Ultrasound changes in fibroids during relugolix‑estradiol‑norethisterone treatment.
Official title: MyomaS Aspect Transformation at Ultrasound During Relugolix Estradiol Noretisterone Treatment: MySaturn Study
Run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT06953076 · Data updated 2026-11-12
This project will see if relugolix‑estradiol‑norethisterone changes the ultrasound appearance of fibroids in premenopausal women with heavy menstrual bleeding.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are premenopausal women aged 18 or older with symptomatic fibroids causing abnormal uterine bleeding, a myometrial lesion >10 mm on ultrasound, and available digital ultrasound images.
✕Probably not a fit
Patients unlikely to benefit include postmenopausal women, asymptomatic individuals, those with lesions ≤10 mm or ultrasound features suggesting malignancy, and people without usable digital ultrasound images.

What this trial studies
MySaturn is a monocentric ambispective observational project enrolling 111 premenopausal women treated with relugolix‑estradiol‑norethisterone and followed for up to 12 months. The study compares retrospective and prospective digital ultrasound images using MUSA-standard terminology to track changes in lesion size, shape, and vascularity. Symptom scores for bleeding and pain and adverse events are recorded alongside imaging. The goal is to characterize whether medical therapy alters ultrasound features that help distinguish benign fibroids from lesions with suspicious characteristics.
Why it matters
Potential benefit: If successful, this could help clinicians use ultrasound changes to monitor response to relugolix combination therapy and improve noninvasive risk stratification of uterine lesions.
How similar studies have gone: Previous clinical trials have shown relugolix‑estradiol‑norethisterone reduces bleeding and pain in fibroid patients, but its specific effects on ultrasound morphology have not been well characterized prospectively.

Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Age ≥ 18 years. 2. Pre-menopausal status. 3. Ultrasound diagnosis of benign myometrial lesion. 4. Symptomatic patients presenting with abnormal uterine bleeding (menorrhagia/metrorrhagia). 5. Availability of ultrasound images in digital format. Exclusion Criteria: 1. Patient refusal. 2. Age \< 18 years. 3. Postmenopausal women. 4. Myometrial lesion ≤ 10 mm. 5. Myometrial formation suspected of malignancy on ultrasound (e.g., STUMP - Uterine Leiomyosarcoma). 6. Asymptomatic patients with uterine fibromatosis. 7. Personal history of malignant or premalignant uterine neoplasia (e.g., STUMPs, leiomyosarcoma, atypical endometrial hyperplasia, endometrial carcinoma, cervical carcinoma). 8. Patients with ovarian pathology. 9. Patients currently undergoing treatment for another malignancy. 10. Patients lacking available digital ultrasound images or whose image quality is insufficient to adequately characterize the target lesion's ultrasound features
