Background Nasopharyngeal carcinoma (NPC) is especially prevalent in southeast Asia and southern China, but its molecular mechanisms remain poorly characterized. DNA methylation is associated with initiation and progression of tumors, including NPC. Through a genome-wide DNA methylation screening approach, we discovered ZNF154, but its methylation status and roles in NPC have not been investiga...

Nasopharyngeal cancer (NPC) is a unique disease with increasing interest for many physicians due to its unusual etiology, histology, and epidemiology. The recent era of fiberoptic endoscopy now provides the clinician with better tools for the screening, diagnosis, staging, and follow-up of NPC. The use of high resolution flexible and rigid nasopharyngoscopy gives the physician an opportunity fo...

BACKGROUND Treatment protocols for nasopharyngeal carcinoma (NPC) developed in the past decade have significantly improved patient survival. In most NPC patients, however, the disease is diagnosed at late stages, and for some patients treatment response is less than optimal. This investigation has two aims: to identify a blood-based gene-expression signature that differentiates NPC from other m...

Nasopharyngeal carcinoma (NPC) of the undifferentiated subtype remains endemic in southern China, with a peak incidence in this region approaching 30 cases per 100,000 population per year. Despite advances in chemotherapy and radiation delivery techniques in localized disease, distant metastasis is still common and NPC remains the seventh leading cause of cancer death in the region. There is gr...

Niemann-Pick disease, type C is a neurodegenerative, lysosomal storage disorder with a broad clinical spectrum and a variable age of onset. The absence of a universally accepted clinical outcome measure is an impediment to the design of a therapeutic trial for NPC. Thus, we developed a clinical severity scale to characterize and quantify disease progression. Clinical signs and symptoms in nine ...

Conventional treatment for nasopharyngeal carcinoma (NPC) frequently fails and is accompanied by severe long-term side effects. Since virtually all undifferentiated NPCs are associated with Epstein-Barr virus (EBV), this tumor is an attractive candidate for cellular immunotherapy targeted against tumor-associated viral antigens. We now demonstrate that EBV-specific cytotoxic T-cell (CTL) lines ...

Rare disease represents one of the most significant issues facing the medical community and health care providers worldwide, yet the majority of these disorders never emerge from their obscurity, drawing little attention from the medical community or the pharmaceutical industry. The challenge therefore is how best to mobilize rare disease stakeholders to enhance basic, translational and clinica...

Nasopharyngeal carcinoma (NPC) with distant metastases has poor prognosis. Metastatic sites are usually multifocal and involve bones, lungs and live. Management of metastatic disease is essentially palliative and is based on chemoradiotherapy. A 48-year-old man with a solitary liver metastasis from a newly diagnosed NPC was treated by segmentectomy. Prior to radiotherapy, neoadjuvant chemothera...
