DLBCL indicates diffuse large B-cell lymphoma; GCB, germinal center B-cell; ECOG, Eastern Cooperative Oncology Group; IPI, International Prognostic Index; GI, gastrointestinal; CT, chemotherapy; R-CHOP, rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone; R-ICE, rituximab-ifosfamide, carboplatin, and etoposide; HCT, hematopoietic stem cell transplantation; HCV, hepatitis C virus.
Asian or Pacific Islander.
According to composite or discordant biopsy results (lymph node and bone marrow biopsies) or a previous history of indolent lymphoma.
Stomach, liver, and/or pancreas.
