Active clinical trials for "Thymoma"

Background: Cisplatin-containing chemotherapy is the standard of care for advanced thymoma and thymic carcinoma that cannot be treated with surgery. New options for treatment are necessary in patients with advanced thymoma and thymic carcinoma that have progressed on cisplatin-containing therapy. IMC-A12 is a new (experimental) agent that has not yet been approved by the Food and Drug Administration. IMC-A12 blocks the Insulin-like Growth Factor 1 receptor (IGF-1R). IGF-1R is found on many types of cancer cells, including cancer of the thymus, and is thought to play an important role in helping these cells to grow and divide. Objectives: To determine if IMC-A12 has an effect on tumor growth in patients with cancer of the thymus. To evaluate the safety and tolerability of IMC-A12 in treatment for cancer of the thymus. Eligibility: - Individuals older than 18 years of age who have cancer of the thymus (thymoma, thymic carcinoma, or thymic carcinoid tumors) that has progressed in spite of standard treatment. Design: Treatment will take place in 21-day cycles. Patients will receive one dose of IMC-A12 intravenously once every 3 weeks at the Clinical Center. During the Clinical Center visits, researchers will perform study tests and procedures to see how the study drugs are affecting the body. Patients will undergo a number of tests and procedures during the treatment cycle, including physical examinations, blood and urine samples for standard tests, imaging studies (ultrasound, magnetic resonance imaging (MRI) or computed tomography (CT) scans) to evaluate tumor growth, and blood and urine samples to evaluate the amount of IMC-A12 in the body. Patients may continue to take the drug as long as there are no adverse side effects and as long as the tumor does not grow.

Background: Cisplatin-containing chemotherapy is the standard treatment for advanced tumors of the thymus that cannot be removed surgically. New treatment options are needed for patients with advanced tumors of the thymus that do not improve with cisplatin-containing therapy. Belinostat is a drug that inhibits enzymes called histone deacetylase. Histone deacetylase inhibitors have shown promising activity in many cancers and may be useful in treating patients with thymic tumors. Objectives: -To assess the safety and effectiveness of belinostat for treatment of malignant thymic tumors in patients who failed after standard treatment. Eligibility: -Patients 18 years of age or older with an advanced thymic tumor that has progressed after treatment with platinum-containing chemotherapy. Design: Patients receive belinostat treatment in 21-day cycles. The drug is given as an infusion through a vein during days 1 through 5 of each cycle. Treatment cycles continue as long as the medicine is tolerated and the cancer does not worsen. Patients have a physical examination and several blood tests during every cycle. Patients have an electrocardiogram every cycle before starting the belinostat infusion and again on the last day of the infusion. Patients undergo computed tomography (CT) or other imaging test, such as ultrasound or MRI, every two cycles to evaluate the response of the tumor to treatment. Tumor tissue obtained from a previous biopsy is used for research purposes.

The purpose of this study is to determine the rate of response with the combination of erlotinib and bevacizumab in previously treated patients with thymoma or thymic carcinoma, and to determine potential molecular markers that may predict response to therapy in patients with thymoma or thymic carcinoma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one chemotherapy drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of carboplatin combined with paclitaxel in treating patients who have advanced thymoma.

According to the existing literature reports, the misdiagnosis rate of CT is as high as 22% - 68%. Thymic cyst and lymphoma are usually misdiagnosed as thymoma, resulting in many unnecessary operations; In addition, traditional imaging technologies can also cause a missed diagnosis rate of about 7%, which is common in the missed diagnosis of asymptomatic thymoma, which delays the opportunity of treatment. Therefore, in order to accurately treat thymic tumors, the existing diagnostic methods of thymic tumors need to be further optimized. Our previous retrospective study found that the level of IL-8 + initial T cells can well distinguish thymoma from other types of anterior mediastinal tumors, and the sensitivity and specificity are close to 95%.

For patients with unresectable or recurrent disease, radiation is routinely administered, often in combination with systemic chemotherapy. However, because of wide range of radiation, more complications of conventional radiotherapy limit its treatment dose. The local recurrence rates of conventional radiotherapy are dissatisfied.Stereotactic body radiation therapy(SBRT) well solved the problem above. On the one hand, by improving the single dose, it not only shortens the total radiation treatment, but also increases the total dose of equivalent biological effects.

This study is important to demonstrate if single agent activity is noted for patients with thymic tumors over expressing c-kit and/or PDGF. If this current trial is positive, it opens the door to evaluate other combination of drugs with imatinib in thymic tumors.

This is a phase II study for patients with thymoma or thymic carcinoma thought to be at significant risk for recurrence following surgical removal. This study involves the use of combined chemotherapy and radiation therapy prior to surgery, in hopes of increasing the chances of complete resection. The chemoradiotherapy protocol is one which has been used extensively for other diseases, and the side effects are therefore well-documented. Patients with thymomas thought to be at significant risk for recurrence (by x-ray and pathology criteria) will be allowed to participate, and will undergo combined chemotherapy with radiation to the chest followed by surgical removal of the tumor and postoperative chemotherapy. The main outcome measured will be the rate of pathological complete response (e.g. no active tumor in the resected specimen) to the preoperative treatment. Patients will receive postoperative treatment based on surgical and pathologic criteria.

This is a multi-center, open-label, dose escalation study to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, and maximum tolerated dose (MTD) of QBS10072S in patients with advanced or metastatic cancers with high LAT1 expression. The MTD of QBS10072S will be confirmed in patients with relapsed or refractory grade 4 astrocytoma.

The purpose of this study was to evaluate the safety and perioperative outcomes of the subxiphoid approach versus the lateral intercostal approach thoracoscopic thymectomy for Masaoka-Koga I-II thymoma.
