Abstract

Aim

After treatment with inhaled budesonide for 1 year, non-solid and partially solid lung nodules detected by low-dose computed tomography (LDCT) and not immediately suspicious for lung cancer, tended to regress in a randomized phase IIb, placebo-controlled trial, nested in the COSMOS lung cancer screening study. Because some of these nodules may be slow-growing adenocarcinoma precursors, we evaluated long-term outcomes by annual LDCT.

Methods

We analyzed the evolution of target trial nodules detected by LDCT in the budesonide and placebo arms up to five years after randomization. The numbers and characteristics of lung cancers diagnosed during follow up were also analyzed.

Results

The mean diameter of non-solid nodules reduced significantly (2.42 mm reduction in five years) in the budesonide arm; there was no significant size change in the placebo arm. The mean diameter of partially solid lesions also decreased significantly, but only by 0.69 mm. The size of solid nodules did not change. Neither the number of new lesions nor number of lung cancers differed in the two arms.

Conclusions

Inhaled budesonide given for one year significantly decreased the size of non-solid nodules detected by screening LDCT after five years. This is of potential importance since some of these nodules may progress slowly to adenocarcinoma, however further studies are required to assess clinical implications.
