Purpose: We aimed to investigate whether systematic pelvic and paraaortic lymph node dissection delivers any survival advantage in a subgroup of patients with type II endometrial carcinoma and carcinosarcoma.

Methods: We evaluated 135 patients with clinically early-stage (Stage I-II) type II endometrial carcinoma and carcinosarcoma who underwent systematic pelvic and paraaortic lymph node dissection or who did not undergo any lymph node dissection.

Results: Overall survival (OS) and recurrence-free survivals (RFS) were significantly longer in the systematic lymph node dissection group (hazard ratio 0.

Reactive oxygen species (ROS) have been shown to be responsible for inducing DNA damage leading to mutagenesis, carcinogenesis, and cell death if the capacity of the protective antioxidant system is impaired. Endometrial carcinoma is the primary cancer type in the female genital system. The enhanced cell lipid peroxidation and impaired antioxidant enzyme activities observed in patients with endometrial cancer indicate the potential for oxidative injury to cells and cell membranes in such patients.

Our purpose was to evaluate the role of diffusion-weighted imaging (DWI) in the diagnosis of various common pathologies of the uterine cavity, by comparing them with contrast-enhanced MRI findings. One hundred sixty-four patients with lesions in endometrial cavity were included in the study. The patients were grouped in four (one malignant and three benign groups).

Background Many publications have examined the relationship between apparent diffusion coefficient (ADC) values and tumor grade in endometrial cancer. Nevertheless, none were designed to evaluate according to the histopathological type of endometrioid and non-endometrioid tumors. Purpose To evaluate the role of diffusion-weighted imaging (DWI) in the differential diagnosis of endometrioid and non-endometrioid cancer of the uterus, by comparing them with contrast-enhanced magnetic resonance imaging (MRI) findings.

Purpose: The purpose of this study was to review the effect of age and body mass index (BMI) on the prognosis, demographic characteristics, and pathological features of patients diagnosed with endometrial cancer, specifically before menopause.

Materials And Methods: Patients that were diagnosed with endometrial cancer before menopause, were screened retrospectively. Between 1999 and 2011, 163 patients were identified while 40 were excluded.

Purpose: To assess the diagnostic accuracy of endometrial thickness measurements of transvaginal ultrasound (TVUS) in asymptomatic postmenopausal women in the detection of endometrial malignancy.

Methods: A retrospective cohort study in a university hospital was undertaken with 276 consecutive asymptomatic postmenopausal women undergoing dilatation and curettage (D&C) and hysteroscopy for an incidental finding of thickened endometrium (≥4 mm) between 2003 and 2012. Different endometrial thickness cutoff values were tested on the basis of a pathologic report with carcinoma conditions (endometrial hyperplasia with atypia and endometrial carcinoma).

Aim: The aim of the study was to describe clinicopathologic characteristics, survival outcomes and the factors associated with recurrence in patients diagnosed with synchronous primary endometrial and epithelial ovarian cancers.

Material And Methods: In this retrospective study, 50 patients who were diagnosed with synchronous primary endometrial and epithelial ovarian cancers and underwent surgery between 1998 and 2010 were reviewed.

Results: In our study, the median age at the time of diagnosis was 53 years (range 28-79).

Objective: This is a case series and literature review of patients with endometrial serous carcinoma (ESC) in which endocervical curettage (ECC) and CA-125 measurement were utilized as a diagnostic procedure in preoperative staging.

Materials And Methods: The patients were treated in the gynecologic oncology clinic of İstanbul University Faculty of Medicine between January 2005, and January 2015. A total of 37 patients were included in the final analysis.

Purpose: To demonstrate the blood flow profiles of fetuses with cardiac anomalies at the level of Ductus venosus (DV) and Aortic isthmus (AI) to evaluate the effects of fetal cardiac anomalies on these profiles, and how these profile changes contribute to cardiac anomaly screening studies as a marker.

Methods: DV and AI doppler studies were applied to 64 singleton pregnant women with fetal cardiac anomalies and 74 pregnant women with healthy fetuses. DV-PVIV (peak velocity index for veins) for DV and IFI (isthmic flow index) for AI were used.

Lymphangioleiomyomatosis is a very rare disease that primarily affects the lungs. The atypical smooth muscle cells in these tumors stain both with smooth muscle markers and melanocytic markers characteristically like their counterparts in other members of the PEComa family. Extrapulmonary lymphangioleiomyomatosis, especially without pulmonary involvement, is extremely rare.

Background: Presacral teratomas are usually observed in the first two decades of life and have a 50-67% incidence of malignant transformation. Surgery is the treatment of choice.

Case Report: Here, we report the case of 24-year-old female with chronic urinary retention after surgery for a presacral teratoma.

Introduction: Premature ovarian failure (POF) is the cessation of ovarian function before the age of 40. The loss of ovarian function, whether premature or not, has an overwhelming impact on female skeletal health, leading to an increased risk of developing osteoporosis because of the lengthened time of exposure to reduced estrogen. The objective of this study was to compare the implications of premature ovarian failure on bone turnover markers and bone mineral density in patients under the age of 40.

Introduction: Peritoneal tuberculosis (TB) is uncommon in developed countries, although there is an increase in incidence due to the patients with acquired immunodeficiency syndrome and in immigrants from countries with tuberculosis. The aim of the study was to identify characteristic features of peritoneal tuberculosis (TB), which may be useful for the clinical differential diagnosis and management of this deceiving disease.

Materials And Methods: For this retrospective study, 18 patients, who were diagnosed with peritoneal TB were identified after surgery.

Objectives: To compare the effect exerted by oral tibolone or intramuscular 17β-estradiol administration on the expression of ZO-1, occludin, GFAP and c-fos levels in the brain cortex and hippocampus of ovariectomized rats.

Results: Immunostaining for ZO-1 and occludin revealed similar staining patterns between controls and tibolone rats and between controls and E2 rats. When staining in tibolone and E2 rats were compared both for ZO-1 and occludin, staining patterns were again identical.
