Filter by:This study aims to prospectively document the population characteristics, imaging findings, pathological features, prognostic factors, etc., of patients with mediastinal tumors. Clinical information will be structured and processed, and it is recommended to establish a mediastinal tumors database at Peking Union Medical College Hospital. The goal is to provide support for the quality of diagnosis and treatment, clinical protocols, and medical decision-making related to mediastinal tumors.
To observe the efficacy and toxicities of heavy ion radiation therapy for locally advanced or advanced primary thymic epithelial malignant tumor received R2 resection. The primary endpoint was progression-free survival and toxicities, and the secondary endpoint was local relapse-free survival, overall survival and cause-specific survival.
Thymic epithelial tumors are rare neoplasms in the anterior mediastinum. The cornerstone of the treatment is surgical resection. Administration of postoperative radiotherapy is usually indicated in patients with more extensive local disease, incomplete resection and/or more aggressive subtypes, defined by the WHO histopathological classification. In this classification thymoma types A, AB, B1, B2, B3, and thymic carcinoma are distinguished. Studies have shown large discordances between pathologists in subtyping these tumors. Moreover, the WHO classification alone does not accurately predict the risk of recurrence, as within subtypes patients have divergent prognoses. The investigators will develop AI models using digital pathology and relevant clinical variables to improve the accuracy of histopathological classification of thymic epithelial tumors, and to better predict the risk of recurrence. In this multicentric and international project three existing databases will be used from Rotterdam, Maastricht and Lyon. For all models one database will be used to build AI models, and the other two for external validation. The ultimate goal of this project is to develop AI models that support the pathologist in correctly subtyping thymic epithelial tumors, in order to prevent patients from under- or overtreatment with adjuvant radiotherapy.
PURPOSE: To evaluate the efficacy and safety of Rivoceranib in patients with metastatic thymic epithelial tumors who developed resistance on first-line therapy. Study Design: Patients with histologically confirmed metastatic thymic epithelial tumors who meet the inclusion/exclusion criteria will be enrolled in this study. In Stage 1, 18 subjects will be enrolled to receive study medication. If a tumor response is observed in at least 5 of these subjects, the study will proceed to Stage 2 to enroll the remaining subjects, or the study will be stopped early due to lack of clinical benefit of the investigational product. The trial will be considered clinically valid if a response is observed in 11 or more subjects out of a total of 33 subjects. Investigational product(Rivoceraniv 700 mg) will be administered until disease progression, development of intolerable adverse events, death, withdrawal of consent by the subject, or when, in the opinion of the principal investigator, it is inappropriate or impossible to continue the study. Imaging studies (CT or MRI) will be performed every 8 weeks (+,- 1 week) for C1D1 through 12 months and every 12 weeks (+,- 1 week) after 12 months, and the results will be used to assess tumor response according to RECIST v1.1 criteria. Safety will be assessed at C1D1, C1D7, and each scheduled visit thereafter.
Thymic malignancies are the most common tumors of the anterior mediastinum, though surgery and radiation often effectively treat thymic carcinomas, a minority continue to progress and eventually lead to death. Therefore, there is an unmet need for more effective therapies for thymic malignancies. Considering the role of molecular alterations has yet to be defined in the treatment of thymoma and thymic malignancies, there is an urgent recognition that molecular alterations in the thymic malignancies are important to predict response and survival for novel targeted therapies. In summary, identification of genetic alterations in thymic malignancies is increasingly essential to perform molecular diagnostics and individualized treatments. This project aims to create a registry of patients with thymic malignancies to further the characterization of molecular alterations and develop (novel) treatments based on the detection.
Hyperthermic intrathoracic chemotherapy (HITOC) offers an additional treatment option for malignant pleural tumors after surgical cytoreduction. Especially it is used to further improve local tumor control in thymic malignancies with pleural spread, who underwent multimodality therapy including surgical resection. A phase II clinical study was conducted to explore the efficacy and safety of surgery followed by HITOC (POD1: DOX, POD2: cisplatin) for thymic epithelial tumors with pleural spread or recurrence.
Background: There are no approved drugs to treat recurrent thymoma and thymic carcinoma. New therapies are needed for people with these cancers. Researchers want to see if the drug PT-112 can help. PT-112 kills cancer cells. It also helps the body s immune system fight cancer. Objective: To see if the study drug PT-112 can cause tumors to shrink. Eligibility: People ages 18 and older who have thymoma or thymic cancer and whose disease returned or progressed after treatment with at least one platinum-containing chemotherapy, or who have refused standard treatment. Design: Participants will be screened with: Review of medical history and medications Physical exam Blood and urine tests CT or MRI scans of parts of the body, including the brain Participants will get PT-112 in 28-day cycles, on days 1 and 15 of of the first cycle and on day 1 of each cycle after that. They will get the drug by infusion through a catheter. The catheter is a small plastic tube put into a vein. On days they receive the drug, participants will have physical exams and blood and urine tests. They will have an ECG to test heart function on day 1 of each cycle. Participants will have scans every 8 weeks. Participants may choose to have tumor biopsies on day 1 of cycles 1 and 3. Biopsies may be guided by an ultrasound or CT scan. Participants will continue treatment as long as they can handle the side effects and their disease does not get worse, for up to 8 years. Participants will have follow-up visits 2 weeks and 4 weeks after they stop therapy. Then the study team will check on participants every 3 months until 8 years after the participant joined the study.
This is a phase II, single-arm, open-label study to evaluate the efficacy and safety of neoadjuvant Toripalimab + chemotherapy followed by radical surgery as first-line treatment in patients with locally advanced thymic epithelial tumor.
This study is an observation, single center study to evaluate the alternations and prognostic value of peripheral blood lymphocyte (PBL) in patients diagnosed with thoracic cancers, including lung cancer, esophageal squamous cell carcinoma and thymic epithelial carcinoma underwent radiotherapy with or without chemotherapy.
The purpose of this study is to determine whether stereotactic body radiotherapy (SBRT) combined with recombined human granulocyte-macrophage colony stimulating factor(rhGM-CSF) and Peginterferon alfa-2b is safe, effective in the treatment of patients with metastatic thymic epithelial tumors.
