In this study, the expression of DNA excision repair cross-complementing gene 1 (ERCC1) in local advanced nasopharyngeal carcinoma has been correlated with the efficacy of concurrent chemoradiotherapy. A total of 76 patients diagnosed with undifferentiated nasopharyngeal carcinoma diagnosed by nasopharyngeal biopsy and undergoing single-agent cisplatin chemotherapy (80 mg/m(2)) with concurrent ...
BACKGROUND AND OBJECTIVE In nasopharyngeal cancer, conventional white light endoscopy does not provide adequate information to detect the flat/small lesion and identify the margin of observable tumor. In the present study, we evaluate the potential of light-induced fluorescence spectroscopic imaging for the localization of cancerous nasopharyngeal tissue. STUDY DESIGN/MATERIALS AND METHODS We...
A case-control study of nasopharyngeal carcinoma was conducted in northeast Thailand, a region which shows an intermediate risk for this neoplasm. The study was conducted to investigate the importance of environmental exposures, particularly salted fish consumption, cigarette smoking, alcohol drinking, and occupational exposure to smoke or dust, as risk factors for the disease. Data from 1 20 n...
Sinonasal squamous papilloma is a benign epithelial tumor having variable squamous differentiation. It occurs in the nasal cavity and paranasal sinuses. Malignant transformation of sinonasal squamous papilloma is responsible for cancer-related deaths worldwide. We reported a 52-year old man diagnosed as malignant transformation of a large sinonasal squamous cell papilloma. Moreover, bilateral n...

A 49-year-old man attended our department complaining of progressive difficulty in swallowing over a period of 2 weeks. He reported no other discomfort. His medical history revealed that he had been diagnosed with nasopharyngeal carcinoma (cT3N3bM0; WHO Type III) in September 2008 and had undergone chemotherapy and radiotherapy concurrently. A complete response was achieved initially, but regio...
Introduction: In radiation therapy, accurate dose determination and precise dose delivery to the tumor are directly associated with better treatment outcomes in terms of higher tumor control and lower post radiation therapy complications. The current study aims the development and clinical application of the Patient Specific Quality Assurance (PSQA) procedures for nasopharyngea...
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...
Copper(II) ternary complex, [Cu(phen)(C-dmg)(H2O)]NO3 was evaluated against a panel of cell lines, tested for in vivo efficacy in nasopharyngeal carcinoma xenograft models as well as for toxicity in NOD scid gamma mice. The Cu(II) complex displayed broad spectrum cytotoxicity against multiple cancer types, including lung, colon, central nervous system, melanoma, ovarian, and prostate cancer cel...
Altered expression of long noncoding RNAs (lncRNAs) associated with human carcinogenesis. We performed a cDNA microarray analysis of lncRNA expression in 12 cases of nasopharyngeal carcinoma (NPC) and 4 non-tumor nasopharyngeal epitheliums. One lncRNA, actin filament associated protein 1 antisense RNA1 (AFAP1-AS1), was identified and selected for further study. AFAP1-AS1 expression was upregula...
