ABSTRACT
OBJECTIVE@#To observe the clinical and laboratory characteristics of adult Langerhans cell histiocytosis(LCH) patients and to analyze the influencing factors of its prognosis.@*METHODS@#The clinical and laboratory charac-teristics of 38 adult LCH patients treated in our hospital from January 2010 to August 2019 were retrospective analyzed, and the clinical prognosis of the patients was analyzed.@*RESULTS@#The median age of 38 patients was 41 (21-65) years old, and the ratio of male and female was about 2∶1. Among 38 patients, 44.7% (17/38) were involved in multiple systems, and 31.6% (12/38) were involved in high-risk organs (including liver, lung, hematopoietic system or spleen). The bone involvement was the most common (21/38, 55.3%), and the most common clinical symptom was pain (19/38, 50.0%). The result of laboratory showed that anemia (4/38,10.5%), thrombocytopenia (1/38,2.6%), neutropenia (2/38,5.3%), lymphopenia (6/38,15.8%), monocytosis (11/38,28.9%), C-reactive protein increasing (6/21,28.6%), erythrocyte sedimentation rate increasing (10/18, 55.3%), and ferritin protein increasing (9/17, 55.3%). The median follow-up time was 53 months, and a total of 5 patients were died. The 10-year overall survival rate of patients with single-system involvement was 100%, which was significantly higher than that of patients with multiple-system involvement (70.1%) (P=0.0078). The prognosis of patients without risk-organ involvement was better than that of patients with risk-organ involvement (10-year overall survival rate 100% vs 60.6%) (P=0.0007). Further analysis showed that in addition to multiple-system involvement and risk-organ involvement, the increase of peripheral blood monocyte cells and the increase of ferritin protein were also associated with poorer prognosis of the patients.@*CONCLUSION@#The multiple system involve-ment and risk-organ involvement, the increasing of monocyte cells and the increasing of ferritin protein were the independent risk factors of adult LCH patients.
