Uterine fibroids (leiomyomas) are the most common tumors of the female reproductive tract, occurring in up to 77% of reproductive-aged women, yet molecular pathogenesis remains poorly understood. A role for atypically activated mammalian target of rapamycin (mTOR) pathway in the pathogenesis of uterine fibroids has been suggested in several studies. We identified that G protein-coupled receptor...

uterine leiomyomas/fibroids are the most common pelvic tumors of the female genital tract. the initiators remaining unknown, estrogens and progesterone are considered as promoters of fibroid growth. fibroids are monoclonal tumors showing 40-50% karyo-typically detectable chromosomal abnormalities. cytogenetic aberrations involving chromosomes 6, 7, 12 and 14 constitute the major chromosome abno...

PURPOSE To estimate the prevalence of women diagnosed with uterine fibroids and the associated symptom burden in the US. PATIENTS AND METHODS Responses of women aged 18-54 years, who completed an online survey, were analyzed. Data were weighted based on age, education, race, geographic region, income, and propensity score to derive national estimates of the prevalence of women diagnosed with ...

This study was conducted to investigate the associations between uterine fibroids and lifestyles including diet, physical activity and stress from October 2009 to April 2011 in China. This case-control study composed of 73 women with uterine fibroids and 210 women without fibroids. Uterine fibroid cases were confirmed by ultrasound diagnosis or hysterectomy surgery. Information on women's dieta...

Copyright © 2013 Massachusetts Medical Society Uterine fibroids (leiomyomas) represent the most common tumor in women. These lesions disrupt the functions of the uterus and cause excessive uterine bleeding, anemia, defective implantation of an embryo, recurrent pregnancy loss, preterm labor, obstruction of labor, pelvic discomfort, and urinary incontinence and may mimic or mask malignant tumors...

Background and Objectives Uterine fibroids are a common indication for laparoscopy. Unsuspected sarcoma can pose a serious risk if morcellation is used in the procedure. We sought to determine the clinical factors associated with uterine sarcoma compared with uterine fibroids. Methods We conducted a case-control study of 66 women who had hysterectomy for uterine sarcoma from April 1, 2007, to...

BACKGROUND Uterine fibroids are the most common gynecologic tumors in women of reproductive age yet the etiology and pathogenesis of these lesions remain poorly understood. Age, African ancestry, nulliparity and obesity have been identified as predisposing factors for uterine fibroids. Symptomatic tumors can cause excessive uterine bleeding, bladder dysfunction and pelvic pain, as well as assoc...

Objectives: To investigate the effect of uterine fibroids on pregnancy outcomes. Methods: This case-control study was conducted in the Khartoum Hospital, Sudan, during June 2011 and through May 2012. Cases were pregnant women who have uterine fibroids, diagnosed by ultrasound scan or discovered accidentally during caesarean section. One consecutive pregnant woman who have no uterine fibroids pe...

Fibroid is the commonest benign neoplasm of the uterus in females, composed of smooth muscle with variable amount of fibrous connective tissue, hence named as leiomyoma or fibromyoma. It is the commonest of all pelvic tumours in females, excluding pregnancy; being more common in nulliparous. It can be intra uterine / extra uterine. Extrauterine fibroids though do occur, but are not as common as...

OBJECTIVE To investigate the risk of uterine fibroids and other reproductive risk factors in women with hereditary leiomyomatosis and renal cell cancer (HLRCC). DESIGN Case-control study. SETTING National Institutes of Health, Rockville, Maryland. Patients A family-based case-control study was conducted between July 1, 2004, and June 30, 2006, including 105 women from families with HLRCC as...
