Studies have suggested that early treatment may improve the outcome of patients with PTLD. Thus, significant attention has been focused on PCR-based approaches for preemptive (i.e., prior to clinical presentation) diagnosis. Reports from several transplant centers have demonstrated that HSCT recipients with PTLD generally have higher concentrations of EBV DNA in the peripheral blood than patients without PTLD. However, the PCR values of patients with PTLD typically span multiple orders of magnitude and overlap significantly with values from patients without PTLD. Thus, questions remain about the sensitivity and predictive value of these assays. Preemptive strategies using rituximab and/or EBV-specific cytotoxic T lymphocytes have been evaluated in patients with elevated EBV viral loads. We review the current literature, discuss our institutional experience and identify several areas of future research that could improve the diagnosis and treatment of this life-threatening disorder in HSCT recipients.10aDNA, Viral / blood10aEpstein-Barr Virus Infections / diagnosis10aHerpesvirus 4, Human / isolation & purification10aHumans10aLymphoproliferative Disorders / diagnosis10aPolymerase Chain Reaction10aStem Cell Transplantation / adverse effects1 aWeinstock, D M1 aAmbrossi, G G1 aBrennan, C1 aKiehn, T E1 aJakubowski, A  uhttps://www.notifylibrary.org/reference/1687
