Macrophages are the first line of defense in the cellular environment in response to any antigenic or foreign invasion. Since cancer cells express antigenic molecules and create a tumor microenvironment quite different from the normal cellular environment, macrophages will attack this cancer cells as foreign Invaders. However, the cancer cells adept their ability to suppress macrophage activity by secreting compounds/proteins through unknown mechanisms and train these macrophages to aid in tumorigenesis. These macrophages are commonly known as tumor associated macrophages (TAM). In this study, our goal was to find out key regulatory molecules involved in this conversion of cancer-fighting macrophages to cancer friendly macrophages. We used African American(AA) patient derived established human prostate cancer cells along with the human derived macrophages followed by Affymetrix cDNA microarray analysis. Microarray analysis of the PCa cell exposed macrophages revealed appreciable decrease in mRNA expression of several genes associated with phagocytosis process. Aberrant expression of several noncoding RNAs that control the expression of such phagocytosis associated molecules were also evident. Increased expression of oncogenic miR such as, miR-148, 615, 515, 130, 139 and markedly decreased expression of tumor suppressive miR's MiR-3130, let7c,101,103, 383 were noted. Further, TARGET SCAN analysis demonstrated these differential expression of non-coding RNA's causing down regulation of phagocytosis promoting genes elf5A, Meg3, Tubb5, Sparcl-1, Uch-1, Bsg(CD147), Ube2v, GULP, Stabilin 1 and Pamr1. There is an increase of RAP1GAP gene that causes concomitant decrease in the expression of tubulin genes that promote cytoskeletal assembly in forming phagosomes. In addition Ingenuity pathway analysis of the gene expression data also showed upregulation of antiphagocytic genes IL-10, CD 16, IL-18 and MMP-9. Some core canonical pathways showing physiology of cellular signaling obtained by data analyzed by the Ingenuity software is confirmed a very complex mechanism still to be deciphered involved in the biology of TAM formation by which the rogue cancer cells tame their enemies, the macrophages and actually make them their helper cells to survive and propagate in the tumor microenvironment and thus prepare for epithelial mesenchymal transition for future metastasis and cancer stem cell formation and progression.

Background: The pathogenesis of non-Hodgkin lymphoma is a complex process that involves several molecular changes. Alterations in polycomb group proteins as well as Survivin have been described but details are still lacking particularly in T/NK-cell lymphomas. Polycomb proteins have a big role in cell cycle and differentiation. Survivin is another recently recognized player in non-Hodgkin lymphoma.Objective: To study the pattern of Bmi-1 and Survivin in different categories of B- and T/NK- cell non-Hodgkin lymphomas, their association with the clinicopathological parameters, and their impact on the prognosis of non-Hodgkin lymphomas.Material& methods: Immunohistochemical staining was used to study paraffin samples of 267 patients’ biopsies. We used tonsils and reactive lymph node as normal control.Results: Both Bmi-1 and Survivin showed significant upregulation in several subtypes B- (P = .000-.02 for Bmi-1 and .00- .03 forSurvivin) and T/NK cell lymphomas (P= .009-.03 for Bmi-1 and 0.008- 0.009 for Survivin) compared to normal tissue. Significantpositive correlation between Bmi-1 and Survivin was detected in both B- (Co= 0.539**, P = .00) and T - cell lymphomas (Co= 0.560**, P = .000). A statistically significant difference between overall survival and expression of both BMI-1 and Survivin was detected (P = .00 for BMI-1and survivin).Conclusion: Bmi-1 and Survivin show significant upregulation as well correlation with clinicopathological parameters and overall survival of non-Hodgkin lymphomas.

Introduction: To check the impact of the clinical and pathologic features at diagnosis and treatment given, on the outcome of synovial sarcoma in children and adolescents.Methods: Retrospective analysis of patients below 18 years old diagnosed by synovial sarcoma and treated at Children CancerHospital Egypt 57,357 (CCHE) between July 2007 and December 2016. We reviewed Clinical characteristics, pathological information, treatment modalities and survival data.Results: We included thirty one patients with median age at diagnosis was 14.8 years. Initial surgical excision was possible in 10 patients (58.8%) while 5 (29.4%) patients underwent surgical excision after response to preoperative chemotherapy. Two patients had unresectable tumor, showed no response to chemotherapy and received radiotherapy as the only local control therapy. Adjuvant radiotherapy only was given in 2 patients and 5 patients received chemotherapy without local radiotherapy and 10 patients received both modalities. The estimated 5-year overall survival and failure free survival rates for the entire group were 84.4% ± 7.2% and 63.8% ± 9.7% respectively, the 5-year OS and FFS were studied in correlation to age of patient, tumor size, different pathological types, site of the lesion and methods of local control. In patients with tumor size below 5 cm when compared to size more than 5 cm with OS was (100%) in comparison to (79.3 ± 9.3) who underwent complete surgical excision either initial or post chemotherapy as it was 66.7% versus 55.6% for those with gross or microscopic residual (p-value = .38). Also, the 3-year failure free survival was 75% versus 56.3% for those smaller than or equal 5 cm and those larger than 5 cmrespectively (p-value = .3).Conclusion: Increasing number of patients to increase sample size to assess tumor size and complete surgical excision as important prognostic factors as in our study, we found them statistically insignificant. Preoperative chemotherapy can help for delayed excision in patients presented initially with unresectable tumors

Introduction: The aim of this study was to determine whether radiomic features measured at baseline in Magnetic Resonance images (MRI) of acoustic neuromas (AN) can predict Gamma Knife (GK) treatment outcome.Methods: The study was conducted on pre- and post-GK MRI-T2 scans of 32 patients with AN who underwent stereotactic radiosurgery (SRS) for 12 Gy dose. Radiomic features extracted include Intensity, Fractals, Laplacian of Gaussian and textural Co-Occurrence, Run-length (RL), Size Zone, and Neighborhood Gray-Tone Difference matrices (NGTDM) features. Subjects were classified as treatment failures (TF) if tumor volume increased > 10%. Pre- and post-SRS audiology reports were utilized in hearing evaluation.Results: Fifteen subjects (47%) qualified as TFs. In univariate receiver operating characteristic (ROC) analysis, two radiomicfeatures, complexity in NGTDM and run percentage in RL, displayed areas under curves of > 0.65.Conclusion: This initial radiomic study establishes features that illustrates the prognostic ability of the SRS treatment in acousticneuroma. Hearing preservation was achieved in a majority of acoustic neuroma patients treated in Gamma Knife.

Objective: The aim of the study is to assess the physical, financial, emotional and social impact of breast cancer on women in North east Nigeria.Methods: A qualitative transcendental phenomenological study design was adopted, using face-to face unstructured interview to collect data from 22 respondents who were recruited via purposive non-probability sampling technique. The interviews were recorded, transcribed verbatim and further analyzed using thematic analysis method into themes and sub-themes.Results: The result revealed excruciating pains that does not abate completely as the main physical impact, expensive cost of treatment as the major financial impact and crying as the major emotional impact of breast cancer on women. However, been diagnosed with breast cancer had no any consequences on participants’ relationship with spouse or family members.Conclusion: Breast cancer causes pain, makes women to cry and the treatment is very expensive but it does not cause relationship problems. There is therefore the need for Government and Non-governmental policies to be geared towards supporting women with breast cancer to overcome these challenges.

It is known that cervical cancer cells express IL-2 receptor (IL-2R) and those high doses induce cell death. To identify the type of cell death two cervical cancer cell lines, CALO and INBL, were cultured with 100 IU/ml of IL-2. Our results showed the presence of apoptotic cell death by the significant expression of phosphatidylserine on the external surface of cellular membranes, the presence of a typical DNA fragmentation and the activation of caspase 3. We also observed that the expression of COX I, COX II and COX III was not significantly altered while that of COX IV was completely inhibited. An increased expression of cytochrome-C by confocal microscopy was observed. Finally, we speculate that the clinical effect and toxicities of IL-2 used in cancer therapies is mostly due to its apoptotic effect on the cancer cells themselves rather than, as thought, the cytotoxic contribution of leukocytes.

Background and aim: Mucoepidermoid carcinoma is a common salivary tumor that affects both adults and children. Proliferation is one of the most fundamental biological processes of growth and maintenance of tissue homeostasis. CD-44 may be used as an indicator of aggressive behavior of some human malignancy. Multidrug resistance is one of the major obstacles for successful cancer chemotherapy. The present study was carried out for evaluation of the biological rules and the clinicopathological significance of Ki-67, CD-44 and MDR-1 expression in the different histopathological grades of MECs.Patients and methods: Eighty paraffin embedded MEC tissues were collected and classified to three groups according to their histological grades. Tissue sections were stained with Ki-67, CD-44 and MDR-1 then examined microscopically and analyzedstatistically.Result: High grade MEC cases showed the highest expression for Ki-67, CD-44 and MDR-1. Additionally, significant differences were found between the histopathological grades as well as between lymph node stages of the studied cases and the expression of the three utilized markers.Conclusion: Ki-67, CD-44 and MDR-1can be used to evaluate the degree of differentiation and to predict the prognosis of MECs, furthermore, high grade MEC cases with high proliferative indices might be resistant to chemotherapy.

Background: Obstructive jaundice is a common problem in the medical and surgical gastroenterological practice. Malignant obstructive jaundice can be caused by cancer head of pancreas, periampullary carcinoma, carcinoma of the gall bladder and cholangiocarcinomas.Objective: To review the etiological spectrum of malignant obstructive jaundice in NCI Cairo university during a period of 3 years (2008 till 2010).Patients and methods: Retrospective study including 232 patients who presented with malignant obstructive jaundice between (2008 to 2010). Data were collected from the biostatistics and cancer epidemiology department.Results: Out of 232 patients; 156 (67.2%) were male and 76 (32.8%) were female; the median age of the study population was 49 years (range 19-80 years). Our results indicate that the expression of CXCR4 and mTOR may be poor prognostic biomarkers in DLBCL. The commonest cause of malignant obstructive jaundice was pancreatic head cancer, 72% (167/232), followed by the ampullary carcinoma 15% (36/232). The last cause was cholangiocarcinoma 12.5% (29/233). Regarding the commonest symptom; clay colored stools (98.7%) was more frequent in patients with malignant disease whereas abdominal pain (97.7%) was2nd common symptom.Conclusion: Obstructive jaundice is more common among males and cancer head of pancreas is the commonest malignancy. US, ERCP and CT-Scan are important diagnostic modalities for evaluation of patient with obstructive jaundice with ERCP having the additional advantage of being therapeutic as well.

Background: Aromatase inhibitors (AIs) represent an effective endocrine treatment for hormone receptor-positive postmenopausal breast cancer patients with early stage or metastatic disease.Objective: Assessment of Cardiotoxicity in Hormone positive Postmenopausal Breast Cancer Patients receiving AIs (upfront orswitch therapy).Methods: This cross sectional study included 123 postmenopausal breast cancer patients presented to the Clinical Oncology Department, Ain Shams University (Cairo, Egypt) in the interval from August 2016 to June 2017 with hormone receptor positive receiving Aromatase Inhibitors, To assess cardiotoxicity in these patients, they were subjected to blood pressure and lipid profile measurement, electrocardiography (ECG), and electrocardiography (ECHO) and classified into patients had Nolvadex then A.I (arm 1) and others had upfront A.I (arm 2).Results: The age of patients ranged from 41 years to 85 years with mean age of 61 years. Seventy one patients (57.7%) showed cardiotoxicity as assessed by ECHO. They showed significant correlation with rising age above 62 years, IHD, history of HTN and DM (p value: .001, .001, .017 and 0.035 respectively). However, correlation between cardiotoxity and blood pressure changes, lipid profile changes and ECG findings and ECHO changes in switch therapy and upfront A.I were not statistically significant (p value = .275, .116, .081 and .761 respectively).Conclusion: Assessment of cardiotoxicity in hormone positive postmenopausal breast cancer patients receiving Aromatase Inhibitors showed evidence of cardiotoxicity in half the patients (57.7%) as detected by ECHO only. They showed statistically non significant correlations either recievied switch therapy or upfront A.I.

Background: Endoscopic ultrasound (EUS) has gradually become the main stream method of the diagnosis and local treatment of pancreatic tumors. Endoscopic ultrasound (EUS) is frequently used in making the cytological diagnosis of pancreatic cancer and its great role in the pre-operative staging of pancreatic tumors.Objective: To evaluate the role of EUS in diagnosis and treatment of pancreatic tumors prospectively for 2 years study 2014-2015.Patients and methods: Prospective study including 70 patients who presented with pancreatic tumors underwent EUS at the endoscopy unit at Faculty of Medicine Cairo University and National Cancer Institute, Cairo University.Results: Out of 70 patients; median age was 55 years (range 32-73 years). Males were 32 (46%) and females were 38 (54%). Jaundice was the main symptom 47 (67%), clay colored stool 46 (65.7%), dark urine 47 (67%) and abdominal pain 50 (71%). There were 20 patients with benign disease and 50 patient with malignant disease. The following results showing the accuracy of the EUS in detecting malignant pancreatic tumors; Sensitivity: 96.0%, specificity: 75%, PPV: 90.6%, NPV: 88.2%, accuracy: 90.0%.Conclusion: EUS can clarify locoregional spread when CT/MR are equivocal. EUS Elastography is a new application in the field of the endosonography and seems to be able to differentiate fibrous and benign tissue from malignant lesions. The combination of superior detection, good staging, tissue diagnosis and potential therapy makes EUS guided FNA a cost-effective modality.
