Filter by:A research study of the drug amrubicin in patients with cancer of the thymus (thymoma or thymic carcinoma). We hope to learn whether this drug is an effective and safe treatment for thymic cancers.
Background: - The current standard of care for advanced lung cancer and cancers of the thymus consists primarily of chemotherapy treatment. The drugs used for chemotherapy depend on the classification of the cancer in different categories that are based on the appearance of the cancer in the microscope. Though this approach has been proved to be useful in some ways, the survival rates of individuals with lung cancer and cancers of the thymus are still very poor. Recent research has shown that several genetic abnormalities play an important role in the development and growth of lung cancer and cancers of the thymus, and that it is possible to improve treatment success rates with drugs that specifically target some of the abnormal genes. Researchers are interested in determining whether it is possible to analyze the genes of patients with lung cancer and cancers of the thymus in order to provide personalized treatment with drugs that target the specific gene abnormalities. Objectives: - To evaluate the effectiveness of genetic analysis in determining targeted therapy for individuals with advanced non-small cell lung cancer, small cell lung cancer, and thymic cancer. Eligibility: - Individuals at least 18 years of age who have been diagnosed with either lung cancer or a cancer of the thymus that is not considered to be curable with the use of surgery or radiation therapy. Design: - Participants will be screened with a full medical history and physical examination, blood and urine tests, and tumor imaging studies. Participants will have a tumor biopsy or provide previously collected tumor tissue for study. - Based on the results of the tumor biopsy study, participants will be separated into different treatment groups: - Participants with epidermal growth factor receptor (EGFR) gene mutation will receive a drug called erlotinib, which inhibits a protein called EGFR that is thought to be a key factor in the development and progression of some cancers. - Participants with Kirsten rat sarcoma virus (KRAS), proto-oncogene B-Raf (BRAF), Harvey Rat sarcoma virus (HRAS), or NRAF gene mutations will receive a drug called AZD6244, which inhibits a protein called methyl ethyl ketone (MEK) that is thought to be a key factor in the development and progression of some cancers. - Participants with phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA), protein kinase B (AKT), or phosphatase and tensin homolog (PTEN) gene mutations will receive a drug called MK-2206, which inhibits a protein called AKT that is thought to be a key factor in the development and progression of some cancers. - Participants with KIT or platelet-derived growth factor receptor A, (PDGFRA) gene mutations will receive a drug called sunitinib, which inhibits some proteins that are thought to be key factors in the development and progression of some cancers, including kidney cancer. - Participants who have -erb-b2 avian erythroblastic leukemia viral oncogene homolog 2 (ERBB2) gene mutation or amplification will receive a drug called lapatinib, which inhibits some proteins that are thought to be key factors in the development and progression of some cancers, including breast cancer. - Participants who do not have any of the genetic abnormalities described above will be offered different options for treatment, including standard of care chemotherapy or treatment with investigational agents in a different research protocol. - After 6 weeks of treatment, participants will have imaging studies to evaluate the status of their cancer. Treatment will continue as long as participants tolerate the drugs, and the disease does not progress. - Participants who benefit from the first treatment but eventually develop resistance and progression of their cancer will be offered the chance to have a second tumor biopsy and undergo a different treatment for their cancer.
The intent of the study is to assess the antitumor activity of PHA-848125AC in patients with recurrent or metastatic, unresectable malignant thymoma previously treated with multiple lines of chemotherapy.
Allogeneic transplant from a matched sibling for the treatment of a variety of illnesses including bone marrow failure states, leukemias, myelodysplastic or myeloproliferative syndromes, lymphoma, or myeloma using a nonmyeloablative preparative regimen.
Background: - Recent research has shown that causing an immune response to tumor cells may help slow or stop the growth of tumors. One treatment that has come from this research involves collecting and modifying a cancer patient's tumor cells in the laboratory, then returning the cells to the patient as a vaccine to encourage the immune system to respond to them. Researchers are interested in testing tumor cell vaccines with an experimental drug called ISCOMATRIX , which can be added to a vaccine in order to elicit a stronger immune response in the body. ISCOMATRIX has not been approved for sale and use in any country and its use is still experimental, though it has been tested and used safely in other clinical studies. Researchers are also interested in determining whether the anti-inflammatory drug celecoxib will improve the body's immune reaction if given with the vaccine. Objectives: - To assess the safety and effectiveness of tumor cell vaccines given with ISCOMATRIX and celecoxib in the treatment of lung and esophagus cancers. Eligibility: - Individuals at least 18 years of age who have primary small cell or non-small cell lung cancer, esophageal cancer, or pleural mesothelioma that can be removed by surgery. - Only individuals whose tumor cells are able to produce a tumor cell line for vaccine development will be eligible for treatment. Design: - Participants will be screened with a physical examination and medical history, and will have tumor tissue collected during their surgery to determine whether the tumor cells can be used to produce a vaccine. - Participants will take celecoxib twice daily for 7 days before having the first tumor cell vaccination. Participants will also have leukapheresis to collect blood cells for testing before the first vaccination. - Participants will receive one vaccine (which may be given in two shots) monthly for 6 months, and will continue to take celecoxib twice daily. One month after the 6th vaccine shot, participants will have another leukapheresis and skin test. If these tests show that a participant is responding to the vaccine, additional vaccines will be given every 3 months for up to 2 years. - Participants will have a physical exam and lab tests before each vaccination, blood samples and imaging studies every 3 months, and a skin test every 6 months. - Participants will have regular followup visits with imaging studies and blood samples for up to 5 years after the first vaccination, or until a new tumor develops.
This an an open-label study to define the safety profile and the maximum tolerated dose and confirm the clinical effective dose of palifosfamide-tris given intravenously in combination with etoposide and carboplatin in a wide range of cancers which etoposide and carboplatin are normally given. Once the maximum dose of palifosfamide-tris is determined,a Phase II study using the 3 agents combined will begin.
Background: - Certain types of lung, esophageal, or thymic cancers and mesotheliomas have specific antigens (protein molecules) on their surfaces. Research studies have shown that giving a vaccine that contains antigens similar to these may cause an immune response, which may keep tumors from growing. Researchers are also interested in determining whether the chemotherapy drug cyclophosphamide and the anti-inflammatory drug celecoxib may help the vaccine work better, particularly in patients with lung cancer. Objectives: - To evaluate the safety and effectiveness of tumor cell vaccines in combination with cyclophosphamide and celecoxib in patients with cancers involving the chest. Eligibility: - Individuals at least 18 years of age who have had surgery for small cell or non-small cell lung cancer, esophageal cancer, thymoma or thymic carcinoma, and malignant pleural mesothelioma. Design: - Following recovery from surgery, chemotherapy, or radiation, participants will have leukapheresis to collect lymphocytes (white blood cells) for testing. - Participants will receive celecoxib and cyclophosphamide to take twice a day at home, 7 days before the vaccine. - Participants will have the vaccine in the clinical center (one or two shots per month for 6 months), and will stay in the clinic for about 4 hours after the vaccine. Participants will keep a diary at home of any side effects from the vaccine, and will continue to take cyclophosphamide and celecoxib. - One month after the sixth vaccine, participants will provide another blood sample for testing, and if the tests are satisfactory will return to the clinic every 3 months for 2 additional vaccines. - Participants will return to clinic for follow-up physical examinations, lab tests, and scans every 3 months for 2 years and then every 6 months for up to 3 years.
The purpose of this study is to study characteristics of patients with thymoma in Chulalongkorn hospital between 2003-2007.
Although the association between thymic hyperplasia / thymoma and autoimmune myasthenia gravis has been known for some time, the question of causality remains uncertain. Recent research findings indicate, however, that especially in myasthenia patients with thymomas a non-physiological export of naive CD4 + T-cells can take place by the tumour and this could possibly play an important role in the pathogenesis of myasthenia gravis. The investigators want to analyse the functionality and specificity of t-cells generated in thymomas as well as the effect of thymectomy on the immune system.
Background: - Tumors of the thymus are rare and can be treated with surgery, but it is often difficult to determine whether a thymic tumor is malignant based on biopsy alone and the long-term survival rate is less than 50 percent. Because thymic tumors are so rare, most treatment knowledge comes from a relatively small series of cases, and the choice of treatment usually depends on the hospital or clinic staff's experience and familiarity with a given chemotherapy and surgery regimen. - Belinostat is an investigational anticancer drug that has not yet been approved by the Food and Drug Administration for use in any cancer. Researchers are interested in determining whether belinostat can be combined with conventional chemotherapy to safely and effectively treat advanced thymic cancer. Objectives: - To determine a safe and tolerable dose of belinostat that can be given in combination with cisplatin, doxorubicin, and cyclophosphamide. - To determine if belinostat (combined with the abovementioned standard chemotherapy regimen) is effective against thymic cancer cells. Eligibility: - Individuals at least 18 years of age who have been diagnosed with advanced or recurrent thymic malignancy that is not considered to be curable with surgery or radiation therapy, and who have not received previous chemotherapy treatment. Design: - Participants will be screened with a physical exam, blood tests, and imaging studies as directed by the study researchers. - Participants will receive six 21-day cycles (18 weeks) of treatment with belinostat in combination with cisplatin, doxorubicin, and cyclophosphamide. The treatment will require continuous infusion over 3 days, and participants will remain in the treatment center during this time. Participants will have regular blood tests, clinic visits, and imaging studies during the treatment period. - Participants who complete the six treatment cycles with no severe side effects may be offered the option to continue treatment with belinostat alone. - After the 18-week study period, participants will return for regular follow-up exams for at least 4 weeks, and will be asked to remain in contact with the study researchers once a year to continue to study long-term effects....
