What are the treatment options for symptomatic uterine fibroids?

Treatment Options for Symptomatic Uterine Fibroids

The most effective approach to treating symptomatic uterine fibroids involves a stepwise algorithm beginning with medical management for mild symptoms and progressing to minimally invasive or surgical options for more severe or refractory cases, with treatment selection based on symptom severity, desire for fertility preservation, and fibroid characteristics. 1, 2

Medical Management Options

First-Line Treatments

• NSAIDs and estrogen-progestin oral contraceptive pills are recommended first-line medical treatments for reducing bleeding symptoms associated with uterine fibroids 1, 2
• Tranexamic acid provides an effective nonhormonal alternative for patients who cannot use hormonal options or for acute bleeding episodes 1, 2
• Progestin-containing intrauterine devices (IUDs) effectively reduce bleeding symptoms and should be considered for long-term management of fibroid-related bleeding 1, 2

Second-Line Treatments

• GnRH agonists and oral GnRH antagonists effectively reduce bleeding symptoms and significantly decrease fibroid volume by 18-30% 1, 2, 3
• Combination treatment with low doses of estrogen and progestin (add-back therapy) mitigates the hypoestrogenic side effects of GnRH modulators and is FDA-approved for fibroid-related heavy menstrual bleeding 1, 2
• GnRH agonists are particularly useful as preoperative treatment to reduce fibroid size and correct anemia before surgery 4, 3
• GnRH antagonists can be used for longer-term management compared to agonists 3

Surgical Management Options

Uterine-Preserving Procedures

• Hysteroscopic myomectomy is the procedure of choice for pedunculated submucosal fibroids <5 cm, offering shorter hospitalization and faster recovery compared to other approaches 1, 2
• Laparoscopic myomectomy is associated with shorter hospital stays and faster return to usual activities compared to open myomectomy 1
• Both laparoscopic and open myomectomy procedures improve quality of life for up to 10 years 1

Definitive Treatment

• Hysterectomy provides definitive resolution of all fibroid-related symptoms and remains the most common treatment for uterine fibroids in the United States, particularly appropriate for women who have completed childbearing 2, 5

Minimally Invasive Alternatives

• Uterine Artery Embolization (UAE) is effective for patients with fibroids who desire uterus-preserving therapy, improving symptom scores and quality of life for up to 7 years 1, 2
• UAE demonstrates greater reduction in fibroid diameter (53%) compared to laparoscopic uterine artery occlusion (39%) 1
• The reintervention rate after UAE is approximately 7% for persistent symptoms 2
• MR-guided Focused Ultrasound (MRgFUS) can be considered, though it has a higher reintervention rate (30%) compared to UAE (13%) 1, 2
• Radiofrequency ablation of fibroids is another emerging minimally invasive option 5, 6

Treatment Selection Algorithm

For Mild Symptoms with Desire for Future Fertility

• Start with NSAIDs and/or tranexamic acid for acute bleeding episodes 1
• Consider hormonal contraceptives or levonorgestrel IUD for ongoing management 1, 6

For Moderate-Severe Symptoms with Desire for Future Fertility

• Consider short-term GnRH modulators with add-back therapy to reduce fibroid size 1, 3
• For submucosal fibroids <5cm, hysteroscopic myomectomy is recommended 1, 2
• For intramural or subserosal fibroids, laparoscopic or open myomectomy based on size, number, and location 1, 5
• UAE may be considered, though potential impact on fertility should be discussed 1, 2

For Moderate-Severe Symptoms without Desire for Future Fertility

• For short-term symptom control, GnRH modulators with add-back therapy 1, 3
• For definitive treatment, hysterectomy provides complete resolution 2, 5
• For patients wishing to avoid major surgery, UAE offers a uterine-sparing alternative with good long-term outcomes 1, 2

Important Considerations

• Treatment must address both symptom management and potential anemia from chronic bleeding 6
• Iron replacement therapy should be initiated for patients with iron deficiency or anemia 6
• The choice between medical and surgical options depends on fibroid characteristics (size, number, location), symptom severity, and patient preferences regarding fertility preservation 5, 6
• Fibroids tend to return to their pretreatment size about 6 months after discontinuing GnRH analog treatment, making them most appropriate as bridging therapy before definitive treatment 4
