Abstract
BACKGROUND The management of liver metastases from nasopharyngeal carcinoma (NPC) has not been extensively investigated. This study aimed to compare the long-term outcome of patients with liver metastases from NPC who were treated by a partial hepatectomy or transcatheter hepatic artery chemoembolization (TACE). METHODS Between January 1993 and December 2010, 830 patients were diagnosed with liver metastases from NPC and exhibited a complete response to the primary cancer of the nasopharynx and regional lymph nodes. Fifteen patients with intrahepatic metastasis underwent R0 partial hepatectomy. As a parallel control group, another 15 patients with a resectable liver metastasis who underwent TACE were selected. Prior to the resection and TACE that were performed on patients in these two groups, radical radiotherapy with or without adjuvant chemotherapy was administered. Clinicopathological data and treatment outcomes were compared retrospectively. RESULTS No significant differences were observed between the two groups in terms of the clinicopathological features, which include gender ratio, liver function, accompanying cirrhosis, rate of infection with the hepatitis B virus, tumor size, tumor number, pathological type and preoperative comorbidities. The 1-, 3- and 5-year overall survival rates from the time of hepatectomy were 85.7%, 64.2% and 40.2%, respectively, with a median survival of 45.2 months, whereas the 1-, 3- and 5-year overall survival rates were 53.3%, 26.6% and 20.0% for patients in the control group (P = 0.039), respectively, with a median survival of 14.1 months. The actuarial median progression-free survival (PFS) of the patients in the resection group was 21.2 months, and the 1-, 3- and 5-year PFS rates were 70%, 53% and 18%, respectively. In the control group, the 1-, 3- and 5-year PFS rates were 27%, 7% and 0.0% (P = 0.007), respectively, with a median survival of 4.2 months. Thus far, 5 patients have survived for more than 5 years, and the longest survival time is 168.1 months. CONCLUSIONS For patients with limited liver metastases from NPC, hepatectomy provides a survival advantage over TACE. Due to the limited treatment options for patients with liver metastasis from NPC, hepatectomy should be recommended as an optimal treatment. Moreover, perioperative chemotherapy may be associated with an improved prognosis.

Abstract
PURPOSE To compare therapeutic results of nasopharyngeal carcinoma between adults and children. PATIENTS AND METHODS Three hundred and seventy seven patients with nasopharyngeal carcinoma received a radiotherapy between 1993 and 2007. Sixty-nine of them were 20years old or less. Two hundred and sixty eight patients received a chemotherapy (neoadjuvant or concomitant). RESULTS Overall survival and disease-free survival at 5 years were 67 % and 59.4 % in all patients, respectively. Overall survival rates at 5 years in children and adults were 66 % and 64 %, respectively (P=0.17), disease-free survival rates at 5 years were 66 % and 57 %, respectively (P=0.17). Local failures occurred more frequently in adults than in children (1.4 % versus 14 %). However, metastatic events were frequently seen in children. Late toxicities were important in children, xerostomia was the most common one. CONCLUSION Despite locally advanced disease in children, therapeutic results were better than in adults but not statistically significant. The use of treatment combination (chemotherapy and radiotherapy) in juvenile nasopharyngeal carcinoma may explain our findings.

Abstract
BACKGROUND Nasopharyngeal carcinoma (NPC) is a malignant epithelial tumor intimately associated with Epstein-Barr virus (EBV). NPC is a characteristic tumor displaying epidemiological, genetic and regional distribution properties that makes it unique by its natural behavior. OBJECTIVES To assess the expression pattern of LMP1 and p53 proteins in the different histological types of NPC in a sample of the Moroccan population and to define any association between the expression of those proteins with the sex, the age and the histological types of NPC. METHODS Archival formalin-fixed, paraffin-embedded NPC biopsies were evaluated in 23 Moroccan patients for the presence of LMP1 and p53 using immunohistochemistry (IHC). RESULTS No LMP1 expression was observed whereas 8 of 23 cases (34. 7%) had detectable p53 protein in the nuclei of tumor cells. After statistical analysis according to the Fisher's exact probability test, no significant association between p53 expression and histological type, age and sex distributions was demonstrated (p>0.05). CONCLUSION This study confirms that p53 overexpression is present in a subset of Moroccan NPC patients. Our results are consistent with those reported by other studies concerning the same NPC endemic risk area and provide original data concerning Morocco.

Abstract
CONCLUSION Changes in tumor necrosis factor-alpha (TNF-alpha) and soluble interleukin-2 (sIL-2R) levels appear to be closely related to tumor progression and prognosis in nasopharyngeal carcinoma (NPC). Further investigation is suggested. OBJECTIVES The study examined whether changes in TNF-alpha and sIL-2R in NPC can be used to predict tumor progression and prognosis. PATIENTS AND METHODS The study was carried out in 58 patients with NPC newly diagnosed from December 2003 to December 2006 at a single institution and 60 control subjects of comparable age. Blood levels of TNF-alpha and sIL-2R were monitored before, during, and 3 months and 1 year after treatment. RESULTS Differences in TNF-alpha level between patients with NPC in all four stages and healthy controls and in sIL-2R level between patients with advanced stage NPC and healthy controls were significant (p <0.05). Furthermore, 1 year after completing radiotherapy, levels of TNF-alpha and sIL-2R in patients with recurrent tumors were significantly different from those in patients without recurrence and healthy control subjects.

Abstract
Cancers of the upper aerodigestive tract cover the solid tumors of the oral cavity, pharynx and larynx. The principal risk factors identified are smoking and alcohol. Moreover, the combination of alcohol and smoking increases the relative risk by more than simple multiplication. The pretreatment work-up represents the starting point in the natural history of the patient's disease and conditions recovery and time course; it must be both specific and exhaustive. It leads to a TNM classification or staging that is a major prognostic factor and essential to determination of the appropriate therapy. Patients with cancer of the upper aerodigestive tract must receive cooperative multidisciplinary treatment. Conservative treatment strategies must be favored. Treatment is essentially surgical and radiological. Prognosis for survival is poor. For all stages and sites together, 5-year survival remains between 30 and 40%.

Abstract
PURPOSE To determine the level and prognostic significance of c-kit expression in the two age groups of North African nasopharyngeal carcinomas. PATIENTS AND METHODS A retrospective study of 99 NPC specimens from Tunisian patients was investigated by immunohistochemistry. Immunohistochemical data were correlated with Epstein-Barr virus LMP1 expression and pathological, clinical and survival parameters. RESULTS c-kit was detected in 79% of the cases for patients under 30 years of age (juvenile form) but in only 56% of specimens in patients over 30 years (P=0.039) and was significantly over-expressed for patients with lymph node involvement (P=0.015). LMP1 score was 5.78 (+/-1.84) for c-kit negative tumors compared to 8,23 (+/-2.39) for c-kit positive tumors (P=0.002). Multivariate analysis including age, lymph nodes involvement and LMP1 expression as co-variables, showed that only age (P=0.027) and LMP1 expression (P=0.005) were significantly correlated to the c-kit expression. CONCLUSION c-kit is highly expressed in the juvenile form of North African nasopharyngeal carcinomas. There is a significant association between LMP1 and c-kit expression. The contrasted levels of C-kit expression in the two age groups strengthen the hypothesis that these clinical forms result from distinct oncogenic mechanisms.

Abstract
PURPOSE To study the clinical, radiological, therapeutic and progressive aspects of brain radionecrosis after treatment for nasopharyngeal carcinoma. PATIENTS AND METHODS Nine patients (seven men and two women) of mean age 47.7 years old (extremes: 18-57 years old) were treated for UCNT (undifferentiated carcinoma of the nasopharynx) between 1989 and 2003 and developed cerebral radionecrosis. All patients were treated with radical radiotherapy. The mean total dose was 73.5 Gy (70-75 Gy). Dose per fraction was 2 to 2.5 Gy, one fraction daily. One patient received adjuvant brachytherapy to the dose of 8 Gy and four patients also received chemotherapy. RESULTS Brain radionecrosis was authenticated by brain imaging (CT scan+/-MRI): the imaging was ordered in seven cases to elucidate non-specific neurological signs and two cases were discovered fortuitously. The time to the appearance of neurological signs was 40.3 months (10 to 108 months). The localization was temporal in six cases, parieto-occipital (one case) and bulbomedullar (two cases). After a mean follow-up period of 30.6 months (12-84 months), clinical outcomes were favorable in all cases receiving medical treatment (corticoids), with a stabilization of the radiological lesions in eight cases and complete radiological regression in one patient. CONCLUSION Brain radionecrosis is a late complication rarely occurring in patients irradiated for UCNT. Imaging techniques (CT scan but more so MRI) play a major role in the diagnosis. Corticotherapy resulted in a durable objective response in all patients and, in most cases, resulted in radiological stabilization.

Abstract
BACKGROUND The current retrospective study aimed to identify some determinants of survival in metastatic NPC. METHODS The study concerned 95 patients with metastatic nasopharyngeal carcinoma treated between 1993 and 2001. Statistical comparison between patients subgroups survival was carried out employing the log-Rank test (statistical significance was defined as p<or=0.05). Multivariable analysis was performed using the Cox model (p<or=0.05 was used as the cut-off value of statistical significance). Factors that were considered included: age group(<or=45 years or>45 years and<or=25 years or>25 years), gender, performance status at diagnosis of metastatic disease (PS 0-1 or 2-3), time of metastasis diagnosis(at presentation or later), number of metastatic sites (single or multiple), specific metastatic sites(bone, liver, lung, distant nodes), number of bone metastasis (single or multiple), disease free survival (DFI) (<or= or >6 months), prior chemotherapy, radiotherapy of metastatic sites. RESULTS Negative prognostic factors in univariate analysis were: poor PS (>or=1), multiple metastatic sites, multiple bone metastasis, previous chemotherapy, visceral or node metastasis and non irradiated metastasis. Poor PS, multiple metastatic sites, and prior chemotherapy were independently significant negative prognostic factors in multivariable analysis. CONCLUSIONS In this study we identified new prognostic factors in univariate and multivariate analysis. A regular and careful follow-up of patients treated for NPC is then recommended in order to detect early metastatic dissemination (with minimal localizations) while patients have still a good PS.

Abstract
A rare case report of HIV-associated nasopharyngeal carcinoma concurrent with local polymorphic B-cell lymphoproliferative disorder is reported and discussed on the ground of the most recent literature evidences. Only very few reports of nasopharyngeal carcinoma have been described until now in patients infected with HIV (one case in adults), and a coexisting lymphoid cell proliferation with a concurrent role of Epstein-Barr virus in prompting both disorders was never reported to date. The relevant pathogenetic, diagnostic, and therapeutic questions raised by this infrequent intriguing association retrieved in a patient with prominent HIV-related immunodeficiency are focused on.

Abstract
PURPOSE Nasopharyngeal cancer is the commonest head and neck cancer in Tunisia treated with radiotherapy. A dose effect relationship is established in this tumor. The aim of this study is to describe our Low-dose-rate endocavitary brachytherapy using a personalized mold called Tunis applicator. PATIENTS AND METHODS Seven patients (4 males and 3 females) with histologically confirmed undifferentiated nasopharyngeal carcinoma (UCNT) were treated between 2002 and 2005. Five patients with primary cancer and 2 with recurrent disease received external beam radiation followed by endocavitary brachytherapy. The mean applied dose of endocavitary brachytherapy was 5.5 Gy for primary site after external beam radiation (70-74 Gy) and 30 Gy for recurrent disease after external beam radiation (38 Gy). We have developed a personalized applicator with a balloon to optimize the placement of sources and a better conformity using the computer tomography scanning. Critical normal structures were identified on orthogonal radiographs and the dose was optimized to avoid excessive doses to these structures. RESULTS With a follow up of 18 months (8-41), only one local failure was observed, 3 years after external beam radiation therapy for a recurrent disease. Moderate grade mucositis was seen in most patients. One patient was diagnosed with bulb necrosis. CONCLUSION Endobrachytherapy can provide effective treatment for nasopharyngeal carcinoma with an easy application of the brachytherapy procedure.

Abstract
Among the large spectrum of DNA damage induced by radiation, DNA double-strand breaks (DSBs) are considered, to date, as the key-lesions responsible for the cell killing. However, although it was always intuitive to radiobiologists, such a conclusion has only been reached after technical developments and conceptual advances and remains consensual rather than demonstrated formally. In this article, we have reviewed the results that have lead to the conclusion that the assessment of successful DSB repair can be the basis of reliable assays predictive of the clinical response to radiotherapy and some chemotherapeutic treatments. We have discussed a number of technical artifacts, the biases due to the extrapolation of data obtained in yeast and rodent model systems to the human situation and the variety of phenotypes observed in human cells and in particular: 1) the most recent techniques developed, based on immunofluorescence, which have revolutionized our understanding of the molecular events occurring early after irradiation but have also raised the crucial questions about the choice of techniques to assess DSB repair and their specificity for different steps of the repair process; 2) While the homologous recombination repair pathway is predominant in yeasts, its importance in human cells appears less obvious, and raises the problem that the existence of randomized repair events may produce many more errors in human cells than in small genome organisms; 3) the impairment of DSB repair is observed in a plethora of genetic diseases, leading to radiosensitivity, immunodeficiency and sometimes cancer-proneness, but the low frequency and the pleiotropism of such diseases makes difficult the development of a single predictive assay. Therefore, although complete DSB repair appears to be crucial for cell survival, further research is still needed to provide innovative techniques fro measuring repair which can be successfully transferred to the clinic and used to ensure the avoidance of deleterious side-effects to cancer therapies.

Abstract
PURPOSE The objective of this retrospective study was to discuss the epidemioclinical criteria and the therapeutic results of metastatic nasopharyngeal carcinoma. PATIENTS AND METHODS The current study concerned 95 patients with histologically proven nasopharyngeal carcinoma who were metastatic at diagnosis or who had developed late metastasis. We reviewed the epidemioclinical records of all the patients. Patients were treated with chemotherapy (BEC regimen: bleomycin, epirubicin and cisplatin or PBF regimen: bleomycin, 5-fluorouacil and cisplatin) and radiotherapy of pauci metastatic localizations (single or double) or bone metastasis with high risk of compression or fracture+/-associated with locoregional radiotherapy for patients who were metastatic at diagnosis. Response was assessed according to the WHO criteria. Overall survival was calculated according to the Kaplan-Meier method. A long-term disease-free survival was defined from 36 months. RESULTS There were 34 patients who were metastatic at diagnosis and 61 patients who had developed late metastasis. The mean age was 41.5 years (sex-ratio: 3.1). Bone metastases were the most frequent (83%). Objective and complete response rates were respectively 75% and 70%, and 32% and 16% for BEC and PBF regimens. Twenty-five patients received radiotherapy for pauci metastatic localizations, among whom 19 patients who were metastatic at diagnosis received locoregional irradiation. The overall survival probability was of 15% for three years. Eleven patients were long survivors (extremes: 36 and 134 months). CONCLUSION Therapeutic results were comparable to those reported in other series using platin combination chemotherapy. Radiotherapy of metastasis yielded to long-term survival.
