Study objective: To evaluate the extent to which
high-resolution CT (HRCT) can predict the clinical outcome of
bronchoscopic treatment with curative intent in patients with
intraluminal typical bronchial carcinoid tumors.
Design: An observational study.
Bronchoscopy unit and radiology department of a university
Patients and interventions: Eighteen
patients with intraluminal typical bronchial carcinoid tumors in the
absence of nodal and distant disease were treated with bronchoscopic
electrocautery or Nd-YAG laser as an alternative to surgical resection.
Prior to treatment, HRCT was performed.
Results: In 10
patients, HRCT showed no peribronchial tumor extension, and 9 of these
patients were found to be tumor free after bronchoscopic treatment. So
far during follow-up, none of these patients has had a recurrence of
the tumor. The median duration of follow-up was 33 months (range, 13 to
68 months). In five patients, HRCT showed signs of peribronchial tumor
extension. In three of these patients, specimens taken from biopsies
performed after bronchoscopic treatment showed residual tumors, and
salvage surgery was carried out. In three patients, HRCT was unable to
assess peribronchial tumor extension: in two because of insufficient
connective tissue contrast between the hilar structures and in one
patient because of suboptimal scan technique.
Conclusion: HRCT findings were complementary but not
conclusive in patients with intraluminal typical bronchial carcinoid
tumors treated with bronchoscopic therapy. However, in a category of
patients in whom HRCT showed strictly intraluminal tumors,
bronchoscopic resection as an alternative for surgical resection seems
