Do Fibroblast Growth Factor Receptor (FGFR) 2 and 3 Proteins Play a Role in Prognosis of Invasive Urothelial Bladder Carcinoma?

Background & Objective: Bladder carcinoma ranks second in prevalence among males in Egypt. As a family of tyrosine kinases, fibroblast growth factor receptor (FGFR) dysregulation has been linked to some malignancies in humans. The aim of this study is to analyze the clinicopathological data of patients while investigating FGFR2 and FGFR3 immunohistochemical expression in invasive urothelial bladder carcinoma.

Role of Serine arginine protein kinase 1 and Minichromosome maintenance protein 2 in predicting epithelial ovarian cancer response to treatment and prognosis.

Background: Serine-Arginine (SR) proteins are a conserved family of proteins involved in RNA splicing and are reported to be over-expressed in multiple cancers. The aim of the study is evaluation of the expression of Serine arginine protein kinase 1 (SRPK1) and Minichromosome maintenance protein 2 (MCM2) in epithelial ovarian cancer (EOC) and their correlation with clinicopathological features, response to therapy, progression-free survival (PFS), and cancer-specific survival (CSS).

Methods: This study was carried out on surgical specimens of 65 patients diagnosed with EOC which were submitted to immunohistochemical staining by SRPK1 and MCM2 antibodies.

Mutation-Agnostic Detection of Colorectal Cancer Using Liquid Biopsy-Based Methylation-Specific Signatures.

Detection of methylation patterns in circulating tumor DNA (ctDNA) can offer a novel approach for cancer diagnostics given the unique signature for each tumor type. We developed a next-generation sequencing (NGS)-based assay targeting 32 CpG sites to detect colorectal cancer-specific ctDNA. NGS was performed on bisulfite-converted libraries and status dichotomization was done using median methylation ratios at all targets.

Prognostic significance of LRIG2 and LRIG3 proteins in urothelial bladder carcinoma.

Bladder carcinoma is the second most frequent cancer in Egyptian males. Leucine-rich and immunoglobulin-like domains (LRIGs) are usually dysregulated in various human tumors. The aim of this study is to explore the immunohistochemical expression of LRIG2 and LRIG3 in urothelial bladder carcinoma (UBC) and their relationship to patients clinicopathological data including survival.

Stratification of urothelial bladder carcinoma depending on immunohistochemical expression of GATA3 and CK5/6.

Bladder urothelial carcinoma (BUC) has two pathways with distinct molecular features and prognosis, non-muscle invasive (NMI) and muscle invasive (MI) tumors. The aim is to investigate the expression of GATA3 and CK5/6 in BUC with correlation to clinicopathologic parameters, including their impact on survival beside their potential use to stratify cases into prognostic subgroups. This study included 80 cases of BUC stained immunohistochemically by GATA3 and CK5/6.

Circulating miR-21-5p and miR-126-3p: diagnostic, prognostic value, and multivariate analysis in non-small-cell lung cancer.

One of the most recent of tumor molecular characterization approaches is the microRNA (miR) expression profile. No single marker is sufficiently accurate for clinical use. Numerous biomarkers panels were created for three main purposes: tumor subtype, classification and, early detection, and prediction of tumor responses to treatment and prognosis of patients.

Clinical Significance of Immunohistochemical Expression of Neuropeptide Y1 Receptor in Patients With Breast Cancer in Egypt.

Breast cancer (BC) is the most common malignancy in female individuals worldwide. It constitutes about 38.8% of all malignant tumors among Egyptian female individuals.

Biochemical study on modifying role of variants of leptin gene and its receptor on serum leptin levels in breast cancer.

The leptin is discharged from breast adipose tissue and is overexpressed in breast cancer (BC). Conflicting relation of leptin with BC was reported. We investigated this association and its impact on leptin level and disease characteristics.

The Role of Diuretics in Treatment of Aromatase Inhibitors Induced Musculoskeletal Symptoms in Women with Non Metastatic Breast Cancer.

Background: Around 50% of women receiving Aromatase Inhibitors (AIs) develop musculoskeletal symptoms which may become severe causing interruption of treatment. Patients with AI-induced arthralgia had higher rates of joint effusions and fluid in the tendons, so use of diuretics may be helpful. Methods: This prospective phase II study was conducted in department of clinical oncology and nuclear medicine, Menoufia University Hospital, Egypt, between Jan.

Serum circulating cell free DNA as potential diagnostic and prognostic biomarker in non small cell lung cancer.

Background: Non-small cell lung cancer (NSCLC) is leading cause of cancer related death and the survival rate for patients with NSCLC remain poor so early diagnosis of NSCLC represents the best opportunity for cure. Cell-free DNA (cf-DNA) is extracellular nucleic acids found in cell-free plasma/serum of humans, given the recent approval of a liquid biopsy in lung cancer, the use of circulating tumor DNA as a novel non-invasive diagnostic and prognostic biomarker is promising.

Objectives: Studying whether the concentrations of circulating Cell Free DNA in serum can be used as a diagnostic and prognostic biomarker for NSCLC patients.

Prognostic Factors for Hormone Sensitive Metastatic Prostate Cancer: Impact of Disease Volume.

Background and Aim: The optimal management of metastatic hormone-sensitive prostate cancer has been controversial in recent years with introduction of upfront chemohormonal treatment based on results of several Western studies. This changing landscape has renewed interest in the concept “disease volume”, the focus of the present study is the Egyptian patients. Methods: Patients with hormone sensitive metastatic prostate cancer presenting at Menoufia University Hospital, Egypt, during the period from June 2013 to May 2016, were enrolled.

Leptin receptor gene (A/G) polymorphism rs1137101 and renal cell carcinoma.

Leptin plays an important role in carcinogenesis as leptin/leptin receptor signaling promotes the angiogenesis, proliferation, and inhibits epithelial cell apoptosis. Variants in the leptin receptor gene have potential associations with renal cell carcinoma (RCC). We aimed to investigate association of rs1137101 (A/G) polymorphism at LEPR gene with risk of RCC and patients survival.

Metastatic Collision Tumour (Papillary Thyroid Carcinoma and Squamous Cell Carcinoma) in Cervical Lymph Nodes: An Immunohistochemical Analysis.

Collision tumours are a rare entity, in this report, we describe a case of 73-year-old woman presented with a rapid enlargement of left upper cervical lymph node (LN) associated with right thyroid nodular goiter. The histopathological examination of the excised LN showed definite areas of papillary thyroid carcinoma admixed with moderately differentiated squamous cell carcinoma (SCC). Thyroglobulin immunostaining was positive in papillary carcinomatous areas confirming thyroid gland as a source of metastasis.

Primary Epithelioid Angiosarcoma of Spleen: A Case Report and Review of Literature.

Splenic angiosarcomas are usually secondary tumours, and only few primary cases have been encountered. We report a unique primary case of epithelioid angiosarcoma arising in the spleen in a male patient 55-year-old and presented to our hospital as a medical emergency with acute abdomen and haemorrhagic ascitis. CT revealed splenic focal lesion and suggested that this abdominal haemorrhage was due to ruptured splenic haemangioma, thus abdominal exploration and splenectomy were done.
