Filter by:There are two study questions we are asking in this randomized phase II/III trial based on a blood biomarker, Epstein Barr virus (EBV) deoxyribonucleic acid (DNA) for locoregionally advanced non-metastatic nasopharyngeal cancer. All patients will first undergo standard concurrent chemotherapy and radiation therapy. When this standard treatment is completed, if there is no detectable EBV DNA in their plasma, then patients are randomized to either standard adjuvant cisplatin and fluorouracil chemotherapy or observation. If there is still detectable levels of plasma EBV DNA, patients will be randomized to standard cisplatin and fluorouracil chemotherapy versus gemcitabine and paclitaxel. Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, fluorouracil, gemcitabine hydrochloride, and paclitaxel work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving cisplatin and fluorouracil is more effective than gemcitabine hydrochloride and paclitaxel after radiation therapy in treating patients with nasopharyngeal cancer.
This is a randomized parallel control trial to evaluate whether radical loco-regional Radiotherapy can prolong survival time of initial untreated metastatic nasopharyngeal carcinoma.
Patients have nasopharyngeal carcinoma (NPC). This study is a gene transfer research study using special immune cells. Most patients with NPC show evidence of infection with the virus that causes infectious mononucleosis Epstein Barr virus (EBV) before or at the time of their diagnosis. EBV is found in the cancer cells of almost all patients with advanced stage NPC, suggesting that it may play a role in causing the disease. The cancer cells infected by EBV are able to hide from the body's immune system and escape destruction. We want to see if special white blood cells, called T cells, that have been trained to recognize and kill special parts of EBV infected cells can survive in patient's blood and affect the tumor. We already have given EBV-specific cytotoxic T cells to 30 patients with active NPC and have seen anti-tumor activity in 14 of 30 patients. We are now trying to find out if we can improve this treatment. First, we want to give T cells where more of the cells recognize at least two of the four EBV proteins expressed on NPC cells. We call these cells NPC-specific cytotoxic T cells. Second, we found that T cells work better if we add a receptor to the T cells called DNR (Dominant Negative Receptor). DNR makes T cells resistant to TGFbeta, a factor secreted by cancer cells that helps them escape being killed by the immune system. In this study we will therefore place the DNR gene into NPC-specific T cells (DNR.NPC-specific T cells). In other clinical studies using T cells, some investigators found that giving chemotherapy before the T cell infusion can improve the amount of time the T cells stay in the body and therefore the effect the T cells can have. Giving chemotherapy before a T cell infusion is called lymphodepletion since the chemotherapy is specifically chosen to decrease the number of lymphocytes in the body. Decreasing the number of patient's lymphocytes first should allow the T cells we infuse to expand and stay longer in their body, and potentially kill cancer cells more effectively. The chemotherapy we will use for lymphodepletion is a combination of cyclophosphamide and fludarabine. Cyclophosphamide and fludarabine are the chemotherapy agents most commonly used for lymphodepletion in immunotherapy clinical trials.
The purpose of this study is to determine if the screening of nasopharyngeal carcinoma using plasma Epstein-Barr virus DNA analysis would result in the detecting NPC cases at earlier stages and improve survival.
The purpose of this study is to compare induction chemotherapy (gemcitabine+cisplatin) plus concurrent chemoradiotherapy (CCRT) with CCRT alone in patients with locoregionally advanced nasopharyngeal carcinoma(NPC), in order to confirm the value of induction chemotherapy in NPC patients.
This phase I trial studies the side effects and best dose of paclitaxel albumin-stabilized nanoparticle formulation when given together with carboplatin followed by chemoradiation in treating patients with recurrent head and neck cancer. Drugs used in chemotherapy, such as paclitaxel albumin-stabilized nanoparticle formulation, carboplatin, fluorouracil, and hydroxyurea, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving paclitaxel albumin-stabilized nanoparticle formulation followed by chemoradiation therapy may be an effective treatment for head and neck cancer.
The purpose of this study is to compare the efficacy and toxicity of docetaxel-cisplatin neoadjuvant chemotherapy followed by concurrent radiotherapy with cetuximab or weekly cisplatin in locally advanced nasopharyngeal carcinoma.
The investigators designed this study to evaluate the efficiency and the acute toxicities of recombinant human endostatin (endostar) combined with chemotherapy in the metastatic nasopharyngeal carcinoma (NPC).
The purpose of this study is to compare induction chemotherapy (docetaxel+cisplatin+fluorouracil) plus concurrent chemoradiotherapy with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma (NPC), in order to confirm the value of induction chemotherapy in NPC patients.
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.
