3 Clinical Trials for Various Conditions
The purpose of this study is to collect information on the effects of treatment for gestational trophoblastic disease (GTD). We plan to use the findings from this study to better understand GTD survivors' health and quality of life. We would like to know more about the health, quality of life and pregnancies of women treated for GTD. This information will be used to try and improve the treatments for women who have this disease.
The purpose of this study is to evaluate low oxygen areas called hypoxia within the tumor. These low oxygen areas are thought to be the reason why tumors are more resistant to radiation treatment. A tracer is an extremely small quantity of a substance. Tracer to which radioactivity has been attached may be used to "trace" events in the body. A tracer called iodo-azomycin galactopyranoside (or \*IAZGP) appears to be able to detect low oxygen areas within tumor. Radioactive iodine in this molecule can be detected by an imaging technique called a PET scan. This present study involves obtaining three scans using this new imaging technique. The goal of carrying out many scans is to determine which scan will best show any areas in your tumor that may have low levels of oxygen.
Pleuropulmonary blastoma (PPB) is a rare malignant neoplasm of the lung presenting in early childhood. Type I PPB is a purely cystic lesion, Type II is a partially cystic, partially solid tumor, Type III is a completely solid tumor. Treatment of children with PPB is at the discretion of the treating institution. This study builds off of the 2009 study and will also seek to enroll individuals with DICER1-associated conditions, some of whom may present only with the DICER1 gene mutation, which will help the Registry understand how these tumors and conditions develop, their clinical course and the most effective treatments.
