Area of Science:

  • Pediatric Oncology
  • Pulmonology
  • Radiology

Background:

  • Lymphomas are common childhood malignancies, often involving the mediastinum.
  • Mediastinal tumors in children pose a risk of airway obstruction during anesthesia.

Purpose of the Study:

  • To quantify airway obstruction and tracheal compression in pediatric Hodgkin's Disease (HD) and non-Hodgkin's lymphoma (NHL).
  • To assess the functional significance of tracheal compression in children with mediastinal lymphomas.

Main Methods:

  • Study included 51 children with HD and NHL.
  • Pulmonary function tests (FVC, FEV1) and tracheal compression measurements were performed.
  • Comparison between HD and NHL groups, symptomatic and asymptomatic patients, and large vs. small mediastinal masses.

Main Results:

  • NHL patients had significantly worse pulmonary function (FVC 66% vs. 85% for HD).
  • Respiratory symptoms were more common in NHL (76%) than HD (30%).
  • Large mediastinal masses correlated with decreased pulmonary function and increased tracheal compression (44% vs. 27%).

Conclusions:

  • Children with mediastinal lymphomas exhibit obstructive and restrictive pulmonary deficits.
  • Pulmonary function is notably impaired in NHL patients, those with respiratory symptoms, and large mediastinal masses.
  • Tracheal compression extent directly correlates with mediastinal mass size.
