Active clinical trials for "Head and Neck Neoplasms"

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.

It is the investigators understanding that the combination of clinical trial with laboratory cellular/molecular assay is relevant to the current promising mainstream, the translational research. The design of this trial fulfills this concept and would be a good example conducting in Mackay Memorial hospital.

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at biomarkers in predicting response to treatment in patients with newly diagnosed stage III or stage IV head and neck cancer treated with carboplatin, paclitaxel, and radiation therapy.

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how will patients respond to treatment. PURPOSE: This research study is looking at gene and protein expression patterns in predicting response to cetuximab in patients with recurrent and/or metastatic head and neck cancer.

Objectives: To assess the tolerability of performing optical coherence tomography and/or optical spectroscopy in patients with acute oral mucositis. To determine the feasibility of obtaining optical coherence tomography images and/or fluorescence excitation emission matrices from normal and affected sites in patients with acute oral mucositis. To compare optical data obtained with optical coherence tomography and/or spectroscopy with the clinical appearance and scoring of oral mucositis lesions.

RATIONALE: Drugs used in chemotherapy, such as AP5346 and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This randomized clinical trial is studying the dose of AP5346 to see how well it works compared with the dose of oxaliplatin in treating patients with metastatic and/or unresectable recurrent head and neck cancer.

Clinical experience of with hyperthermia combined with radiotherapy and chemotherapy for recurrent head and neck cancer is limited. The primary goals of hyperthermia combined with CCRT on recurrent head and neck cancer are tumor response rate, while secondary goals are rates of acute and late adverse effects, local control rate, distant metastasis rate, progression-free rate and overall survival rate.

This study will investigate the efficacy and safety of recombinant human endostatin adenovirus combined with chemotherapy for advanced head and neck malignant tumors.

Patients with locally advanced head and neck cancer treated with chemo-radiotherapy have (during and shortly after this treatment) a high risk of developing pneumonia by aspiration. This pneumonia is often associated with a hospital admission and affects the quality of life. The purpose of the study, is to determine whether prophylactic antibiotics may decrease the development of pneumonia. Prophylactic antibiotics means that there are no signs of pneumonia are already

Recently, the HS has been used in head and neck surgery as an alternative to conventional hand-tied ligation for hemostasis, which is a time-consuming procedure. Limited data have been published on the evidence of its safety in ND, especially in radical ND. Researchers investigated the safety and efficacy of the Harmonic scalpel (HS) in neck dissection (ND), while using conventional hand-tied ligation to a minimum, in terms of operating time, blood loss, drainage and complications.
