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 About How Blood Cell Growth Patterns Relate to Heart Health After Treatment for Hodgkin Lymphoma
Recruiting
This study assesses how blood cell growth patterns (clonal hematopoiesis), relates to heart health or cardiovascular disease (CVD) after treatment in patients with Hodgkin lymphoma. In some patients, cancer treatment at a young age may lead to later complications, including problems with heart health. Checking for blood cell growth patterns called therapy-related clonal hematopoiesis (t-CH) can help predict who might be at risk for heart health problems after Hodgkin lymphoma treatment. If docto... Read More
