Uterine leiomyomas are the most prevalent benign tumor type in women of reproductive age and are one of the most common indications for hysterectomy. The expression of five angiogenic factors, adrenomedullin (ADM), vascular endothelial growth factor (VEGF), acidic fibroblast growth factor, basic fibroblast growth factor, and platelet-derived endothelial cell growth factor/thymidine phosphorylas...
BACKGROUND High-intensity focused ultrasound (HIFU) is a highly precise medical procedure used locally to heat and destroy diseased tissue through ablation. This study intended to review HIFU in uterine fibroid therapy, to evaluate the role of HIFU in the therapy of leiomyomas as well as to review the actual clinical activities in this field including efficacy and safety measures beside the pub...
Background: Uterine leiomyomas (fibroids) are now known to be highly variable in their clinical behavior and biologic basis. However, the approach to leiomyomas and their effect on fertility, miscarriage and pregnancy complications has been based on location alone. Materials and Methods: This talk with bring together published information on the effect of leiomyomas on reproductive performance ...
Cell proliferation and apoptosis in uterine leiomyoma were investigated during therapy with GnRH agonist (GnRHa). Patients with uterine leiomyomas were injected with 3.75 mg GnRHa (depot leuprolide acetate) at intervals of 4 weeks and underwent hysterectomy or myomectomy at the 2nd, 4th, 8th, 12th, or 16th week of GnRHa therapy. Tissue sections of leiomyomas from these patients and from control...
It is commonly thought that uterine leiomyomas result from hyperstimulation of myometrium by ovarian hormones. Some observations suggest that cytokines and growth factors are intermediate elements through which the ovarian hormones may exert their growth-stimulatory effects on leiomyomas. Human myometrium and uterine leiomyomas of various weights were homogenised and extracted with 1 M acetic a...
OBJECTIVE Uterine abnormalities, such as leiomyomas, endometrial polyps, and adenomyosis, are often clinically associated with irregular uterine bleeding. These abnormalities can have similar B-mode characteristics but require different treatment. The objective of this study was to develop diagnostic techniques based on ultrasound strain imaging that would allow in vivo visualization and charac...
PURPOSE The purpose of this study was to evaluate the rate of leiomyoma recurrence after uterine artery embolization (UAE) for symptomatic uterine leiomyomas. MATERIALS AND METHODS A prospective study of UAE of uterine leiomyomas has been ongoing at the authors' hospital since 1997. The recurrence rate was assessed in June 2002. Vascular access was obtained via the right common femoral artery...
BACKGROUND Clinical observations indicate that leiomyomas occur more frequently in African Americans compared to other ethnic groups with unknown etiology. To identify the molecular basis for the difference we compared leiomyomas form A. Americans with Caucasians using genomic and proteomic strategies. METHODS Microarray, realtime PCR, 2D-PAGE, mass spectrometry, Western blotting and immunohi...
Leiomyomas and schwannomas of the gastrointestinal tract (GIT) are mainly comprised of spindle-shaped tumor cells and should always be differentiated from gastrointestinal stromal tumors (GISTs). Mast/stem cell growth factor receptor Kit (KIT) and discovered on GIST-1 (DOG1) are well-known diagnostic markers for the detection of a GIST by immunohistochemical staining. The aim of the present stu...
We used a PCR-based subtraction method, representational difference analysis of cDNA (cDNA--RDA), to identify genes with a higher expression in leiomyomas in comparison with the corresponding myometrium during the proliferative phase of the menstrual cycle. Increased expression of the genes for pregnancy-associated plasma protein A (PAPPA), tomoregulin, cellular retinoid acid binding protein 1 ...
