Background: Tumor lysis syndrome caused by widespread tumor cell damage may lead to electrolyte imbalances and express as metabolic disturbance causing clinical abnormalities. Patients and Methods: All patients younger than 16 years with documented malignancy candidate for chemotherapy, in Hamedan province of Iran were enrolled. Results: Out of 69 cancer patients the laboratory form of tumor ...

cancer stem cells (cscs) are unique subpopulations that have the capacity to drive malignant progression with renewal abilities. recently the role of some of cscs in gastric adenocarcinoma has been studied. this study was performed in order to evaluate cd44 and cd133 expressions by immunohistochemistry in 95 primary gastric adenocarcinoma and their relation to clinical and pathological paramete...

Background and Aims: An impairment of expression in MLL2 gene involved in histone methylation induces alteration in the methylation patterns at enhancers and causes several cancers including colon cancer. In this study, MLL2 expression was evaluated in North West of Iran. Materials and Methods: To evaluate the MLL2 expression in patients with colon cancer, 25 tumor samples and 25 samples of tu...

objective: to review her-2/neu and tp53 status and their correlation with all other prognostic clinicopathologic features of infiltrative ductal breast carcinomas. materials and methods: this cross sectional study was performed on 139 patients with infiltrative ductal breast carcinoma who were diagnosed between may 2000 and march 2006 at the surgery and pathology departments of alzahra hospital...

background: determination of the impact of angiogenesis on tumor development and progression is essential. this study aimed to determine the serum levels of vascular endothelial growth factor (vegf) and interleukin 6 (il-6) in breast carcinoma, and to correlate them with tumor size, lymph node involvement, and cancer stage. methods: under aseptic precautions 5 ml of venous blood was collected f...

The incidence of thyroid and the prevalence of follicular carcinoma is rare in childhood and adolescents; however, it is considered as the second most common pediatric thyroid malignancy. Vascular invasion, distant metastasis, and tumor size greater than 4 cm are among the factors leading to total thyroidectomy followed by radioactive iodine therapy. The tumor size of the case in this study was...
