background : nasopharyngeal carcinoma (npc) is known as a highly distinct kind of head and neck cancer. this distinction is due to its clinical presentation, epidemiology, outcome, and treatment. there have not been any reports of epidemiological analysis of npc in iran. the aim of this study is to evaluate the incidence rates and trends of nasopharyngeal carcinoma in the iranian population dur...
Introduction: Nasopharyngeal carcinoma (NPC) is a rare malignancy in children. Nasal obstruction, otitis media with effusion, pain in the ear, hearing problems, and unusual neck mass are among the signs and symptoms of this malignancy. Case Report: We report the case of a 13-year-old girl with NPC who later developed acute lymphoblastic leukemia (ALL) through the course of her disease. To our...
abstract background: nasopharyngeal carcinoma (npc) is a nonlymphomatous squamous cell carcinoma (scc) that occurs in the epithelial lining of the nasopharynx. viral, geographic, and ethnic factors are responsible for its multifactorial futures. previous studies have showed the role of epstein-barr virus (ebv) in the pathogenesis of npc but no study has been conducted on the iranian populatio...
Background: Local recurrence in Nasopharyngeal Carcinoma (NPC) presents is a major challenge. Patients experience substantial morbidity as well as poor survival if no further treatment is offered. Residual or recurrent nasopharyngeal carcinoma is usually managed by chemotherapy, stereotactic radiosurgery, external beam radiation therapy (EBRT), interstitial, and intracavitary brachytherapy or s...
Nasopharyngeal carcinoma, particulary tumors endemic to the Far East, commonly harbors Epstein-Barr virus. The detection of nuclear antigen associated with EBV and viral DNA in NPC cells have revealed that EBV can infect epithelial cells and is associated with transformation. Human papilloma virus is an epitheliotrophic oncogenic virus that has been detected in a variety of head and neck tu...
Recent development of cutting edge research found that long noncoding RNAs (lncRNAs) plays important roles in carcinogenesis and progression. In Southeast Asia and North Africa, nasopharyngeal carcinoma (NPC) is the most common aggressive squamous cell carcinoma. Nasopharyngeal carcinoma is most frequently occurring in males. However, nasopharyngeal carcinoma is caused by a combination of sever...
Background and purpose: The association of nasopharyngeal carcinoma (NPC) and Epstein-Barr virus (EBV) was firmly established as early as 1973. A clear understanding of its etiology is still lacking, but nasopharyngeal carcinoma is widely suspected to be the result of both a genetic susceptibility and exposure to environmental factors or Epstein-Barr virus infection. NPC is more prevalent in yo...
OBJECTIVE To investigate the expression profile and the clinical significance of CDK3 in the tissues of nasopharyngeal carcinoma. METHOD Immunohistochemistry was utilized to detect the expression of CDK3 in 94 cases of NPC and 40 cases of nasopharyngeal inflammation. RESULT CDK3 was highly expressed in NPC cell lines. Immunohistochemistry showed that CDK3 was mostly expressed in the cytopla...
Background: The role of locoregional radiotherapy (LRT) the nasopharynx and neck in patients with metastatic nasopharyngeal carcinoma (M-NPC) remains unclear. present meta-analysis aimed to compare efficacy chemotherapy (CT) plus LRT CT alone M-NPC patients.
