MMed, Otorhinolaryngology, Faculty of Health Sciences, University of the Witwatersrand / This study is a six year retrospective review of the histopathology of nasopharyngeal masses in adult patients who underwent a biopsy in theatre at the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) from 1st January 2003 to 31st December 2008. Eighty one patients were included in this study. They comprised of 54 males (67%) and 27 females (33%) aged between 18 and 82 years. There was no statistical difference between the two genders in terms of their ages (p= 0.39). Fifty two patients (64%) had benign disease and 29 patients (36%) had malignant disease (ratio 1.8:1). Thirty four males (65%) and 18 females (35%) had benign disease. Twenty males and 9 females had malignant disease. There was no significant correlation between gender and malignancy (r= -0.04, p=0.75). The independent predictors of the nature of the tumour were: nasal congestion, epistaxis, hearing loss, otalgia and Human Immunodeficiency Virus (HIV) status. The statistically significant positive predictors of malignancy were the presence of nasal congestion, epistaxis and otalgia. The presence of at least one or more of these symptoms was associated with an odds ratio of 3.06 for malignant disease. (CI= 1.17-8.01). The presence of hearing loss was independently associated with benign disease (p=0.031). The HIV status was known in 41 of the 81 patients. Of the 41 patients whose HIV status was known, 25 were male and 16 were female. The HIV positive patients comprised of 19 males (76% of all males) and 9 females (56% of all females). The presence of HIV infection was independently associated with benign disease. The absence of HIV infection was in fact associated with malignant disease, with an odds ratio of 4.00 and 95% confidence intervals of 1.04 to 15.43.

²Ä¤@³¡¥÷ Nasopharyngeal carcinoma¡]NPC¡^ is a malignant tumor which occurs at high incidence in southern China. Several risk factors have now been recognized, but the molecular mechanism of this disease is not well understood. To investigate the c-myc¡Bcyclin D1¡Bp16¡Bp27 and Rb gene expression in NPC at protein level, 46 cases of nasopharyngeal carcinoma in southern Taiwan were detected by immunohistochemistry. There was no detectable p16 in 31/45 cases¡]69¢M¡^¡F 34/46 cases¡]73.9¢M¡^had intense staining for the Rb protein¡F 29¡]70.7¢M¡^of 41 cases had c-myc protein expression¡Fcyclin D1 was not overexpression in nasopharyngeal carcinoma¡F 32¡]69.6¢M¡^of 46 cases had high level expression of p27, which was inverse correlation with other tumors. No expression of c-myc protein correlated with higher neck metastasis¡]P¡Õ0.05¡^. No correlation was found between other proteins and any of the clinicopathological parameters. ²Ä¤G³¡¥÷ To better understand nasopharyngeal carcinoma¡]NPC¡^, we have newly established two NPC cell lines. Biopsy specimens from NPC patients were collected, primary culture were set up. Two NPC cell lines were established¡GNPCGK 01 was derived from differentiated carcinoma and NPCGK 02 was derived from undifferentiated carcinoma. Two cell lines have been passaged for more than 25 times. Two cell lines had telomerase activity¡Fstrong expression of hTERT gene and keratin-19 gene were also observed. TGF£] RI protein expression of these NPC cell lines is higher than normal epithelial cell.The oncogenes, c-myc¡Bc-fos and cyclin D1 were overexpressed. The Rb protein was expressed stronger than normal epithelial cells. NPCGK 01 that was derived from differentiated carcinoma had p16 down-regulation and p27 gene not expression, but p21 protein had excess expression. In short, two cell lines had cancer cell characteristics, oncoproteins were overexpression and tumor suppressor proteins were abnormal expression. This result may lead to tumorigenesis of nasopharyngeal carcinoma.

Epstein-Barr virus, or EBV, is a human herpesvirus that is nearly universally present in most of the human population. The infection rate in adults is quickly approaching an astonishing 95% worldwide. While the most common clinical manifestation of EBV infection is infectious mononucleosis, there are multiple malignancies strongly associated with the virus, such as nasopharyngeal carcinoma (NPC). A contemporary problem in public health is the scarcity of markers to predict the development of EBV-associated malignancies, which prevents a possible cure or a suitable treatment. Of the approximately 85 proteins that the virus expresses, EBV serological tests rely on detection of antibodies against only three antigens: BFRF3 (viral capsid antigen or VCA), BMRF1 (early antigen or EA), and BKRF1 (nuclear antigen or NA). Antibodies against two of these antigens, VCA and NA, are produced by almost all EBV carriers for their entire lifetime, and so detection of these antibodies can make it difficult to differentiate between non-cancerous EBV carriers and EBV-associated cancer patients. To address this problem, the project aimed to identify a set of markers to diagnose NPC and treat it. To test this, 3 EBV genes were cloned with a 3X FLAG-tag into a mammalian expression vector, then expressed and detected by immunoblotting with a monoclonal FLAG antibody and each of the 9 human serum samples used in this study. Our results were generally inconclusive, and further studies are warranted to explore possible diagnostic and prognostic biomarkers.
