Abstract

BACKGROUND. The objective of this descriptive analysis of a large cohort of patients with Langerhans cell histiocytosis (LCH) was to add to the understanding of the natural history, management, and outcome of this disease. METHODS. Three hundred fourteen Mayo Clinic patients with histologically proven LCH were categorized into those patients with multisystem disease and those patients with single system disease. Clinical features, treatment, and outcome were determined from the case history notes and tumor registry correspondence. Treatment included chemotherapy, radiotherapy, and surgical excision. The end points were disease free survival, active disease, or death. The median time of follow-up was 4 years (range, 1 month to 47.5 years). RESULTS. The age of the patients ranged from 2 months to 83 years. Of the 314 patients, there were 28 deaths. Multisystemic LCH was found in 96 patients, 25 of whom had continuing active disease after treatment. Isolated bone LCH lesions were observed in 114 of the 314 patients, 111 of whom (97%) achieved disease free survival after treatment. The most common sites of osseous LCH were the skull and proximal femur. Of the 87 patients with isolated pulmonary involvement, only 3 were nonsmokers. After treatment with corticosteroids (± cyclophosphamide or busulphan), 74 patients achieved disease free survival, but 10 patients died. Pituitary-thalamic axis LCH, characterized by diabetes insipidus, was found in 44 patients. After treatment, 30 of these patients had disease free survival, but all required long term hormone replacement with desmopressin acetate. Lymph node involvement was found in 21 patients, and mucocutaneous involvement was found in 77 patients. CONCLUSIONS. Patients with isolated bone LCH lesions have the best prognesis compared with patients with LCH involvement of other systems. By contrast, 20% of patients with multisystem involvement have a progressive disease course despite treatment. The identification of prognostic indicators to facilitate appropriate treatment and long term follow-up surveillance is recommended.
