Real World Prevalence Of Diagnostic Revision Among Patients With Peripheral T-Cell Lymphomas (Ptcl) In The Us: Results Of An Administrative Claims And Electronic Medical Record Analyses

Introduction: Peripheral T-cell lymphomas (PTCL) are a rare heterogeneous group of lymphoid malignancies, which originate from post-thymic (or mature) T-cells. Although there are approximately 7,000 new cases of PTCL in the US annually, PTCL is extremely heterogenous and difficult to diagnose even in academic settings (Teras et al. 2016. CA Cancer J Clin 2016; 66:443-459). Prior research suggests a high rate of diagnostic revision among PTCL patients. The objective of this analysis was to describe the rate of diagnostic revision among patients with a PTCL diagnosis using 2 large, real-world US databases.
