Abstract

Background: Our aim is to identify the long-term relapse-free rate and predictive factors of response to splenectomy in adults with idiopathic thrombocytopenic purpura (ITP).

Methods: Between 1999 and 2005, 54 patients of ITP, who underwent splenectomy in Chang Gung Memorial Hospital, Linkou, Taiwan were retrospectively reviewed. Various pre, intra and postoperative factors were analyzed to determine the predictive factors of response and long-term disease-free rate after splenectomy in adult patients.

Results: The relapse free survival rates in complete response patients of splenectomy at 1-, 3- and 5-yr are 91.9%, 88.4%, and 88.4%, respectively. Younger age, response to steroids, pre- and postsplenectomy high platelet counts were found to be have significant p value of < 0.05 as predictive factors in univariate analysis. In multivariate analysis, only pre-op and post-op platelet counts were significant.

Conclusions: Significant long-term relapse-free survival rate is achieved by splenectomy in adults with ITP. In univariate analysis, age, response to steroids, pre- and postsplenectomy platelet counts were the significant predictive factors of response. But in multivariate analysis, only pre-op and post-op platelet counts were significant.
