Pleuropulmonary blastoma (PPB) is a rare and potentially aggressive intrathoracic disembryonic neoplasm typically occurring in children less than 6 years of age. We assessed the relative incidence, clinical characteristics, treatment outcome, and the prognostic factors for long-term survival in patients with PPB treated at our institution over a 25-year period, and compared these data with reports in the literature. From 1985 to 2010, 11 children (4 males and 7 females), with a median age of 5.4 years (range, 1-12 years) were treated at our hospital. Here we described the main characteristics of these patients, the diagnostic methods, and treatment modalities used. During a median follow-up period of 80, 9 months, the overall survival (OS) and disease-free survival (DFS) rates were 54, 6% and 45, 5%, respectively. Two patients survived for more than 20 years. The main prognostic factors for long-term survival were the diseases type I and II and treatment with radical surgery. Our results show that in order to improve the prognosis of patients with PPB a timely in our opinion and accurate diagnosis needs to be established and treatment should be offered according to the disease type and extend of dissemination.
