Sonographic Features of Fibroids Before and During Non-surgical Therapy and/or Expectant Management (MYOVASC)

Rationale: 20-30% of women of reproductive age have leiomyomas, causing symptoms like dysmenorrhea and pelvic pain which both effect quality of life.[1-4] The natural behaviour of uterine fibroids is to grow between 7 to 84% in 3 to 12 months.[5-7] Non-surgical options to treat uterine fibroids are non-hormonal or hormonal medical therapies and minimally invasive interventional radiologic techniques. Exogenous hormone exposure including COC, POP or Mirena give in conflicting literature minimal growth to 60% volume shrinkage. [8, 9]] Selective progesterone receptor modulators (SPRM) eg. Esmya and GnRH-analogues intent to reduce fibroids volume after several months; GnRH-agonists provide a 31-63% shrinkage and less frequently applied GnRH-antagonists 14.3 - 42.7%.[10-16] Esmya gives a volume reduction varying between 10 to 48%.[17] Radiological technique like embolization decreases dominant fibroid volume with 40-70%.[1, 18-22] UAE fails in case of devascularized or minimal vascularized fibroids.[23] Ablation techniques show shrinkage up to a maximum of 90% depending e.g. which treatment.[24-41] Clear prognostic models to predict the effect on fibroid related symptoms and volume reduction are lacking. We postulate higher vascularity to be related to 1) larger fibroid growth during the natural course or during exogenous hormonal exposure; 2) more effective shrinkage during progestogens, GnRH-analogues, SPRM and UAE; but 3) less effective after ablation therapy.

Objectives: To study the value of sonographic features including vascularity in the prediction of fibroids' volume change at follow-up during their (1) natural course or (2) long-term use of exogenous hormone exposure; after initiation of (3) SPRM or GnRH-analogues treatment or (4) exogenous hormonal exposure; or after (5) embolization or (6) ablation therapy.

Study design: Observational cohort study during 5 years in the outpatient clinic.

Patientselection: Women ≥18 years with 1 to 3 fibroids with a maximal diameter ≥ 3cm and ≤ 10cm diagnosed on ultrasound examination, planned for expectant or non-surgical management. Study objectives: The primary outcome is volume reduction after 3 to 12 month depending on the study group. The secondary outcome include UFS-QOL, EQ-5D score, PBAC, hemoglobin level, treatment failure rate and (re)intervention rate.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: No risks are associated with the participation of this observational study since the outcome measures include vaginal ultrasound, questionaires and a hemoglobin test. These measurements are also applied in daily practice, the burden for the patient is time. Extra in the context of the study are questionnaires which last a maximum of 5-15 minutes. The treatment considering the fibroid(s) is independent of this research.
