Metastatic malignant ovarian melanoma--a case report.

Background: Malignant melanomas of the female reproductive system are rare. These are biologically highly aggressive tumors with poor prognosis. Preoperative establishment of the diagnosis is practically impossible.

Reliability and relationship of colposcopical, cytological and histopathological findings in the diagnostic process.

Background/aim: The question about the accuracy of cytology and colposcopy is more and more asked due to false positive and negative findings on the basis of which the decision on biopsy is made. The aim of this study was to examine reliability of biopsies based only on abnormal colposcopical findings, before receiving the results of Papanicolaou (PA) smear, by comparing findings of colposcopical, cytological and histopathological (HP) examinations as well as determining validity of these diagnostic methods.

Methods: The study involved all patients who had their regular colposcopical and cytological examinations in the outpatient department during a two-year period (2009-2010) in the Clinic for Gynecology and Obstetrics, Clinical Center of Serbia, Belgrade.

The utility of human epididymal protein 4, cancer antigen 125, and risk for malignancy algorithm in ovarian cancer and endometriosis.

Background: In women with pelvic mass, cancer antigen 125 (CA125) had not achieved satisfactory sensitivity and specificity in the detection of ovarian cancer, particularly in patients with underlying endometriosis. The aim of this study was to determine the diagnostic potential of human epididymal protein 4 (HE4), the combination of HE4+CA125, and the Risk of Ovarian Malignancy Algorithm (ROMA) for patients with pelvic mass, particularly in differentiating endometriosis from carcinoma.

Methods: A prospective cross-sectional study was conducted at the Clinic for Gynecology and Obstetrics, Clinical Center of Serbia.

Evaluation of adnexal masses: correlation between clinical, ultrasound and histopathological findings.

Background/aim: Concerning the growth of ovarian carcinoma incidence and bad prognosis for malignant forms, early and precise diagnostics is gaining in importance as a condition for precise and appropriate therapy for ovarian tumor masses. The aim of this study was to analyze pre- and postoperative findings of patients with adnexal masses in order to identify factors which could predict the nature and stage of the tumor prior to surgery.

Methods: All patients with adnexal masses who were treated in a 6-month period in the Institute of Obstetrics and Gynecology, Clinical Center of Serbia, (IOG, CCS), Belgrade, had their epidemiologic and gynecologic anamnesis and standard laboratory analyses taken prior to surgery.

Evaluation of the risk malignancy index diagnostic value in patients with adnexal masses.

Background/aim: Ovarian cancer is the leading cause of death from gynecologic malignancies. Risk of malignancy index (RMI) is recommended in assessment of patients with adnexal masses. The aim of this study was to verify the effectiveness of the RMI in the discrimination between benign lesions and malignant adnexal masses in clinical practice.

Expression profiling of the AT2R mRNA in affected tissue from children with CAKUT.

Objectives: Congenital anomalies of the kidney and urinary tract (CAKUT) are common causes of chronic renal failure in children. The angiotensin II receptor type 2 (AT2R) is one of proposed candidate genes for CAKUT, but the expression was never explored in humans. The aim was to establish the AT2R gene expression in human CAKUT concerning -1332A/G polymorphism, which might affect alternative splicing.

Atypical proliferating mucinous tumors of gigantic dimensions.

Unlabelled: BACKGROUND; Ovarian tumors of low malignant potential (LMP) are also known as atypically proliferating tumors. Ovarian tumors of LPM account for approximately 15% of all epithelial ovarian cancers. Mean age of occurrence is 40 years and they are 15-20 cm in diameter.

Simultaneous determination of cefotaxime and desacetylcefotaxime in real urine sample using voltammetric and high-performance liquid chromatographic methods.

Two rapid, accurate and sensitive methods are developed and validated for the quantitative simultaneous determination of cefotaxime (CFX) and its active metabolite desacetylcefotaxime (DCFX) in urine. Based on the previous results which showed the four electron reduction of CFX at approximately -0.5 V, and the new findings that DCFX reduction occurred at more positive potential (-0.

Hysterectomy for Treatment of CIN.

The objective of this investigation was to determine the percentage of microinvasive and invasive cancers found when CIN 3 was treated by hysterectomy. The postoperative histologic findings of all patients with CIN 3 treated by conization or hysterectomy were analyzed. In 295 patients treated by conization, 14 (4.

[Analysis of loss of heterozygosity of the tumor suppressor genes p53 and BRCA1 in ovarial carcinomas].

Background/aim: Among the genes involved in ovarian carcinogenesis, there has been increased interest in tumor-suppressor genes p53 and BRCA1. Both of the genes make control of cell cycle, DNA repair and apoptosis. The p53 is a "genome guardian" inactivated in more than 50% of human cancers, while BRCA1 mutations are found mostly in breast and ovarian cancer.

Krukenberg tumor in pregnancy. The lethal outcome.

Krukenberg tumor refers to gastrointestinal cancer metastatic to the ovaries and its prognosis is uniformly poor. This case report concerns a 38-year-old pregnant woman suffering from abdominal pain and iterative vomiting episodes. She presented with a large abdominopelvic tumor.

[Methods of screening for endometrial cancer].

One of the established strategies for combating cancer is screening the asymptomatic population for premalignant conditions and early-stage disease. The prevalence of endometrial cancer in asymptomatic women is low and the overall prognosis is good because women present in early stage with abnormal bleeding. For all these reasons, screening for endometrial cancer is not recommended in general population.

[Screening methods for malignant ovarian tumors in adult women].

Ovarian cancer is associated with high mortality rate which has improved a little despite therapeutic advances. It causes more deaths than combined cervical and uterine cancer. High mortality is believed to be a direct result of already advanced stage at the time of diagnosis.

[Ovarian cancer after in vitro fertilization].

There is serious concern about cancer risk in women undergoing ovarian stimulation treatment for infertility and longterm safety of these procedures. Association between fertility drugs and ovarian cancer is still controversial. A 30-year-old woman was referred to our institution with the initial diagnosis of an adnexal tumor after in vitro fertilization.
