Scientists hunt for clues to tell apart two Look-Alike lymphomas
NCT ID NCT07313943
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at rare lymphomas that are hard to tell apart under the microscope—some look like Hodgkin lymphoma but lack a key marker (PAX5), making them similar to another type called anaplastic large cell lymphoma (ALCL). Researchers will analyze tissue samples from 60 adults to find genetic and protein patterns that can better distinguish these two diseases. The goal is to improve diagnosis, since the two types have very different survival rates and treatments.

Inclusion Criteria: * Patients with lymphoma diagnosed as classic Hodgkin's lymphoma with a negative PAX5 marker * Patients with uncertain differential diagnosis between classical Hodgkin's lymphoma with atypical phenotype (PAX5 negative) and ALK-negative anaplastic large T-cell lymphoma (PAX5 negative) * Adult males and females at diagnosis * Availability of the molecular and/or cytogenetic data.
