increasing number of publications document regression of fibroids under treatment with gonadotropin releasing hormone (GnRH) agonists. However, recurrence after stopping treatment regularly counterbalances its benefit. We now report on 28 patients with intramural myomas, treated with triptorelin for 4-6 months and followed for 42-56 months. During or shortly after treatment, six patients entered menopause. In this group, a volume reduction of 71% was achieved and no surgery was needed thereafter. In 22 premenopausal women, a 64% decrease of uterine volumes was obtained at the end of treatment; the long-term reductive effect was 31%. When compared with initial values, a significant decrease was observed at the end of treatment (p = 0.0001) and of follow-up (p < 0.0005). In 13 (of 22) premenopausal patients, surgery was needed after triptorelin treatment for permanent control of fibroids. The remaining nine patients were free of symptoms after 42-56 months, having uteri in situ. These two groups differ significantly in pretreatment uterine volume (p < 0.001) and in reduction rate after therapy (p < 0.01), both parameters being higher in patients who finally needed surgery. In conclusion, triptorelin treatment is definitely beneficial in perimenopausal women and in nearly half of premenopausal women, in whom hysterectomy can be prevented. In the other half, surgery is necessary, despite significant volume reduction. These results need to be corroborated on larger groups of patients. More research is needed to explain different responses to treatment in premenopausal patients.
