View clinical trials related to Pleuropulmonary Blastoma.
Filter by: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.
Congenital lung anomalies include different pathologies such as congenital cystic adenomatoid malformation, pulmonary sequestration, bronchial atresia, emphysema, bronchogenic cyst. They concern less than 1/10000 births and their physiopathological origin is still poorly understood. The main goal of this project is to pool the cases from different swiss centers on a prospective cohort study, first to increase knowledge of clinical and radiological evolution and their correlation with histological data, and second to analyse the pathological embryological mechanism underlying these malformations.
Background: - Pleuropulmonary blastoma (PPB) is a rare fast-growing lung tumor that is associated with other, rare tumor types. Most cases of PPB appear in children younger than 6 years of age. Recently, it has been shown that this condition can be inherited (e.g., mutation of the DICER1 gene). Researchers are studying both clinical and genetic aspects of this newly described condition. They are interested in collecting further medical history and genetic information on individuals and close relatives of individuals who have PPB or other rare associated tumors. Objectives: - To study individuals with a personal or a family history of pleuropulmonary blastoma (PPB) or other rare tumors that can be associated with PPB (e.g., cystic nephroma, nasal chondromesenchymal hamartoma, ovarian Sertoli-Leydig cell tumors, ocular medulloepithelioma). Eligibility: - Individuals who have been diagnosed with PPB and/or PPB-related tumors. - Close blood relatives (e.g., parents, siblings, grandparents) of individuals who have been diagnosed with PPB and/or PPB-related tumors. Design: - Interested participants can enroll or inquire about this study by calling 1-800-518-8474. - Participants will be asked to complete family history and medical history questionnaires. They will complete the questionnaire if they are at least 18 years of age, or another person will complete the questionnaire if the key family member is too young to do so on his or her own. - Participants will be asked to sign a medical record release form to allow researchers to examine detailed medical history information. - Participants may be asked to have a physical examination and imaging studies, provide blood and saliva samples, or provide tumor tissue from prior biopsies or cancer surgeries. - Annually, participants will update the family history and individual information questionnaires to document important changes in medical history, and will also update the medical record release form. Participants may be asked to provide additional cheek lining cells and/or blood samples, as well as tumor tissue from any new or planned biopsies or tumor surgeries. - Treatment will not be provided as part of this protocol....
