Background and Objective: BRAF mutations were studied in various populations for prostate carcinoma (PC); however, mutations in BRAF gene are unusual compared to KRAS. Oncogenic activating of BRAF mutations were studied lately in almost 0%-10% of prostate cancer cases. Methods: In this retrospective study, we gathered 100 formalin-fixed ...
aim : we aimed to explore the frequency of braf v600e mutation in iranian patients with colorectal cancer (crc) as well as its association with clinic pathological characteristic of patients. background : crc is the third leading cause of cancer related death. there is a growing body of data showing the association of braf v600e mutation with malignant transformation and clinical outcome of d...
Background & Objective: This study was designed for the first time for the detection of mutant BRAF V600E and its correlation with clinicophathologic features in a sample of Iranian patients with pathologically proved pigmented skin neoplasms.Methods: 82 paraffin-embedded blocks, including melanocytic nevi, malignant melanoma, Basel cell carcinoma, and sq...
چکیده: تومورهای غددبزاقی حدود 5-3 % از سرطانهای سر و گردن را شامل می شوند و جزء مهمترین ضایعات این ناحیه محسوب میشوند. موکو اپی درموئید کارسینوما ،آدنوئید سیستیک کارسینوما و آدنو کارسینوما پلی مورفوس با درجه پایین شایع ترین تومورهای بدخیم غدد بزاقی در نظر گرفته می شوند. پیش آگهی و میزان بقاء بیماربه عوامل مختلفی بستگی دارد.stage یا مرحله بالینی یک پارامترکمی و بهترین شاخص جهت تعیین پیش آگهی بی...
Background: Head and neck squamous cell carcinoma (HNSCC) is the malignancy of squamous cells (the epidermal layer of skin) in cavities in head and neck includes: larynx, pharynx, paranasal sinuses and oral cavity. The main goal of this research was to understand the effect of mutations in two important genes (KRAS and BRAF) in RAS/MAP kinase (EGFR) signaling pathway in tumor cells with head an...
Abstract Background & Aims:BRAF-V600E mutation has recently been considered as a molecular marker in diagnosis of Hairy Cell Leukemia (HCL). Detection of this mutation has found a diagnostic and therapeutic value. The aim of the present study was comparing the diagnostic value of BRAF V600E mutation detection with other previous methods in diagnosis of HCL patients. Materials & M...
knowledge about the clinical significance of v-raf murine sarcoma viral oncogene homolog b1 ( braf ) mutations in colorectal cancer (crc) is growing. braf encodes a protein kinase involved with intracellular signaling and cell division. the gene product is a downstream effector of kirsten ras 1( kras ) within the ras/raf/mapk cellular signaling pathway. evidence suggests that braf mutations, li...
Background: Colorectal cancer is one of the most common types of cancer and the cause of death of a large number of patients and requires investigating the causes of the disease and adopting targeted therapies. Considering the diagnostic, therapeutic, and prognostic significance of genetic markers, in the present study BRAF-V600E gene mutation was evaluated in tissue samples of colorectal cance...
Introduction: Malignant salivary gland tumors are rare entities. Despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. The activation of EGFR- RAS-RAF signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic m...
