ABSTRACT

Paraneoplastic autoimmune multiorgan syndrome is a complex and deadly disease. We retrospectively reviewed the clinical features and risk factors for para-neoplastic autoimmune multiorgan syndrome in 145 Chinese patients. The most common neoplasm was Castleman disease (56%), and patients with Castle-man disease tended to be younger (≤42 years old: 83% vs. 29%) and to have a greater proportions of lichen planus-like lesions (47% vs. 27%) and bronchiolitis obliterans (49% vs. 29%), compared to other neoplasm-associated patients. Among all 145 patients in the study, the survival rates were 84% at 1 year, 65% at 3 years, and 54% at 5 years. Kaplan-Meier curve analysis revealed that mortality was associated with older age (>42 years), neoplasm type, labial lesions, and larger skin lesion area (>17.5% of the body surface area). However, only older age and larger skin lesion area were independent factors associated with mortality in multivariate analysis. We suggest that patients with Castleman disease and paraneoplastic autoimmune multiorgan syndrome have many unique characteristics and the underlying risk factors for death require further exploration.
