Filter by:Examine neutrophil extracellular traps (NETs) formation, in relation to other neutrophil functions like chemotaxis, superoxide production, hydrogen peroxide production, and the presence of myeloperoxidase, in pediatric patients undergoing chemotherpy for solid and hematological malignancies. This data could shed new light on the mechanism responsible for the increased susceptibility to infection among these patients and aid in improving their prophylactic antimicrobial treatment. NETs formation against tumor cell lines and their ability to kill tumor cells will also be examined. The finding of NETs activity against tumor cells could have a major contribution to the investigators understanding of the function of the immune system against cancer.
The nonpolypoid colorectal neoplasms (NP-CRNs) are relatively common in patients with gastrointestinal alarm systoms. The depressed lesions have a greater risk of having cancer than flat and polypoid lesions.
This phase II clinical trial studies how well two donors stem cell transplant work in treating patients with high-risk hematologic malignancies. After receiving radiation to help further treat the disease, patients receive a dose of donors' T cells. T cells can fight infection and react against cancer cells. Two days after donors' T cells are given, patients receive cyclophosphamide (CY) to help destroy the most active T cells that may cause tissue damage (called graft versus host disease or GVHD). Some of the less reactive T cells are not destroyed by CY and they remain in the patient to help fight infection. A few days after the CY is given, patients receive donors' stem cells to help their blood counts recover. Using two donors' stem cell transplant instead of one donor may be more effective in treating patients with high-risk disease and may prevent the disease from coming back.
The goal of this clinical research study is to find the highest tolerable dose of the combination of erlotinib and pralatrexate that can be given to patients with advanced cancer. The safety of the drug combination will also be studied. Pralatrexate is designed to block the body's ability to make folic acid, a protein that may help cancer tissue to develop and spread. Erlotinib hydrochloride is designed to block proteins that are thought to cause cancer cells to grow. Erlotinib may help slow the growth of tumors.
This phase I clinical trial studies vemurafenib with sorafenib tosylate or crizotinib in treating patients with advanced malignancies with BRAF mutations. Sorafenib tosylate and crizotinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Sorafenib tosylate may also stop the growth of advanced malignancies by blocking blood flow to tumors. Drugs used in chemotherapy, such as vemurafenib, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving vemurafenib together with sorafenib tosylate or crizotinib may kill more cancer cells.
The purpose of this research study is to learn about the effectiveness of using lower-intensity radiation and chemotherapy to treat human papillomavirus (HPV) associated low-risk oropharyngeal and/or unknown primary squamous cell carcinomas of the head and neck. The cure rate for this type of cancer is estimated to be high, > 90%. The standard treatment for this cancer is 7 weeks of radiation with 3 high doses of cisplatin. Sometimes surgery is performed afterwards. This standard regimen causes a lot of side effects and long term complications. This study is evaluating whether a lower dose of radiation and chemotherapy may provide a similar cure rate as the longer, more intensive standard regimen. Patients in this study will receive 1 less week of radiation and a lower weekly dose of chemotherapy followed by a limited surgical evaluation.
This is a Randomized Multicentre study Comparing GCSF Mobilized Peripheral Blood and GCSF stimulated Bone Marrow in Patients undergoing matched sibling Transplantation for Haematologic Malignancies.
This phase I trial studies the side effects and best dose of temsirolimus and metformin hydrochloride in treating patients with cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment (advanced or metastatic). Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Metformin hydrochloride is a drug used to treat diabetes that may also prevent or slow the growth of cancers. Giving temsirolimus and metformin hydrochloride together may kill more tumor cells.
This study will assess safety, tolerability, maximum tolerated dose or recommended dose for expansion of TAS266 administered by IV infusion to patients with advanced solid tumors.
The purpose of this study is to determine a tolerable dose of radiation delivered by the CyberKnife system in two groups of patients with hepatocellular carcinoma (HCC).
