We examined the association between HNF1B variants identified in a recent genome-wide association study and endometrial cancer in two large case-control studies nested in prospective cohorts: the Multiethnic Cohort Study (MEC) and the Women's Health Initiative (WHI) as part of the Population Architecture using Genomics and Epidemiology (PAGE) study. A total of 1,357 incident cases of invasive e...
Background: Historically the conventional Pap smear has been an effective screening tool for Carcinoma cervix. However the reporting of benign and malignant endometrial cells on Pap smear has remained controversial. There are very few studies addressing the utility of Pap smears in diagnosing endometrial carcinomas. Objective: To rescreen the Pap smears of patients with endometrial adenocarcino...
BACKGROUND The ectopic establishment and progression of endometrial tissue is dependent upon its interaction with and responsiveness to the stimuli present in its new environment. Immune cell-derived cytokines, such as interleukin 1 (IL1), may alone or in concert with estrogens enhance the capability of ectopic endometrial cells to implant and develop into the host tissue. The objective of this...
Endometrial carcinoma is the most common type of gynecological carcinomas. Several biological mechanisms trace the relationship between obesity and endometrial neoplastic risk. In surgical practice, there has been increasing interest concerning a group of cytokines as an independent prognostic factor for aggression and the possible therapeutic impact on the neoplastic process. The high-tech sur...
Objectives: The ABO blood group antigens were found on most epithelial cells and in secretions. In the normal endometrium there is a variable expression of histo-blood group and related antigens suggesting a hormonal regulation. A relationship between ABO blood groups and endometrial cancer has been investigated with contradictory results. In this study we investigated the influence of blood ty...
Chronic inflammation may play an etiologic role in endometrial cancer. Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce inflammatory activity by inhibiting the proinflammatory cyclooxygenase enzymes and, therefore, may decrease cancer risk. However, few studies have examined the association between NSAID use and endometrial cancer. We conducted a prospective study among 72,524 women in the ...
INTRODUCTION The aim was to compare the efficacy of long-acting and short-acting gonadotropin-releasing hormone (GnRH) agonists by long protocol on embryo quality, endometrial thickness and pregnancy rate in in vitro fertilization. MATERIAL AND METHODS In this retrospective study, long-term pituitary downregulation, achieved with long- and short-acting GnRH agonists (GnRHa), was performed for...
Childbearing at an older age has been associated with a lower risk of endometrial cancer, but whether the association is independent of the number of births or other factors remains unclear. Individual-level data from 4 cohort and 13 case-control studies in the Epidemiology of Endometrial Cancer Consortium were pooled. A total of 8,671 cases of endometrial cancer and 16,562 controls were includ...
We have previously shown that corticotrophinreleasing hormone (CRH) inhibits the proliferation of Ishikawa (IK) human endometrial carcinoma cell line through the activation of CRH-R1 receptors. Here, we have further investigated the role of CRH and its type-1 receptor in the control of IK cell function, and we carried out a pilot study in tumor tissues obtained from 19 patients with endometrial...
Endometrial carcinoma is the most common gynecologic cancer, yet the mechanisms underlying this disease process are poorly understood. We hypothesized that Lef1 is required for endometrial gland formation within the uterus and is overexpressed in endometrial cancer. Using Lef1 knockout (KO) mice, we compared uterine gland development to wild-type (WT) controls, with respect to both morphology a...
