Filter by:Nasopharyngeal carcinoma (NPC) is one of the most common malignant tumors in southern China and Southeast Asia. While infection with Epstein-Barr Virus (EBV) is believed to be necessary for the development of NPC, non-viral environmental factors have also been implicated to increase the risk of NPC including consumption of salted fish and other nitrosamine containing preserved foods, formaldehyde and wood dust exposure, and cigarette smoking. In addition to environmental factors, it is widely accepted that genetic susceptibility also plays an important role in the pathogenesis of NPC. Polymorphisms in genes involved in nitrosamine metabolism and DNA repair have been suggested to be associated with NPC risk, and various chromosomal regions linked to NPC development have been reported. These associations highlight the role of both environmental and genomic components in the etiology of NPC. There is a longstanding history of international collaborative studies to elucidate the role of environmental and genetic factors associated with NPC between investigators in Taiwan and the USA. A case-control study (375 cases; 327 controls) was conducted in the early 1990s, and a large multiplex family study that was completed in 2006 (358 families; 3,216 individuals). Results from these studies have provided some of the most comprehensive epidemiological evidence regarding factors linked to NPC development to date. As a next logical step, the opportunity now exists to undertake a genome-wide association study of NPC in Taiwan with carefully collected environmental exposure data to systematically examine environmental and genetic factors associated with NPC, and to evaluate gene-gene and gene-environment interactions. The investigators propose a case-control study of 2000 NPC cases (both retrospective [n=800] and prospective [n=1,200]) and 2,000 age-gender-matched hospital controls in northern Taiwan. The study objectives are to: 1) evaluate putative environmental exposures and NPC; 2) assess the effect of genetic factors, including both single nucleotide polymorphism and copy number variation through analysis of both main effect and gene-gene interaction; 3) investigate gene-environment interactions by testing for interactions between significant genome-wide genetic variations and EBV and other identified environmental risk factors; and 4) examine the natural history of EBV infection.
The study try to show the weekly cisplatin based CCRT is not inferior to 3-weekly cisplabe based CCRT in terms of 3-yr progression free survival rate in advanced nasopharyngeal carcinoma
This pilot clinical trial studies L-lysine in treating oral mucositis in patients undergoing radiation therapy with or without chemotherapy for head and neck cancer. L-lysine may lessen the severity of oral mucositis, or mouth sores in patients receiving radiation therapy with or without chemotherapy for head and neck cancer
The purpose of this study is to evaluate the efficacy (clinical benefit rate) of MVA EBNA1/LMP2 vaccine in patients with persistent, recurrent or metastatic nasopharyngeal carcinoma, and its impact on disease progression.
Objectives: Primary objective - To determine the efficacy of Foscan-PDT compared with Brachytherapy for recurrent or persistent NPC, as determined by macroscopic clinical examination, CT scan and biopsy. The primary endpoint is complete tumour response at 6 months. Secondary objective: - To determine the response rates, e.g. presence of tumour on endoscopy, time to progression and overall survival in patients treated with Foscan-PDT compared with brachytherapy - To determine the quality of life, as derived from the University of Washington Quality of Life questionnaire in patients treated with Foscan-PDT compared with brachytherapy - To evaluate the safety of Foscan-PDT compared with brachytherapy in terms of adverse events and serious adverse events.
Nimotuzumab is an IgG1 humanized monoclonal antibody that recognized an epitope located in the extra cellular domain of the human epidermal growth factor receptor (EGFR). Clinical trials are ongoing globally to evaluate nimotuzumab in different indications. Nimotuzumab has been granted approval for use in squamous cell carcinoma of head and neck (SCCHN), glioma and nasopharyngeal cancer in different countries. The Clinical efficacy has been shown in adult with head and neck cancer. The study assessed the clinical efficacy, and safety of the combination of Nimotuzumab administered concomitantly with chemotherapy and radiotherapy in patients with advanced nasopharyngeal cancer.
This research is being done to determine whether viral thymidine kinase (TK) expression in Epstein-Barr virus (EBV) and Kaposi's sarcoma herpesvirus (KSHV) virus-associated tumors is sufficient to image.
Patients have a type of cancer called nasopharyngeal carcinoma (NPC) that has either come back or not gone away after the best known standard treatments. Most patients that respond to chemotherapy once their NPC tumors have come back have been treated with a platinum-based medication like cisplatin. However, since many patients are given cisplatin during their initial treatment for NPC, in this study, they will be treated with another platinum-based chemotherapy medicine that has been used in patients with NPC called carboplatin. In this study, carboplatin will be used in combination with another drug called docetaxel. Other studies in patients with advanced head and neck cancer have shown that docetaxel can cause tumors to respond better and allow patients to survive longer when added to the standard treatments for those diseases. Some patients with NPC show evidence of infection with the virus that causes infectious mononucleosis, known as the Epstein Barr virus (EBV), before or at the time of their cancer diagnosis. EBV is found in the cancer cells of almost all patients with advanced stage disease, suggesting that it may play a role in causing NPC. Previously, patients have been treated with high-risk NPC using EBV-specific cytotoxic T cells. These cells are grown in the laboratory and taught to recognize and attack EBV infected cells. In the past, patients were either given the cells alone or just after they had received a medication to briefly lower their white blood cell count. In both cases, many patients had their tumors shrink and in some cases completely disappear after being treated with these EBV-specific cytotoxic T cells. Investigators have now decided to look at how patients with NPC and their tumors respond to the treatment combination of chemotherapy and EBV-CTL. Patients are being asked to participate in this study since the NPC tumor is associated with EBV and has either come back or not responded to standard treatment. This combination of chemotherapy and EBV-CTLs is an investigational treatment not approved by the Food and Drug Administration. The purpose of this study is to see how relapsed or refractory, EBV-associated NPC tumors respond when treated with carboplatin and docetaxel followed by EBV-CTL.

To determine the association between VEGF-C,-D expression with COX-2 expression and clinico-pathologic variables in colorectal cancer and Nasopharyngeal carcinoma 3. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma Lymphangiogenesis and factors modulating lymphangiogenesis are associated with clinico-pathological outcome in Nasopharyngeal carcinoma and colorectal cancer. Celecoxib down-regulates lymphangiogenesis Archival colorectal cancer and Nasopharyngeal carcinoma tumor specimens will be obtained from the Department of Pathology. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma, the investigators intend to analyze archived specimens collected in a previously conducted study. Colorectal tumor and nodal specimens and Nasopharyngeal carcinoma primary will be examined for MVD, LVD and growth factor expression using established haematoxylin and eosin and immunohistochemical techniques. Quantification of LVD and MVD shall be performed by two pathologists blinded to clinico-pathological variables using standardised methods.
This study is aimed to estimate the effectiveness of an Epstein-Barr virus (EBV) serology-based screening program to reduce nasopharyngeal carcinoma (NPC) mortality in a cluster randomized controlled trial in an NPC high-risk population. Sixteen towns in Sihui and Zhongshan Cities, China will be selected, with eight allocated to the screening group and eight to the control group. Cantonese residents aged 30-69 years with no history of NPC will be included. Residents in the screening towns will be invited to undergo serum EBV VCA/EBNA1 IgA antibody tests.
