Background: Thymoma and thymic carcinoma are diseases of the thymus. Platinum-based chemotherapy is the standard treatment for these diseases. But in many cases, the disease returns after treatment. Researchers want to see if a new drug can help. Objective: To see if bintrafusp alfa (M7824) is an effective treatment for thymoma and thymic carcinoma. Eligibility: People age 18 and older who have thymoma or thymic cancer and their disease returned or progressed after treatment with at least one platinum-containing chemotherapy treatment plan. Design: Participants will be screened under a separate protocol. Their medical, medicine, and treatment history will be reviewed. They will have a tumor biopsy if they do not have a sample. Participants will get the study drug once every 2 weeks as an intravenous infusion. For this, a small plastic tube is put into an arm vein. During the study, participants will undergo the following: Medicine review Physical exam Review of their symptoms and their ability to perform their normal activities Blood and urine tests Thigh muscle scan (using MRI) Tumor assessment (using MRI or CT) Heart and lung function tests Thyroid gland test Skin assessment. Participants may have tumor biopsies. Some of their blood and biopsy samples will be used for gene testing. Participants may take the study drug until their disease worsens or they cannot tolerate treatment. Participants will have follow-up visits 2 and 6 weeks after stopping treatment. Then they will have long-term follow-up visits every 3 months. These may include imaging scans. Visits may be done by phone, with scans (if needed) done at their doctor s office.

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.

Intrathoracic Chemotherapy for TETs With Pleural Spread or Recurrence (CHOICE-2)

Hyperthermic intrathoracic chemotherapy (HITOC) offers a strategy to eliminate microscopic residual disease after surgical resection. Especially it is investigated to improve long-term survival in thymic epithelial tumors with pleural dissemination or recurrence. A prospective, multicenter, randomized phase III clinical trial (CHOICE-2) is conducted to compare the efficacy and safety of surgery combined with HITOC versus surgery alone. The HITOC regimen involves intrathoracic perfusion with doxorubicin on postoperative day 1 and cisplatin on postoperative day 2.

Electrocautery Resection Combined With HITHOC for Thymic Epithelial Tumors With Pleural Metastasis

The goal of this observational study is to explore the effectiveness of electrocautery resection combined with hyperthermic intrathoracic chemotherapy (HITHOC) in patients with thymic epithelial tumors with pleural metastasis or recurrence. The study aims to: * Evaluate whether this combined treatment improves event-free survival in patients with pleural metastasis from thymic epithelial tumors * Assess the rates of grade ≥3 treatment-related adverse events * Examine how this treatment affects patients' quality of life Participants will: * Undergo extended thymectomy with electrocautery resection of pleural metastases * Receive two cycles of hyperthermic intrathoracic chemotherapy with cisplatin and doxorubicin at 42-43°C, 2-4 days apart * Complete quality of life questionnaires (EQ-5D) at baseline and regular intervals * Have regular follow-up visits with imaging and clinical assessments for up to 36 months to monitor for disease recurrence or progression

Clinical Study of Postoperative Carbon Ion Radiotherapy for Thymus Tumor With Residual Tumor

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.

Molecular Analysis and Treatment Options of Thymic Malignancies

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.

Hypofractionated Radiotherapy for Thymic Epithelial Tumors

The goal of this clinical trial is to learn if hypofractionated radiotherapy works to shorten the treatment time without increasing the side effects in patients of thymic epithelial tumors. The main questions it aims to answer are: * Does Hypofractionated radiotherapy provide better results? * Can hypofractionated radiotherapy reduce toxic and side effects compared with conventional radiotherapy? Researchers will compare the efficacy and safety of hypofractionated radiotherapy after thymic tumor surgery. Participants will: * Receive hypofractionated radiotherapy or conventional radiotherapy * Visit the hospital regularly once every 12 weeks for checkups and tests

RATT Vs. VATT for Early-stage TETs

This study is a prospective, multicenter, phase II randomized controlled trial.

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.

Rivoceranib in Patients With Metastatic Thymic Epithelial Tumor

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.

Artificial Intelligence Prediction Tool in Thymic Epithelial Tumors

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.
