Background: To identify the hub genes related to urothelial carcinoma of the bladder prognosis and to understand their underlying mechanism. Methods: The expression profiles of 18 pairs of urothelial carcinoma of the bladder patient tissue and paired adjacent tissue obtained from the Cancer Genome Atlas were performed. Weighted gene coexpression network analysis was employed to screen gene modules and hub genes with significant differential expressions in urothelial carcinoma of the bladder. The hub genes expression in urothelial carcinoma of the bladder tissues was validated by reverse transcription-quantitative polymerase chain reaction. The overall survival curve and disease-free survival curve of prognostic factor ( LGALS4) were plotted using the Kaplan-Meier method. Furthermore, LGALS4 messenger RNA and protein expression were also assessed in 2 urothelial carcinoma of the bladder cell lines (T24 and 5637) by quantitative reverse transcription–polymerase chain reaction and Western blot. The functions of urothelial carcinoma of the bladder cells with transfected pcDNA3.1- LGALS4 were identified through MTT assay, plate clone formation assay, flow cytometry, and cell migration experiments. Results: LGALS4 was the hub gene of pink module and it was related to prognosis. Higher LGALS4 expression predicted higher probabilities of overall survival and disease-free survival. Overexpression of LGALS4 in urothelial carcinoma of the bladder cells suppressed cell viability and migration but induced apoptosis. Conclusion: LGALS4 played a critical role in the progression of urothelial carcinoma of the bladder and held a promise to be the biomarker for diagnosis and treatment of urothelial carcinoma of the bladder. It predicted good prognosis of urothelial carcinoma of the bladder and restrained the growth and migration of urothelial carcinoma of the bladder cells.

Purpose: To identify subgroups in glioblastoma multiforme (GBM) with different susceptibilities to radio-chemotherapy by p53 protein and Ki-67 expression.Patients and Methods: Thirty-one patients with primary GBM underwent a combined radio-chemotherapy with topotecan. Percentage of cells expressing p53 protein and Ki-67 antigen was determined immunohistochemically. Additionally, the cell density within the tumour tissue was measured.Results: Median percentages of p53 and Ki-67 expressing cells were 4.3% (range = 0–28%) and 12.0% (range = 0–28%), respectively. Dividing the cases into two groups by high or low p53 protein 1-year disease-free survival rates were 13.3% and 23.6%. High or low Ki-67 expression showed one-year disease-free survival rates of 18.8% and 17.1%. Neither p53 nor Ki-67 expression showed a significant correlation with disease-free survival or overall survival. Median cell density was 252 cells/field (range = 42–595). 1-year disease-free survival rates were 14.5% and 21.7% in high and low cell density group, respectively. A significant correlation with progression-free survival was observed, whereas the stratification into two groups revealed no significance. Cell density showed a significant inverse correlation with p53 and Ki-67 immunopositivity.Conclusion:p53 protein and Ki-67 expression seem to be inappropriate for the estimation of prognosis in patients receiving a combined radio-chemotherapy with topotecan.

Background: The aim of this study was to investigate the immunohistochemical expression of ribosomal protein (RP) S6-pS240 in non-special type invasive breast cancer in relation to other prognostic markers and gain new insights to facilitate more individualized treatment. Methods: The following clinical and histopathological parameters of 120 patients were determined: S6-pS240 expression, age, menopausal status, tumor size and grade, TNM stage, Nottingham Prognostic Index (NPI), lymph node stage, estrogen and progesterone receptor (ER/PR) expression, HER2/neu amplification, lymphovascular invasion, and proliferative index as measured by Ki-67. Treatment protocol and disease-free survival were evaluated accordingly. Results: Significant positive correlations were seen between S6-pS240 expression and Ki-67 values (rho = 0.530, p < 0.001), and NPI (rho = 0.370, p < 0.001) and HER2/neu amplification (rho = 0.368, p < 0.001). A negative correlation was found between S6-pS240 and ER/PR expression (rho = 0.362, p < 0.001). Patients with negative RP S6-pS240 expression had significantly longer disease-free survival (log-rank test, p = 0.005). Conclusion: Immunohistochemical analysis of RP S6-pS240 is a valuable additional prognostic marker in patients with invasive breast cancer. Routine use of S6-pS240 immunohistochemistry is recommended.

Introduction: Endometrial adenocarcinoma is characterized by a good prognosis. However, the disease response shows a significant heterogeneity. Treatment of endometrial cancer (EC) is still based on clinico-pathological parameters, which have limited role in risk stratification. There is a need for more determinant markers, such as L1 Cell Adhesion Molecule (L1CAM), to identify patients at higher risk of relapse and tailor a more convenient treatment. L1CAM has a capacity to enhance cell motility and promote tumor invasion in different malignancies. In Egypt, the incidence rate of EC is growing over time. Especially in Elgharbiah governorate (home of this study). L1CAM expression and Ki-67 was reported and compared with other clinico-pathological criteria. Method: Seventy-six female patients of endometrial carcinomas were involved in this prospective study. The patients were treated and followed up at Tanta University Hospitals in the period between January 2015 to April 2019. L1CAM expression and Ki-67 was detected by immuno-histochemical exam and compared with other clinico-pathological criteria. Survival was assessed and compared by Kaplan-Meier curves and log-rank test. Results: Positive L1CAM expression was detected in 17 patients (22.4%) and was significantly correlated with unfavorable prognostic factors such as higher stage and grade ( P= 0.021 and P =0.001 respectively), lympo-vascular invasion ( P <0.001), non-endometroid type ( P <0.027) and Ki-67 ( P= 0.003). Univariate analysis revealed that: positive L1CAM; higher tumor grade; high stage; and non-endometrioid type were significantly associated with shorter disease-free survival (DFS) but no significant correlation was detected between Ki-67 and DFS. In multivariate analysis, positive L1CAM remained statistically significant with DFS [P =0.045; 95%CI (1.028:11.17); HR=3.38]. Conclusion: Our study indicates that L1CAM expression and Ki-67 are significantly associated with poor tumor characteristics. L1CAM is significantly associated with shorter disease-free survival and may be a helpful tool as a part of a simple clinical molecular classification for EC.
