Filter by:The purpose of this study is to examine the valu of individually dose escalated radiotherapy compared with a standard dose of radiotherapy combined with standard concomitant chemotherapy for patients with locally advanced non small cell lung cancer (stage III) with good performance status.
This study aims to use a type of radiation (adaptive radiotherapy) to deliver curative-intent treatment to patients with non-small cell lung cancer, whose tumors would otherwise be too large for standard curative treatment. The study will use adaptive radiotherapy to achieve these goals. Adaptive radiotherapy is a process whereby treatment plans are modified during the course of treatment due to patient and tumor variations (ie. weight loss or tumor shrinkage). This may allow for dose escalation, while limiting the side effects.
The purpose of the first part of the study is to evaluate the safety, tolerability, and pharmacokinetics of ascending doses of gemcitabine elaidate in combination with cisplatin given to patients with advanced solid tumors, and to select a dose for further evaluation in the second part of the study. The purpose of the second part of the study is to determine the safety, tolerability, and exploratory clinical activity of gemcitabine elaidate in combination with cisplatin given to patients with Stage IIIb/IV non-small-cell lung cancer (NSCLC).
Radiotherapy, preferably combined with chemotherapy, is the treatment standard for locally advanced, unresectable non-small cell lung cancer (NSCLC). The tumor response to different therapy protocols is variable, with hypoxia known to be a major factor that negatively influences treatment effectiveness. Visualisation of tumor hypoxia prior to the use of modern radiation therapy strategies, such as intensity modulated radiation therapy (IMRT), might allow higher dose applications to the target volume, leading to improvement of therapy outcome. 18F-fluoromisonidazole dynamic positron emission tomography and computed tomography (18F-FMISO dPET-CT) and functional magnetic resonance imaging (functional MRI) are attractive strategies for imaging tumor hypoxia. The HIL trial is a single centre pilot study combining multimodal hypoxia imaging with 18F-FMISO dPET-CT and functional MRI and intensity modulated radiation therapy (IMRT) in patients with inoperable stage III NSCLC. 15 patients are recruited in the study. All patients undergo serial 18F-FMISO dPET-CT and functional MRI before treatment, at week 5 of radiotherapy and 6 weeks post treatment. Radiation therapy is performed as inversely planned IMRT after four dimensional computed tomography (4D-CT) based target volume definition. Hypoxia imaging is not included in target volume definition or IMRT dose prescription. Objectives of the trial are to characterize the correlation of 18F-FMISO dPET-CT and functional MRI for tumor hypoxia imaging in NSCLC and evaluate possible effects of radiation therapy on tumor re-oxygenation. Further objectives include the generation of data regarding the prognostic value of 18F-FMISO dPET-CT and functional MRI for locoregional control, progression free survival and overall survival of NSCLC treated with IMRT, which will form the basis for larger clinical trials focusing on possible interactions between tumor oxygenation and radiation outcome.
Certain genetic factors can affect a patient's potential sensitivity to therapeutic drugs and other agents. There is a factor called ISG15 which might help doctors better identify patients with advanced non-small cell lung cancer (NSCLC) whose tumors may be more sensitive to the drug called Irinotecan. This factor is elevated in roughly 30% of NSCLC cases. Irinotecan is an agent that inhibits the enzyme called topoisomerase I that is involved in cell growth, and it has been FDA approved for 17 years for another type of cancer.
This research study is looking at an alternative way of delivering radiation therapy with protons. Protons are tiny particles with a positive charge that can be controlled to travel a certain distance and stop inside the body. In theory, this allows better control of where the radiation dose is delivered as compared to photons. Information from other research studies suggests that proton radiation may help to reduce unwanted side effects from radiation and allow an increase in radiation dose that increase the odds of tumor killing. The purpose of this study is to determine the safest dose of proton radiation therapy to give in combination with standard chemotherapy in participants with Non-Small Cell Lung Cancer (NSCLC).
The primary objective for this trial is to determine the biological ability of apricoxib to decrease T reg cells in the peripheral blood and tumor infiltrating lymphocytes in subjects compared to those who have not in subjects with early stage Non-small Cell Lung Cancer (NSCLC). The secondary objectives are to determine the efficacy of apricoxib to inhibit CD4+CD25+ T reg and FOXP3 function and exploration of COX-2 dependent biomarkers of apoptosis resistance, angiogenesis, invasion, and immunity.
Stereotactic body radiation therapy (SBRT) is a special form of treatment which pinpoints high doses of radiation directly to cancer. Standard radiation (or photon radiation) is commonly used for SBRT to treat Non-Small Cell Lung Cancer (NSCLC). Proton beam radiation is a special type of radiation only available at a few institutions in the US and has not been previously used in SBRT to treat NSCLC. The use of protons for SBRT may improve the accuracy of the treatment and may help to minimize the dose delivered unnecessarily to healthy tissue. In this study, the investigators are evaluating the safety and effectiveness of proton-based SBRT for early-stage NSCLC located in the periphery of the lung.
The goal of this clinical research study is to compare 2 types of radiotherapy, stereotactic body photon radiotherapy (SBRT) and stereotactic body proton radiotherapy (SBPT). Researchers would like to compare the side effects, quality of life, and cancer control.
Tumour angiogenesis has been identified to play a critical role in tumour growth and this knowledge has led to the identification of new targets for cancer therapy. Multiple angiogenic factors are involved in the regulation of angiogenesis, among them VEGF (vascular endothelial growth factor) and its receptor are of crucial relevance. The inhibition of VEGF signaling by monoclonal antibodies or small molecules (kinase inhibitors) has already been successfully established for the treatment of different cancer entities and multiple new drugs are being tested in clinical trials. The ever-expanding list of antiangiogenic agents being available in the near future will raise the questions when to use which agent and in which sequence. As a consequence biomarkers are going to be indispensible tools for choosing the most effective drugs and to predict dosing and resistance. The present project is based on an academic clinical trial in which patients suffering from different cancer types (colorectal cancer, non-small cell lung cancer, renal cell cancer and hepatocellular cancer) treated routinely with antiangiogenic agents will be included. Consecutive serum and blood probes will be taken and will be examined and correlated with functional imaging and the clinical course. The following parameters have been selected: soluble markers in the plasma (VEGF, bFGF, ICAM, sVGFR-2 IL-8, SDF1 and Dickkopf 3) and cellular parameters like circulating endothelial cells (CEC) and circulating endothelial progenitor cells (CEPs). In conclusion, the present project is screening for potential biomarkers and biomarker combinations relevant for antiangiogenic drugs in different tumour types. The predictive value of such profiles should then be evaluated in larger cohorts. In the future such profiles could possibly help clinicians to use these agents more effectively and therefore also more economically.
