Aims: To investigate whether the presence of serous tubal intraepithelial carcinoma (STIC) is associated with clinical outcomes in a nonselected (unknown BRCA status) cohort of patients with a high-grade serous carcinoma (HGSC) of the ovary, fallopian tube, and peritoneum.
Settings And Design: A prospective case-series with planned data collection.
Subjects And Methods: The study was conducted in a total of 131 patients, who underwent primary cytoreductive surgery between 2007 and 2012.

Objective: We aimed to analyze variables affecting lymph node (LN) involvement and to assess the need for systematic lymphadenectomy in patients with endometrial cancer (EC).
Materials And Methods: A single centre retrospective analysis was conducted in a total of 128 consecutive patients with EC who underwent systematic pelvic or combined pelvic and paraaortic lymphadenectomy between 2009 and 2012. Mann-Whitney U, chi-square, and Fisher's exact test were used for univariate analyses when appropriate.
Objective: Inter-observer differences in the diagnosis of HPV related cervical lesions are problematic and response of gynecologists to these diagnostic entities is non-standardized. This study evaluated the diagnostic reproducibility of "cervical intraepithelial neoplasia" (CIN) and "squamous intraepithelial lesion" (SIL) diagnoses.
Material And Method: 19 pathologists evaluated 66 cases once using H&E slides and once with immunohistochemical studies (p16, Ki-67 and Pro-ExC).
Potential application of elastic light single-scattering spectroscopy (ELSSS) for differentiating high-grade squamous intraepithelial lesions (HSIL) from non-HSIL tissues was investigated. An ELSSS system was used to acquire spectra from cervix tissues. A single-fiber optical probe with a diameter of 100 μm was used for both delivery and detection of white light to and from the cervix tissue.

In this international study we estimate accuracy and precision of EIN diagnosis among 20 reviewing pathologists in different practice environments, and with differing levels of experience and training. Sixty-two endometrial biopsies diagnosed as benign, EIN, or adenocarcinoma by consensus of two expert subspecialty pathologists were used as a reference comparison to assess diagnostic accuracy of 20 reviewing pathologists.

To identify circulating tumor-derived proteins, mice were immunized with concentrated culture medium conditioned by human breast cancer cells. Antibodies generated by hybridomas were screened against conditioned media from both normal epithelial cells and tumor cells.

Methods: Expression of HIF-1alpha VEGF, and GLUT-1 were analyzed by immunohistochemistry and microvessel density (MVD) was determined by CD 34 immunostaining in 100 endometrioid type endometrial adenocarcinoma, FIGO Stages I-IV.
Results: High expression of HIF-1alpha, VEGF and GLUT-1 were significantly more prevalent in advanced stages than early stages (p<0.
Purpose: Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) selectively induces apoptosis in cancer cells but not in normal cells, and a number of clinical trials have recently been initiated to test the safety and antitumoral potential of TRAIL in cancer patients. Four different receptors have been identified to interact with TRAIL: two are death-inducing receptors (TRAIL-R1 [DR4] and TRAIL-R2 [DR5]), whereas the other two (TRAIL-R3 [DcR1] and TRAIL-R4 [DcR2]) do not induce death upon ligation and are believed to counteract TRAIL-induced cytotoxicity. Because high levels of DcR2 expression have recently been correlated with carcinogenesis in the prostate and lung, this study investigated the importance of TRAIL and TRAIL receptor expression in breast cancer patients with invasive ductal carcinoma, taking various prognostic markers into consideration.

Gene product KIT overexpression has been shown in a number of different neoplasms, particularly in mastocytosis and gastrointestinal stromal tumours (GIST). The morphologic similarity of uterine mesenchymal tumours and GIST, and the presence of KIT protein in normal uterine tissue, suggests that uterine sarcomas may have the same c-kit overexpression.

In the present case report we describe this very uncommon occurrence in the ovary of a 50-year-old woman. The patient suffered abdominal distention and was referred to the state hospital where a 5x3 cm multilocular cystic lesion was observed on abdominal CT.

An important subgroup of adhesion molecules is the superfamily of cadherins, which takes part in cell recognition and differentiation during development. To our knowledge only one study describing N-cadherin expression in developing human brain has been performed so far. Our aim is to identify N-cadherin expression to establish a relationship between its expression and function in human cerebral cortex during prenatal development.

A wide-based polypoid tumor that was localized at the right wall of the distal trachea was observed over 3 cm from the carina by flexible bronchoscope. Computerized tomography showed an intraluminal soft tissue density mass in the trachea.

Deletions in these genes are thought to be pathogenetically involved in some cases of male infertility associated with azoospermia or oligozoospermia.

Aim: To assess the effectiveness of post-partum placental biopsy and frozen section evaluation in diagnosing pregnancy disorders.
Study Design: Between January and July 1998, biopsies were carried out on 100 newly delivered placentas. Biopsies were carried out using a 14-gauge needle, and frozen section evaluations were reviewed.
Recently, considerable attention has been focused on the role of the small heat-shock protein group hsp27, hsp70 and hsp90 in the clinical outcome of several malignancies. However, conflicting data exist regarding the prognostic role of hsp27 expression in ovarian carcinoma, and the prognostic significance of hsp70 and hsp90 expression still remains unknown in these tumours. The purpose of this study was to investigate immunohistochemically whether hsp27, hsp70 and hsp90 expression was associated with clinicopathological parameters and survival in 52 epithelial ovarian carcinomas.

Distinction from medullary carcinoma is important because of the difference in biologic behavior of these two neoplasms and LELC of the breast is regarded as an unusual form of lobular carcinoma. We present the case of a 56-year-old female with a breast mass measuring 2 cm in diameter, which was diagnosed as invasive lobular carcinoma with LELC pattern.
