Zanubrutinib, Rituximab, and Lenalidomide in the First-Line Treatment of Marginal Zone Lymphoma

A Multicenter, Single-Arm, Prospective Clinical Study of Zanubrutinib, Rituximab, and Lenalidomide in the First-Line Treatment of Marginal Zone Lymphoma

The goal of this clinical trial is to learn if Zanubrutinib, Rituximab, and Lenalidomide works to treat marginal zone lymphoma as the first-line therapy. It will also learn about the safety of the treatment. The main questions it aims to answer are Does the combined therapy prolong patient survival? What medical problems do participants have when using this therapeutic approach? Researchers will observe the treatment to see if it works well than conventional therapies.

Participants will Administer drugs as required by the protocol Visit the clinic regularly for checkups and tests Keep a diary of their symptoms, examination and laboratory test indicators
