Triptorelin for the Prevention of Ovarian Damage in Adolescents and Young Adults With Cancer
Recruiting
This phase III trial compares the effect of giving triptorelin vs no triptorelin in preventing ovarian damage in adolescents and young adults (AYAs) with cancer receiving chemotherapy with an alkylating agents. Alkylating agents are part of standard chemotherapy, but may cause damage to the ovaries. If the ovaries are not working well or completely shut down, then it will be difficult or impossible to get pregnant in the future. Triptorelin works by blocking certain hormones and causing the ovar... Read More

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
