Summary
Brief summary (as posted)
The purpose of the study is to investigate the proportion of the cell-of-origin (COO) subtypes in relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) treated with BTK inhibitor or lenalidomide and its biosimilars.

Inclusion Criteria: 1. Histologically-confirmed diagnosis of DLBCL, including transformed large B-cell lymphoma from previous indolent lymphoma. 2. Meet the definition of relapsed/refractory DLBCL. 3. Patients received BTK inhibitors and/or lenalidomide and its biosimilars after the failure of the first-line standard treatment. The efficacy was evaluated by the investigators. Cohort plans to enroll one hundred patients with BTK inhibitors treatment (excluding the combination with lenalidomide), one hundred patients with lenalidomide treatment (excluding the combination with BTK inhibitors) and any number of the cases with BTK inhibitors and lenalidomide combination. a) BTK inhibitors include ibrutinib, zanubrutinib and acalabrutinib 4. Patients with comprehensive history information and follow-up data. 5. Patient able to provide written informed consent, agreeing that the donated samples and related information can be used for all medical research. Exclusion Criteria: 1. The archived tumor tissue is too little to test. 2. Patients with primary central nerve system large B-cell lymphoma or primary mediastinal large B-cell lymphoma. 3. R/R DLBCL patients receive BTK inhibitor or lenalidomide treatment for less than one cycle.
