A Study of Lower Radiotherapy Dose to Treat Children With CNS Germinoma
Recruiting
This phase II trial studies how well lower dose radiotherapy after chemotherapy (Carboplatin \& Etoposide) works in treating children with central nervous system (CNS) germinomas. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by... Read More

A Study of Treatment for Medulloblastoma Using Sodium Thiosulfate to Reduce Hearing Loss
Recruiting
This phase III trial tests two hypotheses in patients with low-risk and average-risk medulloblastoma. Medulloblastoma is a type of cancer that occurs in the back of the brain. The term, risk, refers to the chance of the cancer coming back after treatment. Subjects with low-risk medulloblastoma typically have a lower chance of the cancer coming back than subjects with average-risk medulloblastoma. Although treatment for newly diagnosed average-risk and low-risk medulloblastoma is generally effect... Read More

This phase III trial compares the effect of open thoracic surgery (thoracotomy) to thoracoscopic surgery (video-assisted thoracoscopic surgery or VATS) in treating patients with osteosarcoma that has spread to the lung (pulmonary metastases). Open thoracic surgery is a type of surgery done through a single larger incision (like a large cut) that goes between the ribs, opens up the chest, and removes the cancer.

Active Surveillance, Bleomycin, Etoposide, Carboplatin or Cisplatin in Treating Pediatric and Adult Patients With Germ Cell Tumors
Recruiting
This phase III trial studies how well active surveillance help doctors to monitor subjects with low risk germ cell tumors for recurrence after their tumor is removed. When the germ cell tumor has spread outside of the organ in which it developed, it is considered metastatic. Chemotherapy drugs, such as bleomycin, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from sp...

Genome Transplant Dynamics
Recruiting
Study Description: Heart and lung transplants can save lives, but long-term success is often limited by organ rejection that is hard to detect early. This study is testing a new, non-invasive blood test that looks for small pieces of DNA from the donor organ in the patient s blood. We believe higher levels of this donor DNA may signal early rejection before damage becomes permanent. Hypothesis: We believe that measuring donor-derived DNA in the blood can help detect early signs of rejection a... Read More

Developing a Tailored Psychosocial Education Intervention for Chronic Pain Management for Asian Americans
Recruiting
Health inequalities in chronic pain exists in the US, with a greater burden of chronic pain and higher rate of misdiagnosis and undertreatment reported in minoritized groups compared to non-Hispanic Whites. Asian Americans (AA) are the fastest-growing racial/ethnic group in the US, yet despite the rapid growth in their numbers, AA remain under-represented in pain disparity research. Cultural norms of Asians may discourage reporting their pain to avoid burdening others or being seen as weak. Rath... Read More
