Minimal Residual Disease in Peripheral T-cell Lymphoma

As T-cell receptor sequencing by LymphoTrack is an assay with high sensitivity that can be performed in peripheral blood, the investigators wish to evaluate the ability of this assay to predict which patients are at higher risk of relapse after initial therapy for peripheral T-cell lymphomas which is being given for curative intent. Additionally, as more is known about the ability of dynamic monitoring of cfDNA in B-cell lymphomas to predict relapse, the investigators wish to explore the use of this technology in T-cell lymphomas.
