Synopsis:
Patients with diffuse large B cell lymphoma (DLBCL) were sub-classified by immunohistochemical method to evaluate the effects of subgroups on prognosis. The lymph node biopsy specimens of 40 patients with DLBCL were stained with monoclonal antibody immunstains of CD10, Bcl-6 and MUM1. Finally, MUM1 was found negatively correlated with overall survival and event-free survival.
