RecruitingIntegrated Molecular and Clinical Profiling of Transformed Splenic Marginal Zone LymphomaHistological transformation in Splenic Marginal Zone Lymphoma (t-SMZL) represents an unmet clinical and biological need, invariably associated with poor prognosis and reduced overall survival. At the present time, there are no recommended treatments intended specifically to t-SMZL and little is known about t-SMZL genetic complexity. The aim of this study is to provide information that will help clinicians to better understand the complexity of the disease. The information gained from this study will also lead to more specific and effective treatment for patients with t-SMZL.
