About this study

This trial is testing if rituximab with etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (R-EPOCH) is beneficial for people with high-risk B-cell PTLD during their second phase of treatment. It's also evaluating the use of circulating tumor DNA (ctDNA), a blood test that may help guide treatment decisions in lymphoma patients, to see if it can be used to personalize treatment and reduce side effects without losing effectiveness.

Based on ClinicalTrials.gov records.
