The authors considered the panel’s confidence in the estimated effects, the balance of benefits versus harms and burdens of treatment, patient values and preferences, cost, and feasibility, and formulated recommendations for or against specific interventions. Recommendations included treatment with sirolimus rather than observation for patients with LAM with abnormal/declining lung function, and treatment with sirolimus before invasive management for selected patients with LAM with problematic chylous effusions. Vascular endothelial growth factor D testing was recommended to establish LAM diagnosis before consideration of diagnostic lung biopsy. Doxycycline and hormonal therapy were not recommended for LAM treatment.
