Rare lymphoma transformation under study: what happens when aggressive cancer comes back mild?
NCT ID NCT06822829
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at a rare event where an aggressive lymphoma (DLBCL) comes back as a slow-growing (indolent) lymphoma. Researchers will review medical records of 50 adults to understand how often this happens, what treatments are used, and how well patients do. The goal is to gather information to help guide future care for this uncommon situation.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study will be proposed to patients diagnosed with diffuse large B-cell lymphoma (DLBCL) who have relapsed as indolent B-cell lymphoma, with a histologically confirmed diagnosis of relapse and availability of the histological report. Patients who are still alive will be contacted and informed by the specialist about the study's objectives and will be required to sign a specific informed consent form. For patients lost to follow-up or deceased, a waiver of informed consent has been obtained from the Ethics Committee in accordance with applicable regulations.
