The advantages of this procedure are a very low morbidity and a very rapid recovery, with return to normal activity in 1 day, but its long-term effectiveness is not yet known. Presently, the procedure is not recommended for women who desire future fertility. See a video about focused ultrasound treatment for fibroids. Uterine fibroid embolization UFE , also known as uterine artery embolization UAE is a radiological alternative to surgery that involves placing a catheter through a small incision in the groin into an artery in the leg and guiding the catheter via x-ray pictures to the arteries of the uterus.
Once there, the catheter is used to deliver agents that block off the blood vessels that feed the uterine fibroids. Specific embolic agents include gelatin sponges, polyvinyl alcohol particles, or tris-acryl gelatin microspheres.
Total radiation exposure, following this procedure is approximately 15 rads, which is comparable to that in one to two computed tomography scans or barium enemas 1 ref. UFE is a minimally invasive technique that allows for quick recovery after the procedure.
Women can have improvement in both their bleeding symptoms and pressure symptoms after UFE. Women also need to have a physical examination and discuss their medical history with an interventional radiologist to determine if they are suitable candidate for a UFE procedure. Advantages over surgery include no abdominal incisions and a shorter recovery time. Complications may occur if the blood supply to your ovaries or other organs is compromised.
The safety of these procedures in women desiring pregnancy has not been demonstrated and is generally not advised for women who want to have children in the future. Despite the major public health impact of leiomyomas, little is known about their cause. Until recently, the steroid hormones estrogen and progesterone were considered the most important regulators of leiomyoma growth. There is abundant evidence that estrogen promotes fibroid growth including the clinical observations that fibroids grow in the presence of high levels of estrogen, such as during the reproductive years, and that they regress in the presence of low levels of estrogen, such as following menopause or during gonadotropin releasing hormone GnRH agonist therapy.
Furthermore, fibroids have higher estrogen concentrations, bind more estrogen, have more estrogen receptors, and convert estradiol a more active form of estrogen to estrone a less active form of estrogen more slowly than normal myometrium.
Progesterone is also thought to play a role in fibroid growth. More specifically, clinical studies suggest progesterone facilitates the growth of fibroids. For example, fibroid size increases during treatment with synthetic progesterones. Combination GnRH agonist and progesterone therapy has been shown to have no effect on uterine volume, in contrast to GnRH agonist therapy alone which has been shown to reduce uterine volume.
The observation that fibroids regress with the antiprogesterone agent, RU, further supports the role of progesterone as a promoter of fibroid growth. Histologically, fibroids from patients treated with progesterone show more cellular growth than those from patients without progesterone therapy. Biochemically, fibroids have higher progesterone receptor concentrations than normal myometrium.
Together, these data suggest that progesterone also enhances fibroid growth. Other hormones such as growth hormone GH and prolactin PRL are also thought to promote fibroid growth, but their role is even less well defined. More recently, growth factors, which are small proteins that affect cell growth, have been shown to mediate the growth-promoting effects of estrogen and to play an important role in the development of fibroid tumors.
Potentially important factors in fibroid growth include transforming growth factor-beta, basic fibroblast growth factor, epidermal growth factor, insulin-like growth factor, and platelet-derived growth factor. For more information about this, please see the article, Leiomyoma-related bleeding: A classic hypothesis updated for the molecular era, on the "Publications" page. Overall, estrogen, progesterone, and growth factors likely promote tumor growth, but only after the initiation of tumor formation.
This initiating event remains unknown, although recent evidence suggests there is a strong inherited component to fibroid development. Indirect evidence for this hypothesis is as follows. First, fibroids are at least twice as common in black women than in white women. Although racial differences in socioeconomic status and access to health care, as well as racial differences in known risk factors for fibroids, may contribute to this finding, two recent studies suggest that these factors do not completely explain the discrepancy.
Secondly, another study found a genetic predisposition for hysterectomy as indicated by a two fold higher twin pair correlation for hysterectomy in identical versus fraternal twins. Thirdly, there exists a rare heritable form of uterine fibroids in association with fibroids of the skin called Reed's syndrome. Finally, a recent Russian studies suggest that women with a family history of fibroids are twice as likely to develop fibroids than women with no family history. Unfortunately, few scientific studies directly examine the genetic component of fibroid development.
For more information about the genetics of fibroids, please see articles published about these genes on the "Publications" page.
Normally, these genes code for proteins that help control cell growth by indirectly regulating DNA transcription. However, mutations in these genes are probably secondary changes in already genetically susceptible cells.
Therefore, it is likely that other gene s crucial for fibroid development exist that have not yet been identified. To this end, the staff at the Center for Uterine Fibroids is studying families with at least one pair of siblings affected by fibroids to search for gene s that predispose women to fibroid development.
For information about this study, including participation, please see, Finding Genes for Fibroids, on the "Current Studies" page. Ultimately, understanding the hormones, growth factors, and gene s involved in the formation and growth of fibroid tumors may lead to innovative, less invasive treatment options. Adenomyosis is a benign disease of the uterus in which components normally limited to the endometrium the thin innermost uterine layer are found within the myometrium the middle muscular layer of the uterus.
The exact prevalence of adenomyosis is not known because the diagnosis can be made only by microscopic examination of uterine specimens obtained during surgery or, less often, during biopsy. The cause of adenomyosis is also unknown. The most widely accepted theory of adenomyosis development postulates that the barrier between the endometrium and myometrium, which normally prevents invasion of endometrial glands and stroma into the myometrium, is compromised allowing invasion to occur.
This process is thought to occur only in the presence of estrogen, however, little scientific evidences exists to support this hypothesis. Adenomyosis most commonly affects women between the ages of 40 and 50 years and is associated with a past history of childbirth. However, the incidence of adenomyosis does not correlate with increasing number of pregnancies.
Adenomyosis is also associated with other uterine disorders. The symptoms of these associated conditions often obscure the diagnosis of adenomyosis. A typical uterus with adenomyosis is boggy and uniformly enlarged. Symptoms of adenomyosis include abnormal uterine bleeding and pelvic pain. The reason for this low percentage of preoperative diagnosis is two-fold; first, many patients with adenomyosis are asymptomatic in the absence of other uterine pathology, and second, the presence of adenomyosis is often overshadowed by associated pathology e.
In this procedure, the cervix is gradually dilated to allow removal of the uterine lining. Pelvic ultrasonography may be suggestive but is not definitive. The usefulness of other imaging studies such as MRI magnetic resonance imaging is currently undetermined.
Areas of adenomyosis do not lend themselves to local surgical excision. The only definitive treatment for adenomyosis, therefore, is total hysterectomy surgical removal of the entire uterus. Synthetic steroid hormones such as progestins are not helpful and may actually increase the level of pelvic pain in some patients.
GnRH gonadotropin releasing hormone agonists have been used in a few cases, resulting in a transient decrease in uterine size, in amenorrhea cessation of menstrual cycling , and even in the ability to conceive. Unfortunately, regrowth of the adenomyosis and recurrence of symptoms are usually documented within six months of cessation of therapy. Endometrial polyps are localized overgrowths of the endometrium innermost uterine layer that project into the uterine cavity.
Such polyps may be sessile broad-based or pedunculated on a narrow stalk and rarely include areas of neoplastic benign or malignant growth. Specifically, adenomatous hyperplasia benign growth of the endometrium and endometrial adenocarcinomas malignant tumors of the glandular component of the endometrium , have been reported in only 0. Endometrial polyps are rare among women younger than 20 years of age.
The incidence of these polyps rises steadily with increasing age, peaks in the fifth decade of life, and gradually declines after menopause. Frederick National Laboratory for Cancer Research.
