Active clinical trials for "Leiomyoma"

Uterine leiomyomas, commonly called fibroids, are a major health concern for women of reproductive age. The objectives of the study described herein are to investigate the growth dynamics of uterine leiomyomas in a clinically relevant population of women. We will test the hypotheses that uterine leiomyomas are heterogeneous in terms of their growth characteristics and in their clinical symptoms or outcomes, and that differences in leiomyoma growth dynamics can be discriminated by molecular markers and cellular phenotypes. Participants will include 300 premenopausal women (greater than 18 years old) with at least one uterine leiomyoma. The inclusion criteria for patient enrollment is confirmed diagnosis of leiomyoma by ultrasound. At least one leiomyoma must be equal to or greater than 2 cm in diameter and the uterus must be enlarged to the size typical during the eigth week of pregnancy. After enrollment and informed consent, T1- and T2-weighted magnetic resonance image (MRI) scans will be conducted beginning at the first visit and then at 3, 6, and 12 months. Each patient will have a physical exam, provide urine and blood samples at each MRI visit, and respond to an initial extensive telephone-administered questionnaire followed by abbreviated monthly questionnaire updates. A number of the enrolled women will require surgical intervention (hysterectomy/myomectomy) as standard care. If surgery is an outcome for women enrolled in the study, MRI will be conducted before surgery and the surgical pathologist will map uterine leiomyomas for comparison to MRI. Leiomyoma samples will be analyzed for histopathological and molecular changes correlated with growth. Because hysterectomy and myomectomy are common outcomes in women with leiomyomas, we anticipate tissue will be available from at least 100 of the 300 women in the study. For those women who opt for surgery, we will also administer a brief (less than 5 minute) questionnaire clarifying their reason for electing surgery. Upon completion of data collection, we will be able to compare leiomyoma growth as a function of multiplicity and location; examine the relationship between leiomyoma growth and clinical symptoms or outcome; identify molecular, cellular, and pathological characteristics of leiomyomas with differing growth dynamics; and examine endocrinological parameters and lifestyle factors related to differential growth dynamics of uterine leiomyomas. The data may be used to establish a clinical severity scale and establish diagnostic markers currently not available for uterine leiomyomas.

Uterine leiomyomas are the leading cause of hysterectomy in the United States, accounting for over 200,000 procedures each year. Most epidemiologic studies of uterine leiomyoma show that parity has a protective association with leiomyoma, but the mechanism is not known. Both epidemiologic data and data from an animal model indicate that the protective association is not an artifact resulting from reduced fertility among women with fibroids. We hypothesize that the process of uterine regression following delivery results in loss of small fibroids due to selective apoptosis of transformed cells and the extensive remodeling of the entire uterus.

Determinate the level of vitamin D in blood, and evaluate the prevalence of deficit and insufficiency among patients with diagnosis of uterine fibroids

Study Objective: To evaluate the surgical outcome of laparoendoscopic two-sites myomectomy (LETS-M) and compare the difference between an experienced surgeon and three trainees. Design: A retrospective study. Setting: A university hospital and a tertiary care center. Patients: 204 women underwent LETS-M

Remimazolam is a novel drug approved for induction and maintenance of general anesthesia. This study aims to check the appropriate dose and patient response by administering remimazolam and remifentanil in surgery that does not require a neuromuscular blocking agents.

It is known that volumetric response of leiomyomas following uterine artery embolization correlates well with patients clinical outcome. The aim of this study is to assess diffusion -and perfusion weighted MRI for the prediction of volumetric response following uterine artery embolization in patients with symptomatic leiomyomas.

The purpose of this study is to search for the hereditary (genetic) causes of uterine fibroids. Some women with uterine fibroids may have one or more genes that make them more likely to develop uterine fibroids. We are trying to identify these genes to better understand how and why uterine fibroids develop and to design better treatment options for women with uterine fibroids. This information may also help us to understand and treat other problems that may be caused by these genes.

This study is to reveal any potential advantage of Robot-assisted Laparoscopic Myomectomy (RLAM) over Traditional Laparoscopic Myomectomy (TLM) by comparing the perioperative variables and short-term outcome of RALM and TLM patients.

The purpose of this study is to gain additional information regarding use of Magnetic Resonance Elastography (MRE) for uterine fibroid characterization. In this study, the investigators will use a new noninvasive technology, MRE, to further characterize the elastic properties of the uterine fibroids. To date, very little is known concerning how the tissue composition of the uterine fibroid may affect its treatment with Magnetic Resonance Guided Focused Ultrasound (MRgFUS). In this study, the investigators will use a new noninvasive technology, magnetic resonance elastography (MRE), to further characterize the elastic properties of the uterine fibroids. This information will be gathered during routine magnetic resonance imaging for symptomatic uterine fibroids. It is known that some fibroids with increased T2-signal on Magnetic Resonance Imaging(MRI) can be more difficult to treat. This information will be gathered during routine magnetic resonance imaging for symptomatic uterine fibroids.

This is a retrospective, case-control study of 75 patients having undergone a robotic-assisted laparoscopic myomectomy were compared to patients having undergone myomectomy via laparotomy. Both groups had 3 or fewer fibroids confirmed by pre-operative MRI or on final pathology report. Charts were reviewed for surgical and post-operative variables
