[Clinical Characteristics, Treatment and Prognosis of PTLD after allogeneic Hematopoietic Stem Cell Transplantation].
Zhongguo Shi Yan Xue Ye Xue za Zhi 2018 April
OBJECTIVE: To study the clinical characteristics of patients with post-transplantation lymphoproliferative disease (PTLD) after allogeneic peripheral blood hematopoietic stem cell transplantation, and to improve the understanding and diagnosis of PTLD.
METHODS: The clinical data of 244 patients underwent allogeneic hematopoietic stem cell transplantation in the General Hospital of PLA from May 2014 to April 2017 were analyzed retrospectively. The follow-up time was up to November 30, 2017. The incidence, risk factors, treatment and survival of patients with PTLD were statistically analyzed.
RESULTS: Among the 244 cases the PTLD occurred in 22 cases, the incidence rate was 9.02%, 5 of them were diagnosed by pathology, and 17 were diagnosed clinically. All of them had EB virus infection. They were all ATG user, either underwent related haploidentical hematopoietic stem cell transplantation or unrelated hematopoietic stem cell transplantation, 20 cases were treated with rituximab or rituximab combined with γ-globulin, glucocorticoid, ERV+CTL, chemotherapy and 17 showed the effective response, with a total effective rate of 85%. The median follow-up time was 122 days, the median survival time was 5 months (1-22 months) and the total survival rate was 50%.
CONCLUSION: The incidence of PTLD after allogeneic peripheral blood hematopoietic stem cell transplantation closely relates with EB virus infection. The application of ATG in the preconditioning scheme is a high risk factor for the onset of PTLD. In the case of no pathological diagnosis, clinical and laboratory examinations should be actively combined so as to define clinical diagnosis. The riturimab should be used more and more for patients with PTLD.
