Filter by:The primary objective of this study is to determine the overall survival in patients with stage II (T1-2N1M0) NPC treated with concurrent chemotherapy and radiotherapy. Secondary objectives of the study are to evaluate the disease free survival, and distant metastases free survival of patients with stage II NPC treated with this regimen
The primary objective of this study is to determine the tolerance and overall survival in patients with stage Ⅲ NPC treated with neoadjuvant chemotherapy and concurrent chemoradiation. Secondary objectives of the study are to evaluate the distant metastases free survival, and disease-free survival of patients with stage Ⅲ treated with this regimen.
The primary objective of this study is to determine the tolerance and overall survival in patients with stage ⅣAB NPC treated with neoadjuvant chemotherapy and concurrent chemoradiation. Secondary objectives of the study are to evaluate the distant metastases free survival, and disease-free survival of patients with stage ⅣAB treated with this regimen
Locoregionally advanced nasopharyngeal carcinoma (NPC)(stage III, IV in UICC 2002 Classification) can be divided into two groups according to the risk of metastasis: high-risk metastasis group (T4 or N2-3) and low-risk metastasis group (T3N0-1). In low-risk metastasis group, concurrent chemoradiotherapy (CCRT) might decrease local recurrence and distance metastasis, which benefits overall survival. On the other hand, neoadjuvant chemotherapy is also associated with lower distance metastasis of advanced stage NPC. Nevertheless, CCRT alone or neoadjuvant chemotherapy alone leads to unsatisfactory results regarding to distance metastasis in patients with high-risk metastasis group. In this case, it is utmost important to investigate the new treatment combining neoadjuvant chemotherapy plus CCRT in order to improve overall survival of locoregionally advanced NPC with high-risk metastasis. In our study, in order to investigate the effect and adverse reaction of neoadjuvant chemotherapy plus CCRT on distance metastasis and locoregionally relapse, four hundred patients with high risk of distance metastasis will be randomly divided into two groups, comparing neoadjuvant chemotherapy (DDP+5FU) plus CCRT (DDP) and CCRT (DDP) alone. We aim to find out the best therapeutic regimen with lowest adverse reaction for NPCS with high risk of distance metastasis.
Angiogenesis, the formation of new blood vessel from existing vessels, is essential for tumor growth and metastasis. Antiangiogenic therapies inhibit the growth of genetically stable endothelial cells, and most tumors should starve to death with little acquired resistance. Endostatin has been shown to block endothelial cell proliferation, survival, and migration. Antitumor activity of endostatin protein has been demonstrated in various murine and human tumors in animal model studies without any detectable toxicity. Endostatin gene therapy could directly express the highly bioactive protein in vivo by means of the mechanism of eukaryotic expression system as post-translational modification and folding, as well as overcoming the challenge of the long-term storage and the cumbersome daily administration of endostatin protein. E10A is a replication-deficient recombinant adenovirus containing a wild-type human endostatin transgene constructed from serotype 5 adenovirus (Ad5). Preclinical studies demonstrated that intratumoral injection of E10A provided significant tumor growth inhibition and sustained elevation of endostatin in blood and tumor tissue in hepatocellular carcinoma, nasopharyngeal carcinoma, and tongue cancer animal models. A Phase I clinical trial of E10A we conducted showed that repetitive intratumoral injection of E10A resulted in a small and sustained elevation of endostatin in blood and had a mild antitumor activities with very limited toxicity. The major toxicity was transient and manageable fever. A randomized Phase III trial in nonsmall-cell lung cancer showed endostatin improved response rate and time to tumor progression in combination to chemotherapy. Therefore, we designed a randomized phase II trial to explore the safety and effectiveness of E10A combined with chemotherapy in the treatment of patients with head and neck cancer.

EBV, infection process, immortalization, B lymphocytes, Epithelial cells, co-culture Epstein-Barr virus (EBV) belongs to human γ-herpes viruses. Unlike other human herpes viruses, EBV can only predominately infect two types of human cells: lymphoid cells and epithelial cells and its infection is associated with several human malignancies of these two cell types. The lymphoid cancers associated with EBV infection include Burkitt’s lymphoma, Hodgkin’s disease, B lymphoma in immunodeficient patients and T/NK cell lymphoma. The carcinomas associated with EBV are nasopharyngeal carcinoma and gastric carcinoma. One unique biological feature of EBV is that it can infect and immortalize primary B lymphocytes in vitro into lymphoblastoid cell lines (LCL). So far, limited information is known about the whole EBV infection process and its regulation mechanism for immortalization. In this project, three EBV infection models are setting up to reveal the cellular events and signal transduction pathway possibly involved in EBV infection process and immortalization course of action.
