One of the main complaints of women with symptomatic fibroids is abnormal uterine bleeding, which is characterized by heavy blood loss. Also, these patients may experience acute or chronic pelvic pressure as the tumors enlarge, degenerate or twist. Furthermore, symptoms such as urinary frequency and urgency, and constipation may be observed. These are attributed to compression of bladder and intestines, respectively. In fact, large fibroids can reflect in abdominal fullness distorting the abdomen. Very large leiomyomata can project an outward appearance resembling that of pregnancy [18]. 

The size, number, and location of fibroid(s) contribute to the likelihood of a symptomatic clinical picture. That being said, many are actually small and symptomatic. Also, they can shrink or enlarge.

Any woman with increased uterine bleeding warrants a comprehensive history including detailed information about menstrual and bleeding pattern and quantity. Also, they should be assessed for anemia through history and exam findings. In addition, a bimanual exam is very important. A clinician may notice an enlarged uterus and/or palpate actual fibroids (if located on the outer uterus).

In patients with heavy bleeding (acute or chronic) and/or symptomatic anemia, obtain complete blood count to assess hemoglobin and hematocrit. Other laboratory work may be indicated as well.

Imaging is a key component of the workup. Vaginal and abdominal ultrasonography is the imaging of choice. Other modalities include sonohysterography, hysteroscopy, and MRI. Sonohysterography and hysteroscopy may be useful to visualize submucosal fibroids but they are invasive [19]. MRI can be beneficial in surgery planning since it provides precise mapping although images of the fibroids may be limited since they share attenuation features as the myometrium. Calcifications are also usually seen on CT.

There are numerous treatment options for women with symptomatic fibroids. These include both surgical and nonsurgical interventions. When planning management with the patient, a clinician should consider the severity of symptoms, whether the patient wants to seek treatment and which intervention she prefers. The clinician should determine whether the patient has completed childbearing, if she is seeking fibroid treatment for fertility purposes, whether she has had previous surgeries, and if the patient has any contraindications to surgery or medical therapy. Many patients will have comorbidities such as hypertension, diabetes mellitus or obesity which can influence the decision making. All of these factors will help clarify the best treatment plan for the patient.

Surgical interventions

Hysterectomy is typically the treatment for women who do not want to preserve childbearing. If the uterus is removed, the patient avoids recurrent fibroids [20]. This can be performed laparoscopically or abdominally. The former is minimally invasive.

There are uterine sparing interventions that are available for women whether they seek to protect their fertility or not [21]. Black women are found to favor this option [22]. Myomectomy involves resection of fibroids, which can debulk the uterus and improve bleeding. However, there is a risk of recurrence. In fact, 10 to 25% will needed additional fibroid surgery. Endometrial ablation an intra-uterine procedure that removes the uterus lining. While this does not remove or minimize the fibroid(s), it may reduce or stop bleeding altogether. Women who undergo ablation should not have future pregnancies.

Drug treatments

There are various drug options available for those who are poor surgical candidates or opt for medications. Nonsteroidal anti-inflammatory drugs (NSAIDs) are beneficial for alleviating cramps and heavy flow. In addition, gonadotropin-releasing hormone analogue (GnRH) therapy may be an alternative to surgery since it mimics a menopausal state and helps shrink the fibroids. Treat underlying anemia with iron supplements and monitor for improvement. 

Malignancy

Uterine leiomyomas are typically benign. They rarely undergo malignant transformation and develop into sarcomas. In fact, the exact number that do is not clear since fibroids are very common unlike sarcomas, which may emerge de novo. Estimated incidence is as low as 0.2%.

Fertility

While most women with fibroids do not experience fertility issues, the location of these tumors can affect reproduction. For example, fibroids in the uterine cavity can compromise the ability to conceive. In fact, they may cause miscarriages. Surgical resection of this type can result in successful fertility. Leiomyomata on the outer wall of the uterus mildly reduce fertility. However, surgical removal does not necessarily improve fertility. Fibroids do not usually result in pregnancy complications, but large fibroids greater than 5cm may.  

While the cause of fibroids has not been fully elucidated, it seems that they arise from a unicellular origin [1]. Furthermore, monoclonal proliferation of smooth muscle cells is seen histologically. The composition of these benign tumors are smooth muscle and fibrous tissue.

Some women may have predisposing genes [2] [3]. There may be a genetic component in tumor development as mutations in uterine muscle have been suggested [4]. But there is a multifactorial component promoting the growth of leiomyomata.

Reproductive and environmental factors are linked to the risk of developing fibroids. For example, higher parity [5] [6] and the use of progestin only injectable contraceptives are factors associated with a reduced risk [5] [6] [7]. Conversely, early menarche and the initiation of oral contraceptives prior to 16 years of age are correlated with a greater risk of forming fibroids [5] [6] [7].

Dietary risk factors also exist. A decreased risk is found in patients who incorporate a diet rich with fruits, vegetables, and low fat dairy [8]. A high body mass index (BMI) elevates risk [9] and has been observed in patient with fibroids.

Fibroids are the most common tumors in the female reproductive tract. Approximately 70% of women will have uterine fibroid(s) by the age of 45 years. 

Race

Increased incidence of fibroids in black women has been demonstrated [10]. Furthermore, black women exhibit bigger and more symptomatic fibroids than white women [11] [12] [13] [14] [15]. 50% of black women and 25% of white women experience symptoms.

Risk factors

Women with hypertension [16] and high BMI are observed to be at greater risk of fibroid formation.

Protective factors

Parturition and cigarette smoking are associated with decreased risk.

These benign tumors emerge during reproductive age as evidenced by a complex interplay between estrogen and progesterone on the influence of fibroids. They develop and grow during fertility years but regress during menopause. Comparison of estrogen and progesterone receptors on fibroid cells and uterine cells showed that cells of the former exhibit more hormone receptors, hence they have a capability to increase in size [17]. In addition to these two hormones, insulin like growth factor (IGF-1) [4] and growth hormone also contribute to the development of leiomyomata.

Fibroids are categorized according to their location in the uterus. In order of decreasing frequency, they are called: subserosal, intramural, and submucosal fibroids. Subserosal fibroids may be pedunculated. In addition, this type is found on extrauterine sites. Generally, any type can undergo changes such as degeneration, atrophy, hemorrhage, calcification, or fibrosis.

There are varying sizes that range from very small to extremely large. Sometimes, fibroids develop in other parts of the reproductive tract such as the broad ligaments, fallopian tubes, or even cervix.

Dietary modifications may help reduce the risk of developing leiomyomata. One study showed that intake of pork and beef is associated with these tumors whereas vegetables provided protection [8]. Furthermore, food with a high glycemic index (GI) such as white rice, white breads, donuts and others elevate serum glucose level. This leads to the increase in IGF-1. Note from earlier discussion that this can stimulate fibroid growth.

One study showed that vitamin D plays a role in inhibiting growth, thus insufficient amounts of this vitamin may raise the risk of developing the benign tumors [23]. Another study explored the fibroid risk with intake of fruits, vegetables, and carotenoids. The results showed a lower risk in women with higher intake of fruit and retinol [8]. Furthermore, lower dairy consumption may be associated with higher risk [24]. 

Modifying diet by consuming vegetables, fruits, and dairy products can reduce the risk of fibroid formation but additional benefits include potential weight loss and improvement in hypertension, thus addressing other risk factors. 

Uterine leiomyomas (or uterine fibroids) are the most common tumors in the female genital tract. They are benign and rarely become malignant sarcomas. Fibroids are composed primarily of smooth muscle as well as fibrous tissue. In fact, they basically grow from the uterine muscle.

While genetic mutations have been associated with development of this benign tumor, the cause is likely multifactorial. There are established risk factors such as black race, obesity, hypertension, nulliparity, and family history.

Fibroids are under the influence of estrogen and progesterone and hence occur during reproductive years. While many leiomyomata are small and asymptomatic, an increase in size and number of the benign tumors tends to cause symptoms. The clinical presentation consists of abnormal uterine bleeding, pelvic pressure, urinary and/or abdominal symptoms.

There are surgical and drug therapies available to treat symptomatic women. The management is tailored for each patient since medical and personal factors play in role in the decision making.

Uterine fibroids, also called uterine leiomyomas, are benign tumors that arise from the muscle of the uterus. They usually do not become malignant. Most women will have these tumors as they are very common in women of reproductive age. In fact, they are found in about 70% of women by age of 45. There are risk factors that increase the possibility of developing fibroids such as obesity, black race, never had children, positive family history, and having high blood pressure.

Many fibroids are small and do not produce symptoms. Patients with large and/or many fibroids have a higher chance of having symptoms. The biggest complaints include heavy bleeding, increased urinary frequency and/or urgency, constipation, abdominal fullness, and pelvic pressure or pain.

Diagnosis is done through an ultrasound that is performed vaginally and abdominally. Also, your doctor may be able to feel the fibroid(s) and diagnose this during a pelvic exam. 

There are a number of ways to treat fibroids that cause symptoms. In women who have completed child bearing, they can opt for a hysterectomy, which is a surgery in which the uterus is removed. The surgery could be done with minimal invasiveness. Women who want to keep their uterus and/or preserve fertility can have other procedures such as a myomectomy, which is removal of the fibroid. 

For those are not good candidates for surgery or just do not want it altogether, there may be drug therapies that can help shrink the fibroids. The patient and her doctor will discuss all appropriate options and together decide what the best plan is.
