BACKGROUND Epstein-Barr virus (EBV) is considered to be closely associated with nasopharyngeal carcinoma (NPC), in which EBV-encoded latent membrane protein 1 (LMP1) was found to have an oncogenic role. However, the results published on the LMP1 polymorphism are inconsistent. In the present study, we performed a meta-analysis to determine the frequency of the associations and a more precise ass...

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...

BACKGROUND Various studies have assessed the prognostic value of epidermal growth factor receptor (EGFR) overexpression in nasopharyngeal carcinoma (NPC), but their results remain controversial. METHODS Studies published up to January 2013 were collected. A total of 16 studies involving 1179 patients were reviewed. A meta-analysis was performed to clarify the prognostic role of EGFR in patien...

BACKGROUND Sinus mucosa abnormalities on image studies, which is the major diagnostic measure for sinusitis, were investigated in patients with nasopharyngeal carcinoma (NPC) after intensity-modulated radiotherapy (IMRT). METHODS A retrospective review of the MRIs for patients with NPC was conducted. Sinus mucosa abnormalities were staged by the Lund-Mackay system. RESULTS A total of 94 pat...

This retrospective study aims to examine the association of plasma Epstein-Barr virus- (EBV-) DNA levels with the tumor volume and prognosis in patients with locally advanced nasopharyngeal carcinoma (NPC). A total of 165 patients with newly diagnosed locally advanced NPC were identified from September 2011 to July 2012. EBV-DNA was detected using fluorescence quantitative polymerase chain reac...

Adult hippocampal neurogenesis drastically diminishes with age but the underlying mechanisms remain unclear. Here, age-related influences on the hippocampal early neuroprogenitor cell (NPC) pool was examined by quantifying changes in Sox1-expressing cells in the dentate gyrus subgranular zone from early adulthood (3 months) to middle age (12 months). Proliferation of distinct NPC subpopulations...

BACKGROUND To evaluate the efficacy and toxicity of docetaxel, cisplatin, fluorouracil (TPF) regimen followed by intensity modulated radiotherapy (IMRT) on locally advanced nasopharyngeal carcinoma (NPC). METHODS A total 150 patients with NPC [American Joint Committee Cancer (AJCC) 2009 stage IIIa-IVb] received 2 or 3 cycles a TPF as induction chemotherapy. group 67 participants (TPF group) con...

Although Epstein-Barr virus-associated nasopharyngeal carcinoma (NPC) is a highly radiosensitive cancer, approximately 20% of patients with NPC develop local recurrence after radiation therapy. Multiple proinflammatory cytokines are thought to protect NPC tumor cells from immune surveillance and therapeutic interventions. The cytokine leukemia inhibitory factor (LIF) is a critical component of ...
