Abstract
OBJECTIVE Lung cancer displays heterogeneity both in the tumor itself and in its metastatic regions. One interesting behavior of the tumor is known as Skip N2 metastasis, which N2 lymph nodes contain tumor cells while N1 are clean. In this study, mRNA levels of epithelial mesenchymal transition (EMT) related genes in skip N2 and normal N2 involvements of non-small cell lung cancer tissues were investigated to evaluate the possible molecular background that may contribute to the pathogenesis of Skip N2 metastasis. MATERIALS AND METHODS Eighty-three surgically resected and paraffin embedded lymph node samples of lung cancer patients were analyzed in this study, which 40 of them were Skip N2. N2 tissues were sampled from 50% tumor containing areas and total RNA was extracted. mRNA levels for 18S, E-cadherin, Vimentin, ZEB1 and SLUG were analyzed via qPCR and E-cadherin and vimentin protein levels via immunohistochemistry (IHC). Bioinformatic analysis were adopted using online datasets to evaluate significantly co-expressed genes with SLUG in lung cancer tissue samples. RESULTS Skip-N2 patients who had adenocarcinoma subtype had better survival rates. Comparative analysis of PCR results indicated that Skip N2 tumor tissues had increased E-Cadherin/Vimentin ratio and ZEB1 mRNA expression, and significantly decreased levels of SLUG. E-cadherin IHC staining were higher in Skip N2 and Vimentin were in Non-Skip N2. TP63 had a strong correlation with SLUG expression in the bioinformatics analyses. CONCLUSION The results indicate that, at molecular level, Skip N2 pathogenesis has different molecular background and regulation of SLUG expression may orchestrate the process.

Abstract
This study aimed to reveal the possible protective effect of dapagliflozin (DAPA) against acute kidney damage due to cyclosporine A (CsA). Thirty-two mice with an eight-week-old Balb\c albino strain were divided into four groups: control group, CsA group, DAPA group, and CsA + DAPA group. On day 9 of treatment, the animals were decapitated, and bilateral nephrectomy was performed. Oxidative stress and apoptosis were evaluated with caspase-3 activity, total oxidant status (TOS), total antioxidant status (TAS), malondialdehyde (MDA), myeloperoxidase (MPO), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax) in the right kidney resection material. The left kidney resection material was evaluated histopathologically. CsA increased caspase-3 activity, Bax, TOS, MDA, TAS, and MPO levels, and the administration of DAPA with CsA significantly reduced this increase in levels (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p < 0.001, and p < 0.001, respectively). CsA decreased Bcl-2 levels, and administration of CsA + DAPA significantly increased Bcl-2 levels compared with only CsA administration (p < 0.001). Additionally, administration of DAPA significantly reduced the histopathological findings (parenchymal inflammation, hyaline cast formation, vacuolization, and lysis of renal tubular cells) caused by CsA. DAPA reduces oxidative stress, apoptosis, and histopathological damage caused by CsA in renal tissue.

Abstract
Primary melanoma of the urinary tract is a very rare and aggressive cancer. It accounts for less than 1% of all the melanoma cases, making it difficult to histopathologically diagnose and manage. We present a retrospective case series of eight primary urinary tract melanoma with clinical, pathological, and molecular findings to add more insight to this challenging disease. These cases were evaluated for histopathological, immunohistochemical, and molecular features of melanoma that were most commonly found in the urethra, followed by those in the bladder and ureter. Identification of nested growth patterns and in situ melanocytic components at cell edges are helpful in the histopathological diagnosis of amelanotic or hypomelanotic tumors. Our results indicate that urinary tract melanoma has several molecular traits, such as gene expression patterns. Genetic mutations may be related to metastasis, as well as provide targets for the management programs.

Abstract
Although the prognostic significance of grade in endometrial cancer is well known, grade 2 cases have not been evaluated separately in most of the previous studies. In this study, we aim to investigate whether the oncologic outcomes of grade 2 endometrioid endometrial carcinomas trend towards grade 1 or 3 tumors. Patients' records and pathological reports were reviewed retrospectively and eligible patients with endometrioid endometrial carcinoma were determined and distributed into 3 groups according to their 1988 International Federation of Gynecology and Obstetrics (FIGO) grade. Groups' characteristics and oncologic outcomes were compared. Differences between grades were tested with z-test and adjusted by Bonferroni method. Kaplan-Meier method was performed for the survival analysis. In total, 776 patients of endometrioid endometrial carcinoma were included in this study. Mean follow-up time was 52 ± 14 months. Patients' mean age was 56.3 ± 10.8 years. Even though grade 2 endometrioid endometrial carcinomas were different from both grade 1 and 3 in terms of the pathological features, survival analyses demonstrated that their oncologic outcomes trended towards grade 1. The grade was determined as an independent prognostic factor for overall survival (OS). The interobserver reproducibility will be improved among pathologists by combining FIGO grade 1 and 2 endometrioid endometrial carcinomas, while prognosis prediction is not likely to be affected.

Abstract
OBJECTIVES Although Hodgkin's lymphoma (HL) is one of the most curable cancers in adult patients, new targets have to be defined in cases resistant to traditional chemotherapy. The preferentially expressed antigen of melanoma (PRAME) is a cancer testis antigen and its expression is very scarce or absent in normal tissues. For this reason PRAME is a promising candidate for tumor immunotherapy. The aim of this study is to understand the correlation of PRAME expression with prognostic factors in HL, to determine the utility of PRAME as a targeted molecule for immunotherapy and to compare real-time polymerase chain reaction (real-time PCR) and immunohistochemistry (IHC) for the detection of PRAME. METHODS In 82 patients, PRAME was studied using real-time PCR and IHC. Data analyses were performed using statistical methods such as t test, Mann-Whitney U test, χ 2 test, Kaplan-Meier method, log-rank test and Cox regression analysis. RESULTS PRAME was detected in 15 (18.3%) patients using IHC and in 8 (9.8%) patients using real-time PCR. A correlation was found between PRAME positivity and higher International Prognostic Score (p = 0.039). PRAME positivity detected using real-time PCR was found to be correlated with shorter disease-free survival (DFS) and overall survival (OS, p = 0.0005). DISCUSSION The demonstration of PRAME especially in histiocytes and Reed-Sternberg cells may provide guidance for immunotherapy. Although PRAME positivity increases the risk for death (3.56), independent risk factors that affected DFS and OS occurred in advanced age and high-risk groups. CONCLUSION Although real-time PCR is sensitive in the detection of PRAME, IHC can be another useful method. Despite the need for studies conducted on larger patient samples, PRAME expression is considered as a poor prognostic parameter in HL.

Abstract
OBJECTIVE To study the role of immuno-histochemistry and T-cell receptor (TCR) gamma gene rearrangement analysis in the diagnosis of mycosis fungoides (MF). METHODS The study design was retrospective, and 73 cases were selected from the archive of the Pathology Department, School of Medicine, Cukurova University, Adana, Turkey, between January 2004 and December 2009. Thirty-nine MF cases with classical histomorphology, 16 cases with suspicious histomorphology for MF as the inconclusive group, and 18 cases with benign inflammatory dermatoses as the control group were involved in the study. The slides were evaluated for the presence or absence of the histopathological criteria for MF. Immunohistochemically, CD3, CD4, and CD8 were performed in all cases, and their counts and CD4/CD8 ratio were noted. Presence clonal TCR gamma gene rearrangement was evaluated by polymerase chain reaction (PCR). RESULTS The histopathological parameters suggestive of MF were epidermotropism (p=0.000), presence of Pautrier microabscess (p=0.004), and atypical lymphocyte (p=0.000). Immunohistochemically, CD4 percentage (p=0.006) and CD4/CD8 ratio (p=0.010) were statistically significant parameters with univariate analysis. Clonality was present in 76.9% of MF cases and 37.5% in the inconclusive group. Four of 6 clonality positive cases in the inconclusive group were diagnosed as MF in rebiopsies. The CD8 percentage was not statistically different between the 3 groups. CONCLUSION In suspicious cases, CD4/CD8 ratio and TCR gamma gene rearrangement can support histopathology in early MF.
