Leiomyoma
Disease Details
Family Health Simplified
- Description
- Leiomyoma, also known as a fibroid, is a benign, smooth muscle tumor commonly found in the uterus.
- Type
- Leiomyoma is a type of benign tumor that arises from smooth muscle tissue, most commonly found in the uterus (uterine fibroids). The genetic transmission of leiomyomas is generally not well-defined as they typically arise sporadically; however, familial cases suggest a possible genetic predisposition, which may involve autosomal dominant inheritance patterns.

### Signs and Symptoms of Leiomyoma (Uterine Fibroids):
1. **Heavy Menstrual Bleeding**: One of the most common symptoms, which may include prolonged periods and passing clots.
2. **Pelvic Pain and Pressure**: Can range from mild discomfort to severe pain, often due to the size and location of the fibroids.
3. **Frequent Urination**: Fibroids can press on the bladder, causing a frequent need to urinate.
4. **Constipation**: Pressure on the rectum can lead to difficulties with bowel movements.
5. **Backache or Leg Pains**: Depending on the location, fibroids can press on nerves, causing pain in the back or legs.
6. **Reproductive Issues**: Can include difficulty conceiving, recurrent miscarriages, or complications during pregnancy.
7. **Enlarged Abdomen**: Large fibroids can cause noticeable swelling or bloating in the lower abdomen.
8. **Pain During Intercourse**: Due to the pressure and position of the fibroids.
Keep in mind that many women with leiomyomas may not experience any symptoms, and when they do, the severity can vary widely. - Prognosis
-
The prognosis for leiomyoma, commonly known as uterine fibroids, is generally favorable. Leiomyomas are benign (non-cancerous) tumors of the smooth muscle layer of the uterus and are most often asymptomatic. When symptoms do occur, they can include heavy menstrual bleeding, pelvic pain, and reproductive issues.
**Nan (not applicable):** As leiomyomas are non-malignant conditions, they do not have a cancer prognosis or staging that would be applicable. The outcome depends on factors such as the size, number, and location of the fibroids, as well as the patient's symptoms and overall health. Many patients experience significant symptom relief through medical management or surgical interventions such as myomectomy or hysterectomy.
Regular monitoring and tailored treatment plans help ensure good management of the condition, with the major focus being on alleviating symptoms and improving the quality of life. - Onset
- Leiomyoma, also known as a fibroid, typically affects women during their reproductive years, generally between the ages of 30 and 50.
- Prevalence
- Leiomyomas, also known as fibroids, are benign smooth muscle tumors commonly found in the uterus. They are quite prevalent, occurring in approximately 20-70% of women of reproductive age. The exact prevalence can vary based on factors such as age, race, and diagnostic methods used.
- Epidemiology
-
Leiomyoma, often referred to as a fibroid, is a benign smooth muscle tumor commonly found in the uterus. Its epidemiology includes:
- **Prevalence**: Leiomyomas are the most common benign pelvic tumors in women, affecting approximately 20-50% of women of reproductive age.
- **Age**: They are most frequently diagnosed in women between the ages of 30 and 40.
- **Ethnicity**: African American women are more likely to develop leiomyomas compared to Caucasian women and tend to develop them at a younger age and with greater severity.
- **Genetics**: There is a familial predisposition; women with a family history of leiomyomas are at higher risk.
- **Hormonal Factors**: Estrogen and progesterone promote the growth of leiomyomas, which is why they tend to shrink after menopause.
"N/A" indicates that the requested section does not contain specific relevant information tailored for "nan." - Intractability
- Leiomyomas, also known as fibroids, are generally not considered intractable. They are benign tumors of the smooth muscle, commonly found in the uterus. Treatment options such as medication, non-invasive procedures, and surgical interventions are often effective in managing symptoms or removing the fibroids.
- Disease Severity
-
Leiomyoma, commonly known as uterine fibroids, are typically non-cancerous growths in the uterus. The severity of leiomyomas can vary widely:
1. **Mild:** Small fibroids that are asymptomatic or cause minimal symptoms. Often found incidentally during routine pelvic exams or imaging.
2. **Moderate:** Larger fibroids or multiple fibroids may cause noticeable symptoms such as heavy menstrual bleeding, prolonged periods, pelvic pain, and frequent urination.
3. **Severe:** Very large or numerous fibroids can lead to severe symptoms including significant pelvic pain, excessive menstrual bleeding leading to anemia, fertility issues, and complications during pregnancy. In such cases, more aggressive treatments may be required.
Severity is influenced by the size, number, and location of the fibroids, as well as the patient's symptomatology and overall health. - Healthcare Professionals

- Pathophysiology
-
Leiomyoma, also known as fibroids, are benign smooth muscle tumors that primarily occur in the uterus. Their pathophysiology involves a series of genetic, hormonal, and environmental factors:
1. **Genetic Factors**: Mutations in genes such as MED12, HMGA2, and alterations in chromosomes can lead to tumor formation.
2. **Hormonal Influences**: Estrogen and progesterone play a crucial role in the growth of leiomyomas. These hormones promote the proliferation and survival of smooth muscle cells in the uterus.
3. **Growth Factors**: Various growth factors, including transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), and insulin-like growth factors, stimulate the growth of fibroid cells.
4. **Extracellular Matrix (ECM) Changes**: Accumulation of ECM components like collagen and fibronectin contributes to the firmness and growth of fibroids.
5. **Inflammatory Pathways**: Chronic inflammation and the subsequent activation of inflammatory pathways can support the development and growth of fibroids.
These factors contribute to the formation and growth of leiomyomas, leading to symptoms such as heavy menstrual bleeding, pelvic pain, and reproductive issues. - Carrier Status
- Leiomyoma, also known as a fibroid, is a benign smooth muscle tumor commonly found in the uterus. It is not typically associated with a carrier status because it is not an infectious or inherited condition in a classic Mendelian sense. Instead, its development is influenced by a combination of genetic, hormonal, and environmental factors.
- Mechanism
-
Leiomyoma, commonly known as a fibroid, is a benign smooth muscle tumor most often found in the uterus.
**Mechanism:**
Leiomyomas arise from the smooth muscle tissue of the uterus. The exact cause is not well understood, but it involves the transformation of normal myometrial cells into tumor cells through various genetic, hormonal, and environmental factors.
**Molecular Mechanisms:**
1. **Genetic Factors:**
- **MED12 Mutations:** Mutations in the mediator complex subunit 12 (MED12) gene are frequently observed in uterine leiomyomas.
- **HMGA2:** Rearrangements involving the high-mobility group AT-hook 2 (HMGA2) gene are also implicated.
- **FH Mutations:** Defective fumarate hydratase (FH) gene can also be a contributing factor.
2. **Hormonal Influence:**
- **Estrogen and Progesterone:** These hormones promote the growth of leiomyomas. Estrogen, in particular, stimulates the proliferation of smooth muscle cells, while progesterone supports the accumulation of extracellular matrix.
3. **Growth Factors and Signaling Pathways:**
- **Transforming Growth Factor-beta (TGF-β):** This cytokine promotes fibrosis and cellular proliferation in leiomyomas.
- **Estrogen Receptor (ER) and Progesterone Receptor (PR) Signaling:** Overactivation can lead to increased cell proliferation and survival.
- **EGF and IGF Pathways:** Epidermal Growth Factor (EGF) and Insulin-like Growth Factor (IGF) signaling also contribute to cellular proliferation and growth.
4. **Extracellular Matrix (ECM) Production:**
- Leiomyomas often exhibit increased ECM components such as collagen, fibronectin, and proteoglycans, contributing to the dense and fibrous nature of these tumors.
Overall, the development of leiomyomas involves a complex interplay of genetic mutations, hormonal regulation, and growth factor signaling, culminating in the abnormal growth of smooth muscle cells. - Treatment
-
Treatment options for leiomyoma (uterine fibroids) include:
1. **Medications**:
- **Gonadotropin-releasing hormone (GnRH) agonists**: Reduce estrogen and progesterone to shrink fibroids.
- **Progestin-releasing intrauterine device (IUD)**: Reduces heavy bleeding.
- **Tranexamic acid**: For heavy menstrual bleeding.
- **Nonsteroidal anti-inflammatory drugs (NSAIDs)**: For pain relief.
- **Oral contraceptives**: Help control menstrual bleeding.
2. **Minimally Invasive Procedures**:
- **Uterine artery embolization (UAE)**: Blocks blood flow to fibroids, causing them to shrink.
- **MRI-guided focused ultrasound surgery (FUS)**: Uses high-frequency sound waves to destroy fibroid tissue.
3. **Surgical Options**:
- **Myomectomy**: Surgical removal of fibroids, preserving the uterus.
- **Hysterectomy**: Complete removal of the uterus, only definitive solution.
4. **Non-Surgical Options**:
- **Watchful waiting**: Monitoring fibroids without active treatment, usually for small and asymptomatic cases. - Compassionate Use Treatment
-
Leiomyomas, commonly known as uterine fibroids, are non-cancerous growths in the uterus. Regarding compassionate use, off-label, or experimental treatments:
1. **Compassionate Use Treatments**: Compassionate use programs allow patients with serious or life-threatening conditions to access investigational treatments outside of clinical trials. For leiomyomas, this might include experimental drugs or therapies not yet approved by regulatory authorities. It's usually considered when standard treatments have failed, are not suitable, or no alternatives exist.
2. **Off-label Treatments**: Physicians sometimes use medications off-label to treat leiomyomas. These could include:
- **Gonadotropin-Releasing Hormone (GnRH) Agonists**: Used to shrink fibroids and decrease bleeding.
- **Aromatase Inhibitors**: Like Letrozole, to reduce estrogen levels, potentially decreasing fibroid size.
- **Selective Progesterone Receptor Modulators (SPRMs)**: Such as Mifepristone or Ulipristal Acetate, to control symptoms and reduce fibroid size.
3. **Experimental Treatments**: New approaches are continually being researched. These might include:
- **MRI-guided Focused Ultrasound Surgery (FUS)**: Non-invasive procedure using ultrasound waves to destroy fibroid tissue.
- **Embolization Agents**: Research into newer agents for Uterine Artery Embolization (UAE) to block blood supply to fibroids.
- **Gene Therapies**: Investigational treatments targeting specific genetic markers associated with fibroid development.
Patients considering these options should consult with a healthcare provider to understand the potential benefits and risks. - Lifestyle Recommendations
-
Leiomyoma, also known as uterine fibroids, are noncancerous growths in the uterus. Here are some lifestyle recommendations that may help manage the symptoms and overall impact:
1. **Diet**: Maintain a balanced diet rich in fruits, vegetables, and whole grains. Consider reducing red meat and high-fat dairy products, which have been linked to fibroid growth.
2. **Exercise**: Regular physical activity can help maintain a healthy weight, which may reduce the risk and symptoms of fibroids.
3. **Stress Management**: Practice stress-reduction techniques such as yoga, meditation, and deep-breathing exercises, as stress may exacerbate symptoms.
4. **Avoid Alcohol and Caffeine**: These substances can potentially worsen fibroid symptoms, so it is best to minimize their intake.
5. **Regular Check-ups**: Schedule regular visits with your healthcare provider to monitor fibroid growth and discuss any new symptoms.
6. **Stay Hydrated**: Drink plenty of water to help alleviate bloating and other symptoms.
Implementing these lifestyle changes can help manage fibroid symptoms, but always consult with a healthcare professional for personalized advice and treatment options. - Medication
-
For leiomyoma (uterine fibroids), medications can help manage symptoms. Commonly prescribed medications include:
1. **Gonadotropin-releasing hormone (GnRH) agonists**: These drugs can shrink fibroids by inducing a temporary menopause-like state.
2. **Progestin-releasing intrauterine device (IUD)**: This can relieve heavy bleeding and pain, although it won't shrink fibroids.
3. **Nonsteroidal anti-inflammatory drugs (NSAIDs)**: These can help reduce pain but not bleeding or fibroid size.
4. **Tranexamic acid**: This medication reduces heavy menstrual bleeding.
5. **Oral contraceptives**: These can help control menstrual bleeding and pain.
6. **Selective progesterone receptor modulators (SPRMs)**: These are newer medications that can reduce fibroid size and control bleeding.
The choice of medication depends on the symptoms, size and location of the fibroids, and whether the patient plans to have children. Always consult with a healthcare provider for a personalized treatment plan. - Repurposable Drugs
-
Leiomyomas, also known as uterine fibroids, are benign smooth muscle tumors of the uterus. The term "repurposable_drugs" refers to medications that are approved for other conditions but could be used to treat leiomyoma. Here are some repurposable drugs for leiomyomas:
1. **Gonadotropin-releasing hormone (GnRH) agonists:** Originally used for prostate cancer or endometriosis, these can reduce the size of fibroids by lowering estrogen levels.
2. **GnRH antagonists:** Often used for conditions like endometriosis, they also work by reducing estrogen levels, which can shrink fibroids.
3. **Selective progesterone receptor modulators (SPRMs):** Originally used for emergency contraception, some SPRMs like ulipristal acetate can reduce fibroid size and symptoms.
4. **Progestins:** These are used in hormonal contraceptives and can also help manage the symptoms of fibroids.
5. **Aromatase inhibitors:** Used in breast cancer treatment, these drugs can lower estrogen levels and potentially reduce fibroid size.
6. **Nonsteroidal anti-inflammatory drugs (NSAIDs):** While primarily used for pain relief, they can help manage the pain associated with fibroids.
These options provide a non-surgical approach to managing the symptoms and size of leiomyomas. - Metabolites
-
Leiomyomas, also known as fibroids, are benign smooth muscle tumors most commonly found in the uterus. Metabolites often studied in relation to leiomyomas include:
1. **Estrogen**: Elevated levels can promote the growth of fibroids.
2. **Progesterone**: Similarly, high levels can stimulate fibroid growth.
3. **Prostaglandins**: Associated with inflammation and pain in fibroid patients.
4. **Glycosaminoglycans**: Elevated in leiomyomatous tissues.
5. **Growth Factors**: Such as transforming growth factor-beta (TGF-β) and insulin-like growth factor (IGF), usually found at higher levels in leiomyomas.
These metabolites play significant roles in the pathophysiology and symptomatology of leiomyomas. - Nutraceuticals
-
There is currently limited evidence to support the use of nutraceuticals specifically for leiomyoma (uterine fibroids). Some studies suggest that certain dietary supplements and herbal remedies may help manage symptoms or potentially influence fibroid growth. These may include:
1. **Vitamin D**: Some research suggests that vitamin D may help inhibit fibroid growth.
2. **Green Tea Extract (EGCG)**: Epigallocatechin gallate, a compound found in green tea, has been studied for its potential anti-fibroid effects.
3. **Curcumin**: Found in turmeric, curcumin has anti-inflammatory properties that may benefit fibroid management.
However, more rigorous clinical trials are necessary to confirm the efficacy and safety of these nutraceuticals in treating leiomyomas. Always consult a healthcare provider before starting any new supplement regimen. - Peptides
- Leiomyoma, commonly known as uterine fibroids, are benign smooth muscle tumors of the uterus. While the use of peptides in the treatment of leiomyoma is an area of ongoing research, there is no standard peptide-based therapy currently established for this condition. Similarly, nanotechnology in the form of nanoparticles is being explored for potential use in targeted drug delivery systems for leiomyoma, but this remains primarily in the experimental stages. Current standard treatments include medication to manage symptoms and surgical options like myomectomy or hysterectomy.
