The Double Hit Lymphoma Patient Registry represents a collaborative effort to connect patients, caregivers and clinicians around the world. Our registry has three primary goals: Develop a community of people impacted by double hit lymphoma who may serve as sources of inspiration and hope to others; provide insight on what additional resources are needed by patients and clinicians and a channel through which we can deliver those resources; and assist, accelerate and support research into earlier and more comprehensive diagnosis and treatment of double hit and other MYC-related lymphomas.
