Bcl-XL and Bcl-2 expression in bilharzial squamous cell carcinoma of the urinary bladder which protein is prognostic

Research Abstract
Background: Local pelvic recurrence after radical cystectomy for muscle invasive bilharzial related squamous cell carcinoma accounts for 75% of treatment failures even in organ confined tumors. Despite the proven value of lymphadenectomy, up to 60% of patients undergoing cystectomy do not have it. These factors are in favor of adjuvant radiotherapy reevaluation. objectives: to evaluate the effect of adjuvant radiotherapy on disease free survival in muscle invasive bilharzial related squamous cell carcinoma of the urinary bladder and to test the predictability of radio-sensitivity using the anti apoptotic protein Bcl-XL. Methods: The study prospectively included 71 patients, (47 males, 24 females) with muscle invasive bilharzial related squamous cell carcinoma of the bladder (Stage pT2a-T3N0-N3M0) who underwent radical cystectomy in Assiut university hospitals between January 2005 and December 2006. Thirty eight patients received adjuvant radiotherapy to the pelvis in the dose of 50Gy/25 fractions/5 weeks (Group 1), while 33 patients did not receive adjuvant radiotherapy (group 2). Immunohistochemical characterization for bcl-xL expression was done. Follow up was done every 3 months for 12 to 36 months with a mean of 16 ± 10 months. All data were analyzed using SPSS version 16. Three years cumulative disease free survival was calculated and adjusted to Bcl-XL expression and side effects of the treatment were recorded. Results: The disease free cumulative survival was 48% for group 1 and 29% for group 2 (log rank p value 0.03). The multivariate predictors of tumor recurrence were the positive Bcl-XL expression (odd ratio 41.1, 95% CI 8.4-102.3, p 0.0001) and radiotherapy (odd ratio 0.19, 95% CI 0.05-0.78, p 0.02). With Cox regression, the only independent multivariate predictor of radio-sensitivity was the Bcl-XL expression with odd ratio 4.6 and a p value 0.0001. All patients tolerated the treatment with no life threatening or late complications during the period of follow up. Conclusions: Adjuvant radiotherapy for muscle invasive bilharzial related squamous cell carcinoma of the urinary bladder has potential effectiveness and minor side effects. Moreover, Bcl-XL expression is a valuable tool for predicting those who might not respond to this adjuvant treatment.

Alteration in miRNAs expression in paediatric acute lymphocyticleukaemia: Insight into patients' therapeutic response

Research Abstract
MicroRNAs (miRNAs) revealed themselves as potential tumour markers and play a significant role in the pathogenesis and progression of acute lymphocytic leukaemia (ALL). This work is designed to investigate the expression of miR‐21, miR‐26, miR‐148a, miR‐133b and miR‐24 in paediatric ALL patients in response to treatment. The expression of miRNAs was determined by quantitative reverse transcriptase–polymerase chain reaction (qRT–‐PCR) in 43 paediatric ALL patients (33 treatment responders and 10 non‐responders) compared to 42 healthy controls. miR‐21, miR‐148a, and miR‐24 were found to be significantly (P .05, P .01, P .05; respectively) up‐regulated in ALL patients compared to controls. No statistically significant differences in expression levels of miR‐26a and miR133b were detected in both groups. Concerning treatment, responders are found to have a decreased level of miR‐24 …

Neutropenic enterocolitis in pediatric leukemia patients treated with intensive chemotherapy in Upper Egypt

Research Abstract
Importance: In low resource countries, there has been scarcity of research on the risk factors associated with neutropenic enterocolitis, a serious complication that commonly develops during treatment of cancer patients. Objective: To identify the pattern of intestinal complications in pediatric leukemia patients treated with intensive chemotherapy, including those with neutropenic enterocolitis; to assess the outcome; and to evaluate the risk factors associated with the mortality in these patients. Methods: During the period from June 2015 to December 2016, a prospective study was carried out on pediatric patients diagnosed with acute leukemia who received induction/or re-induction phases of chemotherapy at South Egypt Cancer Institute. Patients with documented episodes of intestinal complications were included in the study. Recovery or death from an episode of intestinal complication was utilized as the primary outcome measure for the study. Using univariable and multivariable methods, potential risk factors associated with mortality were delineated by logistic regression analysis, both for the entire intestinal complications episodes as a whole and for those episodes of neutropenic enterocolitis only. Results: Out of 88 documented episodes of intestinal complications from 77 patients; 58 episodes were identified as neutropenic enterocolitis from 47 patients. In those patients who were having episodes of neutropenic enterocolitis, the presence of abdominal tenderness (OR 4.529, 95%CI 1.062–19.317, P = 0.041); a longer duration of neutropenia (OR 1.215, 95%CI 1.030–1.434, P = 0.021); and hemodynamic instability (OR 17.023, 95%CI 4.095–70.772, P 0.001), were found to be independently associated with worse outcome. Interpretation: In Upper Egypt, the use of intensive systemic chemotherapy during the induction phase of acute leukemia was found to be associated with potentially lethal intestinal complications. A high index of clinical suspicion is warranted.

Prognostic Value of c-Myc Immunohistochemical Expression in Muscle Invasive Urothelial Carcinoma of the Urinary Bladder: A Retrospective Study

Research Abstract
Objective: This study aimed to investigate the immunohistochemical expression of c-Myc in muscle invasive urothelial carcinoma (MIUC) of the urinary bladder and to evaluate the correlation of c-Myc expression with different clinicopathological parameters and outcome, including a relatively new histopathological tumor characteristic that is the growth pattern of tumor invasion. Methods: A total of 66 formalin-fixed and paraffin-embedded sections of MIUC obtained from radical cystectomy specimens were enrolled. The sections were stained with c-Myc antibody using immunohistochemistry technique. Results: Tumor cells showed variability in nuclear c-Myc expression according to the growth pattern of invasion. The median H-score of nuclear expression of infiltrative pattern was significantly higher than that of non-infiltrative pattern (p0.001). Nuclear expression of c-Myc in tumor tissue had a significant association with poor prognostic factors (sarcomatoid variant (p0.001), perineural invasion (p=0.037), lymphovascular invasion (p0.001), lymph node metastasis (p0.001), distant metastasis (p=0.042) and advanced stage grouping (p=0.001). Kaplan Meier survival analysis demonstrated that c-Myc expression could not be significantly correlated with overall survival or disease free survival rates. Conclusion: Nuclear c-Myc seems to have a prominent role in epithelial to mesenchymal transition with consequential in tumor progression and metastasis, while it is not as much useful to predict the clinical behavior of patients with MIUC.
