International Extranodal Lymphoma Study Group (ielsg)

This study looks at tumor samples from 300 people with nodal marginal zone lymphoma, a rare blood cancer. Researchers want to find genetic patterns that help predict how the disease will behave. The goal is to better understand the disease and improve future treatment decisions.

This study is looking at a rare and aggressive form of lymphoma called transformed splenic marginal zone lymphoma (t-SMZL). The goal is to understand the genetic changes that happen when the disease transforms and becomes harder to treat. Researchers will analyze tumor samples fr…
