Summary
Brief summary (as posted)
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.

- label
- Type I PPB
- description
- Type I PPB is an early manifestation of this malignant disease, cured in some cases by surgery. Surgical guidelines are presented. It is unknown whether adjuvant chemotherapy improves cure rates for individuals with Type I PPB. If the treating physicians select adjuvant chemotherapy treatment, chemotherapy options include a 22-week regimen: 4 courses of vincristine, actinomycin D and cyclophosphamide (VAC) followed by 3 courses of vincristine and actinomycin D (VA). Therapy decisions are the responsibility of the treating institution.
- label
- Types II and III PPB
- description
- Types II and III PPB are aggressive sarcomas. Surgery and chemotherapy are necessary in all cases. Surgical guidelines are presented. Many children with Types II or III PPB receive a single-arm multi-agent chemotherapy neo-adjuvant/adjuvant regimen of IVADo (ifosfamide, vincristine, actinomycin, doxorubicin) for 36 weeks. Second and possible 3rd look surgery may be considered for local control. Radiation therapy may be considered. Specific therapy decisions are the responsibility of the treating institution.
- label
- Type Ir PPB
- description
- Type Ir (regressed) PPB is a unique, purely cystic tumor which lacks a primitive cell component. The International PPB/DICER1 Registry will enroll and follow participants with Type Ir PPB, regardless of age.
