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.
This is a prospective, single-center, non-randomized phase II study. Patients with germ cell tumors of gonadal and extragonadal localization who have progressed after prior platinum-containing first-line chemotherapy will receive high-dose chemotherapy with TI (2 cycles) folollowed by high dose CE chemotherapy with autologous stem cell transplantation (3 cycles). The primary endpoint of the study is to evaluate the efficacy high-dose chemotherapy as second-line drug therapy for patients with advanced germ cell tumors.
The primary purpose of this study is to determine whether the investigational drug XmAb541 is safe and well tolerated, and to determine an optimal and safe dose(s) for further study. The study will also evaluate effect of XmAb541 on tumor outcomes.
Robot-assisted image-guided sentinel lymph node biopsy (RAISN) in testicular cancer is a novel technique that has not been widely investigated yet. This technique is promising and could be implemented as a future standard in the primary diagnostic work up of clinical stage (CS) I testicular cancer. Current staging strategies have a poor predictive accuracy for occult metastatic disease. So far, feasibility studies used 99mTC-nanocolloid staining and laparoscopy and all patients with tumor-positive nodes received adjuvant systemic treatment. The development of a robot-assisted image-guided lymph node resection technique with indocyanine green (ICG) is potentially more precise, easier to apply and widely available. With this new diagnostic approach the management of newly diagnosed testicular cancer patients might be changed dramatically by reducing overtreatment and treatment-related toxicity with a minimally invasive robot-assisted procedure.
Intensified chemotherapy is an effective treatment in 30-70% of patients with refractory germ cell tumor. Since most cases are diagnosed before the age of 40, survivors can expect to live another 30 to 50 years after being successfully treated. Long-term side effects and physical and emotional consequences can therefore have a significant impact on daily life. To date, no data of this type is available in France. This study will help clinicians better understand the long-term consequences for relapsed patients receiving high-dose chemotherapy.
The goal of this clinical trial is to assess the efficacy of thromboprophylaxis in preventing venous thromboembolic events (VTE) in good and intermediate prognosis patients with metastatic germ cell cancer (GCT) undergoing first-line cisplatin-based chemotherapy with risk factors for developing a thromboembolic event . The high-risk patients will be randomized between two treatments arm (receiving a thromboprophylaxis in the experimental arm, or no thromboprophylaxis in the control arm). The low-risk patients will be observed without any thromboprophylaxis. Patients will participate in the study for 14-17 weeks depending on the planned number of cycles of chemotherapy. Researchers will compare an experimental arm with thromboprophylaxis and a control arm without thromboprophylaxis to detect an absolute decrease of 12% of the proportion of patients having experienced a VTE, from 21% (high risk patients, control arm) to 9% (high risk patients, experimental arm).
Primary malignant central nervous system (CNS) tumors are the second most common childhood malignancies. Amongst, medulloblastomas are the most common malignant brain tumor of childhood and occur primarily in the cerebellum. According to molecular characteristics, medulloblastomas were classified into four subtypes: WNT, SHH, Group3 and Group4 and different prognosis were noticed between subgroups. Several genetic predispositions related to clinical outcome were also discovered and might influence the treatment of medulloblastomas as novel pharmaceutical targets. This study aims to investigate genetic and cellular profiles of pediatric brain malignancies, mostly medulloblastomas, and other central nervous system tumor based on WGS, RNA-seq, single-cell sequencing and spatial transcriptomics. We also aim to investigate the correlation between genetic characteristics and clinical prognosis.
This is a phase 2 research study that enrolls adult subjects with Nonseminomatous Germ Cell Tumors (NSGCT). The purpose of this study is to create a repository and explore the presence of modified T cells in the subject's plasma or tumors. This study collects biospecimens (such as tumor tissue, blood, and modified T cells) that can be used in future research studies. The collected specimens can help to examine whether the modified T cells are present in the body and tumor. If the modified T cells are present in the body, and how long they last. They also will use the specimen to identify ways to improve treatment options for a future cancer patient. Research with blood, tissue, or body fluids (specimens) can help researchers understand how the human body works. Sometimes researchers collect and store specimens and use them for different kinds of research or share them with other scientists; this is called a specimen repository or "biobank." Research with biospecimens might help to introduce new tests to find diseases or new ways to treat diseases. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancer. This research study combines two different ways of fighting disease: antibodies and T cells. Antibodies are proteins that protect the body from disease caused by bacteria or toxic substances. Antibodies work by binding those bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including tumor cells or cells that are infected. Both antibodies and T cells have been used to treat patients with cancers. They both have shown promise, but neither alone has been sufficient to cure most patients. This study is designed to combine both T cells and antibodies to create a more effective treatment called autologous T lymphocyte chimeric antigen receptor cells targeted against the CD30 antigen (ATLCAR.CD30) administration. Prior trials have shown the safety of ATLCAR.CD30 product was administered to subjects with lymphomas. This study was planned based on the safety and efficacy data from previous studies (NCT02690545 and NCT02917083).
A Non-Therapeutic Study that aims to establish a cohort of GCT survivors to understand short term and long-term adverse effects of treatment and to conduct molecular analyses to improve risk stratification.
