Overview
The long-term outcomes of adult patients with pulmonary Langerhans cell histiocytosis (PLCH), particularly survival, is largely unknown. This is the first prospective study in the field evaluating the long-term outcomes of PLCH patients. This french countrywide registry-based study included a large cohort of PLCH patients followed for a sufficiently long period to address risk factors of long-term outcomes of PLCH patients.
