Résumé

B-cell posttransplantation lymphoproliferative disorder (B-PTLD) is a rare but severe complication of transplantation, with no consensus on best treatment practice. This prospective trial, the first to test a treatment for PTLD, was designed to evaluate the efficacy and safety of rituximab in patients with B-PTLD after solid organ transplantation (SOT). Forty-six patients were included and 43 patients were analyzed. Patients were eligible if they had untreated B-PTLD that was not responding to tapering of immunosuppression. Treatment consisted of 4 weekly injections of rituximab at 375 mg/m2. At day (d) 80, 37 (86%) patients were alive, and the response rate was 44.2%, including 12 complete response/unconfirmed complete response (CR/CRu). The only factor predictive of a response at d80 was a normal lactate dehydrogenase level (P = .007, odds ratio [OR] = 6.9). At d360, responses were maintained in 68% of patients, and 56% of patients were alive. The overall survival rate at 1 year was 67%. We conclude that rituximab is effective and safe in PTLD, with stable responses at 1 year. The response rate and overall survival might be improved by combining rituximab with other treatments.
