In brief
Eleven-year retrospective study of 51 pediatric patients undergoing resection for CPAM or PPB found that asymptomatic CPAM patients had significantly shorter hospital stays and chest tube duration compared to symptomatic patients. Two PPB cases were misdiagnosed preoperatively as CPAM, emphasizing the need for low threshold for resection when differentiation is unclear.
Written by the GCMD Library team from the article.
Purpose The purpose of this study is to describe a single institution's 11-year experience treating children with congenital pulmonary airway malformations (CPAMs) and pleuropulmonary blastoma (PPB).
Methods An institutional database was sampled for all patients aged 0 to 18 years from January 1, 2005, to December 31, 2015. Patients with a pathologic diagnosis of CPAM or PPB during this period were reviewed.
Results A total of 51 patients with a pathologic diagnosis of CPAM (n = 45; 88.2%) or PPB (n = 6; 11.8%) underwent surgical resection. Among patients treated for PPB, one death occurred approximately 13 months after diagnosis. Although four patients with PPB (four out of six; 66.7%) had radiographic indicators highly suggestive of malignancy prior to surgery, two had a preoperative diagnosis of CPAM (two out of six; 33.3%). Twenty-four patients (24 out of 45; 53.3%) with CPAM underwent resection after developing symptoms and 21 (21 out of 45; 46.7%) were symptomatic at the time of surgery. Mann–Whitney's tests revealed a statistically significant difference in postoperative length of stay (median: 6 vs. 3 days; p < 0.001) and days with thoracostomy tube in place (median 3 vs. 2 days; p = 0.003) for symptomatic versus asymptomatic patients, respectively.
Conclusion CPAM patients appear to recover faster from surgery, if performed before the onset of symptoms. There may be a benefit to waiting until at least 3 months of age to complete resection in the asymptomatic patient. A low threshold for resection should be maintained in patients where delineating CPAM from PPB is difficult.
